hp at 16 psi?

DSMmonster92 · Nov 10, 2010

hello all, i have done quite a bit of searching and i can't seem to find the answer to my question. i'm wondering what my hp level would be if i turn my boost up from 5 psi (stock level) to about 13-16 psi. it's a 1992 laser rs and i have all the maintenance up to date. i also installed a mechanical boost gauge because i here the stock ones are garbage.

another thing, is it normal for me to be boosting about 5psi on stock setup? i read it was 7-12.. 5 just seems a little low, also my vac is reading around 24psi at idle.

Thanks in advance, Dan

Well every cars horsepower number is different so there is no way of tell you that unless you go put it on a dyno. My car on just wastegate runs 10psi. Are you still using the bcs?

DSMmonster92 · Nov 10, 2010

i understand that, i was just looking for a ballpark figure.
i'm sorry but i'm not sure what bcs stands for.

yea the only way you can tell is to put it on a dyno and BCS= boos controller system....

its actually boost control solenoid, and a search for bcs mod here would bring up exactly what it is and how its done.

ok thanks guys :hellyeah:

does 5psi on a WOT pull seem low for stock? boost leak maybe?
and what about 24psi vac at idle?

major boost leak man, what gear are you seeing 5psi in a wot pull?

stock boost is 11-12 on a 1g IIRC

do a boost leak check, it could be a boost leak, but also at the same time, it maybe that in your area, altitude and all that effect the vacuum.

i did the WOT pull in both 2nd and 3rd gear

habitatguy187 · Nov 10, 2010

Way too low, even for altitude. Check for boost leaks.

It would bring the stock power output from "pathetic" to "acceptable".

Fix your boost leak first.

sexystover · Nov 10, 2010

fix the boost leak and do a pull in 3rd or 4th

Do a boost leak test and fix the leaks because 5psi is not normal.. Test another gauge also to see if your current gauge is bad.. What does your stocker gauge read?? As for the WHP question there is no way to tell different cars run different numbers on 16psi.. Your going to be pushing your stock fuel system on 16psi so make sure you dont go over.. My brother ran 270whp on a dynojet on a 14b with the right supporting mods and a tune.. He had a 2nd gen (14b swap).. Goodluck!!

gsxeclipse97 · Nov 10, 2010

Also check to see if your turbo has shaft play. With a leak that big I'm surprised that your even turns on. the 14b is a small turbo but 5psi is unheard of at wot. the factory spring is 9psi so you should at least be at that. Another thing for you to check is the waste gate to make sure that your spring is not stuck in the open position. that is the only other thing that would allow you to run such low boost.

and I think you meant 24hg at idle

5 million horsepower but thats at the flywheel

Misterbeechy · Nov 10, 2010

hahaha^^^^^ and due to drivetrain you only get ~194

You don't want to try to run 16 psi on the stock fuel system. I know I get fairly close to hitting fuel cut at 15. If you don't have a logger to check for not or at least a wideband to check your AFRs I would think about turning up the boost. Also realize your whole exhaust us a restriction until you mod it.

Absit · Nov 11, 2010

No one mentioned out that I saw but your vacuum should NOT be 20+ PSI, ever. Either that's InHg or your gauge is broken. Even if it is InHg, 20+ at idle is crazy high.

Most gauges are going to that system. It stands for inches per mercury. It is literally barometric pressure that it is measuring.

Spoolin4Ever · Nov 12, 2010

Turbo could be going out. When mine did it would gradually go from the stock amount down down dwon 9 8 7 6 5 3...and I replaced it. That was the original 14B with 125K on it.

Take the hands you typed this with an slap yourself with them. Another noob who doesn't understand fuel-cut. How is 15psi getting you close to this 'fuel-cut'? Literally, there's zero logic to this. Is there a magic feeling or warning only your DSM gives to let you know of this impeding doom?

You're so wise. Great advice. You should be the head wiseman here on Tuners. Your knowledge overwhelms every inch of my puny brain.
