Very nice!
Is that still using the On3 turbo?
There's power to be had moving up to better albeit more expensive Precision unit for sure without upping the boost a ton.

yessir that's the same On3 BMF 7675 turbo.

If I was looking to pull everything out of this, sure there are a ton of things i could get more here or there.....turbo, cam, heads, etc.

I'm definitely content now. It would have been cool to make 20psi just to say i hit a number, but i'm happy with the numbers at 14psi.

I'm really limited on traction....my 275/40 Nitto NT05's dont stand a chance. One of the next things on my to do list is more meat. I have 18x10.5+22 wheels that i'm going to mount some 305.35 Nitto NT555R2. But they are too wide for the stock metal quarters. I've got a pair of fiberglass overfenders I need to install, but I want to drive this thing for a while.

I have an AEM 12 pot switch that i'm going to hook up to dial the boost back a bit for the time being.

If, big IF, I feel I need more power, i may look at some co2 or onboard air though I really dont want all the extra stuff.

@NoGo uses this on his six speed 900whp car and says it works excellent.
There's a post on here that talks a little bit about it.
RaceTCS = the Racelogic traction control equivalent - LS1TECH - Camaro and Firebird Forum Discussion
I was looking at something like this with my last manual turbo car but sold it before I ever got around to it.
Kinda wish I'd done it because the guy I sold the car to wadded it up in less than a month.

The RaceTCS does work great for keeping you on the road - dials in the traction better than the integrated aftermarket ECU's. I run it - a friend of mine runs it on his 1000 HP C5. It is a great system for dialing power down to exactly what the tire can put down. Highly recommended on anything that has traction issues.

You will spin any tire at that power level, but NT01's stick a lot better than NT05's. I have never been impressed with NT05's at all.

The NT05's were good for spirited driving, they'd get really greasy with just a little too much heat which I really didn't like.
I have the NT555 275/60/15 currently and they do much better, very decent on the street.
With a rolling burnout they at least get sticky and start to hook with a little throttle control.
Never ran the NT01's, they're for bigger diameter rims, I think?

I was actually pretty surprised the NT05's hooked pretty good at the 670whp range. may have just the pavement though.

I have NT555R's in 305/35/18 and they're incredible for street grip from a roll as well as have an awesomely predictable/transitionable grip limit, at a guesstimated 600-650rwhp.
