Supercharged

imiller1974 · November 25, 2019

That's a great price. I bought mine from there, exactly one year ago. Paid $4600. Installed it right around Christmas after I got a tune from BlackBear. Took me about 8 hrs to do it, all outside in the driveway. A couple more adjustments from Blackbear has gotten it pretty good. It gets 19 mpg on the highway under 70 mph, about 18 mpg, pushing 80 mph, with 3.08 gears and stock size all terrain tires.

On another note, look at the passenger side of the supercharger. See that 1/2" port that's plugged? Run a hose from there over to the brake booster, and get rid of your vacuum pump. Works perfectly.

Ok interesting I have one thing I’m working on that I noticed. When your cruising and it’s not calling for boost. I notice when you feather the gas it surges a little. Almost like the bypass valve is not working as it should. Did you have anything like that at all. And I should have installed it myself. After a 3 week ordeal the place I used dropped a bolt in the head and blew the engine.

No, I don't have any surging. Still shifts like sh!t sometimes, is the only issue I have.

Yea my trans shifted like shit before the supercharger to. maybe it’s a tune issue or something. I will call the installer tomm see what they say.

I think I figured out what it is if you get a chance can you look or tell me if you installed the bypass restrictor valve. I just looked mine is not there.

So you're saying the solution to the failing vacuum pump/brakes is to buy a supercharger? Nice, may be the excuse many of us are looking for to tell the wife.

Yes, I have a bypass restrictor. It's a .023 nitrous/fuel pill/nozzle. I've tried a .030, but it came on boost too fast, so I went back to the .023.
