Why did the HP peak so low? It seems that a bridge would make peak power at a higher RPM. Not hating at all just curious. I ended up with close to the same results but at a much higher RPM. Nice torque numbers as well

The stock ignition system is limiting it's ability to consistently fire at higher rpm's. With a good sequential ignition system the power should continue to climb as the revs increase, which should make even more power at the same boost level.

Sweet. I like how the power curve is so progressive and the torque is flat.

Nice power for only 24 psi. Damn those 42Rs, i need one. I'm wondering what kind of timing he was running on that Q16, but its cool if you want to keep that to yourself.

Really nice results. I like the torque curve.

You mentioned wastegate issues. Which wastegate are you using and what sort of issues are you having? Creep/spring control?

No secrets, bridgeported, clearanced and pinned, 2mm Atkins seals, stock e-shaft, and no AI. Tuning, and engine porting are two big variables. We are constantly tweaking things a little at a time to see what works. Tuning what we build gives use useful data, and we are constantly learning new stuff. We did a street ported engine and single turbo conversion a few months ago and it made 500rwhp on 93 octane with no AI, which was a first for us.

forcefed7,

Which turbo was used on the "500rwhp on 93 octane with no AI" motor?

Great numbers!
