Not heard of them personally - seen they do a high comp bottom end too.

The flywheel they do looks like a standard flywheel machined with holes etc. not sure how safe this is tbh. Might be worth asking them what material the flywheel is made from and if it's a standard flywheel machined?

For the price might be worth paying a bit more and going for an ATSpeed lightweight flywheel ? http://www.saxperience.com/forum/sho...d.php?t=287700

I dont like the idea of their flywheels. I have only heard one bad thing from this company that an engine they built didnt last 2k miles. However i do not know the ins and outs of it

Yeh QEP can machine a bit off your standard flywheel.

Personally, if I was building up a high reving NA motor, I'd only ever look to buy a lightweight flywheel that was designed to be lightweight as opposed to machining off material from a standard oem flywheel.

Just if it goes wrong it'll be pretty awful tbh. not worth it for saving £100 over going for an ATSpeed one IMO.

The high compression bottom end does look nice on the face of it, but IMO it does look a bit overpriced, could build it up yourself for under half of the price - just takes a bit of care, time and knowledge.

one word of caution
lightweight flywheels make idle worse --so for a road car not the best of ideas .
lightened flywheel does not give any more power -just makes engine rev up quicker ,and also looses revs quicker ,
the whole purpose of a flywheel is to smooth out the engine at lower rpms and somewhere for the clutch to fit.
If you car does not idle smooth now --it will only be worse with one fitted.
max safe weight you can take off std flywheel is around 1kg,
the thinner you make the flywheel the less mass there is to absorb heat from clutch .

a definate no.no for a turbo car --it will only make the spooling up more sudden .
and wheel spin worse.
If you car is mildly tuned there are better places to spend a few hundred quid.
If want std one made lighter I will do it no problem £35+vat

I will be honest -- no ,I would not balance it as there is no need as i would only take material off areas with no balance holes.
so i would not upset intial balance of flywheel .
you want it balanced add another £60
by now you will be horrified --i would ask to see the balancing equipment and print out from anyone else that you send your flywheel to .
it won,t be done
the crank is mass balanced on tu engines and the flywheel is balanced on its own ,so providing you take even amount of the balance will not be upset .
If you told me you were going to rev it to 10k + --then ok ,but then again I would also tell you to buy a steel unit and not use std unit.but for road going engines revving to high 7,s --no need.
I don,t even do it to my own engine--experinece of the engin over the last 10+ years has shown its not required

If you want tocheck what I am saying --put one on a wheel balancing machine --set to fine so it measures to + or - 1 gram and see what it shows -- bugger all
then you better do the same with your clutch as well. LOL
