S257SX-E .78AR twin scroll

Post by R34SR »

Today was monumental for me... Been wanting 400whp for a long time but we all know how life goes. This morning after driving the car at 14 ish psi for a few weeks and feeling confident all systems were working I decided it's time for 18ish psi... Did about an hour of street tuning, and finally landed my number.... There is so much more left on the table with this turbo and build but after reading about the head lift issues other members faced after 400wtq...i think I'll just enjoy this for a while. Thanks to Nukeks14 for sharing his dyno thread, he is the reason I got this turbo and looks like our numbers are pretty darn identical for 18ish psi!... Pics suck ass,. I'll fix that later, just wanted to share!

I'll get a better graph eventually, that run was to 6800 rpm. But virtual dyno cut it off for some. Reason.

Thanks man, stupid alternator tensioner bolt backed out and lost my belt today during a very enjoyable drive.. Luckily I was able to get home before the batt died.... Yea the way the car feels right now its like it's begging me for 25 psi... But I'm fighting the urge.

25PSI sounds like a seriously fun party.

25PSI, sounds like 500+ whp time. Drag radials / 140 TW or lower for that.

I assume you're planning to run ethanol if youre going to push 25?

I run boostane, e85 isn't really an option for me... My car sits for months while away for work.
