Re:HOW MUCH BOOST???
All depends on engine management, Not how many miles, not what kind of turbo, its all in how well its tuned. I think the most stock sleeves can take is around 14-16psi, but thats really pushing it. A realisitic # is 10-12psi. Keep reading through our forum

Re:HOW MUCH BOOST???
I would highly suggest tuning on a dyno with wideband to get your A/F's dead on, before you start to bring the boost up.
People dont understand how tuning is so important, and if you want it to last, its really the only way. Jeff |
Re:HOW MUCH BOOST???
what would u say the best a/f should be 14.7/1
|
Re:HOW MUCH BOOST???
kinda lean isn't it?
seriously i dunno what's good a/f, that's why i asked.. should i tune myself?? like all i have to do at the dyno is make my a/f curve around 13 or so right??? |
Re:HOW MUCH BOOST???
11.8~12.4ish
wideband Air/Fuel |
Re:HOW MUCH BOOST???
so would i just adjust the boost and fuel pressure accoringly? that would adjust my a/f right?

Re:HOW MUCH BOOST???
That is correct, when your on the dyno, I'm sure the guys running it can give you an idea of whats going on Too lean/rich etc..
