2 psi at 5k wtf need help asap

kennydawgg · 05-25-2007

I got the clipse up and running, idles fine etc. problem I am having tho is I get no boost the highest I have gotten is around 2 psi at 5k definately not right. The bov is also not functioning and I am getting compressor surge. I have a greddy type s with the vac hose hooked up to the intake near the buterfly. It is set on the lowest setting but it still does not open.

I have 2 boost gauges, one is the e-manage sensor that gave me the 10 kpa reading and the other mechanical gauge is hooked up to the same line as the fpr and has not shown any boost. I checked with my air compressor to see if it works and it does.

I also checked all the ic pipes and clamps, sprayed them with soapy water and none of them had any leaks.

any Ideas?

its a 2.4 spyder gs btw

Do a boost leak test.

Wastegate stuck open?

**JET** · 05-26-2007

BOV could be stuck open too. It sounds like you may have done a boost leak test, if you did then I think Steve got it.

should I be able to move the actuator rod when the car is off? Im thinking this might be my problem

Yes, you should, but you'll want to grab it with a pliers to move it.

ok the waegate moves then springs back, I took the bov apart and removed one of the srpings, its a greddy type s, no the comp surge is gone but t stil only bosts to 25 kpa at 5k rpm, still strange could it be that the aegate flapper does not seat right?

What kind of turbo and wastegate?

kennydawgg · 05-27-2007

14b stock wastegate

"its a 2.4 spyder gs btw" Could you give us little more info on your setup? Who install the turbo kit. Where are you tapping for you turbo Gauge? Does it bog when you boost? More info will be nice.

i installed it, I have the boost gauge tapped in to the uicp just before the throttle body. It has 510 injectors, emanage, 14b turbo, no cat and a stock downpipe, a 5zigen 2.5 inch cat back and a mbc (just a cheap valve type)

I figure my boost gauge is junk it never moves, i added spacers to the bolts on the wastegate actuator to make sure that the wastegate is closing and it had some slack when I unbolted it. its running a little rich now but it idles and runs fine no real bog or stumbles but I have only riden as a passenger as I have no licence until wednesday, i am gonna order a new boost gauge and hopefully have it this week.
