Hi Everyone. I have been tuning the Jalpa and have a Dyno session scheduled for Thursday. I put a couple of bungs in and am using a wideband o2 sensor for mixture. I went to do a 0-60 pass and a 0 to 100 pass today. The problem I have from a standing start is that the clutch slips and it will not hold all the torque the engine is generating. I have 335/17 tires with a soft compound so they really stick. When I floor it the clutch slips for about 2 seconds as I start moving. I bought a sachs performance clutch but am using the stock pressure plate. It is obviously inadequate. I hit 0 to 80 in 10 seconds until a car pulled out in front of me.(Losing 2 seconds for clutch slip)Probably would have taken 3 or 4 more seconds to hit 100. It pulls really hard at higher speed. What has everyone done to improve the clutch hold? Does anyone make a better pressure plate or can rebuild one to make it better.
