So it is (21+14.7)/14.7 = 2.42. Now you use the 2.4 for the pressure ratio. To figure out hp you take the airflow and multiply it times 10. So if you where looking to find out if this turbo will work at 500 hp you take 50 on the bottom and go up till you get to 2.4 and see where it lands on the map. Which is right close to the middle of the map. Hope this helps, you can also plug in many different psi numbers instead of 21. like say (30=14.7)/14.7=3.04 which by looking at the compressor map this turbo will make 580-600 flywheel hp which is right on par with the guys making around 500 wheel hp at 30psi. If you figure in drivetrain loss from the flywheel to the ground the car will probably be around 409whp at 21psi. With a 22% drivetrain loss.
So 409whp wouldn't even be close to throwing 128mph in the 1/4. That's more like 119-120mph which is believable.

Both were performed right before my eyes at E-Town. Both happen to be mebers here. Ron, basically Turbo Trixx parts tester. He ran a 11.7 @118 with boltons/cams/AEM. Stock turbo and injectors. Thsi was done with 400WHP on pump.

The 10.8 was right before my eyes again, IDK what to tell you?

I believe both times. I think everybody does. I just question the fact that you say they where on pump gas. If they where, can you have them reply to this post?

If it is on pump gas was that with water/alcohol/methanol injection?

Stock Turbo.....400whp on pump gas....not going to say its impossible. I would just have to see it with my own eyes on stock turbo. I maxed the hell out of my stock turbo and made almost 400whp with it, but this was with race gas. I could see it being done on pump but you would need water injection/meth. But even with that you would not make as much power as seen with the race gas, so it too is hard to believe. Oh and on my stock turbo setup I was runing 11.80's at 118mph. So the 400whp figure is right, but if you were to slap a larger and more efficent turbo on there than you could probably push the pump gas figures even higher to around 440whp before needing some type of added injection. Being eighter water/methanol.... I know this for a fact because I have tuned a few evos with it. With the additional injection I was able to hit 490whp with pump gas... BUT this was not a stock turbo evo.

I am making 350 on pump, now add an AEM, and some bigger injectors and a 12/1 A/F and proper tuning, it has been done, a 11/7 @ 118 was accomplished on pump as well.

on 93 pump you will never be able to properly tune the car to 12:1. You also said that this guy was on stock injectors? I was maxing my injectors out when I was throwing 112mph on pump at 11.3 a/f, any leaner and the car would knock. BTW I was only running a max of 10 degrees timing(power fc).

My buddy and I are running the usual bolt ons with the AEM. Everything but a manifold, Upper intercooler pipe, and suctiond pipe. I am running a Hyperflow front mount and 720 cc injectors. He is running stock FMIC ans Stock injectors. I have hit 115 in the quarter and he just ran Wed. and ran a 12.001 @117, both these numbers are on race fuel w/ stock turbo, no porting or headwork. He is right there breathing on 11's. I have to get back to the track.

NOT STOCK injectors on the GT 35R, sorry my mistake there, my car runs an 11.7 On a flash, a 12.0 is FINE on a stand alone, its all int teh tuning, 400WHP pump gas is not unhead of, average with botons and cams/pullys/ is 380WHP, he has a runner for the 400WHP.

He was not talking about the GT35R he was talking about the stock turbo car.

c16 pump that is...

If you're referring to Buschur's 11.7@118. That was on RACEGAS, Amigo.
