Steel Billet Flywheel

Hi
Can anyone advise the best place to get a Steel Billet Flywheel for and SD1?? Best I can see is V8Tuner at about £240 (plus postage but including VAT).

Thanks

www.djev8.co.uk does them but dont expect much cheaper as thats what they cost am afraid. Real steel will probably do them as well.

Ive got a DJE steel flywheel, nice piece of kit,

V8 Tuner do an aluminium flywheel thats only 11lbs, I don't know the pros and cons of a non-steel flywheel but it sounds tempting.

I think the cons are basically rougher idle? Also bad idea going to light for a heavy vehicle, I think 11lbs is good for a kit car but maybe not a good idea for a range rover for example. At the end of the day the purpose of the flywheel is to store energy and the ligher it is the the less energy it stores.

The pros are the engine does not have to overcome the mass and thus the the throttle response is improved, probably good if you are doing 1/4 mile sprinting.

I am sure others more knowledgable will be along shortly.

I could live with some ammount of rougher idle, it would be going in an MX-5 so weight is not quite in the kit car area but hopefully less than 1100kg.

[adamnreeves]

Should be okay I would think. 11lbs I think is the minimum, I have heard of someone going to 8lbs and apparently just kept stalling!

I have gone for a DJE 18lbs steel one and was toying with getting the v8tuner ali one but I managed to get a good deal via from DJE Ebay at the time.

18lb's sounds like it might be a better compromise, have you driven the car with it yet ?

[adamnreeves]

Nope, not quite there yet.

The ally flywheel from v8 tuner would probably be ok since it only accepts a larger than stock cover plate anyway that will likely weigh more than the stocker. The net result will still be a whole lot lighter than the stock assembley but not undrivable I think.

I have a lightweigth aluminium flywheel in my MGB. That weighs less than 950kg think. Not driven it yet tho

I'd be intrested to hear your thoughts once you have driven it.

Hi

Just to come back to my flywheel dilema, I would just like an opinion as to if its actually worth it to get a steel billet version for my fairly standard RV8 3.5? I have a hurricane cam, webber 500 on an edelbrock manifold but other than that its fairly standard. Would I see any benefit or would I be better off spending money somewhere else and buying a new standard flywheel?

Thanks

Hi Martin

In my opininon, you won't see much benefit from the flywheel.
You wold be better of spending the money getting a 3.9 or bigger RV8 block.

As for the aluminium flywheel discussion before, I agree with Hairbear, it is no problem in a lighter car with a 10 inch clutch on top of it. My Rush has an aluminium flywheel and never given my any problems.

Yea, you won't get more power out of it but it'll spin up faster, if it's able to.

Can induce a whole load of problematic driving issues but you usually have to go REALLY light to get that bad!
