Whats the spec of the car?

Whats the use of the car?

What are you trying to achieve?

There is a lot more than just "XXXX"rpm.

That are many factors to give a definitive answer... like engine capacity, cams, tune, additives etc etc.

Basically put, my thoughts are this

Stock capacity RB26 - GT-SS/2530s only. No bigger.

2.7/2.8ltr - 2530/GT-RS

so when do standard gtr turbos start boosting and when does it reach full boost ?

assuming that the engine is standard with just some bolt ons like exhaust, power fc and filters .

cheers

gt-ss: about the same as normal GT-R turbos

gt-rs: around 1500rpm later depending on other mods

a bog stock one would start boosting from very low rpm

but they don't make meaningful boost until about 3300rpm, and usually get full boost by 4000 or just past

what is this 'full boost' thing you guys speak of? i'm also a bit confused by meaningful boost too. is that like meaningful sex?

I think they mean if they set the EBC at say, 1 pound, they can claim to be on full boost by 2000rpm. :P

My Garrett's are producing full boost by 4500rpm. But if I moved the set point from 15# to something more interesting it would take until 5000 or more. Ofcourse I could also install a ghey intercooler & choke the airflow to allow the turbos to produce "full boost" earlier.

All boost is measuring is the degree of failure of your induction system to let air into the engine. It is nothing to brag about.
