ya i know its richer but i still have the stupid banjo fitting at the rail so now i need to run the new fuel lines and decide on the injector size im thinking 680cc i dont want to pull too much fuel with a stock ecuIJ. said:Q: I'd be expecting 450+ for that big a turbo but it all depends on the map it might go nuts after 20psi
So you're running this on a stock ecu?
<Ninja edit> Sorry just saw the running out of fuel issue that explains it.
(you do realise 10:1 is richer than 12:1 don't you)
new 70mm turbo install

i recently bought it from someone on this forum, havent even gotten it in the mail yet....should be any day now. there was a web site, i forget what it is, that sells these (t70 and other similar framed turbos with garret center sections) for dirt cheap. i know a guy here in ohio that has one of these t70s with a .68-ish a/r on his 7m. he put 13k miles on it and its still in perfect shape (doesnt smoke, still pulls). i think he only payed $300 plus shipping brand new....no shit.cactus_mole said:

so its not a masterpower T70...I'm getting one soon most likely with the .96a/r hotside but I think thats too big.
yeah thats what I wanted to get...maybe i'll get the .96, be a badass and rev my engine to 10,000rpm :sarcasm:supra_ed said:

with that size turbo you shouldnt have any issues, esp if you have an adj afpr. on a 61mm turbo i tuned i only had to pull at the most -19%. most of the tuning was in the 12-15% range. i had adjusted the fuel pressure down to around 32 psi instead of pulling the fuel w/ just the afc.
congrats on the numbers so far! on bigger turbos its common to have a leaner spot around 4500 rpm and then go rich around 5500 rpm. stock and small turbos it will go pig rich right at the 4500 rpm mark, but with larger turbos this is the point of when they come on hard and actually will cause a slight bump on the leaner side. ive noticed this on 4 cars ive tuned.
