Hell just last week the hotside wasn't even finished. Apparently I need to speed up my work.

Damn man! You got that car together fast. Lmk when your ready to tune/dyno a car with half that power. Lol.


Cant wait to see it out next season!

Shit, I'm sorry guys - I didn't intentionally leave the dyno numbers out of the post. I just forgot.

I don't think I explained much, but it was leaning out - and leaning out pretty good at that. Near redline it would just drop down to 14:1 in nearly a few hundred RPM. Anyways, one of the people there told me it was spewing fuel vapor out of the power valve vent holes - which explains the wierd spike in AFR.

There were two problems - the power valve restrictor holes were too small, it was a bit more lean through the range with the given jetting, than I'd like to see.

Second, the PV appeared to be blowing closed and leaning out - the spike at the top of the RPM range.

I jetted it up just so I could make another pull and not pop the motor - on the spring it made 741 on 21 psi (Remember, this is an 82MM). I put 10psi on the gate and it made 749@28psi - it spun BAD on the rollers.

I never got what I'd call a FULL tune on it, but this turbo put out 920 RWHP before..

I'll take it back sooner or later, I have to revisit the power valve situation first. I'm trying some 'new' stuff as opposed to what I had before.

Sounds like a turbo car. Nice job Brooks, I'm sure the world is waiting on the numbers.
