Im getting 25 psi boost w.o.t should it be more or not? if so what to do? will more boost help it run better without getting too lean or is it fine? soorry for all dumb questions to you gooroos :

Hired Gun

I just put a Power Max 3 and am getting 30 or so on mine its a 99. No problems yet.

Did you put in a different boost elbow whiteknight?

whiteknight

Hey chuck thanks for the message,i did change the elbo with the one that came with EZ.is there an orfice # on them or how can a guy tell which one i should get? the hole was pretty small on the one i put on.

I get 30 psi out of mine. But then again, I used the turnbuckle method so I can adjust mine. I don't know if it will really help you any performance wise. If you have black smoke at full boost, then yes, more boost will help performance. If you only have a slight haze, then no, it won't help much, if any. I don't think you can really run it to lean. I could be wrong though. Just watch your EGT gauge. If the temps get to high, back off the boost a little. At least, I'd think that if your running to lean, the temps would be to hot.

thanks big blue, i guess maybe im alright then, i get a small cloud when i shift but thats it as far as smoke.

Sounds bout right.

Don't worry about running it lean. You can't get it too lean. Basically, after you let off the accerator, you lean out the engine and it slows. What you have to worry about is running rich. This will cause high heat and worse! This is what smoke comes from. <br><br>Remember, gassers are way different than your beast! If you add more fuel, you may need more turbo boost. If you add lots of fuel, you need twins!<br><br>See, clear as mud!<br><br>Dave

i here that thanks ;D ;D

I think 35-40 psi is max on the HX35.

StakeMan

Pushing a turbo to far out of its map just creates more heat. I wouldn't take an HX35 beyond 35 psi. I was getting 32 psi out of the HY35-9cm. When I removed it I found a large crack in the exhaust housing around the wastegate port.

For a stock HX35, I have heard that mid 30's is max. Nor a Piers 35, well that's just a different story!<br><br>Unless you have lots of smoke or high EGTs, you should have plenty of boost. <br><br>Now don't quote me on this, but I remember someone saying that the engine typically requires about 10psi per horsepower. Maybe someone more enlightened on the turbo front can answer that question.<br><br>Dave

<br><br> Sorry Dave I know you said don't quote me but, 10 psi per HP means at 32 psi I'm only 32 hp, bummer I though I was over 300 hp. Just kidding ya. ;D ;D
