Default supercharger help

Does anyone know of a twin screw supercharger system for an 87 L98. Spoke with the folks at Whipple. They do not have a system for my application.

Seems like some of the companies only have systems starting with the 1988.

Thanks :confused:

Carroll Supercharging Company is what you want: http://www.carrollsupercharging.com/ . You should go with a centrifugal design blower...much more efficient than ANY other design (for automotive purposes). Good Luck! :chevy

Thanks for the info. I have looked into the Carroll website. Might be my only choice. Really wanted the Whipple type more for the aesthetics and low end torque. Gives a pretty good HP increase, and no lag. Oh well :sad: If something else doesn't crop up guess I'll be lookin' into the Carroll unit anyway.
Thanks again for the information. :cheers:

Why does it work for an 88 and not an 87?

Beats the heck outta me :confused: That was all I saw on the Whipple web site...started at 1988 and went up from there. The rep from Whipple said 1) they do not make a set up for my application citing a too high compression ratio, and
2) They do not do custom applications :crazy:
Oh well...have spent the last hour or so looking over the Carroll site. Looks like it may be my best bet for all around performance/drivability. Just kinda wanted the "blower" look...asthetics.. :D

Isn't it your compression ratio 9 or less with iron heads? Later cars switched to aluminum heads and ran even higher (my 89 had 9.5:1).

I'd check back with their tech people- If that's the only issue, I don't see why can't run a Whipple with 5-6 psi of boost. ATI makes intercooled kits and lists the same one for all 85-91 L98 vettes: www.procharger.com

But if your CR is too high for a Whipple, it's too high for any centrifugal blower also...

Some of the '86 corvettes had aluminum heads. 87+ had aluminum.

STREETNIGHT,
Go with centrifugal, much easier of an install and the efficiency is MUCH better. Whichever you choose, be sure to get an air/air intercooler for it to get a little more out of the boost (colder intake allows you to run a little more boost).
