LOL. You're right, the top end is even better and the d@mn turbo is accessible.

With 15 PSI boost?

It's unbelievable or I change the psi to bar incorrect.
With stock exhaust and intake?

good, that's what i'm running so i was just curious if dual 2.25's would be ok. I know mathematically it is more surface area but sometimes things are weird on cars when it applies to physics.

Bryan, do you have a compressor map for this specific turbo?

Thank you Bryan. The kit as a whole must be very efficient to be making the power that it is given that airflow spec. Kudos.

AIT starts around 72degF and ends +25degF at ~97degF peak, 7000rpm, 15psi boost. Not bad. AFR is tuned sub-12 throughout.

on the first run or after it's been on the dyno for 2 hours?

That is on par with what Vas logged on 14psi with that 6" core FMIC, going from 1st throught top of 4th gear on the street.

not to thread jack but yesterday on my hurt motor mine was ambient at 59* and after doing a pull through 2 gears then another one shortly after i only went up to 86*. 17psi boost with a 6" tall core.

You can't accurately compare AIT increases Dyno vs Street...

you can't accurately compare AIT from the first pull on a cold engine to an engine that has ran on the dyno for 4 hours and is so heat soaked that you can't touch the plenum. So there is no accurate way to compare anything when it comes to ait's.
