GT1000 Twin Turbo: 934 rwhp @ 17 psi on 93 octane

[Hennessey Performance]

Don Goldman's GT1000 Twin Turbo made 934 rw hp and 816 rw torque at 17.0 psi boost in 60 deg. air. The SAE corrected power numbers were 877 rwhp and 766 rw tq. We found that at the 934 actual rw hp that the factory injectors were maxed out at 98%.

Don's GT1000 Twin Turbo will be at Barrett-Jackson in a few weeks. If you are in Scottsdale, we welcome you to check it out and we may give a few rides.

I will try to scan the dyno sheet later today (still moving my office). As you will see on the dyno sheet the powerband is of our GT1000 Twin Turbo system is very broad and has minimal lag at lower rpm's.

What size turbos?

 

[dbk]

Nice, hope to see it and possibly get a ride at B-J.

Dave, you can count on it. Cuda, they are GT35R's (T3). We use the same turbos on our TT Vipers and made 1030 rw hp on 15 psi and 93 octane a few weeks ago. There are a lot of turbos that are bigger and will make more power. But these smaller turbos have better throttle response on the GT in my opinion.

Thanks for the response, at what rpm do they come on? It seems like a good idea of yours to use smaller turbos to reduce lag. Look forward to the dyno sheet.

What type of base fuel pressure are u runnin and what is commanded fuel under boost at the top? Probally under 60lbs?

Nice numbers though.

Great numbers John!!!!

thanks Ray.

The lines cross at 5250 rpm, so I'm guessing 500ft/lb of tq is reached at around 3500 rpm. Not too laggy, and nice smooth tq increase after that, Looks good.

Can you post a graph vs RPM?

You can also take a screen shot on the winpep7 print preview screen, paste it into a photoshop type program, crop it, save it as a JPG, and then host it on the net somewhere.
