not sure about this T3, T4, GTXX sizing stuff but for an S4 turbo the Primary scroll has an A/R of .4 and when both scrolls are open, they have a combined A/R of 1.00

Yeah well on a 30 degree c day, i ran a 13.5 on the stock turbo, had a 2.1 60ft and @106mph on 215 street tires. My cars putting out 167rwkw and 510nm i think thats about 225hp at the wheels. I think a much lower 13 or high 12 would be possible on a cooler day, the car really felt like it was suffeering from the heat.

Well,
With stock S4 turbo, Stock S4 turbo motor, 17PSI, meth injection, stock fuel control, disconnected map sensor, 720cc secondaries, a Walboro, on street tires, I ran a 13.1 @ 107 with a 2.0 60ft. My best trap of the day was 109.
The car had no passenger seat, rear sound dampening carpet thing, or speakers, oh and my skinny *** at only 120 Lbs.
I assume, with the proper driver, Better fuel control, and drag radials, or slicks, and some moderate weight reduction, a mid 12 is not impossible.
Keep in mind however, in the 2 day weekend I spent at the track, I destroyed my perfect turbo by running 17 psi.
For any nay-sayers, 17 psi was NOT maintained to redline, not even 6000rpm...

my TII's previous owner claimed he ran 12.6 s quarter mile on the stock turbo..
before i upgraded the turbo, i had it dyno'd and it made 249 whp on a dynomite dyno (reads similar to a mustang dyno). 3" exhaust, RA rebuild, 750cc/1000cc injectors, rtek 2.0, fmic, ported intake manifolds, tb mod, and stock turbo with boost dropping to 7 psi near redline

I made that exact same power with stock IC, SAFC, RE ECU, RB 3" race exhaust, 550/750cc inj, ported pineapple fresh rebuild. Stock TB and manifolds.
Fresh ported engines make SOOOO much difference. The proof is over flowing the stock turbo at 6-7 psi near redline.
Back when my friends FC had his stock turbo he ran 13.4@109. Stock ported motor with stock s4 turbo. Microtech, full exhaust, greddy fmic, 13psi. With a better launch(finally got a good launch and lost the clutch when he grabbed second) it would have been in the 12s.
