Efficiency Of Gtr Turbos

[cefiro]

hey guys I am no good at reading compressor maps, but I have some steel wheel GTR turbos and I want to know where their efficency lies at???? what boost will they be be spinning too fast and blowing too much hot air and heat???? want to run them at about 18psi maybe 20, just squirt it now and then, with NO track work etc,

cheers

They will be fine at ~ 1.2 bar which is 17 PSi for everyday driving with the occasional squirt.

Cheers mate, I dont think I am going to make the power I was after with these turbos, I would like about 280-290rwkw, Hope I get there, currently making 252rwkw with PFC, exhaust and boost at 14.5psi

Lets hope we get close

IIRC the stock injectors peak out at about 280kw with a safe tune... and maybe AFMs and fuel pump at about the same level??

im leaning the same way as you.

I wanna go n1 spec turbos @ 16-17 psi, and aftermarket ecu. Are N1's slightly bigger than stock gtr turbos?

want to retain the stockest possible setup.

hopefully i can make the high 200rwk's

Yep, N1s are a bit bigger

I have run steel wheeled stockers at 22psi - they wont hold that to the end of the rev range (seems to taper off to 18 ~ 19psi or so towards redline). But they feel GOOD when they come on as they spin up quicker than most N1's I know of. Air temps were a non issue.

Brilliant turbo for a street or tight circuit RB26
