I was just wondering if anyone had any experience with the RSM Throttle Body, offered at PFYC. Are they full of crap advertising 10+ HP gains or is that something realistic?

Also, does anyone know the stock throttle body diameter?

 

It is a worthy investment and the gains are real....

 

not sure about that particular TB but when i ported my own TB the gains were very noticable. most quote a 10 hp gain from UD pulleys and the gain i got from my port job was much more then the pulley... i barely can tell the diff with the pulley, but i love the new TB i say go for it

 

if you buy that throttle body let us know how it goes for ya
