Hello everyone,
What do you think the most likely weak links will be for the ST between 700 and 800 lb feet of torque? Does using the Torsen differential as a preventative measure for high torque (700+) make sense or are there still too many unknowns for this to be a rational decision? Is it correct to assume that the Torsen differential will hold significantly more torque than the open differential for road racing (no launches)?
The Torsen differential from the timerbline seems to be working well for several ST's but not flawlessly. Some ST owners, who made the swap, stated that they had increased tire noise during turns which makes it seem that the AWD system is making the transfer case go into a 4H setting for some reason. The Torsen diff seems like it would be able to handle much more power than the open diff, but no one has tested it on a high performance ST yet. One member mentioned that the Torsen diff would be great for road racing, but bad for launches.
Kathy, the current 1/4 mile record holder for the ST, is still tuned for 690 lb ft of torque on the street and that's likely not going to change soon since a driveshaft failure just occurred with HSF's ST, which is running significantly less torque. Once a custom driveshaft is on the market, we'll likely see higher torque numbers.
Attached is the last dyno pull from the ST. For now, no launches are planned for at least a year after it's built, but I was hoping to keep it out of the shop for as long as possible once finished.
