    Intercooler and Injector Questions?

    I have a RR wheel on the way and plan on doing a intercooler later this summer. I was reading that you can run the RR wheel and stock intercooler with stock injectors. But when you get the external intercooler you need 42 lbs injectors. Why is that? Does it make that much more power that the stock injectors just can't keep up?

    When you remove the stock intercooler from the manifold with it's restrictive 44mm inlet you flow more air since the throttle body is 52 mm.

    No lie here, depending on mods,,,a five mile an hour gain. I`m now running stock intercooler with an S3. I lost my ace. But the dependability or durabilty I should say is worth it to me and my waves.

    LOTS and LOTS of power. It's the single biggest power adder you will make to your ski...... until you bolt up a Rude Charger

    So how fast should my ski go with a rive grate, RR wheel, external intercooler, and 42lb injectors, and a rear air intake?

    There are alot more variables to consider, but with a 15/20 and RE`s you should be right at or near 72.
