fuel is cutting out at 6000rpms!!!! (any more ideaas?)
 

ok, running 9 psi on a t25, with afc, I've been running fine for the past 3 weeks, not problems, but just today it started acting up. in first and second gear when I reach 6000 or 6500rpms, it seems that the fuel just cuts out, I doubt it does because it was cause major damage, but the car looses all power until I drop below that rpm, and change into 2nd gear, then it's good to go until I get over 6000. I red line at 7200. and ideas? I had it tuned and it's giving the right amout of gas. Maybe something is wrong with the turbo its self. It has about 25,000 on it, off a 98 eclipse, and it has no shaft play at all.

Fuel Pump :-\ :-\ :-\

that's a possiblity, didn't think of that, and it actually does kinda feel like that, because my other car's fuel pump is going out too but it jerks all over the place at low speeds.

get a Apex-i SAFC
i got one for my 91 d16a6 and its under 10 psi now and it works fine.. well i also have a MSD5 too. but fuel wise a safc will fix that.. i myself dont sugest taching it up to 7200rpm.. i shift at 6000 at the most.. and under 10psi it scoots.. pretty good ;D

^^^good info
I was wondering about that too
mine cuts out at around there too running 3200 RSX injector @7psi. I'm still not dyno tuned thou. The ECU has been making the correction for now
but i didn't think i should redline in a turbo car anyway. ::shrug::

I have an apexi SAFC, and it ran fine two days ago all the way up to red line, and I havn't changed anything at all on my afac sttings.

do you still have your stock catalyst in your car? the same thing happen to my car 2 weeks ago. i install a test pipe and the problem went away. my car ran alot better with out the cat. i'm not telling u to drive with out a catalyst. just use it as a diagnoise.

im running open exhaust
i think everything will be fine after i tune and same for your car
just need to take it easy
Im install a new fuel pump too
I really think this should take care of any other problems

Re:fuel is cutting out at 6000rpms!!!!
 

no, it's not the stock cat, it's a high flow racing one, not sure what brand it is, i got it used with my greddy sp catback. And speedracer32, my car is tuned, it ran perfect the past 3 weeks, just started acting up at 6000rpms?!

Re:fuel is cutting out at 6000rpms!!!!
 

no such thing as a high flow cat....also at a certain point the motor begins to "outrun" the turbo....meaning a loss of power, mine happens around 6500 or so, but it doesnt bounce around or anything like that...dunno if that helps or not but there ya go
