508hp/365ft-lbs@18psi, 67mm gtx4294
I currently run a gt4094r so similar to the gtx4294r. Quality is great and the chra exchange Garrett offers is great. Toss a seal thru it and pay $500 for a new center section is awesome. But curious why a past s475 owner went this route rathe than s400sx route?
Good Numbers there. Very realistic too. Not like the rest. At least you know who ever is tuning for you is giving you fairly real dyno numbers there.
135mph+ on the power level you have now in the quarter mile.

^^^ nice to know rx72c.
And sk8world, I was gonna go with the 400sx, but really wanted a ball bearing and a billet turbo. The price is about $1000 more for that luxury. But so far for me its worth it. Next step is beef up the rear end and go racing. ;-)

time machines tuned the car... im not really sure but i know the funny part is that it was at a conservative level (lower than 11.0) which is because i daily drive my car everywhere (thus the T56 tranny)

agressive street port, microtech, 4x1600cc injectors, 3.5in exhaust, 2 step, & not to forget me & islander have the same turbo except i upgraded the wheel to an 80mm (standard gt42 wheel=72mm) from tial & it has a 1.00 hotside
& also Islander didnt put what type of port he has as well?
edit & its 19lbs not 17

I would say close to 20-21psi for that power level. Things dramatically change once your over 23-25psi. Look what ever makes you happy.
But Dyno figures annoy the hell out of me these days. Everybody wants a million killowats.
