jim21070 2 Posted July 27, 2006 A straight-cut gearset is able to handle more torque. Hardly a problem with a Pug BE3 box The price you pay is noise. Listen to how any 'box whines in reverse. Imagine driving along in any forward gear listening to such a racket! Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted July 28, 2006 If you've ever driven or been in an original Mini that is a step closer to the noise of a straight cut gearbox. Personally its not thatbad, a mate used to have a Mini with a straight cut Jack Knight gearset & drop gears, that made some noise but it was nice imo (especially at 8k). Certainly hasn't put me off the idea anyway. Staright cut gears don't sap as much power as helical ones, are stronger but downsides are the noise. Graham.
