what turbo for 650hp

[|CL|NIKI]

Absolutely. - Motronic + 100mm MAF housing (after the turbo) + 870cc Deka inj + 100 octane fuel.

And what kind of wastegate?

The car should make more like 800hp with that setup and ethanol.

650hp can be made on pump fuel with 8.0:1 CR and a GTX3582. I also had 2.5 bar at 4800 rpm in 3rd gear.

5000 rpm and only 2 bar, especially on ethanol really sounds like your cams need to be adjusted.

And what kind of wastegate?

Stock one with 2 springs (1 stock,and 1 I don't know from what) and Greddy B spec 2.

prj - You mean My one? The cams are set by specification, and are 4-5 times measured before Dyno runs.
HTA 3582r newer can reach 800 Engine Hp no matter at what pressure I think.

[prj]

Yes, I mean yours.

I use Wat/Meth inj. just to spread water with the smallest nozzle....

You said E100. Do you mean 100% Ethanol or 100 octane pump fuel?

With 7A cams and 100 RON on 8.0:1 CR and normal GT3582, 611hp. No methanol injection. Full boost 4500 RPM.

So there is definitely something wrong with your setup if you spool so late.

100 octane fuel. This cams are with much more lift and overlap than 7A's. The CR is not clear known, because I am with stock pistons - just 2 gaskets under the head....
What You mean with "Full boost" at 4500RPM from GT35 - full bust that can support the turbo or max set pressure?

Full boost - maximum mapped boost. In case of 611 hp car 2.3 bar.

In case of car with GTX3582 it had Shrick cams for 7A, so a lot of overlap as well, and still 2.5 bar at 4800 rpm.
Catcams you have to clock a bit differently than what is stated in the manual.

Isn't that a little more pressure for 611 hp or...? I got 640hp from 2.1bar boost.

Depends how well things flow. Also, different dynos can easily have differences in hp up to 100 on this level.
So this is not telling the whole story.
