What's funny about that Dyno session too is that we drove the car through almost 90 minutes of Houston traffic to get to FWD from MPx, and it only sat about 10-15 minutes before pulling it onto the Dyno. No trailer/Dyno queen here!

Running the 275/35/18 Hankook RS3 we are able to handle a lot of that power, but my boost box really keeps it in check until I get into the higher gears...

This is my street and track tune. No changes needed... other than common sense when on the street.

The Garrett engineer told me the same about the boost level. Still on 3 bars for now and no real need to turn it up anyway.

It's not what the GTX says... Each turbo is 1 step up from the last. Just looks at Douge GTX3071 Hp.

Thanks for the welcome back.

I'll have to look around and see what people are doing number wise with billet 76's..
3576 would be a 35r turbine wheel with a 3076's compressor wheel in traditional terms.

FP rates their HTA3076 at 59lb/min. Now that I look at it, their inducer is 54.8mm. The GTX3076 is a 57mm...so rating is probably in the neighborhood of mid 61-63lb.
With the larger 35r turbine, might be able to eek out an extra few hp to boost that # up.


You may be right, and maybe it'll do 750...but my guess is the stars would have to align, run bookoo boost, and have perfect conditions, lol.

Either way, I'm sure it'd be a bad ass turbo.

Pumpking.

I'd have to agree with this.

That's unbelievable power out of that turbo.

A GTX3076 is around a 65 lb/min turbo, flows about the same as a plane jane GT3582R. Combine it with a 68mm turbine wheel I don't think a GTX3576R will do 750 either. It is a sweet turbo however!

There is people taking the Gt3582-86r way past 750hp just look into it. The GTX 3576r will make 750hp with the right setup and tune, plus will hit full boost @4k. I think it would be a great match turbo for our car. Bump the rev limits to 7+k and you would have a nice powerband. The GTX3076r doesn't do so well so this 3576 is the fix others are talking about. Just going off what I have read so far.
The GTX lineup seems to be the real deal quick spool and big power!

I've seen lot of guys do 750 with the HTA82. The folks doing the 800+ are rocking the larger exducer'd hta86. That's just what I've seen on evom though. I don't go to many other forums these days.

You plan on going gtx3576, sean? It'd be cool to check it out in person once it'd be on and sorted out.

I don't know about way past? I've seen a few above 700. Got any links? I'm more going off of what we've done and I've seen.

Here's my GTX3582R at 32 psi and e98. Believe me, I'm a huge Garrett GTX fan. We put a GTX3576R on a subie and it felt great but it's on a stock motor and not running much boost. But it's still a 58mm turbo, 750 out of a 58mm is a little crazy imo.

Thank you sir! Yeah this is on a bugeye wrx. I have some restrictions like a small throttle body and I think a small header/uppipe and we are over a mile high in thin air so the turbo was just blowing steam after ~32 psi.

This new GTX3576r is a old hta3582r and should make the same power.

I'm not ready to make the jump yet, but I am looking into this GTX3576r a lot.
Very impressed by Dougs GTX3071r with 600+hp@26psi with a .63ar.
A GTX3576r in a .82ar or bigger should hit 750hp.

It flows less air than a regular GT3582R? So theoretically a regular GT3582R should make 750+ ... Sorry, not going to happen.
