Hi

I have a rx7 s5 13bt, how much RWHP is possible gain with a Super Lightweight Rotor Asssembly, in this case, the racingbeat Super Lightweight Rotor Asssembly, wich each rotor weights less 1LB? What the benefits?

regards

 

from what ive read nothing unless its a race motor

 

you wont gain any significant hp
but you can rev higher more safely and the engine will be way more responsive

 

yeah... pretty much like getting a lightweight flywheel

 

DUDE,you really have to RE-read the INFO.
they take One pound OFF,so the Rotor is now 8.7 pounds,not 9.7 pounds(stock).
when I read your post,I thought Holy Crap!..they are Making the Rotors Out of Tin Foil!

 

Sorry the confusion.
but if each rotor wheights 8.7pound, are 1pound less than stock. 2 pound less in the assembly, I think that the engine have any benefit, or not?

 

not on a stock motor

 

You might get better gas milage too.

:giggle:

 

Yes it will have a benefit, and if you can afford to put them in your car more power too you. However this mod is obviously very expensive and there are many other things you can do to your car that have the same or better benefits for a lot less money.

 

I know that the cost of this, I can bay a turbo kit a gett much more power. But I want know, if existe benefits, what benefit? I get 10RWHP or more? rev faster? more responsive?

 

You would be better off Just Inflating your tires to 50lbs and greasing up your wheel bearings and Wax the car.

 

The engine will rev higher and be more reliable at those speeds. An increase in throttle response is also a result. However you will make less low end torque due to less rotating mass.

This is really a race modification only for aggressive ports like full bridge or peripheral. This is mainly an NA mod, since turbo engines don't have to rev up to make power (just turn up the boost).
