My setups is all finished, but no Boost!!!!!!
 

Hey guys, ok heres the deal, i just finished my first hmt setup (1989 CRX, stock D16A6), and i'm having problems building any boost whatsoever. I am using a TEO4h Mitsubishi turbo off a daytona, a log manifold that i made, dsm sidemount intercooler, Ghettodyne boost rom with dsm 450cc injectors.

So i just started it up today, and it runs a little rough at idle...sorta like a pulsing up and down on the tach from 700 to 1000 rpm all the time. After i let it warm up i started reving it in neutral, gradually intill about 3500rpm. My boost gauge which has VAC and Boost on it would stay at like 15 inches of mercary then when i rev it go to 0 psi. I looked at the wastgate and its not opening, i checked charge pipes, no leaks that i could see, and i have no clue what the hell is wrong. I have not actually drivin it yet becasue it was late and i didn't have time to. PLEASE help me!becasue i have no clue whats wrong. Thanks Alot guys!!!

You probably arnen't going to build any boost just revving it up. Take it out for a spin and see what happens.

Are you reving it while stationAry?

You need to put a load on the engine in order to see boost, aka get it on the street and drive it.

What kind of BOV setup do you have? Do you hear it go off?

Re:My setups is all finished, but no Boost!!!!!!
 

I have a "monza" BOV, prob simular to the ones they sell on ebay. But since i reved in neutral, and i have yet to road test the car yet, i will sooon find out. :-[

If you have a single diaphram bov, they usually throw some sort of noise when you chuck a rev real quick. The real test is of course driving it.

Monza is similar to the HKS SSQV BOV. If you rev it in neutral you'll see it open up as you are push and let go of the gas pedal.

15" hg is a pretty low vaccum for idle
sounds like your timing is off or your vaccum lines are fucked somewhere
