Looking for speculation - why plumb out a BPC? Posted by Ari [Email] (#2847) [Profile/Gallery] (more from Ari) on Wed, 18 Aug 2004 17:20:47 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I was looking at a '97 9K CSE today. It felt a bit slow off the line, and the boost guage never made it past 12:00. I checked under the hood, and the BPC had been plumbed out - the R side was still tied to the input to the turbo, but the C and W lines were plumbed together with what looked like a one-way valve. Of course, that explained the lack of boost.
I was entertained by the dealer, which claimed that device with three ports (and only one used), mounted on the radiator, was really the overboost fuel cutoff switch. On a Trionic????
I'm looking for ideas as to why this would be done. About all I can come up with is a failed BPC that was causing an overboost situation. Because just about any other failure I can come up with leaves you with Base Boost, which is what they've got now.
I'm interested in the car, and if it's just a bad BPC, no big deal. But I'm looking for ideas as to something else may be up that I'm missing.
thoughts?
TIA!
