I am considering purchasing a Procharger supercharger for my 91' TA.

Any good or bad experiences???

Also, for the difference of $600 in cost, which unit is better? The P-1SC or the D-1SC?

Any problems with the SC units??

Willie, you out there???

Thanks.

 

Any good or bad experiences???

Only good. Shaved slightly over two seconds to date. I've owned the D1SC for almost 18 months with no problems.

Also, for the difference of $600 in cost, which unit is better? The P-1SC or the D-1SC?

The P1SC has a more linear boost curve. The D1SC has more on the top end. I don't think either is "better" than the other in terms of quality. The one you select is based on how your engine is built, I suppose. On a stock or near stock engine, I'd go with the P1SC. If you've built your engine to rev to the moon like I have (6200 rpm shift point), go with the D1SC.

Any problems with the SC units??

None so far. My only concern is the lack of airflow to the radiator due to the intercooler. This "problem" would be worse on a Firebird because all it's air must come from below -- no openings in the nose. If you live in a cooler climate, it's not a concern. If you live in a hot climate (as do I), your engine will run warmer all the time. Even with a Camaro with "grill" openings, I've done everything I can think of to keep airflow moving through the radiator.

 

Thanks for the info Willie.

I would be using the supercharger on a stock engine with intake and exhaust modifications. So the P-1SC should work fine.

From what I understand the "sc" models use the self - lubricated compressor. Do you need to do anything special for maintenance of these units?

Since I would be using this on a Trans Am and I live in Louisiana I may have cooling problems????

Any advise?

Why is your RPM band so high?? I mean how did you set it up for this?

Thanks again.

Read my article first:

https://www.thirdgen.org/newdesign/tech/cool.shtml

It talks primarily about how to get your fans to turn on sooner and/or on command. Use a 160 t-stat with small "bypass" holes drilled into the body. My article discusses this. Since you live in Louisiana where constant cold temps are not an issue, do not use coolant. Instead, use a mix of distilled water and Redline Water Wetter. Add to that a new water pump lubricant. Prestone sells one. I live in the desert Southwest. I had to add two pusher fans.

Why is your RPM band so high?? I mean how did you set it up for this?

Peak torque and horsepower are determined primarily by camshaft specs, which in turn determine redline. I have a custom ground Crane cam with useable range from 2,000 to 5,700 rpm. Desktop Dyno/Dragster has calculated that I need to shift at maximum rpm. I have experimented some with shift points at the track. I run quicker by manually shifting my 700R4 at 6,200 rpm vs. letting the transmission shift at 5,300 rpm.
