Torture testing Passon Performance Products
ummm I just ran a check of my log book

1000 track miles on the Passon alum case 4 sp overdrive and 750 track miles of Passon alum case 2.66 1st gear 4 speed. Another 750 track miles of an iron case 2.66 1st gear Passon 4 speed

Speeds range between 70-130 mph, time under duress 50 minutes per session 4x/day/2 days, no problems, no temp issues, no issues period, no vibration, just lots of fun.

Track is 3.4 miles
1000 miles is 294 laps...
750 miles is 221 laps

Everyone please be patient with the process of creating the the best 5 speed transmissions. Jamie will not release the beast until it's 101 percent right.

Unlike others in the business the Passon products work because:
Quality goes in before the name goes on.

Quality and integrity will be remembered long after the price is forgotten.
