Lightened flywheel and clutch
Got a question and I think some of you might be able to help or give your info on.
I recently blew my engine and am going for a rebuild from Hurley engineering in the UK (Im in the Netherlands). 3mm seals etc. (Dont want to know about the seals, rebuilder and stuff). The car is getting a streetport.
I have just pulled the engine, and want to know if its an idea to go for a lightened flywheel. The idea is to set the car up for street and occasional drag use. Want to have loads of power for a good 10/ low 11 sec car.
Wat I want to know is would it be a good idea to go for a lightened flywheel?
Also do some of you have an idea on what sort of clutch to use? Your help is appreciated.
The car is a 1993 JDM FD. Want to go for a single turbo setup, something like a T78 or T88. Goal is to go for 500 RWHP. something like 600 BHP like I believe Vosko has?

If you are setting up for drag racing, you don't really want a lightened flywheel. Here's a quote about them and their advantages and disadvantages:
Yes, less load on the engine therefore less drag during the rev. Disadvantage is poor acceleration out of the hole for a launch, ie Drag racing. You need the inertia of the heavy flywheel because we lack torque, and since you don't produce much boost from a standing start, maybe 4 or 5 psi, the inertia from the flywheel spinning at high rpm helps to keep the engine from bogging out of the hole. The benefit on a road course is the flywheel is light and since you are slowing and accelerating rapidly the engine can recover the power faster if it doesn't have to work as hard to spin the flywheel to get the power to the ground!
