The idea is to increase torque/hp in the lower rev range (lowering vtec engagement to like 4200 rpm) and not use all 9000 rpm to ease valvetrain abuse.

A higher boost pulley will yield more hp and tq throughout the powerband. I wouldn't worry about valvetrain abuse unless you're frequently going beyond 9000rpm on a stock head or sustained high rpm situations.
Try going the tuning route first. If you want more power and tq turn the boost way up

Great EMS tuning can accomplish this.

I'll post a dyno after my pulley gets here and I get done with my tuning.

Courage,
Both FF2Skip and I have experimented with a 3.25" Pulley on the Comptech Supercharger setup. Perhaps Skip will chime in with his results, however here are mine.
The car was tuned by the same individual who did my final setup (501whp low / 597whp high). Honestly, I was rather happy with the SC'er tune, even though I know it could have made a bit more power.
AEM EMS 1052U
AEM 3.5Bar Map
AEM FPR
RC Engineering 650cc Injectors
Comptech Supercharger w/ Aftercooler
ASP 3.25" Pulley
Spoon N1 Exhaust
JIC Test Pipe
HTG Clutch Kit
If my memory serves me correct, he did not alter my vtec engagement point at all.

[QUOTE=CourageOO7,Sep 24 2007, 10:27 PM]Guys,
I am thinking about getting a much smaller pulley on my CTSC (like 3.2 or 3.4 inch) on my stock HG and lowering my rev limiter to 8 or 8500 rpm.

I tried what you are talking about and it makes quite a highway monster.
I was maxed out at less than 9000 rpm.
The Vortech was making 2 psi at 3000 rpm, 5 psi at 5000 rpm, 12 psi at 8000 rpm and 15 psi at 9000 rpm with some over spinning. That equates roughly to an additional 35 rwhp at 3000 rpm, 85 rwhp at 5000 rpm, 200 rwhp at 8000 rpm and 250 rwhp at 9000.
I did have a bearing go on the supercharger after overspinning it for a few months.
Thanks for the heads up. I am not going too extreme with the boost. I just want a margin of safety while still building better lower end.
By the way, have you shipped my FPR? Sorry to ask you out here but I still can't PM you.
Best,
J
