thats an awesome curve..you got 400ft/lbs of torque by 4000rpms!! and is at full load before 4500rpms.

so I take it the GTX3076 spools pretty damn quick, wheres the top of the efficency for boost on this turbo?

Can we get some pics of ur car and engine bay?

Amazing car! That's some of the best spool I've ever seen out of an ATP 30R turbo. Any idea how much that specific set up may have added to the performance?

I think it is from the set up. Usually ported head works better at higher rpm.

Thank you guys, I don't know exactly but once I have that kit on a stock car, then I will know and will post it.

Subarocket......Love the look of your car.....I wouldn't mind building a RS for a track/weekend toy....

I am actually surprised you aren't shifting the car about 7500rpm based on the dyno plot you posted....

Gotta love AWD burnouts near the top of 3rd gear Especially on 275 R888 Told you that it would be plenty of power for that chassis.

BTW just to clarify for everyone else out there,the turbo is a T3 flanged 3076GTX. It is NOT an ATP bolt-on. The heads are Yimi Sport CNC ported and the rest of the car was nicely conceived and assembled by Renner Motorsport.

I'm guessing early tq is from light chassis. What's the weight of it? I have ~2700lbs rsti that made 350awtq by 3500rpm on safe tune with minor exhaust leak

Ya, you can see that just from looking at it. I'm actually surprised, nearly all of the ATP 30R set ups I've seen spool no where near that quick, hence my question, if the owner knows how much that specific set up may have added to the performance gains. They usually do great on the top end but suck down low.

The weigh of the chassis has zero bearing on dyno readings on a dynojet.
