LT1 style T56 clutch upgrade
 

Hey guys,

I upgraded my turbo earlier this year and with the new added power I will be looking to upgrade the clutch and maybe flywheel. I should be right around 800 WHP with a conservative tune on E85. Anything past that I might be at the limit of the stock block. I would also add another Walbro 450 LPH pump in the tank if I do push it. I currently use a 6 year old Centerforce Dual Friction clutch which I caught slipping in 4th gear in full boost. Do you guys have any recommendations or suggestions for a clutch set-up? See sig for most of the combo. Much appreciated.

The market for the Valeo pull pressure plate style setup isn't gaining ground. It's going to have stage 1-3 from many. If you weren't hitting it until on a roll, you might do okay there for a while. Else, McLeod makes a lot of custom product, but I've seen way too many totally capable twins get set up wrong and be a waste of time. Personally, at that level, I'd talk to someone who could line one aggressively (You'll wear down the pressure plate and flywheel, but the disc won't die.) and try the stock single 11" size out. Lots of places say they can add some pressure to the flexplate, but I haven't had enough of the Valeo setups re-lined / serviced to speak to that.

Thanks for the input. We just had our first snowfall so this may not happen until spring.
