Guys,
You may want to purchase the Feb 2001 issue of Volkswagen Driver. It contains an article about the haldex system and it's an interesting read.
I'll not reproduce the article here, but it does mention a test that Jim Curley performed, who runs Star Performance in Scotland (agents of AmD). They ran up a TT 225 on the 4wd rolling road, it had 165bhp at the wheels, and on full load the split was 135bhp front and 30bhp rear.
They go on to mention feeling the drive move from front to rear under certain conditions.
They even mention that because a control unit analyses the signals 'before it decides on the extent of slip which will be permitted in the coupling, there ought to be ways in which the split in drive can be adjusted. Perhaps this opens up a new area of fine-tuning for those models fitted with 4Motion [Haldex].' - Have they been reading this forum? We came up with that idea for "chipping" the Haldex ages ago!
Finally, they would like to hear from readers with 4Motion (Haldex) models, with reactions to the system. Now I know it's a VW mag, but there is nothing stoping you A3/S3'ers with "quattro" from writing in. But read the article first.
Cheers,
AL
