Hey guys & gals, I'm instructing at Roebling Road, and half-way through my second session, I noticed I didn't have full 10-psi boost anymore.

I checked all hoses, and haven't found any that have blown off.

I also checked the E-clips on each actuator, and they are all on there.

Vaccuum hoses to actuators looks good as well, and so does the hose to the boost sensor.

Typically, when in netural (no load) if I rev the engine quickly to 6500 RPM I would see about 4-5 lbs. I see nothing on the boost gauge.

Boost pattern when driving is a flat 5-lbs, not even 8-lbs.

Intercooler couplers looks good, and hoses to the two (2) relief valves looks good.

According to this: http://www.autosportracetech.com/RX-...leshooting.htm , I need at least 8-lbs of primary boost, before I even tackle the secondary.

I think when I do rev in neutral (no load) I hear a little "whoosh" of air.

Any help would be appreciated, instead of having this track weekend be a bust.

Thanks,
:-) neil

Maybe a long shot but did you check the intercooler hoses? Primarily the lower one? If you do then take it off and squeeze it since if it split the slit is hard to see if you dont actually squeeze the hose.



Good luck with finding the issue.

 

Yep, this is the issue.

Now, where can I find one or something similar in Savannah, GA, area !

If you have one in the Savannha, GA, area, or know of someone who might, please email as I'm stuck at the track (Roebing) without one.

You can drive the car with the cracked hose, it's just not going to be as quick.

happened to me twice on the stock i/c. i finally upgraded! yaaaaay

 

Unless you have the exact part pictured, I can't use anything else, as my bends are so tight.

Thanks though!

thats what i am saying i don't know exactly what i have... it is a huge tub full of stock twin stuff and various accesseries.... did you get ahold of darthrotary??? i know he has it!!!

 

I have the top peice of the pipe, It's the secondary lower IC pipe. I just replaced my stockers with samco's.

Throw me a pm.

 

I've been having a whooosh sound during boost (sounds like wind through a pvc pipe) but I just checked my flexible pipes along with everything I can get my hands on. My boost is fine but I'm wondering if i have a small leak causing strain on the turbos.

 

I removed the lower metal reinforcement (10mm bolt).

I cleaned the stock hose with brake cleaner and "Purple Degreaser" and got it really clean, dry, and oil-free.

Then I took "orange" RTV and just about covered the entire area.

Then I wrapped it TWICE with heavy-duty weatherproof duct tape.

Then I took wrapped the area with "muffler repair" sheet metal (I was going to use an aluminum can, but this looked tougher).

I re-installed the lower metal reinforcement.

Lastly, I used four (4) hose-clamps to hold the metal wrap together, and let the assembly cure for about 10-hrs.

NO MORE LEAKS!

PS: thank God, Advance Auto Parts was open until 9pm on Saturday!

 

Hahaha, nice fix but you should of used racer tape. The car would have been faster .
