[s-cars] Drastic Power Loss-Lonong

[Manuel Sanchez]

Ian,

I've been assured it was greater than 27 psi, and that the hoses held  
the charge of air when the ISV, Throttle Body and the crankcase  
ventilation system were plugged. This was when the system was  
pressurized just south of the turbo outlet. I have asked that we get  
a measurement with a pressure gauge so I can officially rule it out.

When I did the pressurization in my driveway, thru the MAF to turbo  
hose, I had the regulator set at 15 psi, but I've heard that  
regulators aren't so accurate at that low range. I realize this is  
well shy of 27, but I didn't dare pressurize the MAF to turbo hose  
any more, as it swelled like a 13 year old discovering his first  
Playboy Mag. Besides, I got tired of retrieving the plugs that I kept  
blowing out into the neighbors yard.

What's weird about the whole thing though, is that with my ECU, with  
the RS2 software, I'd get this cut out at about 27 psi, but with a  
Stock ECU with stock chips, I'd get the cut-out at about 13 psi.  
That's one of the puzzling pieces.

Thanks for the tip, I'll check further.

Regards,

-Manny

To what pressure did you test the intake plumbing?

Those Samcos are strong, if there's a leak, it could be effectively
sealed by their wall strength until you hit big boost numbers, then
dramatically/catastrophically blow open. If you tested to 27-ish PSI,
then this hypothesis is bunk. HTH.
