So along with going from cast iron to steel I've shaved a further 2.76 pounds off my rotational mass along the crank line. Rob also confirmed the 4.5 Chimaera got the 28Lb millstone I had in my 4.0 litre.ДЄs already stated I have now gone for an all steel bespoke machined flywheel, this weighs exactly 8.5kg which is 18.74Lbs. V8 Developments machined & lightened version of the above = 21.5Lbs (what I have now - big improvement!!!) Std Rover SD1/4 Litre TVR = 28Lbs (what I started out with) I have just found my old post way back in 2011 where I started looking at all this and have seen the following figures were given to me at the time by Rob Robertson of V8 Developments. I've given you everything I know, so perhaps someone can fill in the gaps in my flywheel knowledge and share with everyone on this post? So my solution was to have a 19lbs steel one made by TTV Racing which by all my research and calculations should represent the ultimate sweet spot for my TVR and driving style.ДЄs for what the Griffiths got is anyone's guess but I'd speculate that all variants (except perhaps the 4.0 litre Griffs) had something lighter than the stupidly heavy 32lb SD1 one TVR fitted to the 4.0 litre Chimaera? We all know the 4.3 TVR RV8 was a sweet revving unit so it's possible the bespoke TVR cast flywheel I'm calling the 5.0 litre flywheel actually started out in the 4.3? I have a 4.0 litre producing 260 ft/lbs of torque so felt the 15lbs was going to be a bit too light given the way I like the car to drive and trying to find a TVR 5.0 litre cast flywheel for sale is obviously not that easy.

The steel one that's readily available for our cars comes from TTV Racing near Ipswich who are a renowned flywheel specialist, they offer a 15lb steel flywheel for the Rover V8 and hold them on the shelf.ДЄfter the success of reducing my flywheel from 32lbs to 25lbs I actually felt I could go even lighter, so because I'm already on the limit of machining my SD1 one further I either needed to find a 5.0 litre TVR flywheel or buy the very light 15lbs steel one from TTV Racing. TVR clearly new this which is why they commissioned the bespoke casting for the 5.0 litre cars, so if you want to go lighter than 25lbs you either have to find a 5.0 litre flywheel or better still buy a new chromo steel one. If you have one of these SD1 millstones in your TVR I highly recommend you get it lightened but as already explained you can't really take it's weight below 25lbs or you'll be running the risk of it shattering

Slicing a full 7lbs out of my flywheel made a big difference, the kind of difference you could really feel and TBH there were no drivability issues with it whatsoever, the exercise of lighting my existing SD1 flywheel proved to be an absolute no-brainer. TBH I'm not sure if the 4.5 Chimaera got the 5.0 litre flywheel too or just a machined down version of the 32lb Rover SD1/ 4.0 Chimaera one?ДЄll I know for sure is when I took the flywheel out of my 4.0 Chimaera it was the ridiculously heavy 32lb Rover SD1 saloon car jobbie so I had V8 Developments machine it down to 25lbs which is what they consider the safe limit. The bespoke TVR 5.0 litre casting looks different to the Rover SD1 type, it has a kind of spoked arrangement as shown here. A 32lb flywheel may be ideal in a 1500kg 3.5 litre saloon car designed to waft four passengers through town as smoothly as possible, but in a 1060kg 4.0 litre sports car 32lbs is way heavier than needed and far from idealДЇrom the onset of the 4.0 litre capacity the bore size of all RV8 engines remained the same, so as we all know the 5.0 litre engine is merely a stroked 4.0 litre, which invariably meaning two things:Дў: It produces a significant slug more torqueД«oth these characteristics pretty much forced TVR to do something about flywheel weight so a bespoke flywheel was cast and fitted to all the 5.0 litre cars, this 5.0 litre flywheel is reported to weigh 22lbs but others have weighed theirs and found it to be just 19lbs. The 4.0 litre cars unbelievably carry a standard Rover SD1 flywheel which weighs in at a stupidly heavy 32lbs. all our cars have cast iron flywheels and none were fitted with steel. Thanks, SteveNot sure if this will help as I can only really speak for the Chimaera side of things but one thing is for sure. What is the weight of a Griffith factory flywheel, 400, 430 & 500?
