I have heard that lightened Flywheels are the biggest bang for the buck. What would be recommend on a n/a 88, lightened steel or aluminum? cuz i heard that too light can be bad... bad idle and have to slip clutch more at starts, and lowered gas mileage. I was recommend steel because i use my rx on the street. But i heard that aluminum flywheels are only bad for TII on the street cuz low end torque is hurt or something like that? What should i do?

 

I have heard that the steel ones are recomended for street use too. But I think that is because steel is more durable than aluminum and less prone to metal fatigue. I have seen in many magazines they have used an aluminum flywheels on thier project cars. I am planing on purchasing an aluminum flywheel in the near future. A quality aluminum flywheel will have a replaceable steel piece where the clutch engages to help keep wear and tear to a minimum. Putting a light weight flywheel will not effect horsepower or torque, it is like reducing the weight of your car (in some cases up to 300 lbs.). I have a fomula to calculate what kind of "weight loss" it would be. The thought has crossed my mind to post it here. The only thing you may have to change would be your "optimum shift point." Well I hope I have been of some help to you.

 

If your clutch is good...an AL flywheel won't be unstreetable. Shane racing sells a 9.5lbs AL flywheel that is combined w/ an ACT street/strip clutch...and it is very nice..good engaging and the flywheel does make your 40 to 100MPH runs a LOT faster...I'm using AL on my GTR conversion...its all in what your looking for.

 

A lightened flywheel will reduce the rotating mass of the engine assembly (rotors, e-shaft, flywheel). If you decide to purchase a lightened flywheel, you will need to purchase the automatic transmission counterweight to go with the year rotors you have. Some vendors will include this when you buy the flywheel, some will expect you to remember to buy it.



The flywheel will help the engine rev easier. Less mass = greater acceleration. It should also help with your downshifting.

 

ILUV dude, RX7.com says that it will allow more power to get to its wheels. Torque is turing power right>? so wouldn't that mean your hp stays same torque goes up? can someone with one tell me>?
