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.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment

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.

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.98 Camaro-Powerdyne S/C, Bilstein, Mtx, Rk Sport, B&M, Jet chips, Texas Speed, G2, BMR, etc etcComment

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...[ full bolt on\'s and blown.]<br />[formerly known as naptown]<br />[just know that im teh man ]Comment

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.98 Camaro-Powerdyne S/C, Bilstein, Mtx, Rk Sport, B&M, Jet chips, Texas Speed, G2, BMR, etc etcComment

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.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment

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.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment

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?98 Camaro-Powerdyne S/C, Bilstein, Mtx, Rk Sport, B&M, Jet chips, Texas Speed, G2, BMR, etc etcComment

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.\'98 A4 Camaro v6->v8 conversion, and STS kit next<br />v6: 13.6 Powerdyne, 13.2 150 shot, 13.8 120 shot, 14.3 85 shot, 15.7 stock<br />v8(na): 12.18@113, 392rwhp<br />Moderator on <a href=\"http://www.mtfba.org\" target=\"_blank\">www.mtfba.org</a> and <a href=\"http://www.frrax.com\" target=\"_blank\">www.frrax.com</a> (Road Race & Autocross)<br /><a href=\"http://community.webshots.com/user/johnduncan10\" target=\"_blank\">Car pics</a>, <a href=\"http://www.trscca.com\" target=\"_blank\">TN Region SCCA</a>Comment
