Okay, I have pushed my small 16g to the limits. I am running 25 psi and it is making no difference in airflow whether I have it at 21 psi or 25. I think the wheel is just spinning at too many rpms. On the compressor map, at 25psi (pr 2.7), it is almost off the chart.
I am running e85 and tuning with ecmlink v3. I have already logged 35lbs/min with the small 16g. I ran a 12.27 @108 1.6 60ft (90* ambient temps) in my auto awd tsi at completely stock weight minus a crash bar. I am also running 22* peak timing. It didnt change at all from going from 19* up to 22* on this setup either. I ran 12.2 to 12.4 20 times in a row no matter changing boost, timing or afr. Afr was between 12.0 to 12.6 during changes.
When power braking my stock tranny with line pressure mod/shift box, i get about 3500rpms and the small 16g is at 25 psi when I launch and never drops all the way down (probably because of stock o2 housing, unported turbine housing and stock 2g mani unported.
Anyway, I need more power, plain and simple. I want to be in mid to low 11's or maybe 10's. I can lose weight in the car no problem. The engine is a stock 6 bolt rebuild which has performed great and 162psi compression across the board. So I cant go too extreme.
Also, I am not going to upgrade the stall anytime soon. At least in next year. So I have to be able to spool it pretty well at 3500 rpms.
I have thought about FP 68hta. Billet wheel, choke flow 47lbs/min, is running 10.1 @ over 130 in lucas's stock auto tranny dsm. But i feel the td05 housing is a big restriction and that I will be maxing it out soon too. And lucas english's car is a great setup so I dont feel like i will be near his times. But I can keep oil lines, intake, exhaust manifold (dsm flange td05) all the same with this turbo so its the cheapest way out.
Borg warner s256 extended tip. Rated at 300-550whp. I dont know if I would keep dsm flange or go t3. And I dont know which a/r would be best for spool and top end trade off (for t3 that is). It seems like this is the best bet to upgrade once and it supposedly spools real quick and give alot of power. Down sides are new manifold for t3, turbo costs more, need external gate, new o2 housings, new intake, speed density maybe, and oil lines redone.
Or should I do E3 (which I dont think will do much better than small 16g) which is cheapest route, or go big with a t3 35r kit (most expensive) Or maybe a precision turbo t3 5557 or 5857? But I dont know about spool with precision turbos. It seems the borg warner 256et is spooling quick and making power for similiar price.
Well I know this isnt a dsm board and all might not know these situations or care for that matter but I know gene is here and so is donniekak and STM.
