I am selling used SR Motorsports light weight pulleys and Goodyear belts that are in good condition. These pulleys sell for 400 dollars plus on their internet site but I am selling them for 225 dollars shipped. I am also selling a used Helix throttle body spacer with all the hardware and gasket for 50 dollars shipped. The reason I am selling these parts if because I am going back to stock. I accept paypal or cash in person if you can pick it up. Thanks.

 

why did you buy the spacer?

 

How were thay on you car? Did you feel the difference?

 

Seconded

 

I felt a little difference but you won't truly know unless you put it on a dyno. Check out the site and maybe call them and see if they have info on the RX8

 

the TB spacer is the TB equivalent of the Vornado intake insert...

All the work, effort, and R&D that goes into creating an induction system that keeps things as smooth/laminar as possible, and then you add a spacer into it that intentionally disrupts flow...

if you need to disrupt airflow to obtain a more complete mix and burn, you should be instead looking at injection properties and keep intake as smooth as possible

 

Helix throttle body spacer is sold! Still have the SR Motorsports pulleys available!
