We all love the 8v because it's simple, strong, and has nice "twist" down low in the rev range. It's not as happy at high rpms, but we accept the limitation. Good news, however, is that reducing reciprocating parts mass sharpens response immediately. It puts less wear/tear on the cam bearings, too.
USRT believes that most MK3+ street car builders should choose this fixed-position option. Adjustable gears are best for engines with programmable engine management or CIS injection. This is because the modern ECUs often object to cam position changes. Meanwhile, mechanical injection sytems determine engine load via intake air mass. In most cases there is no ECU to upset in the first place.
"Double Your Pleasure": The Ultra Lightweight 8v cam sprocket works in both the cam and intermediate shaft positions. Mass is reduced nearly 66% compared to the OEM cam and intermediate sprockets. This is a huge advancement for our trusty 8v engines (both counterflow and crossflow).
Add lightweight lifters complete the low-mass = response concept. A light flywheel magnifies gains even further.
