Max Psi And Hp With Gt-ss ? On Rb26

[cobrAA]

Currenctly making 425whp and 350lbs of torque with a set of twin GT-SS.

I was wondering what should I expect from them if I rebuilt my rb26 and go for higher psi..

Thanks!

how much boost u running for 425whp?

E85 an option

I believe u can get em around to 350kw

check out 26 dyno thread for max numbers

That is fairly close to the max you will get out of them as is.

As stated E85 will get you further, yet they are fairly on the money for their efficient max on 98. Remembering that you have over 310rwkw, another 20 would be the most you could get (and the question is raised is that even worth the outlay?).

Yup as said above, only thing left on these turbos is some E85 fuel.

Once you start rebuilding the engine you really should look for bigger turbos to make the most of it.

With a nicer motor, bit of head tidy up etc you should make 330-340rwkw on 20-22psi like everyone else does (ie, use the search.)

really? that seems low. I mean I don't even have cams or cam gear. I'm at 17psi.

I did some research before buying the gt-ss and they were rated like the -9 which is a tad more powerful than -7. My friend with a rebuilt rb26 run 460whp with his -7. So, I was expecting close to 500whp

what country?

Im currently making 380kw @20 psi from the gt-ss turbos with the 2.8 Tomei engine kit in my gtr. My tunner said i am having problems with the electronic boost controller as it is having problems holding boost over 20 psi.

Im happy with the performance at the moment @20 psi but will eventually get a new controller for it.

380rwkw from GT-SS's? On PULP?
