The physics of accelerating on a drag strip and on the road are the same I’m sure.Yep, for drag racing it may be worth keeping the stock weight but drag racing is extreme - far more extreme that just fast driving.

Those numbers for the Imp fan are surprisingly high.Jon out of interest look at this link (scroll down). It's an article by a very well respected engine tuner David Vizard.

I used 6-7k a lot on track and I reckon a Datsun fan is far more powerful than an Imp fan (I've had 2 Imps), their rads are tiny too.
That is actually a great topic in its own right. Shall we start a new thread and move the discussion over to keep the thread on track?
Mr. Tenno is that possible?

I bought the Fidanza as it came highly recommended by people who build high end engines, had great reviews and has a replaceable surface should it ever need changing. It is a bit lighter than the one above - not been put it on the car yet, so time will tell when I get my engine back in.

If you go stock Nissan clutch then Mr F is your man - in fact, like John Shaft, he is THE man, period!

Ps. Sorry for the long reply - but you did ask!!
My Centreforce 2 clutch was not grabby or heavy to use - it's not a 'puck' plate either. I have no memory of any problems driving 'on the road' including long trips abroad (Spa, Le Mans).
I upgraded to a 240mm when I modified my engine. I installed a standard (Mr F supplied) clutch and it would not take the extra torque - it slipped. Hence buying the Centreforce clutch which was fine.
A lightened (or light) flywheel will absorb less power when accelerating - what is going to be used to spin-up the extra weight of the heavy flywheel? If you tried to spin them with a handle you would notice the difference I'm sure.
Driving technique - the engine 'spins-up' and 'dies-down' faster so it's great for upward gear changes and 'blipping' on downward changes. However I have not experienced a light flywheel on a standard engine so much of the extra responsiveness could be down to the engine characteristics too.
225mm v 240mm - why did Nissan go to 240mm, it must have been to cope with the extra power of the bigger engine?
Weight - I weighed two flywheels (225 and 240) and they were the same (21lbs I think). I had my 240mm flywheel lightened by 4 lbs but the bigger clutch was 4lbs heavier so no overall reduction from my 225 'set-up'. However is was lighter than the standard 240mm 'set-up'.
Woody,
I have a centreforce clutch in my z and whilst the weight of the pedal is a little stiffer there is certainly no drag and it’s also pretty unburstable too, or so I’m told. Luke
I'd always look to Japan first, then work back from from there engineering standards tend to go backwards also.
225>240, 6.25% ish?
Even you can't be too young to recall the
the year 2000 remake of the 1971 original ....
Haha this is a fair point, I usually just get put off by the shipping/import costs and language barrier. Particularly when compared to my contacts stateside as well. I think the OS Giken option is looking like a winner from everything I've seen now
I think with the right setup the difference will be negligible from what I've read from some of the US threads, so much conflicting info as usual though. Doesn't sound like much when you put it like that though.
You're still underestimating me here, even being a big film buff and a fan of many older films I only entered this mortal world in 1994
I'll add it to the list, it looks like a good laugh!
