    Question External intercooler Vs Green Wheel

    If you don't want to buy a RRFR or bigger injectors but want more performance i have been informed that you can fit the Green Wheel with the standard Intercooler or the External intercooler with the standard Supercharger impeller but if you fit both you will have to uprate the fueling in some way which i don't want to do. Which would be the best performance mod to do?

    External Intercooler
    OR
    Green Wheel
    as i can't have both?

    No you cant have both without going to a RRFPR or 42 lbs injectors....
    Most people would say,including myself to go with the IC and stay with the stock SC wheel..BUT until this weekend i got to see your two cinairios run against each other...

    A buddy of mine has a 07 RXP with a External IC,4 inch air intake,Thru hull exhaust,stock SC and injecters and a 15/19 3 blade.

    My wife has a 06 RXP with a Internal IC,4 inch air intake,Thru hull exhaust,stock injectors and the greenwheel SC wheel running a 14/19 4 blade..

    Well as the day went she took him every time...SO i have my doubts about the IC over the SC wheel..If i hadnt seen it for myself i wouldnt have believed it either.....

    Honestly I know you said you can't have both but if it were me I'd do the green wheel, external ic, and the rrfpr. I personally would just save for all 3 and call it a day but if you really really can't wait then I would probably just do the green wheel. When you've got more cash get the rrfpr and external ic at the same time.

    NO....But if you havent changed out the OEM ceramic clutches you might want to seriuosly consider doing that also....

    and how easy is it to install?

    I have personally never done one but from what i hear its fairly easy

    What SNOMAN said. To me this is a no brainer. The super charger is going to be much easier to do, and you absolutely need to change to the metal clutch washers. If I were in your situation, I would pull the sc, drop it in the mail to Jerry for the washers and green wheel. You'll know the slip moment is set right, you won't be second guessing your work, and you won't need to purchase any of the sc tools. Good to go

    I lean towards the SC wheel in your case. It keeps the engine bay cleaner and has less parts to rub, bounce, or fail. However, the intercooler will probably have a slight speed advantage (0 - .5 mph) and increase fuel mileage.
