Boost PSI?

**kfish** · 01-13-2010

ive got 15-16 on my 3.5...with headers. sooo idk. no knock though. so boost me up!

That's nuts. I think YOUR gauge is broked. LOL

I saw about 17 or so on a 3.1"...and it was about 35*-40* outside. I wish I could have had bigger injectors to see what a 2.8" would have done

Hear that fish? its BROKED! Thats about 3.5 times more serious than broken.

But seriously, it IS a lot of boost.

**kfish** · 01-13-2010

not broken. ive been through 2 guages both read the same. and im t'd in at the lim. so HA! my car just boost stacks like a mofo. but no knock so no harm. imagine me with a 2.8 though...

It'd be ratared.

**blueguy** · 01-13-2010

Yeah, that's insane. If you're actually that high, you're probably losing a ton of power by not fixing whatever is wrong, even if you are keeping it from blowing up.

**kfish** · 01-13-2010

nothing is wrong...idk what could be wrong honestly.

**Scimmia** · 01-13-2010

With a roots blower, all boost is caused by restriction. Somewhere in your system after the LIM, you have some serious restriction. Someone didn't clamp your catback shut, did they?

**kfish** · 01-13-2010

nope. headers will full 3" exhaust all the way to the cat back. oh and no cat to be clogged either.

**Scimmia** · 01-13-2010

internally collapsed muffler? Valvetrain issues? leave a rag in the wrong place? If you're positive it's not a false reading, I would keep looking.

**kfish** · 01-14-2010

heads were rebuilt when i did the top swap, im not dumb enough to leave a rag in my motor. it just boosts stacks. idk why

**blueguy** · 01-14-2010

It boost stacks because ALL roots type blowers boost stack...thats how they make power.

**Bio248** · 01-14-2010

boost stacking is a stupid term.

**BoostedComp** · 01-14-2010

i agree lol

**kfish** · 01-14-2010

bio do you see a problem with my boost situation?

Hijacked an Autometer from a friend. 6.5psi(redline). ~*32 ambient. Vac. = 17hg(idle). Time for a new gauge. MY autometer was showing 4.5 in mid 20*(redline) with Vac at 22hg(idle). BS.
