1988 Callaway clutch and flywheel

[sjandras]

Now that I have the car running 100%, it looks like the clutch is slipping under max boost. It runs around 2500 rpm at 65mph in 4th and as I get on it, I see 5k rpm before hitting 80 mph! The issue is, I see conflicting information on what is actually in these cars. Is the flywheel stock? Is the B2K clutch a standard L98 Centerforce? I've read that one person used a Spec Stage 2 clutch with good luck.

I'm hoping to get specifics from someone who has actually done this, does anyone have details to share?

I had Callaway install their single mass flywheel and clutch in my 1989 Callaway. Give Wayne a call and get the specs on it.

1988 had the 4+3, I'm hoping for recommendations for that application. I wish it was a ZF6 car!

Flywheel is stock.

Centerforce isn’t the best option due to the low end torque. CF clamps more at high rpm if I recall.

Thanks for the reply! I did reach out to my new best friend Wayne at Callaway this morning, and he confirmed 1988's were built with the stock one piece rear main seal flywheel and a Centerforce clutch. I'll start the diassembly process (again) in a few weeks and post pics here for reference.
