I am building either a 2.4 or a 2.7 type four and am wondering at what point do I start having to worry about needed something more than just the stock 2.0 liter type 4 sachs stock clutch? I know it probably depends on the cam and the amount headwork done but really can I get away with building a 2.7 with mild to fair amount of porting and abit larger valves? and obviously a sport cam. will I be seeing a lot of slippage? And Will something as simple as a particular plate help? thanks,Jo

I'm using a stock clutch, sachs 911 disc, on my 180hp 2.6L T4 (102X78mm)
I cut the fly pressure plate step .010 under spec. 911-901 trans with stock 914 /4 gearing, 914 flywheel, in a '67 VW bug. So far no slippage and I'm not gentle on it, but my engine is in a 400lbs lighter VW bug. I will say I'm totally at the limit for this set-up |
