I have a 09 Lancer GTS, I am interested in the RRM pulley. Anybody have information on the actual gains. Thanks for the info.

 

the only thing that you really gain is increased acceleration and torq, as far as hps all you gain is the hps that the heavier pully was restricting. thats all.

 

There will not be HP gains with this mod. This is mainly to increase throttle response, especially when running things like the A/C in your car. I had it and can say it was worth every penny!!

 

yea like these guys have said. Quicker response on the initial get-go.

Don't expect anything to change in the top-end. It's really only noticeable in the low-end.

It was my first mod. i've kept it ever since

 

it's a fantastic mod. the stock pulley is heavy so uses more hp to turn it. The rrm one weighs about a lb and it frees up the extra power that is used to turn the stock pulley to go to the wheels. It's a noticeable gain in the initial go. Go for it and installation is very easy as long as you have an impact wrench.

 

sorry this might sound off-topic but would changing to light weight rims give throttle response too? light wheels easier to spin

 

ya ull get better take off from a stop but once ur moving and such its not a big difference.. the stock GTS rims are 18" 24lbs the lightest 18" rims are like 17-18lbs but if u drop down to 17" or even 16"(smallest rim for the GTS) ur speedometer would be off unless u got taller tires which would prolly make it equal the same weight as having the 18"s..
