Best update for a Rover V8!

Posted by Unknown on 19th Jul 2017

I installed this flywheel about 2000 km ago and am VERY pleased with the result. The engine (Rover SD1 V8,4 barrel, headers, stock cam) gathers revs much faster and the car (a Triumph GT6) is MUCH quicker. There is no adverse effect on either idle or cruise. The only reason I gave it 4 stars instead of 5 is that I had to have the light flywheel drilled and pinned ($130) like the stock flywheel to center the stock clutch. The stock clutch is drilled for 3/8" bolts while the flywheel stock clutch pattern is drilled for 5/16". I understand this is not a problem with the uprated clutch covers which are drilled for 3/8 bolts that match 3/8" holes on the flywheel. I kept the stock clutch a I thought it would be lighter and not defeat the purpose of the light flywheel.
