I have the Brookhouse lightweight flywheel which was bought 10 years ago. I believe the weight to be 4.5 kg ( but i never put this on a set of scales!)
For me, in my 1800S with a B20 engine, there has really been only upside with having it. With reduced lag/weight for the engine having to turn the flywheel, the acceleration increased giving the car more 'zip'. As the driver I slightly adjust my driving style,( for me now unconsciously). To give you an example, each year when I have my car MOT (optional) the testers stall the car unless I specifically tell them to use extra throttle as they engage the clutch from standstill. I usually forget and then hear the tester stall the car! The only other issue I note is to keep the engine revs up on a steep hill, as the lacks the inertia of a regular weight flywheel. But that is a question of just changing down in the gears. No hardship! |
