Yes...people have run 300+hp on fmu's and gotten into the 11's...over 10 years ago when current ecu technology wasn't too well known. At the time it was pretty much all they had to use. IMHO it's not the most accurate or predictable way to go. Sorry if I'm not Baller anymore, but I got sick of replacing motors a long time ago...why destroy it if you don't have to.

i've never blown a motor in my life

You're very lucky then. It's pretty sad now that I sit and think about it...I toasted more motors n/a than I did boosted...ain't that some ---- :P

bitchasscracker

lol becouse you gotta rev the ---- out of NA motors

Scott-EP

me too. i am still on my 1st boosted engine for over a year now

no one's say'n it the most accurate or safest way but it works, my buddy had a turbo 1.5 mini me with a sunbird turbo on it pushing 12-15psi for a year on a fmu before he swaped in his built z6 spent 120 on chipping the ecu 580 dollars to get it tuned (dyno time plus 150 and hour for the tuner) got a smaller turbo went back blew a brand new turbonetics turbo at only 12 psi now it has the tune from the turbonetics turbo before it blew, with the same sized turbo and it runs like mother ------- ***, my n/a b17 would eat it, the second time he went up there he paid 200 for the tunning, so in the end he spent a grand and made no progress, and this was work done buy a aem ems certified and crome certified tuner, really he should have just got a basemap and a vafc and he would have saved alot of time/money

12-15psi on a stock bottom end? i thought ringlands couldnt handle much more than around 9 psi for very long

bitchasscracker

it depends on a huge t-3 no


but a super dinky t-2 yes

ososlohatch

ya it was on a small t2 but none the less it was running on a fmu, and ran great, buttom end looked mint when we swaped it for a built z6, timing was a lil retarded through dizzy 3 check valves and a fmu, thats how we rock the 250 dollar turbo setups

The only problem I could maybe see with a draw through would be vacum pulling oil past the compressor wheel once the throttle plate is closed,especially when shifting at high rpm.Can't intercool a draw through either.
I use a holset hy35w from a cummins,on my dodge 2.5ltr minivan,no problems with the turbine @ temps close to 1600deg and almost daily driven for over 6 months.
