Belt drive

[vector1]

svo and front of prod block should be the same. belt drives with the idler are suspect imo because of the idler bearing, some use ceramic but still wouldn't do it myself. i use a jesel, more $, but simple and reliable. if the belt breaks while on the road another won't help, i think these engines are interference type. after i got my engine up and running i didn't mess with the cam adjustment, would probably only come into play if you were serious and on a dyno. make sure you have a good strong cam, there is a bit of belt tension till things become accustomed to their new home. i used one on an aluminum block and the expansion stretched the belt and ruined the front cam bearing.

These really caught my eye several years ago when they hit the market and I was close to purchasing one. The reality is they are more of a development tool to allow for quick adjustments under controlled environments, they absorb more HP than a good sproket & chain. For a daily driver it would serve no real purpose. If it was on a drag race only car, it could be used as a tuning tool for different track or possibly climatic conditions, after refering to your data and log book so you knew what to expect for specific adjustments (having previously made anticipated changes on a dyno and noted resulting changes). Certainly a great conversation piece and the envy of those without but really can't see it serving any purpose on a daily driver. Like a belt setup on any OEM application in an "Interferance" engine, if the belt breaks, you don't get a second chance. JMO
