I wasn't really sure what to except so I wanted to see if this seemed about right for this setup to everyone on here.

I would think it would push a little more with that size turbo. But that drivetrain is going to rob a lot, and sounds like a fairly safe tune so I'm sure your right where you should be.

Sounds good. Hope to see some good track results!! Ill bet you could add another 2lbs of boost run it all season and still not hurt it!
I'm working on a Gbody build myself this year with a 82' Regal Stock Bottom LQ9, Trickflow 220 heads, and cam N/A Build car weighs 2980lb with no driver. Hoping to see mid to low 10's

Just realized I was at 110mph @ 6000 rpm with 3.70 gear & 88" circumference tires on all my dyno pulls (high gear). That comes out to something near 19% slippage. prolly should have it tightened up a bit. That's gotta be causing some power loss.

I would think a little more power out of that Turbo compression combination but you may be pulling a lot of timing out.
For comparison my setup with an 8.9:1 CR pulled 600RWHP through a TH400 and 12 bolt at 10PSI. I know I'm blowing through the converter at around 23.5PSI and above but I don't know my slip at 10PSI.

well I maybe pushing my luck with my set up, but I want to see will it live! Got a new engine sitting on the stand. Got a completely stock LQ4, with 100xxx + miles, only thing I changed was the oil pan, oil pump, 60lb inject, LS6 cam&springs. 16 passes at 15lb boost, but timing is low 7.5-8.0. Getting HP to tune with, so I can turn up the timing. Also have a snow meth kit. Heads, and intake never been off.

The 3.70 should be ok, we only run 1/8 mile here (sucks ).
