hey guys, I noticed that some of you with the late model L98's have removed the frisbee and some have not, just wondering if it's worth doing on the 89?
any negative effects go along with removing it?

:flag From Canada but I support your troops, hope there back soon. :chevy

Hey, I'm just down from you on Interstate 29 in Sioux Falls, SD. :thumbs:

Anyway, I took mine off when I replaced my waterpump on my 89. They claim the motor spins up a bit quicker. If nothing else it cleans up the front of the motor. No harm in taking it off, it's makes a good door stop. :cheers:

It weighs almost 9lbs. so it could only help free up the motor a little. I did it with no ill effects. (Took about 15 min.)

Could someone please tell me what "the frisbee" is? There's a pic of my L98 at http://jsa007.tripod.com so maybe someone could point it out to me? And why would I want to remove it? Is it some sort of safety equip.?

Thanks, and sorry about the hijack

:cheers:

Can't see the frisbee on your pic. But if you look at the front of the engine, it is bolted to the pully which is bolted to the waterpump, it's held on with 4 bolts. The frisbee is about 10 inches in diameter and wieghs about 10 lbs. I think the years were 87-90. The original purpose was to keep engine vibrations down when the A/C was on, it's not a safety device. Several Corvette experts say that it serves no purpose and can be removed without causing harm. It's thought that removing the frisbee reduces parasitic loss causing the engine to wind up quicker, resulting in a little more power. :thumbs:

Thanks for the info! I just double checked, and there's definitely no frisbee on my '85. Especially since they didnt start till 87 :lol:

Check that topic with a pic of the early "frisbee" on my site; you'll note that I got the word from "Mr Corvette", Gordon Killebrew himself at Carlisle, PA.

It only came on '88-'91 L98s to dampen the effect of the A/C compressor kicking on/off after the compressor and brackets were changed from the '87 style.

As it turns out it wasn't realy necessary and robs about 10hp from your engine.

Hey!

Here's the address of a site someone posted about the frisbee removal(http://www.geocities.com/jgkov/Frisbee.html). I haven't done it on mine yet. The bolts are really tight. Apparently liquid wrench helps. I might try it this weekend. Good luck.

Worth doing? Hell, it won't hurt! I hear it adds 10 HP. :auto:
