ETS Quick spool Turbo kit(G30)
Thanks man.
It's a tight fit, but with some patient you can do everything. When installing the header the water radiator has to be removed. We first fit the turbo on the header outside the car and then you move on installing and tightening it on the block...
G30 770 is a smaller turbine (physical wise) than 6062 as it has 58/71 compressor and 55/60 hot side, meaning that should be more responsive.
What still has to be proven is the power rate that Garrett is claiming.
If everything goes well with Corona virus in couple of weeks we will Dyno tune the car.
The plan is to push the turbine at it's limits using pump gas 100oct (European fuel).
Fingers crossed the thing looks very promising

Looking forward to your results.
He answered the question in your favor so no need to debate. Garrett Motorsports recommends <1psi post turbo pressure on race engines so if he is seeing 7psi at 850whp on a 3" exhaust then you have the answer. Higher post turbo pressure will increase your drive pressure, which make the setup less efficient and makes the car more knock prone. I used to log post turbo pressure on my topmount setup with 3.5" off the turbo and with the GTX3576r I was in the 1psi - 1.5psi range. Haven't measured on my new setup, but I also went 3.5" right after the 90deg dump off the turbo.

If you have 5psi post turbo that suggests you would benefit from a larger exhaust. Whether or not you are happy with the current results is a different discussion. Not knocking your results, but I disagree that 3" is not needed until 850whp because based on your data there are clearly efficiencies to be gained.

In theory, backpressure increases approximately with the square of exhaust gas flow. So an engine moving 800hp of air would have 4x the backpressure of an engine moving 400hp of air, everything else equal. Everything else isn't actually equal, but you get the idea. Backpressure measurements don't translate well across wide ranges of horsepower.
Backpressure also increases linearly with exhaust length, and we have a very long exhaust. It's basically the full length of the car, plus some significant bends at the start.

So, this is a 2.2L Evo8 (no mivec), Hess games pocket port head, GSC S2's, Curt Brown ported intake and 65mm throttle body, ETS 3.5" intercooler and Vband turbo kit, G30-770 .82 AR vband hotside. Walbro 525 pump and FIC 1650 hi-z injectors. 614whp at 29psi, we ran out of fuel. But Aaron feels like he could easily push the turbo to 36-37psi based on how it was still picking up boost with more wastegate duty cycle.
It has 300wtq at 4300 and 400wtq at 4650.
It's more responsive on the street than the dyno sheet makes it seem. Definitely an awesome turbo setup.

Excellent top stuff well done guys!
What kind of fuel have you been using?

That was E80 in the tank. It's a full flex fuel tune though. It made 456whp at 21psi on 91 octane pump gas.

Nice part is that it keeps the power all the way up to 8500rpm wow.
How does it feel on the road?
