1000 HP @ 7000 RPM Pontiac???
 
I'm sure there are a few.

Anyone willing to post a dyno sheet where the engine made 1000 HP @ 7000RPM?

Calvin,
Chris posted this a few years ago. Not exactly what you wanted.

I got 1052 @ 7000.

If you spend wisely and spend it with the right people it wouldn't be terribly hard to do.

Curt,
Do not know what the dyno correction factor was. But if the 5 column is fuel? You should have some very nice BSFC numbers what ever it was.

Mr Geise, you had a true 1000 hp at 7000 rpm but the other posted dyno sheets were close (not quite there at exactly 7000 rpm)
but made the 1000 hp a couple of hundred rpm higher. Close enough for me. Good job for all who posted their numbers.

A few here, all made well over 1000hp in upper rpm range

The main reason I brought this up, some guys have decided to move to the BBC combination. As we've seen over the past few years, 1000 HP is very attainable with the Pontiac engine, but not something that will come from tossing abunch of parts togther. My point is to build the engine for 1050-1100 HP which will require a well executed induction system, you can always gear the car to lower the RPMs throughout the run to increase longevity. All Pontiac engines are cylinder head challanged. The dyno sheets or combinations posted had a high end designed head, intake, cam and fuel system. These combos werent intened to peak at 7000 RPM, but much more. Raising peak torque is horse powers best friend, higher RPM's can be a killer on parts. The typical mind set in the Pontiac community is building torgue monsters and motors that don't redline above 6500 RPM.

Crazy old thinking!!!! You can turn 7500rpm all day every day without issues and no maintenance but for some reason Pontiac guys don't seem to want to believe that. I turn way more than that (cross line at 8600-8700) and haven't touch anything on mine in 3 years. I do check thinks like lash and valve springs but nothing has changed in 3 years.

Might not meet the RPM.... this is at the wheels.

Better photo, this is 10psi boost, 5710 RPM was max HP, 4865 was max torque.

All those yours ? The second one is very impressive. Was the top number peak HP ?

Tom Vaught 10-08-2017 09:49 AM

Dragncar, Richard is a very good Racer and competes every year in the Drag Week Event if possible. He is located in canada so he drives the car thousands of miles each year.

The Engine is a Luhn Performance Boosted Engine package.
1000HP/1000FTlbs at 5800RPM (drive it anywhere) package is very impressive.
Why I push Boost so hard. Easy on parts and easy to make the power with the right set of parts.
Luhn Performance has done a lot of boosted engines for people: California, Texas, Canada, that have been successful (Both blow thru carbed and EFI).

But a Boosted Engine like Richard's at lower rpm numbers can have outstanding durability where as a 8300 rpm engine (Trailer Queen) is obviously a different maint package.

Not as easy as you think finding the right people that is!

Don't know who's dyno sheets they are. But the left one sure looks like it is a cropped John Marcella's sheet from Barry's dyno (Survival Motorsports).
