The largest pulley on the bottom is the lower.
Dumb question, which pulley is the lower? I noticed this today
Is that bad? I'm not new to modifying cars but this is my first modified supercharged one. I had a lightning but I didn't do anything to it except exhaust.Lower pulley with stock idlers. Lol
That’s the old Billet Flow picture Shane. Thanks, I’d lost it.View attachment 1598496
For God's sake get rid of those stock idlers tomorrow. Loved Metco
This was my lower Idler after a 3rd gear pull at 17lbs of boost.

Oh yeah...it was a catchy picture with BF but I hated them...looked like butt instantly. Metco is the route...atleast in my opinion.That’s the old Billet Flow picture Shane. Thanks, I’d lost it.
You basically said everything I was thinking. I feel like they left the tail pipes for the look but put in dumps. I have a BBK catted midpipe coming for the long tubes and a magnaflow catback coming as well. Any idea what injectors are yellow topped? And I was looking at plenums and TB's to compare this morning and what I have looks just like the Accufab. When I pull the plugs this weekend I will use a borescope to check the pistons. I've been driving the car for a few days now and it only starts to backfire and miss at full throttle. Otherwise it pulls hard at part or 3/4 throttle. It idles smooth but with the exhaust the way it is it is hard to hear much of anything when moving. There is a pulley/belt chirp that vlive narrowed down to the idler above the tensioner so I might as well replace all idlers. I will use a micrometer to measure the upper, lower, and aux idler pulley so I can see what I have. Thanks for the help.Plenty of folks here with gobs more knowledge than me, but reading your symptoms and seeing some pics of the car has made me uneasy.
Other things for consideration that may or may not be noteworthy (I'm not an expert here):
-I'd take a peek in the cylinders while you're swapping plugs just for the peace of mind.
-Overall, she seems a little dirty. It's clear she's been around a lot of moisture given all the rusty bolts, exhaust, and various other parts/pieces. The aftermarket pulleys don't even have any shine left to them. Lack of basic TLC perhaps.
-Speaking of pulleys, who does a blower pulley, crank pulley, injectors, SBTB, goes through the arduous task of long tubes, and (from the looks of it) still runs the stock heat exchanger?
-And speaking of exhaust work, is that a "custom" turn down/dump while still retaining the rest of the tailpipe? It all feels fishy and half-assed to me.
I don't mean to sound all doom and gloom over here or to rank on the car. Just noticed a few things that made me scratch my head and couldn't keep it to myself.
I'll check there, thanks.OP don't get down on the car. Give it some good TLC, a little goes along way.
I'd suggest like others have mentioned and get it tuned before anymore pulls are made, stay out of boost until then.
Did you pull the trunk liner on the drivers side to see if there is any upgraded fuel components, such as a boost-a-pump? That's where I had mine.
