awsome, i knew i was right...

Glad to hear it's running good now. [img]smile.gif[/img]

One more tip - once in a while, maybe once a month or so - the engine would want to idle high (like 2500 rpms) when I'd come to stop. Even if I put it in neutral.

If I'd turn the car off, then back on, it would be fine again. I could do that while the car was still rolling in neutral, so I wouldn't even have to come to a stop to correct it.

I think it was something flaky with my pcm, and with it being an automatic too. So, just in case you run into that situation in a month or so with the maf unplugged.

Thanks for the clarification on your old system, John. Maybe I forgot you were getting as much as 12 psi with that rig. It that case it could be scary to go with stock injectors and pump.

Glad to hear your car is up and running 1black98.

update?

Alright soo I am starting to get a little mad with the guy in at the shop. He has had to car 2 weeks now and has only found that he thinks my car needs a higher output fuel pump. I think i could have let the car sit for two weeks and decided that for myself. Alls i wanted him to do was look over everything and make sure everything was running okay. Hopefully though i will get it back tomorrow though so I dont have to deal with it anymore. By the way, I am thinking about gettin a blow off valve and was wondering if any universal valve will work.

Hmm, the FMU should be enough for running 6psi...

I bought a fuel pump because I was going to make it run 12psi.

You really need to get some headers and full exhaust system...

SO now it seems as though a new problem has arose. I heard a rattling noise coming from somewhere around the supercharger. Well i thought it was the Tensioner pulley so i swapped it out with another one. Well it was still there after that and under closer inspection i found that it was coming from the supercharger and/or its pulley. It rattles through out the whole rpm range too. Im not quite sure what it is though.

[John_D.]

It may be the pulley bolt. I had a rattling sound one time, was sure it was the bearings, ordered a rebuild kit, only to find out the pulley was just a little loose... The keyway on that pulley is just a little big, and if the bolt isn't really tight, it lets the pulley load and unload on the shaft. I don't remember for sure if I put locktite on the bolt threads again, the last time I had it off. Or if you (or the in-between owner...) have had it off, then you may have to put some blue locktite on the bolt threads again and let it set up for 24 hours.
I never did find a torque spec for that bolt, but I was snugging it up to 35 ft-lbs.

[John_D.]

It's also got 1 or 2 spacers behind the pulley, you need to keep those on there to keep the alignment right. That was the main slippage problem with it when I first got it, the pulley wasn't quite lined up with the rest of the pulleys.

[1black98]

Alright thanks. I will try and see if can tightening it up some. Im guessing it will be easiest to tighten if i take the supercharger off and do it that way right? Also i was wondering about a BOV. Will any universal bov work on my system or should i not mess with it?

[John_D.]

I think it would be easier to get a torque wrench on it, with it on a bench. Plus you don't have to worry about the spacers falling out. You'll need a strap wrench to hold the pulley while you tighten the bolt. Harbor Freight, Big Lots, etc. have rubber strap wrenches pretty reasonable.

I haven't fooled with a BOV yet myself. I may put one on my turbo eventually. But those will "stall", where a blower can't really stall with a belt still turning it. Also BOV's help more on a manual tranny than they do on an automatic.

Problem solved. Its running rattle free and good now. Thanks for the input. Much apreciated.

Glad to hear that. What did you find?

Now go burn some rubber [img]graemlins/burnout.gif[/img]
