Go ahead and calculate it into the budget now, my friend. I have a T-78 and burnt mine out on the dyno. I didn't even have upgraded fuel and burnt it at 463.6 rwhp. If you're looking to make any kind of HP, upgrade your clutch in some way. Whichever way may that may suit you.

It wasn't on the first pull, it took a while, but the stock clutch does have it's limitations. Better safe than sorry, though. I ran into a Firehawk a few seconds ago and was glad to have the insurance of a clutch that can handle the hp. Before I changed the clutch, it was soft going into gears. It's just one of those things that after a certain point become a bottleneck.

just coincident that the clutch burnt out on the dyno or mean it's time to be replaced,,...

anyway, you won't get real number when you have OEM cluth, because the stock mkiv clutch only handle 14 psi which around 500rhp, the number u got won't be correct!

but that's a good thread to talk about, because i almost forgot about the clutch on for my car! thanks!:p

The OEM clutch was coming up on two years old, and I and made mulitple hard launches on it. The disc itself had plenty of "meat" left on it but it was completely glazed over. It was an awful sound when that thing slipped at 5500 rpm.

sound like you have a problem like mine. you lost the clutch while tuning. now what? do you tune it with a new clutch with out the break in? my mistake was getting a new turbo with new clutch and with new brembos all at the same time. no tuning and no break in period for anything. the bad part is that i have the new F-CON S and its needs to be tuned right off the bat. program is blank. so i am having problems with the tuning and no break in period with anything. i should of bought my turbo last then the other stuff so at least i can start my car. righ tnow my car doesnt even start. i might ruin a new RPS clutch on the dyno just to get the program started. sucks!!

Hmmm...that is a good one. A break in period is definitely needed with the clutch. It'd last about 2 days run hard with no break in. I'm sure their are a lot of people that will say just run it new, but that period is very important. So your car won't even start? I didconnected my battery for a while the other night and for some reason I lost the low RPM throttle settings on my S-AFC. The car started fine but it didn't idle at all. I finally took away 9% fuel and it worked fine. But I remembered that all the other RPM settings were at zero when I got it tuned. I guess that means that you only need the fuel tuning at high throttle positions. If you can get you car to start and drive it around in town for 800 miles you're in there.

if your going to get a T78 you might as well shell out the doe now and get the clutch broken in and get use to the difference. Your oem will not last long with a single. ;)
