jonnyboyo 0 Posted April 19, 2007 Will one of these lighter flywheels be of benefit on a 1.8 valver with 124k? And how much are they? They sound tempting :) Quote Share this post Link to post Share on other sites
iow_corrado_g60 0 Posted April 19, 2007 leon defo worth it on the G matey! instead of buying new i'd get a standard g60 one or yours if you can be without it and send it of to be lightened dont go to light though as it will cause engine to stall!

Yandards 0 Posted April 21, 2007 To add a different perspective on this. Flywheels act as a store of energy, the heavier the flywheel the more energy is stored. When you accelerate the engine (increase RPM) the engine has to work to overcome the weight of the flywheel, hence a lighter flywheel = engine with quicker increase in RPM. Why do mass car manufacturers fit heavy flywheels? Well the points already touched on are all very valid, driveability for the less able members of the population is one. As compensation for mass market manufacturing tolerances. All engine components for mass produced cars are not made exactly to fit, there is an acceptable variation. e.g. your no. 1 piston could weigh 100grams and your no. 2 110 grams, if there was a 10% tolerance both positive and negative then this would be acceptable; in fact anything from 90 grams to 110 grams would be allowed. This is obivously not optimal for an engine, you want all of your pistons to weigh the same - this is however, a long and potentially expensive process, hence it is not done on mass market cars. The R32 as already mentioned uses a dual mass flywheel, hence its extra weight. The VR6 is easily stalled due to a number of reasons, the big one being the design of the engine. The close proximity of the two banks does save space but also has higher friction loses than a 4 cylinder, V6, V8, straight 6 etc. As such it requires more energy at idle to overcome its inherant energy loss through friction. So to realise more power and driveability from an engine, get all the rotating components dynamically balanced together, crankshaft, intermediate shaft, camshafts, pistons, conrods and flywheel with all the relevant ones fitted with pulleys (flywheel is spun as are all the others the normally rotate in the engine as Henny said) get your pistons and conrods weight matched, within 1 gram of each other is a good basis, 1 gram difference across all 4 is even better and you will see increases in both power and driveability, how much depends on how well your engine was built in the first place. Dec a bit late but the 16v from the corrado has the same flywheel as the G60, they also share the same crankshaft, so any g60 lightened flywheel will do!

g60bv 0 Posted April 22, 2007 but for every one. you must use new flywheel bolts. and torque them. i failed to do this on my engine and now its in bits. in less than 1000 miles it worked lose and shook by bottom end to distruction. you have been warned!!!

Rob Heath 0 Posted April 22, 2007 Is the golf and corrado G60 flywheel the same?? Quote Share this post Link to post Share on other sites
Yandards 0 Posted April 22, 2007 Yes to the Golf G60 and Corrado G60, its the gearbox that results in the change, the G60 golf uses the cable change box as found on all the C's. Quote Share this post Link to post Share on other sites
