(pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

hi guys i just got done doin my turbo dsm set up install on my prelude with a f22a1 every thing is stock rite now like i didnt do anything else but put in the dsm injectors , dsm manifold,14b turbo,h23 intake manifold, jdm h22a lsd tranny,and front mount intercooler. every thing is on the car except im running open o2 housing rite now and when i go to wide open throttle the turbo boost starts to rise to 15-16 psi on like 5200 rpm! so i stop driving it .. now i was wondering why its boosting soo high so guys let me know what can it be thanks

ps i thought 14b boost at 7-8 psi ?


Well heres some pics of my set up pretty much done just needs down pipe made and dyno tune when i get some cash and install my turbo timer also thanks alot for help to:

LSD Motorsports - for helping me wtih the intercooler piping layout and shipping me the intercooler hehe at mid night service lol thanks alot man great service

Mwinkle for helping me with the boosting problems

and my boy roland for helping me with the ecu problems

and midniteracer for my ecu socketing service

dont laugh its kinda ugly rite now but yea i have bunch of other stuff i will add in a week so ill keep you guys updated ;D

your either creeping, or your wastegate is binding/bad/doesnt work right

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

what do you mean by creeping? and also how do i know that the waste gate is bad wat are the symptom thanks guys

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

make sure the wastegate isn't seized shut and check the vacuum going to it

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

how do i check vaccum goin to it?

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

The symptoms of a creeping wastegate is hitting 16psi off a 14B. The boost is "creeping" higher than what the wastegate spring is set to.

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

so that means my wastegate is bad then rite ?

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

Possibly. It should be the first thing you check.

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

14b wastegates have a diaphram(SP) that leak when up there in age, I have seen a couple at work.

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

do you really have jun parts on your dsm boosting lude?

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

also what are you using for engine mangement???

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

Check your wastegate and hoses. I have a brake bleeder vacuum pump that can be used to supply pressure on a dead head system like a wastegate actuator. Pull the hose off of your vac/boost source and pressurize the hose. The actuator should start opening up at 5-8 psi of pressure. if not something is keeping the valve closed against the port. If pressure doesn't build, or it bleeds off really fast, then the diaphram within the actuator assembly is torn.

Another thing to check is your vac/boost connection. Where is yours located? Directly to the manifold? From the turbo's compressor's housing? Those are the two best sources to get the signal from. if you have it hooked up to the brake booster hoses/lines, then you chance haveing a problem with a check valve within that series of lines. If the actutor can't see boost, then the turbo will continue to built pressure because it has no way of venting the extra exhaust around the turbine wheel. The best thing is to use a dedicated line for just the wastegate actuator from the before mentioned sources.

Good luck and let us know what you find,

THANKS ALOT MAN !!!


this guy helped me out on aim and i found out what its was my vaccum line i was using had a check valve in betweeen it so my wastegate had always been cllosed because the check valve did not allow any vaccum through to actuate the waste gate thanks man but pics coming soon on my just finished f22a turbo

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

good stuff...

im still waitin on a camera man

i bet u my set up is more homemade than yours!?

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

Glad to help where I can. I may be new here. But definately not new to turbocharged vehicles.

By the way, how's it running now?

Get some pix up!

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

bump its up now guys let me know what you guys think dont worry my exterior is goin to be better in a week just havent had time

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

car looks good, you need to get a filter or atleast a clamped on screen on your turbo inlet, just one small rock is all it takes to ---- up your turbo. other than that, lookin good!

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

i like the way it looks but not a big fan of the "ludes"

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16ps
 

looks good, you just need to center your front mount and straighten it out.

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16ps
 

yea that why i was saying dont laugh ;D but thanks

Jun is all about the SOHC non-vtec engines nowadays.

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16ps
 

looks good!
that radiator hose fits great for the charge piping right out of the turbo.
perfect bends.

Re: just got done wtih my f22a turbo dsm set up but why am i boosting 16psi?
 

nice but

Re: (pics)just got done wtih my f22a turbo dsm set up but why am i boosting 16ps
 

thats what i was gonna say too.

I noticed in this shot that on the compressor it seems to be missing the vacuum nipple that feeds into the wastegate... you might want to plug that up if your not using it.... otherwise your gonna be leaking boost....

fyi...
