Me vs friend. At the time I was still diagnosing the traction issue/lane changing, so I had to let off as it spun tires in higher gears

Not the Best quality vids, but we are both coming out swinging come race season again

 

Well damn you for having APR mirrors that stay put. My car making 230whp would make them fall after hitting 80 mph

 

oh no, they dont stay put at all. They were the first thing i sold and replaced with oem. camera car had them and seemed to be fine though

 

I didn't realize the 6262 could net 700hp!

 

My old 6262 put down 741 whp at 29.6 psi on a dynojet and around 800 whp at 34 psi.

 

For sure, I made 730@27 psi but it wouldnt flow anymore, even at 99% DC

 

There must have been something going on with back pressure or something. You could have gotten a lot more than that out of it.

 

Possibly, im thinking its the exhaust. 3" dp but 2.75 T1R back. ive got the 6466 now, so we shall see, contemplating just doing a boost activated valve as I like the mildness and tone the T1R has

Or do you think its something else?

 

Yeah, that exhaust chocking down some like that could most definitely have been part of it but there could have been other factors too like manifold design, turbine housing, etc. I am on a full 3" exhaust. What ar was your turbine housing? I was on a t3 .82 at the time. Am also running the 6466 now but this time I'm going divided t4 with a 1.15 ar, which I'm still wondering if that'll be big enough for the top end.
