Grant goes by weed burner here on the forum. I haven't seen him in quite some time out here but I've talked to him plenty of times and he's real easy going. If you look up clutchtamer.com or something like that you'll see all the articles.
I put one in my car just about the time I stopped drag racing.. I guess you really never stop and not to say I won't be out there again but I've just moved on to other things...
The reading in the articles get pretty complicated but more so it's just trying to get that half a disc of slip or quarter disc of slip at the hit. You're trying to not shock the tires and get them to burn but you're also not trying to shock your drivetrain as well it's that perfect slip of the clutch that you're looking for...
Being able to dial that in right at your dash is a pretty cool option...
Having a pre-adjusted slippage in your clutch or having to go under the car and adjust it seems like a bit too much work to me...
