Anyone using the spec twin disk clutch what do you think the price is great on these.

 

I know that Hal from Injected has one, maybe he will chime in

 

waiting on chime........

 

I have heard first hand poor review on the Spec twin disc slipping at higher power (650+) even though it is rated for 1200tq or something.

As far as I know, I am one of two people using a prototype for higher power from them. I haven't had time to put my car on the dyno yet, but the other person I know is making 700-800+whp DD and has made a number of track passes without any signs of slip. Once mine is tuned and I have some miles on it I will post a review thread. Sorry I can't shed any more light on this right now.

 

Decent chime

 

Ive got one on my Z because I was anticipating on boost this year, but I sold it before I did. The pedal pressure is like stock, very similar to the JWT feel, and the engagement is a lot lower than stock. Ive got the PT version and the chatter is there up to about 22-2500 rpms but that is expected with a lightweight FW. SGP recommended it to me since they put down many 600rwhp+ pulls on one of their customers and there was no sign of slipping and thats what I planned on when I bought it. I highly recommend it!!!

 

i have the twin disk.. it is very driveable and street and supposed to hold 1000+ tq
i am only making in excess of 400 right now but i do plan on getting more in the future. it is alot easier to drive than a single puck style clutch
however from 1500-2100 it makes the standard flywheel/drivetrain noise nothing crazy but i like it...
