Any solid FMIC set ups recommended? I'd like an intercooler I can grow into as once this is sorted out an F1 swap is going to happen.

A 3.40 pulley should get you a lot more boost than what you are seeing. The Aster bracket will take care of your problems. No need for modified pulleys with an Aster bracket, they tend to chew up belts anyway.

How much boost the blower can produce depends on many variables.
* Cubic inch. The larger the engine the less boost it will make with a supercharger.
* Headers and exhaust. A better flowing system will produce less boost, requires a smaller pulley to regain the loss in boost. Ultimately though, more power will be gained.
* Camshaft and heads. A camshaft with some overlap will leak out some boost through the valves. Better flowing heads react a lot like a better flowing exhaust system.
* Altitude. Elevation plays a big part in how much boost is produced. Those people living in the higher elevations have to spin the blower harder to see boost.
* Condition of engine. An engine with real good sealing rings will ultimately produce more boost than one with worn rings.
* Rpm. An engine that is spun up higher in the rpm range will normally produce more boost.

To determine the impeller speed, the following formula is used:

Maximum impeller speed = crankshaft pulley diameter (N1) divided by supercharger pulley diameter (N2),multiplied by the step-up ratio (4.10 for the P-series/D series - 5.40 for the F series), multiplied by engine rpm at redline.

The D-1SC is good for 62,000 rpm.

The ProCharger front mount intercooler kit is a great way to go. If you want to see a copy of the front mount installation instructions, send me an e-mail asking for them. Thanks. Bob

at blindly throwing compression at it to fix the problem. There isn't a thing in the world wrong with 9.1:1 Personally I'd like to see it closer to 9.5:1 but "compression" defiantly isn't your problem.

In defense of oscs it seemed like the OP was not getting the message as he kept bringing it up.

That wasn't directed towards him. It was directed towards the people that suggested he do so.

What's wrong with bringing up the compression anyway? My tuner mentioned it should have been higher (he said that was why it fell short of expectations in the first place) and I asked if 10:1 would be okay to run with an F1 series blower. That seems like a pretty legit question. I'm going to tighten the belt a bit and see if I can get some more boost out of it for now. It seemed pretty tight already but it's hard to tell from up top.

Anyone have any cost effective front mount ideas? The Procharger upgrade seems a bit pricey for an intercooler and some piping.

Nothing is wrong with bringing it up or utilizing compression.

Your issue right now is you need to fix the belt slippage ans get a better intercooler setup though. With a 3.4 you should be making a lot more power.

If you don't want the Procharger FMIC kit, you can replicate it with a decent intercooler, and piping that you source and modify yourself. Lot's of people have done that, including me.

I believe his compression is unnecessarily low, but it's not what's leaving 100+hp on the table.

Thanks Alchemist. I can run some tubing and mount an intercooler. Any suggestions on size or brand?

Honestly if you are doing the FMIC the Procharger setup they make is a great piece, and not terrible expensive.

Give us a call and we will be glad to help out on your tensioner, FMIC and any other needs!

I'll throw in my .02 since I have some experience along these lines. My setup used to be a D1SC and I made 700 RWHP. This was on 93 octane and only 8.8:1 CR.

Look for dust on your belt. If you run your finger along the inside of the belt you'll see if you've got dust or not. Belt slippage will rob you. I also recommend a larger metal inlet elbow and a larger air filter. Those can make a HUGE difference also.

Can upping the CR help? Yes, but like others have chimed in already, that's not your problem. My 700 RWHP was on my ancient LT1 car. Your LS should easily be able to make the same. I ran a cheap EBay FMIC, and was seeing 15#'s of boost with a 3.4 blower pulley.

I didn't find any black dust or physical signs of belt slip. The pulleys are clean which was a bit misleading. I already ordered the Aster bracket, an intercooler and some piping/clamps to get everything going. I have a new K&N filter (bigger filter too) on the intake side but I'll ditch the accordion style tube that came with it for something better.

Thanks for all the help guys
