Thanks everyone

Thanks, I'll update my first post with that chart too.

By the way, this is inspiring me as I'm working on a new project motor...
Hehe it's so easy to be tempted... I was actually only planning on 1.0 bar max but then I felt the need to break 500 rwhp
Hey Tom your engine is FAR to nice to replace with a new project!

Pump gas.

Duke your dyno is by far the most impressive I've seen. The power curve is amazing! You must be so pleased with your setup. In my opinion your dyno is now the one to beat. You've got over 3k full k of peak tq! Crazy man!
Thanks John, that really means a lot. I've spent what could be described as a fanastic amount of time on the engine/car and a fair share of money too. I'm truly happy right now to see that it paid off.
30k is not unreasonable if you have someone else do all the work and tuning. I would say I'm closer to 20k than 10k in parts and raw material alone.

Great results Duke and can't wait for the T shirt.
I brought U.S. to the car - Dynojet
Haha I thought I was the one getting a T-shirt!?!

Cannot share them all there's a lof of stuff in the setup that combined allows good power without knock: large displacement, good designed head, low backpressure turbo, large intercooler and a cool running engine, EMS for precision tuning etc.

Haha, i can tell by looking at it im guessing you've got a secret head work done. It's an awesome machine! You reckon you may PM me on the est price you've spend on the engine alone, if you don't mine that it

+1 Because you still retain the ability to add race gas and turn the boost up. he made these numbers on only 17psi. So some more octane and 22 psi?????

would be talking close to 600 at the wheels.

22 psi and E85 would definately be 600 rwhp.

Hit up that E85 or race gas and turn up the boost a little more.

But really this build is awesome. That is just crazy the torque. I can't believe it actually.

DUH - okay, thanks for that.

I was just getting ready to call BS on your 500 ftlbs tq at 3600rpm

Gustaf, Nice numbers. Keep up the good work! Why do they show Nm and HP. Wouldn't they show
NM and Killowatts or another "metric" HP measurement? Seems they are mixing SAE and Metric. 609 NM is 449 Ft Lbs. by our calculation. Is it just because you guys are used to NM just like we are used to Ft. Lbs? And HP is more a Internationally understood number?
