PQs Camaro [COTW 9/20/10]

So it looks like just the boost isn't reading right.

The misfires are in the history. Could have been old shit that never got cleared out.

Hold on. Brain just started working Brb

Had to be in the timed log. I suppose.

Convert 157mm/mercury to inches



Vacuum/boost are referenced off of inches of
Mercury.




Maybe?

That's obviously wrong. LOL

Off the top of my head I think that kpa is 8 psi. There is more than just using the online conversion calculator. My car is at 220 kpa which is 17.2 psi.


I think the stalling is some sort of idle adjustment but don't quote me.

Hmmmmmmmmmm..................

I wonder if I should start a thread and see if any of our tuners want to help out in decoding this.

SCT measure intake manifold pressure on kpa. I was just trying to decipher mine last wknd.

Well damn. If I'm at 8 then something is wrong. Maybe because it's not as hot as it was when my car was dynoed which I believe was over 100 degrees and high humidity after 6 pulls already.

I'm just guessing. Someone smarter than me will know the correct conversion. Did you expect less or more?

Ok good to know.

Disregard that post then.

If its 157kpa, then that converts to 22 psi. Umm no.

Expected around 6 to 7. It's the 3.2 pulley not the 2.8 I have.

I just want to get an acurate reading before I put Teds tensioner and 3.4 on it.

you are on the right track. He's around 8 PSI but it could vary depending on his elevation.

Ok, all the other variables convert easily from metric,
And make sense. The speed and the engine temp are right on the money.

So either we have the wrong reading, or the wrong original type of measurement (kpa or mm/hg)

Sea level.

Sweet. My boost gauge reads right at 7 1/2 pounds-ish.
