at RG, we've been using Conti on all types of customer cars for years with ZERO failures!
from stock to HIGH HP builds, we've havent had a problem with them. this includes a number of customers 500+whp cars and the 1109whp supra we just tuned.
Brett, i think yan's scenario could come up with a few conclusions but thats a bit off topic. i believe yan was driving under normal conditions when his engine failed, and resulting in a damaged belt (conti).
i think no matter the brand, if a belt "fails" its usually the result of another component failing (a tensioner, an oil pump, ect, ect) or improper install or is someone was foolish and soaked their belt in oils.
would we all be saying Greddy belts are junk if someone happened to be running one when their engine failed???
probably not lol
