LVjetboy's Motor Dyno'd today.... Any guesses?

[HBjet]

LV, I've been wondering all day today how the motor did, and how it did on that other octane! If you don't want to post the numbers (we all would know why) then shoot me a PM.
My guess is 812hp on that other octane!
HBjet

[Blown 472]

specs???, octane??

[MikeF]

Just a guess......875+. smile_sp

[OMEGA_BUBBLE_JET]

2800 hp 110 octane gas normally aspirated. Westech dyno.

i do not remember the C.I. or the intake set up,but from what i remember about his motor im guessing 790 just for fun. I was just checking out westechs website, its pretty cool.

[superdave013]

what's all this about HP?? Is it the Hp that matters or is it the toruqe?? :confused:

[HBjet]

If I remember correctly, it's a 540ci motor, with Profiler Alum. Heads and a tunnel ram setup.
As for octane, well, I know they where going to start with 91. From there I'll let LV tell what other octane they where going to use for the rest of the day.

is it a bolt on item? :p

[UBFJ #454]

Between 1,025 and 1,100 Hp on C-16.

[UBFJ #454]

Pro-Filer heads were quite different than Schmidt heads until Schmidt made a deal with Ray Franks (who owns and manufactures Pro-Filers) to sell the Pro-filers with some minor mods and Schmidt's name on them. You get a far better pair of heads buying directly from Ray Franks Engineering (QA/QC and special mods).
Pro-Filers are 12 degree, spread port heads.

These are standard port and are not the big chief or big duke style,they are just another 24 degree aluminum head.

[UBFJ #454]

edge -
What makes you think LV went with these heads?
Given who I've been told is building the engine, I'd be suprised if he did ... but ... you could well be right. If, in fact, he has gone with the 24 degree heads, you can be assured that they are setup quite differently than the Pro-Filer spec.'s you posted.
Having checked them out in detail and having a set of 12 degree spread port heads on our Big n2o motor, I feel Ray Frank's foundry process is far superior to Dart's and AFR's in terms of specialty ordering design of any of their heads and their QA/QC.

[565edge]

I'm just assuming those are the heads he used,I think he was on a budget?Those 12 degree heads are bad ass,I saw a set of the 24 degree heads and they were nice but one head was in three pieces :confused: ,I thought i was seeing things,He had a little explosion.I think they are a great re-placement head with alot of area to work with.

[ChetCapoli]

I dont know what kind of budget your on to have that shop build you a motor but god bless him. HE SHOULD GO FAST AND MAKE ALOT OF POWER. Big $$$$$$ is what it comes down to.
I'm sure it's around 842hp at 5500rpm on pump gas or some rediculous RPM that's close. As i have said, ONLY IN CALIFORNIA!
CHET

[UBFJ #454]

edge -
We cracked one of the earlier heads on the dyno ... radius wrong on # 7, so I know what you mean. Since, have gotten everything straightened out and we're now running "gen III's" with no problems ... nightmare for everyone, but it happens sometimes when your help "birth" something new.
While I would hope LV's on a budget, I do know how one can get caught up in building something different ... would do it again ... Hell, am doing it again with the Capsule TF'er ... Just a different way ... much slower, and more selective ... including doing much more myself now that I'm catching up with technology and retieing with old hands and meeting/evaluating new up and comers who are really good.
I really do hope LV hasn't broken the budget too much, only a "little bit".

[LakesOnly]

I like Ray Franks's work...
LO

[565edge]

Ray frank does know there shit!They are building aluminum ford big block heads too,Have any of you seen there tunnelrams they sell and you weld it,any pics of the kit?
Race Winning Performance out of the box...
We know how important it is to match an intake manifold to a cylinder head, and sometimes the on-the-shelf manifolds just don't get the job done, so we have invented the "Pro-Filer" welding kit to profice you with a cast manifold that meets your needs.
Our Welding Kit comes with 8 runner tubes, a plenum, 2 base plates, 2 china rails, floor pans (parts can also be ordered seperately). All you do is cut the parts to your desired length, match them to your port location, then weld them to the plenum and base plate. A cast manifold made perfect for your engine!
Technical Data
Tube ID and Length - .750" radius I.D. on runner tube corners on the rectange end and transend to a 3" diameter on the round end. Tubes are 4.750" long (cut to desired length)
Base & Rails - Base comes without port opening. We can supply you with the port opening upon request. Rails can be cut to your desited length.

Just got back. Geez that's a long boring drive. Turned respectable numbers on pump gas...yes...89 octane from the corner station. But not as high as I was hoping. I wanted to snap a picture of him pumping it into the jug but I was busy wiring a knock sensor. Dave'd dropped the c/r down to 9.8:1 after I reminded him it's gotta run not only 91 pump gas but crappy 89 "dock" gas. Don't worry, I'll fill in all the details. You'll probably have more numbers than you ever wanted. :)
BTW, I'm thinking dyno runs are only fun when it's not your engine.
jer

[UBFJ #454]

Revised est. due to 89 octane, 9.8:1 compression and not knowing carb setup ..... 795 to 885 Hp. Quite enough for a safe, reliable river "racer" jet.

w/air stacks and open headers:
Uncorrected:
684 @ 6000
STP Corrected:
766 @ 6000
Air temps about 90 and very high humidity.
Not bad for 89 Octane, but 34 hp short of what I'd hoped for. So I think RevnDave with his guess of 750 wins my old valve covers :) I'm sure Dave could've squeezed more but I'm like, "Do you really have to abuse my engine with yet another pull?" He say's no problem, changed ram spacers and gained 10 hp...looking for more. Better to have it break on the dyno than on the lake? I'm thinking ya right, sweating in the control room trying to stay calm. Meanwhile Steve's brainstorming with Dave and smiling at my stupid questions, answering them anyway.
At this point, I'm thinking hydraulics may've been a bad trade-off. But for c/r, I like the low octane peace of mind. I don't have charts yet, or an estimate of typical Lake Mead corrected numbers, but my (revised) best guess for speed according to JPC is 96-98 @ 5800. Maybe 100 if I'm lucky?

From what I can see from the pic.'s ... seeing the parts which make up the whole, I think you did a very good job of thinking this out and coming up with an excellent piece for how you intend to use it.

jer, congrats on the new piece! although it's kinda conservative for my taste, the tripledog dare is still in effect wink once you have the hardware set up for the new power, i have no doubt you'll see triple digits, if ya really want to go there.
and, if you ever want to get serious with it, it'll be easy to make some massive power.

good choice LV, I came real close to building the same head,intake combo as you did, but I was going with higher compresion and race gas, instead I decieded to go with the blower on pump gas deal. I had a chance to talk to ray franks last year at sonoma, he was helping a few guy's in pro stock that were on the steve schmidt motor lease program.

jer Cool lv, that is a nice set up and something you can fuel up on the water, good for you.
Thanks for being man enough to post your uncorrected numbers.

HBjet Dunno, you tell me. It just shows that lv doesn't play games like a little boy, cut a little close to the bone??

Blown 472:
play gamesOk... That's right, I'm playing games.
So is every other engine builder or mfg who lists HP numbers for any type of motor when they don't also list the measured numbers. Your right Blown, you win!

HBjet :D Having trouble quoting the whole thing???
When you were asked about your uncorrected numbers it took you two weeks to post them, I dont see how that has anything to do with any other engine builders, do you??

The point I'm making is the measured numbers aren't the numbers that are posted with every other engine builder. When you buy a car and they say it makes 250hp, your probably the guy who wants to see the HP at the wheels, and you want to see it measured, not corrected before you talk about a price right?
90% of the reason I didn't post them up is because YOU where so hung up on getting them! It was fun to watch you getting frustrated because you didn't have the measured numbers. I'm sure glad I didn't wait any longer, you might have busted a vein.

HBjet uh.....okay. I bet they wish they could use the measured numbers. car manufacters corrected numbers are lower due to drag of A/C compressors, altenators, water pumps, air pumps, power steering pumps etc. But you knew that right HB. I guess they should use the highest number possible. I for one think they should have to rate hp at the rear tires. the cadillac northstar was quite a surprise. 300hp at the flywheel and 180hp +/- to the wheels. kinda reminds me of a certain situation where a guy couldn't spin the rpm's he was supposed to. hmmmmmmmmmm

[DogHouse]

Even if the car manufacturers did use rear wheel hp, that would be fine, but they would STILL have to use a CORRECTED number for some standardized atmospheric condition or your comparison shopping would be WORTHLESS!!! Why is that so f'n hard to understand??? :rolleyes:

If I am buying a truck hp is not important to me. payload/towing capacity is. style is a big one. ground clearance, etc. not hp though. When buying a sports car I don't look for the biggest hp numbers. I look for 0-60 times, quarter mile times. skid pad readings, stopping distances. Are we seeing a pattern???? wink

HBjet don't go and get all offended on me HB. We all know your boat rocks!!!! :D I think 5800 is great. But not where it lines up on the pump chart. I think you should be around 6,000 myself.

OMEGA_BUBBLE_JET:
I think you should be around 6,000 myself.I would like to see it there too, and when I get another impeller, we are going to cut it to a B- or BC.

HBjet well judging from the dyno and the impeller you have now I would think that it could get to 6,000rpm now. Like I said this is just my thoughts.

Omega And this is from the JPC which isn't 100%, and an extremely tight pump, and a Legend impeller with a curve that doesn't match the one on the JPC.
Based upon that, I would say it would be hard to make an opinion and stick to it with so many variables and unknowns!
Just my thoughts!

[Dave C]

torque not important to jet boats???...... not that HP is unimportant though.
Anyone every try to advance and retard the cam and see what happens? (this is a rhetorical question?)

[DogHouse]

Jer, what kind of torque curve did you end up with? Corrected numbers, please, if ya don't mind... :D

Anyone every try to advance and retard the cam and see what happens? (this is a rhetorical question?) yes. last time on the dyno. it tended to move the peak and curve around a bit, but made little effect on the overall numbers.

how bout some more pics lvjet? i love all these pics. :)

[LVjetboy]

Well, since you ask,
More power means more pump pressure so found a regulator and made a bracket to mount...
http://users.lvcm.com/lvjetboy/WaterPressureRegulator.gif
On to fuel. More power means more fuel flow so ditched the electrics for mechanical and -8 to fuel pressure regulator. Need to mount about here...
http://users.lvcm.com/lvjetboy/FuelPressureRegulator.gif
Oops. Rex Tower's too tall, not enough clearance, gotta go. Need to make another bracket...done...
http://users.lvcm.com/lvjetboy/FuelPressureRegulatorMount1.gif
Symmetry's a good thing...
http://users.lvcm.com/lvjetboy/FuelPressureRegulatorMount2.gif
Oh no! Swapped bowls to get fuel lines down the center and guess what? They run into the throttle linkage! Figures...
http://users.lvcm.com/lvjetboy/ThrottleLinkageProblem.gif
Oh well, back to the work bench for new throttle brackets...
http://users.lvcm.com/lvjetboy/ThrottleLinkageSolved.gif
Need to clear NOS lines too. That should do it. Oh wait. Why does the aft carb bind just before secondaries open? Looks like Demon's quality control on the secondary linkage leaves something to be desired. Not only that but the secondaries on the aft carb open later than the forward carb. Shit...
http://users.lvcm.com/lvjetboy/SecondaryLinkageProblem.gif
Sorry ass linkage on the left is theirs, my mod on the right.
To be continued...

Continued...
This's getting old. No C3B for me. Haven't even started electrical. Oh well, cut some new linkages with SS pins and force fit for a more accurate secondary opening. No binding and synchronized opening...
http://users.lvcm.com/lvjetboy/SecondaryLinkageSolved.gif
Much more precise. Just the usual rigging hassles. How's that for a few pictures?

[UBFJ #454]

Just wanted to bring the thread back up to the top so LV woudn't forget to keep posting info.

[flat broke]

What gives Jer, dodging out on our event again eh?
I'm just messing with ya. The mill is looking great and your attention to detail is awesome. Keep up the good work and I'll either see you on Powell next year, or at the CBBB.
Chris

[LVjetboy]

Bear, I'll be happy to post when I have more details and pictures. Tryin' to limit net time somewhat...need more garage time!
Chris, looks like it. Haven't cancelled AVI yet, but with less than a week, not sure how it'll ready in time. I may have a leaking left gas tank, gotta check that too. :( And I need at least one lake test before putting it in the river. Crimp-on electrics and hose clamps not an option. We do have a couple trips to Powell planned...September and maybe even later this year?
jer

[565edge]

Looks good,Where did you get those tapered carb spacers?

[LVjetboy]

Dave cut those to 4 degrees on his incredible milling machine. They're pretty cool but tapered spacers instead of a tapered ram makes the velocity stacks uneven.
jer

[Squirtcha?]

Lookin great LV (not that I expected anything less). It's gonna be a bummer if ya don't make it, but I'm hip to the rigging hassles. For a while there, I actually thought we were gonna end up in the same place.........at the same time. If'n ya don't make it, we'll have to see if we can put a run together yet before summer's end.
I kinda like the staggered velocity stacks. It gives it some character. If ya don't like it, maybe you could remove some material off the bottom of the stack to compensate? Seems to me there's some extra there to play with?
[ August 03, 2003, 12:05 PM: Message edited by: Squirtcha? ]

[svtrich]

what kinda torque numbers did you get and what intake are you useing? your motor sure looks great!
Richard

[LVjetboy]

Did anyone see Kevin Harvick's victory burnout at the Brickyard 400? Rpm's thru the roof 'til the rear tires melted and exploded...blew the back end off the car. I'm thinking yea! What kinda hp does that? Oh wait, the same kinda hp that's sittin in my little jet boat right now. Only the jet runs a tad less octane. 89 vs 110?
:)
Svtrich, thanks. Intake is RFE (Ray Franks Enterprises) and torque? STP 737 ft-lbs @ 5100 rpm. Not that I care about peak torque. Net power delivered to the impeller determines performance in my opinion.
Squirtcha, thought about both cutting or adding a spacer. I'll probably just run the stacks the way they are for now. Busy grinding slip-in Bassett "performance" mufflers so they really are "slip-in" ...and "slip-out" Burned the h*ll outta my hand before deciding that gloves and grinding are a good thing...

I'd like to meet with you AZ guys this year if it's the last thing I do...
