  1. For use on the track, fix the oil pressure problem these cars have. A 2qt deep sump isn’t enough though. Check your oil pressure on a 270 degree highway on ramp with rpms at or above 3400 rpm and 15 min of highway driving speeds immediately beforehand. You will see what I mean.
  2. Mark, Put a oil pressure sensor in a oil filter sandwich plate - if you have a screw-in oil filter adapter. In order to achieve good rpm and oil pressure relationships - the oil pressure readings need minimal lag.. putting the sensor near the filter will put it the closest to the pump. Then find a 270 degree (3/4 circle) highway on-ramp, with continuous constant radius curvature..your Rpms at 3400 rpm or above, 15 min or highway driving immediately before hand, and hard cornering then look at your data. I can’t wait to see your response once you see the data..
  3. Loren, What parts would I need for a ROW Sports setup for a my02 c2, manual, cab? Currently has standard USA suspension.
  4. Could you shoot a video with your smart phone and show us the front wheel spinning on snow or ice (or anyone else)?
  5. You're right, and the Haldex system would have been the right technology, a good match for the 911s layout... Which is now used by cars like the Bugatti Veyron, etc.. It would require inputs from steering angle sensor, a gear selection sensor , parking brake switch, brake pressure sensor, or at least a brake light switch.
  6. After further review, I think Porsche intentionally chose a relatively weak viscous coupler (compared to the BMWs and Volvos above), to avoid understeer. The stronger the link is between the front and rear driving wheels (i.e. the stronger that viscous coupler is), the harder it is to turn (esp. on pavement, will increase understeer). Considering Porsche's customers probably find street/track performance more important than going through deep snow and ice, compared to volvo and bmw owners, and since 911's are decent in the snow with their engine on top of the driving wheels, and p-car owners p
  7. there are a few videos on the 996 4wd system - which don't look very impressive. watch how the front tires of don't spin: porsche 996 turbo - 996 c4s - another 996 c4s - Re: the delay associated with the system in the c4 (due to the viscous clutch (VC) fluid), there are plenty of videos showing there really is very little delay (below). I think either: a) Porsche's choice for their 996 Viscous Clutch was designed to transfer very little torque, or b) there are a lot of worn out VC's in 996's out there. Here's a few videos of people testing the functionality of their AWD
