Slug finally ready for dyno.. motor pics

[HEAVYBOAT]

Worked through all the bugs, and ready for the dyno. Final flow numbers, 450 intake,325 ex at .800

Ok Heavyboat, Lets hear the pre dyno predictions.
p.s. It might help if you bolt on the blower and INJECTOR HAT first. :)

And put the distributor on the right end

[cstraub]

Max lift numbers look good, but the ones that count are at .250", 350", and .450". Thats where the power is made.

Dam..I knew I forgot something.
Dyno predictions? First off, I have to smash the original de tuned quad whipple SLUG record at 7 pds of boost.I think it was 950hp.. the 70's technology roots will go...........
1060 hp 7 pds at 6400 rpm
Now,peak power?
I really dont know.... its gonna make some good power with 10 or 12 psi.
Lets wake up MR Moderator.
Info, lets bet a 12 pack of beer cans (shipping included)on whos closer.. most power I can make with a carbed 871 burning Gas.
This yr, Im going to run C12
I will disclose pulleys, combo ect
You in? :cool:

sorry, what can you tell me with these then?
IN........................EX
.200 166(24 gain) 135.6 (9 gain)
.300 241(28gain) 178.9 (16 gain)
.400 312(41 gain 226.7 (22 gain)
I realize the low lift numbers initialize the movement of the air .. And fundamentally that is very important, but we need to keep the air flowing as the volume increases as well, therefore I would venture to say high lift numbers are equally as important.
If I was to list total cfm airflow, even know its more informative, most guys wouldn’t care.

Dude, when are you going learn, world round the camp fire is there a throw together 502 in the 1000hp range.:p
What size is that ford agian?

[Infomaniac]

Wow what did I miss?
I do not wish to compete with a race gas deal. You can have it by default. That is how much faith I have in your ability. :)
Here is the part where I make excuses. Look again at the BSFC of my 7 lb dyno pull. It was jetted for 12 lbs. Way fat and on pump gas.
And it was 970 HP :D

Why would that matter on a blown dealio, the intake is under pressure.:confused:

WTF, speaking of faith.. I have none in your reading abilitys.
For the beer challenge it was just "guessing my hp number" nothing more. When I reread my post it seems pretty clear?
forget bout it, american beer is to weak for me anyway

How much boost did they run on the “thrown together 502” to make the 1000? I thought so… please drive through.
"When am I gonna learn"
My reason for posting this thread was to share my excitement with others pertaining to my new combo. Dyno day was coming and its always fun(well maybe not here) to guess peoples hp numbers before D day.

Look harder, the ex flow numbers are listed as well. Intake flow numbers were there for intake to exhaust ratio calculations.
When are you gonna learn?
ps that confused smiley works well for you.

And you’re bragging about that? Man, peoples phobias still astound me.. You can machine a block and assemble it, but your too intimidated to change jets? Let me know when your in the room again, I’ll get my sister to come help ya. ;)

[Infomaniac]

My reading abilities sucked last night HEAVYBOAT Had 14 of those pocket bikes show up and people waiting in line to buy them. I insist on putting them together and starting them before I let them go. I was pretty tired.
Tell your sister if she would have been there maybe she could have figured out why the thing was not making the boost. Had 2 sets of pulleys. Was using the wet exhaust from the boat. An exhaust elbow blew off on every pull except one from the weight of the dyno room exhaust pipe. Was walking around in a 1/2" of water. Well I guess you had to be there. :cool: Was a bit frustrated.
I can always fly up and help with yours. :D I operated 2 different dynos for a number of years.
Ok lets start this thread over
When is dyno day? Let me collect my thoughts and I will be happy to do the predict number beer thing . It would be fun.
You might need to share a little more info about the engine.

[cstraub]

Whether NA or "huffed" all engine have a "threshold" at which the aiflow of the head, with or without boost, reach maximum fill rate. Low to mid lift numbers are used to calculate camshaft profile. So from what you have listed I can tell you that the optimum split on duration for this engine is 8 degrees difference favoring the exhaust.

I have a question... What dyno will you be using? Will you load the motor down or let it flash to get those really good internet #'s?:confused: I see a lot of different results from dyno's & operators & it seems to me that the fashion is to flash & show huge #'s to make the customer happy!

[superdave013]

Ya, the dyno I use is all about misleading their customers.
They even had 4 engines running at Daytona last weekend in the Busch race, and rumour is... his customers are pissed cause they ALSO must have got the INTERNET numbers your talking about.Yup.... they were told they should have had enough hp to get 20 more mph at Daytona then Dale Jr!!
Its so tough finding a reputable dyno shop nowadays, they can trick us racers so dam easy….. cause we have no way of confirming what we were told. :rolleyes:

Apparently you haven't heard about the forum rules regarding engines.
1. dont come here and be happy about your motor. that's not allowed.
2. dont quote dyno sheets because no one will believe you.
3. If the worlds most prominent engine builders aren't using your combination, then you can't be making the hp you claim.
4. you should know by now that dynos always lie because alot of folks on the internet say so. lol "internet numbers" that's a good one. almost as good as "magazine numbers".
Dont let it get to you. Some of the folks that'll call bs are a couple sandwiches short of a full picnic.

Well lets see... where do I start??? First off I was asking a very honest question, with no intent on raining on anybodys parade! I don't think the reply was neccessary but what ever! Cyclone no need to get your panties in a bunch. I am very happy for you too! I am simply stating a fact that most people don't want to acknowledge. All dynos aren't the same! I know for a fact that different operators can get different results... That my friend is just a simple fact. Now with Mr Heavyboat asking for guesses on hp I was simply asking so I could make a guess too! Didn't mean to hit a nerve! By all means dyno away & good luck! I guess 1500 hp +!:D

[MAXIMUS]

Oh yea & by the way this was a really impressive statment!!
They even had 4 engines running at Daytona last weekend in the Busch race

1510 HP.

Ok then
So far we have these bets...One case of beer each :eek:

Funny Barry Maxilow,
you must be in Heaven, a Ford and a blower!!!:eek: :eek:
My 1510 was with 24 lbs boost at 8500.
my real guess is.........
12 lbs boost, 110, 6400, 900HP:p
Hey Maxipad, is that water pounding, 2000 rpm surging, asshole puckering, suck boat ready for BBSP?:confused:

My old combo with the street heads,cam and mild blower already made 940+ hp WITH 7PDS OF BOOST!!
My guess with the new heads and new blower 1180hp

Sorry just saw your questions.
Motor is a 547. Static is 9.1
Because of Duration of cam it should make good power up to 6800/7000 rpm.
New stage4.5 Bds airloc rotors blower(double stripped)
Superchiller intercooler,two 1320 cfm doms
268 intake,278 ex @.050 750ish lift
340cc TFS heads, peak cfm 450in ,325ex at .800
That should do it
:D

[Freak]

Who did your head work and any special reason why you went with those and not c-460 or ex514's?

[HEAVYBOAT]

Charlie Evans a Ford guru who made a C&C program for the TFS A460's gave detailed instructions on what to do with the A's. They came out exactly like he suggested they would.
The ex514's are a basically a copy of the TFS A's so it would be like spliting hairs finding the better head. The deciding factor was the larger combustion chamber on the TFS for low compression for the blower. The ex's are 84 cc.
http://www.flowtechnologies.net/index.php?id=359
If your into flow numbers, heres a comparsion with my heads and the ex514's. I have seen a little better numbers on the 514's before, but within a few percent.
http://66283.150m.com/TheHookup/ExcellChartA_HeadsPortedCharlieEvansRevised.jpg
Now as far as the C460 goes, for one... they require jesel type rockers and secondly they also have to small of a combustion camber for my blower application. Sure would have been nice though to utilize the extra bolt holes that the C head has. :mad:
Found some ported C460 head flow numbers
Typical hand ported with 45* seats.
Intakes
.200=158, .300=238, .400=316, .500=384, .600=431, .700=464, .750=476, .800=480
Exhausts
.200=125, .300=164, .400=212, .500=270, .600=295, .700=315, .750=320, .800=325
Our CNC program with 45* seats
Intakes
.200=160, .300=245, .400=327, .500=400, .600=450, .700=478, .750=490, .800=500
Exhausts
.200=130, .300=170, .400=210, .500=280, .600=315, .700=340, .750=347, .800=355

[Unchained]

Heavycar,
It's great that you've got all those dandy flow numbers and I bet those heads would really add a lot of performance......in a N/A application.
With a blower those beauty heads with all the extra porting work may not make much difference from the previous heads that you ran.
Your HP increase at the dyno from your previous setup will be a factor of what boost you can make now as compared to your old engine. And that will be partially offset by the additional HP required to turn the stripped blower at a higher OD.
Good luck and take a video of your dyno pulls

[HEAVYBOAT]

Unchained... I couldn’t disagree with you more. And I wish you would stop spreading that poison. :D Cylinder head flow is just as important in a blown application as N/A.. when the person’s goals are MAX EFFORT.
The old school statement " you don’t need a good head with a blower" is a fallacy. It’s a generalization that is misused all the time and cant blanket all performance levels. It can hold some merit in the right situation,like when someone just wants roots 600/700hp small block or 800/900 hp out of a big block. Then they can use their stock head and pass on the good cylinder heads. Try to make a lot more hp when your blower is maxed out and your using a roots on gas.. your back to caring about air dynamics.
My old 940 hp combo, only had 221 cfm ex flow at .800! Or total cfm (.200 through .800) 1689 cfm. My new heads flow OVER 100cfm more at .800. Or if you want to look at total cfm airflow on the ex , the new head flows 524 total more cfm on the ex (2213cfm) over my edelbrock rpms :eek: Because of the good intake port, All we did is roll paper sand the intake, just a light clean up to get the 450 cfm .. all the "DANDY WORK " like you like to call it.. work was concentrated on ex port. My guess for improvements just using this new head alone is 80 more hp. Many blower professionals are saying the same.
I proved this point this summer on my buddy’s truck. He runs a 406 chevy with a gm style blower in a 4000pd truck. He ran 111 mph with the cast 2.02 16.0 camel back stock type head. We borrowed a set of ported victor jr’s ,( same cc size) no other changes, but the headers needed for the ex port and ran it the following weekend. 117 mph. My math tells me that was 55 more hp!
Now I know you make insane hp and boost with your turbo deal unchained, and you may not want any more then you already have,(must be nice) but when or if you reach that “point” when your turbo compressor is maxed out…, that combo would benefit from a more efficient cylinder head.

[Unchained]

Well it will be easy to prove me wrong.
While the motors on the dyno run the new motor at the same 7 lb boost and rpm as the old one and see what it produces.
By the way what is the lobe centers of your new cam as compared to the old one?
If I'm wrong I'll send you a picture of a 12 pack of Molson's :D

Now THAT would be real interesting.

[Infomaniac]

How much overdrive to get 7 lbs?
My guess.
1,073 HP @ 7,000 RPM if using 12% overdrive.
A bit under your guess. I think that cam wil make power past 7,500. When is Dyno Day?

[HEAVYBOAT]

I can get the 7 psi I promised for the comparison. I can set up 1 to 1 ,5% , 8%, 15% and 20. Under or over of course to get what we need.
Actually I was originally planning on dynoing the slug yesterday, but I had some family come in town to see my newborn. I found some time today in the garage to install the drive,carb adapter,carbs and linkage on the new blower. Then when I drive up, probably Thurs or Fri, I'll just plunk the whole assembled abortion on the manifold, hook up the fuel lines and crank her up INFO style!!
12 percent overdrive?. I wonder how much boost I would be making now at that overdrive. Last combo made right around 7 or 8 psi, so this yr.. I wouldnt be surprised to see 4 maybe 5 more (13 psi )or more with the strips and airlocs. Thats taking into consideration that the new heads are going to flow more therefore buiding less pressure in the intake.
The extra 5 psi in theory should give me 150hp if the combo is there to support it. 940+150 =1090hp. emm not a bad guess you had there Info. :D
If everything goes well, that 20percent overdrive is gonna finish off the dyno day..

Now he's calling you havnothing???:D lol... I may have to kick it up a notch?;) I say run a "full race" intake lobe & a "3/4 race" exhaust lobe & quit screwing around with those small heads! That should make it run like a chevy then...:eek:

Gonna have to wait, they are worried the FORD 3/4 race cam might break their dyno, so they are ordering billet couplers and a forged bellhousing.
I'm booked in for Friday morning. Its a bit of a drive, so it makes for a long day.

Ok finally you lightend up a bit! Good humor too! Good luck to you & please do post. I am a ford guy...shhhhhhhh don't tell! Also for some fun slightly off topic but a good filler until we get some results, what the hell is a 1/2, 3/4, or full race cam & where did this ever start?:confused: Blown is that what u run down south?:D

I have no idea what 3/4 race cam means.. I use to hear my Dad use the term when I was a kid. We all know someone old enough here that could probably fill us all in.
INFO... help us out :D
And from what I understand, budjet472 just drives a minivan and a torn apart junker boat. :eek:

My in house mechanic is a good ol boy from Kansas. Every story that Henry tells about fast cars or shine runners from "the day" all had "FULL BLOWN CRYSLERS" or duals with a 3/4 race cam... lol I don't believe he really ever owned anything exciting himself. So my brother & myself took his 70 Ranchero (429GT) & install a new 429 dove motor with a tunnel ram & dual 600's. We cut a hole in the hood & finished the car off with some black steel rims, chrome lugs & raised white letter tires! The car runs very well & I swear is the best thing that ever happend to him! Sorry for the long boring story...:rolleyes:

Kind of like what maximus eluded to. In the "old days" guys either had a full boogie race car with race engine and hence full race cam. But when you had something bad, but not quite full race, you had a "3/4 race cam" Kind of a dumb saying when you think about it :rolleyes:

[Freak]

LOL I remember back in the 80's a Crane advertisement in Hot Rod mag for their 3/4 race cam. I always thought it was a hot street cam that would be mild on the track. Kinda the "pro street" grinds of today.

[Freak]

Results we need results from the big day!

[HEAVYBOAT]

What a crazy day, we had to get up at 3 am this morning and drive 4 hrs in heavy fog in order to be at the dyno for 8am.
Overall the day went pretty well, I had some problems (every pull) with it misfiring again at approx 6400rpm and up. And here I thought I addressed it with getting rid of the shitty crab style distributor cap, but I thought wrong. So now the only thing we can think of is it possibly snuffing out the flame(spark) at higher rpms. Maybe the plug choice was all wrong.
Ok, and the new BDS AIRLOC rotor blower has got me a little baffled. Dustin at whipple commented here a while back that the retro type rotors just "make more power at one rpms and less at another" emm...
This is the only way I can guess how my boost is higher at 4500rpm then it is at 6500rpm!!. That Tricky little discharge port can play games with ya cant it. .I'm going to have to start a new thread with this deal and hopefully get some answers. Anyways, the peak hp might not be as high as I wanted, (especially with not being able to rev it cause of the misfire going on) but not even in my wildest dreams did I expect this kind of low to mid range power. IT IS ABSOLUTELY INSANE!!
I need to scan some of these pulls to be able to illustrate this, so when I can get someone to scan them for me, I'll post them.

Full Race Cam = You were the baddest mofo in town. And the local speed shops best rear tire customer. No one but other full race status dudes would dare choose you off. Your car ran about 40% of the time... when something wasn't broken. You ran the loudest turbo muffers or glasspacks available at the time. Your parents garage looked like a scaled down wrecking yards engine parts room.
3/4 Race Cam = You were moderately fast but not yet full race status. You were an expert at water burnouts comin around the corners and across the neighbor you hateds front lawn. You were also a regular on Sat nights on Whittier Bl revving your 3/4 race cam small block in neutral at the stop lights. You broke a few axels dropping your Cast Iron Powerglide into gear at 3000 rpm. That was on nights you didn't blow the oring out of the torque converter and leave your ATF in a large puddle running from under your immobile car.
RV cam = You were a member or had at least submitted your application to the Good Sam Club and were the cheapest sob the guy at the Chevron station ever met in terms of the gas quality you'd always buy. Chevron Supreme was not your cup of tea and you used STP religeously for the better gas mileage Andy Granitelli had guaranteed you'd get on TV. You bought your STP at the swap meet along with your "seconds" OP shorts. You also had the latest spark enhancer installed on your coil tower and curb feelers installed on the passenger side of your car.

Sorry to hear it did not go well HEAVYBOAT. Starving the blower for air? Ask BDS for the airflow numbers and compare to carb size. Relief valve set too loose?
Easy fix --- Gear the car for 4,500 RPM ;)

[HEAVYBOAT]

Info, PM me your address so I can send the CANADIAN BEER, you wont believe how close your guess was. Unreal. Didnt you guess 1073?
1063.6 hp at 6403 rpm 9.5 psi
1010.1 ft pds at 4506 rpm
It was making 931ft pds at 2900rpm :eek:
Your lucky this slug was miss firing Info, the power was still climbing big time. You know... woulda coulda shoulda :wink:
Working on the video and dyno sheets.For now heres a few pics. Notice I dyno with the muffs, only the real deal for me baby!

The carbs are 1320cfm each, so hopefully thats not it. Thanks I will give it some thought. Could you expand more on the relief valve thinga mobober? Do they come loose? Ive never touched it. And whats your opinion on what plug design I should use? projected?

1060 hp 7 pds at 6400 rpm
Now,peak power?
I really dont know.... its gonna make some good power with 10 or 12 psi.
Lets wake up MR Moderator.
Info, lets bet a 12 pack of beer cans (shipping included)on whos closer.. most power I can make with a carbed 871 burning Gas.
This yr, Im going to run C12
I will disclose pulleys, combo ect
You in? :cool:
WOOO..... JUST WAIT A SECOND
My guess was 1060 hp and my pull was 1063..

[Infomaniac]

I was going to post earlier that I will not collect since I had specified 7k RPM and 12% under to get 7 PSI ;) ;) ;)
You overboosted HEAVYBOAT :rolleyes: LOL
Seriously man. I would look into why the oil pressure dropped 10 PSI. Did you guys cut the filter open?
Also on the relief valve thing. BDS usually recommends a dimension on the compressed length of the spring. It should not have lost boost at higher RPM. If anything it should increase.
I would think the misfire and boost is tied together.

[HEAVYBOAT]

Cut two filters open, all looked good.
We did do one hot lap pull, one after the other.. oil temps were up 25 or so degrees on that one pull, could that do it. I only see a 5 psi differance.
Rick

[Blown 472]

You put a blow off in that blue thunder intake? they dont come with one.

[Infomaniac]

Nevermind about the oil press thing. I had to enlarge the photo so my eyes could read it better.
looked like 63 to start and 53 at the end.
I would be happy with the results.
Did that manifold have a relief valve?

[Freak]

LAMO I remember that!

[HEAVYBOAT]

Yes it has a relief valve, and now that you mention it, I do remember the spring measurement. I'll go out right now and do it.
If it did open, you would think it would show a big boost drop on the data? no?

[Unchained]

When I ran a blower I got the whole setup from Hampton with a competition tall deck manifold. The manifold had no blow off valve.
I asked Don Hampton about it and he said if there was a popoff by the time it lifted the damage would already be done so he doesn't use them. He must know his stuff because he's been building blowers for decades and had the nitro funny car record for a while back in the 70's
I have a homemade popoff on the side of my intercooler box. I set the spring pressure with a fish scale which worked pretty good.
I also checked the fish scale with a barbell disc and it was pretty close.
I'm sure it would only help to vent excess boost or a spike on shutdown. If there was a serious backfire it would probably blow one of the 3" aluminum tubes off from the compressors.

That is who designed the blue thunder intake and he told me the exact same thing. Never had a problem with it.

What procharger are you using on that 434? I am interested in your combo,so could you list the perticulars please, camshaft ect. We are building my brother in laws procharger F1R this summer for his 52 chevy p/u. Its a mild 383 brodix deal. Is yours fuel injected or carbed?

What size injectors were you using?
What size throttle body???

[GEOO]

I was not planning on building that much boost/power. I was running a 5" Blower Pulley at 6lbs (738hp). I switched from a PC 324 IC to the larger 504 IC and wanted to try a smaller pulley . My 4.75" did not fit so. They had a 4.25" at the shop so we put it on. We tried a pull on the dyno and the dyno was set to low so we backed off. When I saw this I chanked up the fuel pressure from 60 to 75lbs, this made my little 55lbs Seimans feel like 72 lb per hour. The DC was 100% by 6700 rpm and got a little lean 12.5 A/F by 7000, approx 576lbs of fuel. This was the only pulley change I had while at the dyno. It was one quick pull. Waiting for larger injectors. I'm switching to a larger pulley 4.75" or 4.5" don't need that much power..
The TB is an old Cutler, like the new Holley, 1000cfm.
I'm going to run 72lbs @ 60 psi.
