Going to the dyno...

[BrendellaJet]

How much power do you think it will make?
Chevrolet 548. Compression is pump gas friendly, but would be considered pushing the limits by some(Lets say 10.5:1 for conversation sake). Heads are Canfield CNC 330's with crane cams shaft rockers. Edelbrock Victor Junior ported at Wilson Manifolds. Holley HP 950, Basset Headers, MSD Digital 6 plus ignition & pro billet distributor. Solid roller with .700 lift, Olsen pan. Going with Pete Jackson noisy gear drive because I love the sound.
I know, #'s are vague, partially because I dont know them, others because Im paying someone for their professional services & knowledge & I dont feel like divulging any info that I have had to pay for. Plus, he'd probably hit me over the head if I did. Motor is being built by DNE.
I know what my goal is. Curious to see what everyone thinks it will do on the dyno. Supposed to go late this coming week.

[v-drive]

Well I think it's gonna pass a few. Just enjoy the boat you've worked so hard to have.......V-drive:D (aka) pop

I have started & erased a post three times.
First, I will agree a dyno is a decent tool for setting up a motor if you are running a jet. I have heard it is real good or selecting a scoop.
Second, Why does it matter what HP your motor makes. I would have more fun saying it makes maybe a little over 300 hp after you rip by the beach a little over a buck 10 or so.
It is almost like being a democrat, If you wan't to spout about the numbers your boat makes, you probably don't wan't to learn about what a dyno is really all about. Think about it.
Like said above. Get her running & enjoy it.
Gotta go, I'm out of nog.

[Cs19]

Not enough specs to make any educated guesses but Ill throw out 865 HP. Thats 1.58 hp per ci.

[MikeF]

858.......and yes, it's a guess. Should be pretty snappy with that carb.:)

[Morg]

Wait let me get desktop dyno running.
872

[BrendellaJet]

Hey, the boards are slow & I thought I could give people something to think about for 2 minutes. I definitely didn't post it so you could re-think your dyno rant 3 times over. ;) There is a nother thread for that.
Im going to the dyno cuz I spent a lot of money on this project and I want to see it get beat up on the dyno before I unleash my right foot on it!
:D 300 my ass. :D

Ok, Ok,

Good luck, hope it runs good.

600-650hp:)

[BOOGEYMAN]

758

[FILUCKY]

Got any flow #'s on your heads? I'm guessing that with a .700 lift cam that after valve lash and pushrod deflextion that you will actualy get about .650 lift on the valve. Your heads (just guessing)are most likily around 300CFM@.650 lift and that alone will not support 800+Hp, i would think that with a bigger cam and a 1250 Dominator you would see 800hp, but i'm not a chev guy so i'm most likely way off.:)

[BOOGEYMAN]

I said 758 just by going off of a buddies 540 build......he has a set of profiler heads 11.5 to 1 compression, more cam lift, a dominator and it makes 804 on 91 pump gas. It is a nitrous engine so the cam is not really optimal for an n/a appliction as well.

[396_WAYS_TO_SPIT]

Being that dave is building it Im going to say 865hp. Im building a similar motor but Im going with 13.5-1 compression. I would like to see your results as well just to get an idea:)

[396_WAYS_TO_SPIT]

We must remember that HBjet's motor made somewhere in the neighborhood of 700hp with a 496 pump gas mill and dave buit that one:idea:

[BrendellaJet]

I think these are the flow #'s...

Sorry, 700 was including lash. Its actually a little more but I dont know the exact figure.

[WannabeRacing]

Much is going to depend on the dyno session. If it is a week long session, you could really test things out and get close to a perfect set-up. Cam timing, lash, spark, different plugs, wires, other parts, carb work, different fuels, etc.
But in typical dyno sessions, a few variables are tried, and the numbers are what they are. I am guessing this will be more the second, so I will say 776 peak hp.
If it sat on the dyno and made 50+ pulls, I would guess more like 818.
But a 770 horse 540+ engine will kick the butt of 85% of the "thousand horsepower" engines running.

[FILUCKY]

Are ya sure your heads are 330's? Or are they 310's that have been cc'd to 330? i can't find any data on a 330, but i have found that there are a few CNC programs out there for the 350cc heads that will get ya 400cfm@.800. I can beleve that your motor has the 800hp potential with 400cfm but i still think it will take more cam (.830/.810-286/298) or so, and alot more carb. I think it sounds like a very stout piece but will suffer some from the cam and carb. But even as it is i'm sure it will run hard, good luck!:)

[UBFJ #454]

Among several things you can count on from a Dave Ebbert (DNE) motor is not suffering from a cam ... all the cams he uses are his well thought out design and machined to his exact specifications.

[steelcomp]

I think these are the flow #'s...
http://www.***boat.com/image_center/data/520/212bbc_flow_330.jpgNot hardly.

[FILUCKY]

I think the cam is most likely well thought out for a mild lake motor, not a race motor, just like the compresion and the carb, nothing against this build i think it will be a nice motor but it not set up as a race motor so why would it make race motor HP? Also heads don't flow the same numbers from .600 to .900 lift, it defies physics.;) I think these heads on a non-byis flow bench would most likely be in the 375-380CFM@.800, and that is still very respectible. Shops that build the motor, flow the heads and dyno the motor will most likely be byis to their own work and do what ever they can to make the numbers look maybe just a little better then they realy are.

[steelcomp]

What's "race motor" HP?

[FILUCKY]

Steelcomp, i would think that the hp guess's of mid to upper 800hp on a 548 with a single carb would qualify for a "race motor" not a lake motor. What did your race gas burn'n, big camed, canfield headed TR with two dominators make? 800hp or so? I understand that this has more cube's but that won't make up that much hp. mostly bring the peak hp in at a lower RPM.

[BrendellaJet]

Head flow #s are from CFE website. I questioned the intake #s from .600 on up, but it's what is there...
Just FYI, the lift #s on the cam are bigger than I wrote, I just dont know exact figures so I figured Id understate and see what people thought.
I know Im leaving power on the table witht the single 4, but with what I spent on porting that manifold It will be interesting to see the # it puts up.If I need a bigger carb I can always consider it.

[RiverRacer]

Looking at the flow chart you provided, 828 hp if everything else is good(it should be). RR

I understand that this has more cube's but that won't make up that much hp. mostly bring the peak hp in at a lower RPM.It has 80 more cubes, and at a conservative 1hp/ci. that's an easy 80 hp. You make my motor sound like some radical race motor. Hardly the case. My basically stock 310's flowed less than 350cfm, but with what I was building, I knew it didn't need any more air than that. My cam is way smaller than you'd expect, and my compression is 12.4:1...not very high at all for a "race" motor, which I really don't consider it to be. I'd have to do the calc's, but I don't think a 548 spinning 6500 needs any where near 400cfm. (I don't think a 330cc port is going to flow 400cfm, either, so that's a moot point)
Dave's got an excellent pump gas program going, and he'll get all the power out of the combination that he can, given the build constraints of the customer. If the heads are too big, there's only so much that can be done. If the customer is set on a single four, there's some limitation there. Dist. vs. crank trigger, oil pan choice, cam drive, etc. all add up, and also labor. How much detail work can be afforded? All limiting factors to HP. Jet boats are a funny deal when it comes to making usable power, and not many guys understand that like Dave. It's really not how much power you can make, but it's making it where it counts in a jet. Without any more info than has been offered, I'm not even going to guess, but I wouldn't call mid 800's near "race" power in this motor. Not coming from Dave.

[FILUCKY]

Brendellajet, i hope i didn't come across wrong about your motor build. I think your going to have a nice piece when your done, but i do think that you'll have a biger cam and a 1250 dominator in your future.:) I hope ya keep us posted on the build.

[BrendellaJet]

As for the bigger cam and carb, if the motor makes less than 800 on the dyno then I might change parts. I think a tunnel ram would be the next step for this motor and maybe some nitrous too. Im hoping this thing surprises us and puts up some better than expected #'s. Ill post some video when all is said & done.

[MikeF]

With the cooler weather......might have to make a revision. :)

[MACHINEHEAD]

Ill bite. Hey Mike F kind of like Todds huh. I won that $9 pool within 1hp. 785hp@6400 and 735ft/lbs @4800 if its 10.5 to one. Where do I claim my prizize.

[cyclone]

My prediction....the specs we are looking at are merely in the ballpark and not exactly what's ending up in the motor and this one, like the others he's built will one-up whatever came before it. so if you're privy to the power numbers of a similar combination from DNE then add 20hp or more to that number and you're probably in the ballpark because dave doesn't build the same combo twice. he's always trying something new to make more power.
that said, i have no clue what it'll make but i'm sure the carb will be what makes it run hard. lol
:D

Yep, they do seem to be close as far as the build......but Brian does insinuate that the compression is higher and the cam is also different then stated. They are testing on the same dyno, so that could be a decent gauge as to HP comparison between the two. :D

Brian started his build a little while ago so you will have to not compare it to Fuelinmyveins session. I'm sure w/ the extra carb it is a little easier to feed that engine.
Regardless, It will be a stout engine and wouldn't mind putting between the stringers in the Liberty.:crossx:

[cfm]

Did you get the BMF's or the Canfields CNC'd by another company ?
If you did get the BMF 330's then I feel you made a superb choice. Don't worry about if the published flow #'s match up with your benches #. They'll make some real good power. Flow #'s are one part of a long equation - don't put tons of emphasis on it.
Great choice on intakes - Wilson ported Vic Jr. Great bang for the $$$.
My only concern is the carb. It should work fine, but may choke off a handful of upper end power. A 2" spacer should bring some of that back, but not all of it.
Our your header dimensions up to the task of what this strong motor is going to require ?
Cool build up BTW !!! If your engine guy hit's the cam timing correctly you should have one hell of a motor.

Actually i wasn't comparing it to fuelinmyveins. i don't know much about his motor. just making a general statement is all.

[BOOGEYMAN]

So is this happening tomarrow of friday or????

[BrendellaJet]

Tentatively scheduled for Friday.

I know.:)
It's just the last 540 I saw come out of the shop was his......and I know Jordan had put some stuff in that Brian (I believe) has not.
Wish I had a 540.:o :D

The Dyno is a go, I talked to him just now. Dave called and said the motor is ready. Hot Boat has been blocked by Brian's IT department at work, so he can not post himself until he gets home. He is going to take a video camera with him to get some footage to post. Some impressive numbers are expected. I am absolutely amazed with the numbers they are talking about for a normally aspirated pump gas motor.

[cstraub]

I don't know what the target Peak RPM is for the mill but I would think with Dave's knowledge and ability and the combo it should be in the mid 800 range with torque in the high 600's.
Nice piece.

At least.:D
