Gtx3576R.

having the tune into the knock threshold area will result in more power

I'm just running a gt3576 but have it set up to come on very aggressively.. Stever will agree it's quite quick on the street tuned that way.

I do have sticky 275's on the rear. I would be silly with 245's.

So you find that quicker than a more linear tune? Mine hits 14 psi by 2300 rpm or so and first requires like half throttle and it will even spin the whole way through second when it's cold outside

Was thinking it might be quicker with boost coming in slower?

[Ralph Wiggum]

You still need to drive the car, obviously with it ramping up quick if you pin it, it'll be spin city. I let it build boost then open the throttle all the way.

I do tend to short shifted it as well which helps.

Agressive tune FTW - just learn to pedal it

How aggressive? 20psi at 2500-2600?

I'm going to give some invo's a try next and see how they go, if they hold on well then time for a more aggressive tune to make the most of the turbo lol

Wastegate lock pressure is set to 16lb on the EB2 so that should give you an idea of how it ramps up. I'd have to log it to answer your question correctly but it wouldn't be far off those figures.

Other than the borg warner options that nobody seems to talk about already, I just think the GTX76 is damn hard to beat for a point to point streeter.

At QR on Sunday, I barely lost a sprint. Nobody destroyed me. The only ones that were quicker came on a trailers.

Best thing though imo, is they drive so damn nice. Virtually no lag - power on tap instantly.

You'll never earn dyno bragging rights with one but you will win most sprints and...not kill the rest of the car in the process.

Fixed.

100% agree. My car goes tit for tat with a 430rwkw blown, cammed ss (manual though)

How'd you get so much boost out of the little turbo? Can it hit 20lb briefly and then drops away? and your motor can handle it cos it's built? I thought my 15 was about the most they could get out of it but maybe they just stopped it there to avoid breaking stuff..
