my vortech sc with 3.12 pulley in only boostin 5psi..
during my dyno runs, 1st pull was 5psi then 2nd pull was only 3psi

what do u think is the prob? major boost leaks!??

 

WTF, I thought you got that worked out man...

Did you check all your vac lines? are you running the 93" NAPA belt with the 3.12 pulley? Please tell me you are not running the stock belt...

How much can you turn the rear cog belt?

Is there a leak in your plenum gasket?

What R4 Map are you running? Did you get it totally tuned?

I can try loading a map I have in my Laptop into your car if you wanna give that a try...

 

the vacum leak is already fixed
now my prob is prolly is a boost leak, just wana hear some other opinions from other vortech owners here incase thats not the prob. we'll try to check all the clamps and hoses when i get back there in az this week..

i have the base map as of now..didnt have the chance to have it tuned last time coz im only running 3-5psi

plenum gasket? that..im not sure..we have to check and im not running the stock belt. belts are totally fine

 

What were you seeing with the 3.33 pulley??

 

I built a G35 with a vortech. We found a leak inbetween the flat side of the MAF and the charge pipe. We had a custom MAF housing made and it took care of the leak. Made a night and day difference with the car. PM if your interested in one.

 

Any pics of this device?

 

I wouldn't be running the car at all on the stock tune with the 3.12 pulley. IMHO you're asking for trouble.

 

your probably going to have to preasurize the whole system to find out . I made a capped off pipe with a air hose connector on the end of it . I broke the intercooler pipe right before the BOV and hooked up the pipe I made there . I then capped off the exhaust so it wouldnt leak . Hooked up the air compressor and started listening for leaks . I set the air compressor for about 50psi
