CrazyHorse where are the results???
 

we dyno pulled SuperV's motor today at Tom Earharts.......all went great ,the numbers looked awsome and I would post them but Crazy took the sheet! Dave get off the couch and post them will ya?????

As Dyno said, SuperV had one of his fresh 454's dyno'd at Earhart Engineering. Thanks go to Tom Earhart for taking time on a beautiful Saturday to do this for us.

All marine accessories and pumps were in place and operating during the runs including the stock flame arrestor, and per Tom Earhart's info, the dyno headers used perform very similar to the Lightning headers on the boat. A last pull was made without the flame arrestor to see if there was any difference in performance. Horsepower was EXACTLY THE SAME with the stock flame arrestor removed.

It should be added that we didn't run just a blank carb for the last pull, we installed (duct tape eh?? LOL!!) a velocity stack. Cool looking piece, but no help!!! The motor looked faster though.:cool:

Yeah, well, the point to the flame arrestor thing is that it don't necessarily gotta look cool to do an ok job. It was chrome though, wasn't it?

I'm tellin ya, chrome adds 5 mph at least!!!!!!!

Yeah, but if no one can see it does the chrome really make it faster? Kinda like the tree that falls when no one sees it. Does it make noise if no one hears it? Drugs, where'd I put my drugs?

Thanks for all the hard work Crazyhorse Dyno Waterfoul Kaama.That dog hunts!

Yeah, it ran ok. It was cool. That sucker pulls hard in the midrange, doesn't it?

It should be a grin!

It should be a grin!

Super V, are you becoming a post whore?

What are the specs of the motor? Cam, heads, carb and intake. Just so that others can have an idea of what gets you what.

Did you try different timing? What happened to the EGT's with the timing changes?

Specs are;
454+.030 GEN V, align-honed, paralelled deck surfaces
L2465 TRW pistons 9.6:1, Federal Mogul E-233K+.030 rings
cast crank with stock rods-3/8 ARP rod bolts
Merlin oval port heads, Fed. Mog. 2.19 intake, 1.88 exhaust valves
Federal Mogul VS1581 valve springs, 105 lbs closed, 310 open
dual-plane intake, Holley 800 carb, 75 pri., 89 sec. jets
Federal Mogul CS1140R cam, 234/244 [email protected], .553/.578 lift
Federal Mogul HT817 hydraulic lifters
Federal Mogul- 4400-.010 main brgs, 3190CP-.010 rod brgs
Fed. Mog. 1404 cam brgs
Federal Mogul gasket set #260-1009
Federal Mogul timing chain set #KT3-171S
Oil pumps were not replaced. Disassembled and clearanced.
Cam was installed at "0" advance
Rotating assembly was balanced
Main brg. clearances are 1-2-3-4, .002. #5, .003
Rod brg. clearance is .0025
Initial timing, 15 degrees, total advance 32 degrees
At Tom Earhart's suggestion, no timing changes were made.
KAAMA was watching the EGT's and oil pressures during all the runs and EGT's were always below 1400, oil pressures during the pulls were 65-70
Thanks go to Tom Earhart for the great time had by all of us at his shop, and to Gary and Sheryl Garvelink at G&G Performance Engines for the great machine work.
Dyno's engines are almost identical to this, the only difference being Federal Mogul hypereutectic pistons, #H693CP+.030, 9.5:1

Hey that sounds like an overall great experience for you guys.. Build it and run it and great numbers and a bunch of guys enjoying the sound of Torque and Horsepower..
Good job to all that were involved!!
Next we want to hear about the boating experience!! I am still dreaming about that!!


Dick

Looks good. Thanks for all the info :D:D

Great number's for 330's on steroids !!!!now we know I can pick up a little on my jetting.....cant wait for the new paint to be finished so we can get out and do some speed runs. The motor's will go back in SuperV's boat this week then look out Lake Mack here we come!!!

That will be the real test. It'll be interesting to see how the boat performs compared to the previous speeds with the old engine setup.

I like that torque staying at 500 or a bit more starting at 3000 and going to 5000 that should set you back in your seat, when is the first water test?.....Fred

Bill I just might be.Fred it should have tons of midrange!

Wade what props are you running?....may have to re-prop it so it tops out at 5000-5100 rpm's.....keeping in that torque range....Fred

Fred 25p mirage 3 blade 5600 rpm with old motors.Will need to bring it down a bit.

Great numbers guys!! Sounds like another great Double D buildup. SuperV, you must be pumped!!

Over the years I've had very good luck with the Federal Mogul parts and they are very reasonably priced. Dyno and SuperV, as well as Waterfoul and BGIII can attest to that. I think BGIII spent $440 for hypereutectic pistons, cam, lifters, timing chain, rod, main, and cam bearings, rings, gaskets, 2.25 intake valves, 1.88 exhaust valves, and brass core plugs. Federal Mogul also offers the 3/4 grooved hardened bearing sets for severe duty.

Similar specs to my 454 - bottom end is almost identical. I am running a milder cam - Comp Cams 236/226 .550/.540 I think. Was there any work done to the heads, or are they box-stock? Can that cam profile be run in combo with silent choice without reversion concerns? Might be looking for a set of Merlin ovals down the road a bit.

Nice Set-up Dyno
 

Dyno,
If you don't mind my asking what kinda $$$
Did you have into it redoing it.

Last night I was talking with a friend that has some tired 330's in a 32' AERO.

He would like new engines, I recommended rebuilding what he has instead of buying all new componets.

Anyways I said I would try to help him if I can with his project. So I'm trying to keep it lean on the dollar side for him as well. If you can say that in the boating world.

Thanks

Cougarman

Cougar man the entire package depends on what parts he has now.... I started with stock 330's rebuild the bottom end was around $500 in parts plus machining I dont remember exactly the ammount but I think with the bore it was $700 give or take. The heads Merlin ovals are around $1100 a set ,Rpm intake is $175 if you need a 800 holley you can find them on the board used I bought one on Ebay for $200 I put on MSD ignitions but you can get by with stock...The dyno pulls were done with tubular headers a set of Lightnings are about $1500. Thats a little under $4000. per motor with new exhaust.....You can get buy a little cheaper on exhaust if you buy Emi. manifolds around $1000. but you lose around 30hp....let us know if you need anything else..
Don

Budman I run mine through Silent Coice no problems to date....and SuperV's heads were pocket ported but not very much.....

The cam you describe is very similar to the cam Waterfoul and BGIII are going to run, Fed Mog #CS1139R, 224/[email protected], .527/.553. Desktop Dyno projects 421 hp @5000, 486 torque@4000 with 8.6:1 comp. ratio. At 9.5:1 c/r the numbers jump to 441hp@ 5000, 505 torque@4000. These numbers should be on the conservative side depending on your cylinder heads. A word to the wise though. The parts aren't the costly end of a job like this. The machine work is the expensive part. And the guy HAS to be good at what he does. Team Chaos has found a couple of machine shops that really take pride in their work.

Lightnings with silent choice?
 

Dyno,

Just curious about your silent choice setup. Are you running the lightnings into it? I'd like to see a shot of your setup if you have one sometime.

I thought Waterfoul was running the larger cam, like in Dyno's boat. Is he switching back to the milder one? BTW, I got the exhaust and intake numbers transposed for that cam, if you didn't already figure that out. :rolleyes:

Cougarman,

Very sorry to hear about your friend's loss. Condolences to him and his family.

Waterfoul had the CS1140 cam last year but we decided to use the slightly smaller CS1139 this year to provide more low and midrange torque. His c/r is a point lower than Dyno and SuperV so this cam should offset the c/r difference.

Crazyhorse,
The specs for the CS1139 is the exact cam my builder suggested and installed in my motor. Your desktop dyno numbers just confirmed EXACTLY what he said it would be for RPM and HP. However, his claim on the torque side was around 450 ft.lbs. Would an exhaust valve size of 1.72 as opposed to 1.88 have a decreasing affect on the torque numbers? If yes that would explain the lower number. By the way my C.R is 9.7:1.

Paul

I'd have to guess that the 1.72 exhaust is going to reduce the torque somewhat, but even running the smaller valve size through the desktop dyno shows about 480 for torque. It's also possible that your engine guy is planning on setting the cam up on a different intake centerline angle. That would also account for the difference. Of course it's always possible my 29 dollar version of DT is a little off.

Budman I run EMI manifolds with my silent choice.....I did have a set of Lightnings in my Checkmate that I ran through silent choice though....SuperV runs lightnings with teague switchable mufflers ,if I was going to do it again I would go that route....

Thanks dyno
 

Dyno,

Thanks for your help and input, I will be talking to him this weekend. Looks like this would be a really good way for him to go.

Thanks again

Cougarman

Whether he goes with the Lightnings or the EMI, I'm sure he'll be more than happy with the results. Dyno's boat really came to life with the engine and EMI exhaust upgrades, and SuperV should have a good running package with his freshened engines.
