max boost
Re: max boost (r32gst)
zerothread/306956With a tune you could maybe do more.
Re: max boost (zach-Ka)
it helps a little bit. what do you guys think of the set-up
Re: max boost (r32gst)
I was boosting 1.4 bar on my 180sx with a black top when I was in Japan. I think that's 20 or more pounds. SR's can handle a grip of boost. my ish was running strong to, it would definitely snap your neck back.
Re: max boost (nisjay)
do you have a wideband?
what were you running on a daily basis, whats your afr at wot?

Re: max boost (r32gst)
your h/g is a limiting factor as well
Re: max boost (maryjane)
whats h/g mean.... i've been just tuning on the afc 1maryjane wrote:your h/g is a limiting factor as well
Re: max boost (r32gst)
head gasket and afcs are not good news. rom tune ecu and wideband are better then afc tuning.

Re: max boost (r32gst)
so i have my 240 running 16psi. the a/r is 11.2- 117 in wide open. it's running super smooth. i love the power it's making. i just wish i can up the boost to 20psi or so... i have my boost controler max out. is there anything i can do to get more boost.... w/out pulling the vac off the wastegate
Re: max boost (r32gst)
Get a new boost controller. Do you have a T25 or T28? I would say 16psi is a good amount for daily driving an SR. Those are really strong engines. Like I said I was boosting 1.4 bar and ripping on it everyday, I never had a problem. It was a skyline killer, GTST anyway.
Re: max boost (nisjay)
right now the turbo in the car is the greedy 18g. i still have the t25. the disco. i wanna sell it, it just sits here now. oh and i'm on 18 psi it's so much fun
Re: max boost (r32gst)
well if the afrs are in the 11s then your fine what w/g are you using? upgrade to a hks actuator to up it
