yesterday when I was driving my xr6t randomly just cut out ? wtf? I pulled over and started it back up and it has been fine since? I was doing like 60ish and just cruising ? any ideas?

aslo im dying to get over 300rwkw ! ive got 295 on 15.5psi , I took it to a tunner to have it looked at cause I wasnt sure it was tunned right as I bought it from a mechanic but wasnt 100% confident in his work considering the oil was old and airfilter really dirty etc, so I took it to hitorque and asked them to have a look at it for me , they ran it and said it was running a little lean down low and they fixed that up and dropped the psi from 16 to 15.5 and still produced the same power within 2 kw,

its much better through the mid range now , very happy with that , before it was like nothing then everything but know its much better.

but I am dying to get as close to 350 rwkw as possible , my friends bf xr6t has 360rwkw and its a whole different world from 300 :s and I want to get as close to 350 ish as I can ,

so I was thinking about going back to the tunners and asking them to bump it up to like 18psi ,

what is the most boost I can run on my stock internal ba (except valve springs) I know 18 is rather high , is any one out threre running 18 in their ba ??

its got a eboost 2 so I was tempted to just turn the boost up to like 18 but I am not game to touch it cause no doubt more boost means more fuel so if I turn it up it will be running lean and I would probably kill it :S correct?

03 ba , 044+ surgy , 60pound injectors , valve springs , 2half with 4inch dump , underbattery air intake, BIG proccess west intercooler , 295 rwkw 15.5psi

any positive feedback would be apreciated , and its got a beffed up gearbox and I am pretty confident it can take 350 , I hope

If it hasn't been run up that high before it should really be done on a dyno with all the diagnostic gear plugged in. See what runs out of legs first without making it go bang. Make sure the exhaust has no restrictions.

sorry exhaust is twin 2half with high flow cat , and 4inch dump pipe , cheers

What intake manifold does it have? I was running 325kw at about 15psi so you might be ok. Is all your pipe work free flowing?

its got the full process west throtle relocation kit and pipping etc , the intake manifold is standard , I thought the stock manifold are easily good for 350 ? 325 at 15psi is pretty decent ! what tuner did u use?

Darren Van Nes here in NZ.

Seems you should get a little more. Is your pipe work from the turbo to the cooler all good?

Not sure if my auto would make much if any difference.

You seem to have all the fruit.

Maybe my 3.5" exhaust makes a difference?

hmm yah I duno , mines auto aswel , ill im going to take it to a tuner on the north side of briz in the next few weeks , if 17psi gets me close to 325rwkw or even 18psi ill be happy at that I think , for now, cheers

Iv got similar mods makin 385 on 18psi thru bf1 (ba) bottom end... Goin well so far

I was on 313RWKW at 12 PSI, pretty similar mods. ( 42 pound injectors and walbro intank pump. )
