well today was the first time i really got to taker the car for a good run. yesterday when i took it around the block it was boosting at 3 psi and it felt hella fast. well today after adjusting my fuel pressure to 47 i took it for a spin and i was boosting at about 8 psi and it felt jes about as fast as 3. wtf is goin on? i raced my friends civic h/b si(16.5 stock) he has intake and thats it. i let him take off a split second b4 i did and i didnt catch up to him till fuckin 3rd. wtf is goin on here? my boost guage reads 8 psi under full bost and i cant even beat that lil civic? sumthins gotta be wrong here. PLZ HELP!!! TIA

You changed what to 47--the static fuel pressure or under boost fuel pressure? If you adjusted the @ idle fuel pressure, then that's where it should, regardless of how many pounds of boost you're running. When you increase boost, then you need to turn up the under boost fuel pressure (which is the little brass knob, next to the check valve hose); and at 8 psi, it should be at about 80-90 psi, otherwise you are running waaay lean!

well i adjusted idle pressure. but do i need to have a check valve? cuz at the moment im runnin without. would that make that big of a difference

does it feel like you hit a flat spot around 5 grand? like you just stop accelerating.

another thing is that b4 i adjusted fuel pressure to "correct its setting"(47psi) i was reving to like 4000 and hearing blow off. know i rev it to like 5000 and barly hear it. can that also be related to that? and does it realy matter?

Please tell me you're not still running 87 octane. Cause if you are, you're getting silly with timing retard.

What was your idle fuel pressure set to before?

What might have happened was that your idle was set too high or too low, and once you corrected that to the appropriate level, your boosted fuel pressure also became skewed. (either by raising it or lowering it out of the recommended range)

What to do now? Check what your fuel pressure is at 8 psi. It should be somewhere close to 80 psi.

80 psi?????
the instructions say 105-110psi at 8-9 pounds.

if this where the case then that would be hella rich if the instructions are wrong.

Good catch! That's what I meant. 9 psi should give you 105-110 psi. That means 8 psi whould be somewhere close to ~100 psi.

Of course, the point is still valid in that you have to adjust your boosted fuel pressure after screwing with your idel because one effects the other.

Ohhhhh, the joy of turbo fuel systems!!! LOL Dont you just love it?

well i adjusted the fuel pressure again today but i wasnt able to adjust boost fuel pressure cuz i dont have a check valve. o and dont worrie 91 is what i got in the tank.i left the fuel pressure guage on to see what i was at at 8 psi and in first it would barly hit 73-75 second bout the same and 3rd 80. so i guess im a lil short of 100 huh ? if it is that off will that affect my hp THAT much? or jes barly? cuz i ranmy freinds civic today aagain cuz it felt a liiiiiil bit faster and i beat him but not buy much. and i was shifiting like at 5500 cuz boost would die out alot. if i reved harder we would be even. hopefully tuning the boost fuel pressure will help alot. le me know TIA

so guys!!!! what could be the problem? when my car was running i was loosing power at about 5000 rpms. i was having the exact same problem as him.

also make sure your clamps are tight. i thought all mine were so i rulled that cause out and when tore my engine down i found the upper ic piping (one at the rubber elbow) and found the clamp just hanging on the pipe. so now i don't know if that was the problem now.
