Still have the control center?
charlie what is a pevr and turbo control module and what years interchange if you still need going on vacation for a week PHX, LA, Vages other half gets pool I get to go parts hunting lot of G body in PHX and LA will take a look if you can give info can't tell you how many 4barrels I've passed up Have a buick only parts yard in Phx if it needed they have it
if they have a pevr i need one.
The PECV stands for power enrichment control valve and it's used with the 78-80 cars. What it does is to allow the primary metering power valve to open at 3 lbs of boost so the system doesn't run lean and have detonation issues. A conventional carb relies on a vaccum signal to meter the fuel into the carb and will lean out under deceration. The turbo carb will stay rich under deceration until a safe pressure level has been acheived. The factory system uses the PECV valve ,set at 3 psi, to acheive this.
The carb isn't a standard Q-jet either. It has an isolated power valve which is controled by the PECV valve. A standard Q-jet can be made to work but need some adaptation to do so. The way to identify the correct one is that there is a port directly under the fuel inlet which is the isolated power valve. With out this particular carb the engine signal will be from vaccum and under decelation the engine will go lean and detonate.
The interchangability is a very narrow one unfortunatley. The 78-80 carbs. the 78-80 PECV valves are really the only things that interchange. This is only for the Buick engines and only for those years. As far as the turbo control center you have 2 different ones and not a lot of interchangablity on them either. The 78-79 requires the 78-79 distributor and control box and the 80 requires the same or it won't work right. Good luck finding one and hopefully you find several. They're very scarce and I finally got one of them myself, after 4 years of looking.:redface:
78-80 pevr pics please
anybody got pic's of this stuff? PEVR, PECV, control module
PEVR vs PECV are they different or the same?
what are these thing worth so I have some Ideal whether to get
Speedway buick will most likely have them if anyone does all they carry is buicks I bet they have 50 83 -87 T and GNs alone
Carb is for turbos only right? anybody got a part number
78 and 83 in phx no rust body part in az
