Current PB of 9.92 @ 139mph accomplished with 2.85/10%, ID1050X’s, C16, and PCM/TCM tune by Mike @ OST. Fast and simple. Car is full weight and then some including me at 230lbs, same as I drive it on the street with the exception of 315/50/17 ET Street R’s on RaceStars. Stock front wheels/tires, full interior, subwoofers still in trunk - the whole nine yards.

Last round of updates include new OEM bypass valve (original was bleeding boost above 6000rpm), FI blower spacer plates and 2.65 pulley ring. Hoping for a 9.7x at full race weight if we can get some boost weather and decent prep. Then *maybe* I’ll try front skinnies and remove the seats to see how much more we can get.

HUGE shoutout to Mike and Micah at OST - they’ve been awesome, getting me tune revisions after each track day and most recently giving me tips to bleed the air out of my intercooler before I yanked the damn pump off and launched it into orbit LOL. Really great guys who always make the time - thanks guys!!

Hoping to hit the track Fri night if we can keep the rain away - fingers crossed.

Paul...

I agree 100%. OST dyno is a fantastic shop to deal with and Mike knows his stuff.
Congrats on your new PB

Did changing the bypass fix the bleeding boost problem. I’m bleeding boost boost from about 5600 -6500. Losing 1.5 psi. No signs of belt slip

Will test it out as soon as I get to the track. If you’re logging with HPTuners, you can watch the voltage on the BPV - mine was dropping from 4.47v (fully closed) to 4.1x-4.2x from 6000rpm on up.

Launch on that pass was around 1500rpm.
