I have a modified 325is. <br>Engine modification consist of:<br>JC chip<br>K&N filter<br>Big Bore Throttle body<br>8mm spark plug wires<br>Schrick cam<p>And recently installed a supercharger, should I set it at 32 as previously set or increase the gap with a supercharger. Any help is appreciated. Thanks

For the spark to jump the gap, it takes more energy. I would alter the gap only if you have changed your coil for a stronger one or with a Jacob.<p>Higher compression also alters the way the spark travels between electrodes. You should ask the manufacturer of your supercharger kit what the best is.<p>I would be absolutly delighted to have your commenys on that supercharger. Difficuylty of installation, power and day to day driving.<p>Lee

It's on the car for about 4 days now, and I have to say that it's the best bang for the money. I think roughly it has about 280+ hp with all the modification I did. On a daily to daily driving is superb, the car has too much power, but can't stop quickly. I need to upgrades the brakes. The boost is at 6psi. It's used, but does the job. I installed it myself. The only cons about it, is that it makes a humming sound at idle. But, worth it. My advise - if you can get a hand on one of this supercharger. Buy it.

Thanks for the info. Can you tell us what Trim is the supercharger. Is this an S trim? What about the pulleys and brackets.<p>Very excited Lee

I believe it's a "S" Trim and gear driven.

I could be wrong!! In any event, the car has not been dyno tested. This is just an estimate. It's sure feel like 280+ hp. I found out that the guy I bought it from bought it from ESS Tuning.<p>kevin
