Just ordered a WCC supercharger system for my 1999 auto. I would like some advise on the differential and the Torque converter upgrade needed.

Regards

 

If you car is stock (stock displacement and heads) and you set up the supercharger reasonably, by which I mean at no more than about 465-475 RWHP (any more will quickly trash the engine), and you will not really abuse the car with stupid stunts, then you really don't need to upgrade anything in the driveline except the rear tires and wheels. I would recommend at least 315 section tires on wider wheels (they will fit) or getting a LIngenfelter mini-tub kit and going to 345 section tires. Ecklers sells upgrade diff and trans components if you want to go that route, but you shouldn't need it unless you go beyond what the stock engine can take itself.

 

I think I'd still at least throw on a diff AND tranny brace though. Cheap insurance.

 

You really need to go to www.corvettegarage.com and get these two things. The bracer and the output shaft. I just ordered them today, and here is the info and prices for them both. I hope this helps.

1 x Dynotech Engineering DTE Differential Strut Brace for C5 and Z06 Corvette (dte-c5strut) = $379.95

1 x Lingenfelter LPE Heavy Duty Differential Output Shaft for C5 Corvette (lpehdshaft) = $299.00

 

If i upgrade the Diff, what ratio would u recommend with the T trim Vortech supercharger.
