Lightweight Flywheel

[93_Clubman]

I would take the advice of a professional OEM engineer- if a major OEM employs someone to design/ implement engine programs that says something. Its pretty clear people will do whatever they want without actually taking account of facts. Most of the time people ask for advice but only wait for someone to agree. Its often a waste of time bothering to reply.

How quaint to believe in infalibility. Vehicles from major manufacturers are effectively products of a committee, with all the compromise that entails. Next you'll be telling us you still believe in Santa, the Easter Bunny, & the Tooth Fairy.

Btw, some people only quote what they agree with, & ignore what doesn't support their Morlock forelock-tugging dogma.

Fair go, he is only expressing a ultra cautious conservative viewpoint. If you can get past the prolix vocabulary he usually has a valid point to make. i would much rather have a vigorous discussion in this forum otherwise it could degenerate into ricer wankerism.

Prolix. Good word.

Road cars we were talking about.

Sports cars we are talking about.

what he said. sounds like you really, really don't like being told different from what you have made your mind up on.

like i said if you have a problem with a lightweight flywheel in a sports car get a shopping trolley.

...or better still, something with an automatic so then any change in flywheel is irrelevant and not required. Sorted!

Surely you're not suggesting Mr M drives an auto (as I do most of the time)?

I have a 6.2kg flywheel in my daily dríven MX5 and consider it to be one of the best changes I've made to the car.
It made it feel like a sports car not just a commuter-mobile.
With a small amount of practice (no more than a few days) it is no harder to drive than a normal weight one.
The engine now is much more lively and spirited.

B6 or BP?

I have a BP.

morlock, thanks for the targeted response. It warms me to know I'm in your thoughts with such determination.

Incidently, the original post wants recommendations on a lightweight flywheel, not the two opinions buried in your expert testimony of a (surprise surprise) stock setup.

Hey mexie lovers

I did the 1.6 litre 3.6 kilo + exceedy heavy duty clutch and it fixed a little bit of the yucky 1.8 doughiness on my NA8, I felt it was a good move but ahhh the memories of 2 girls fitting that big ass heavy mumma gearbox back in with the car on the ground in the dark.

I have seen some pretty cheap flywheel/clutch combo's on e-bay in america heaps cheaper than my sydney supplier (i'd better not say who I got it from)

Even a lightweight flywheel is still a heavy piece of metal which is rotating at high speed beside your legs and taking the odd serious shock through the clutch. These sub $200 cheapies do worry me. When you see that price you can't help but feel there couldn't have been enough money spent on making it in terms of design, metallurgy, casting and machining to make the it safe enough. If buying lightweight I'd stick to known brands with a clear commitment to quality and safety. Price isn't everything.

Droo you need to read a bit more closely. The guy did ask for advice he said "Am I on the right track? Car is used mainly as a daily drive with occasional track use. It is a 98 NB 1.8L." Thats pretty straightforward to me- a clear statement. The option not to do it is there.
The comments that I posted about lightened flywheels was penned by a professional ie someone who was paid by a real motor manufacturer to introduce engine changes on a well known vehicle and engine. He studied for an engineering degree and was paid good money to work with other professionals. No you do not get these with on the back of a Kellogs corn flakes pack and you do not get it from reading a few mags or talking to untrained people. I have no engineering training but had a lot of exposure to auto engineers and have a great respect for their knowledge.
