How much faster is the rx8 with this flywheel compared to stock? 0-60 times would be nice. Also, it weighs 14.7 pounds. Does anyone know how much the stock weighs?

 

it will change your 0-60 times, but you won't be able to notice it.

 

Stock flywheel is 21.5lbs


My advise is, if you want a noticable gain in power get a turbo kit. Last year, I bought lightwheel rims, lighter tires, light weight pulleys, intake, racing beat ram air duct. Voltage stabilzer thinking that it would make my RX-8 faster. It did. Maybe by .2 seconds

The improvement was there, but with all the money spent on those items I should of bought the Turbo kit.

 

I am thinking of getting the pettit racing supercharger when it comes out but usually flywheels are extremly good upgrades. On the mazda mx6 LS the stock is around 25 pounds and a 13 pound flywheel makes a 0-60 difference of about 1 second. Considering the replacement flywheel was a mx3 stock that costs $50 it was probably the best mod for the car.

 

racing beat web site said stock weight 16.8 lbs, so not much different.
you better off getting the racing beat, it weight 12 lbs.

so have you decided on getting the manual then?

 

One said 21.5 lbs, RB said 16.8 lbs.

Whos right ?

*confused*

 

The stock flywheel has a built in counter weight which weighs about ~4.5lbs if I recall.

So if your considering an aftermarket flywheel most of them list the weight of flywheel WITHOUT the counter weight. So most of the time you need to add ~4.5lbs to make a comparison vs. stock.

hope that helps.

 

the MS flywheel has a lot of material removed from the outer portions which make its rotational inertia the same as RB's... and its rotational inertia that really matters

 

Exactly - it's not the weight so much as where the weight is placed.

 

what about the act one? I heard that these are the best bang for your buck..

 

The aluminum flywheel by pettit racing claims its only 8.5lbs.
