Personally I think the DXD clutch I have now will be just fine, maybe get the 6 puck clutch from Southbend to hold more power, but running a twin disk is going overboard in my opinion.
Also this person thinks that all and every 7 bolt that makes power will crank walk no matter what. So if its going to get CW no matter what then why should I get a twin disk to slow the process down? I think thats a broad statement for the people that have made a lot of power on 7 bolts and yet they havent crank walked. Any opinions?
Personally if every 7 bolt walked then there would be recalls and no one would have one in their car yet start adding mods so they make power. There are a few people that have stuck a lot of money into their car and run 7 bolts. Look at Shane, he's making great power on his 7 bolt and he has little to nothing in it for machining. Brian made good power on his stock 7 bolt before it crank walked but it was stock so I can see why it happened. So I dont understand how that statement can be correct.
I want to hear some opinions first before I start this project. Am I wasting my time?
