    What's it take to make old RXP/T 255hp

    As a Honda owner, I'm not up to speed (go ahead I set myself up for that one) on what it takes to make a 215HP RXP or RXT into a 255HP machine. I'm confused as to why everyone is jumping on it.. if its the same engine with maybe a different ECU and intercooler. I can see the big deal with the new Hondas & Yamahas..Bigger Motors more HP, but I see the specs and just see a 1500 4-tec that makes 255 instead of 215.

    IC is external, not internal in the intake manifold...
    SC is different, better...
    Exhaust is redone...
    ECU is setup to match changes...

    All together its a better BREATHING package, thus more power...

    This motor is capable of 300hp+ with bolt on changes...

    Thx Danny,

    Ok so what's it take to make the 215 into a 255 . Would that be a Stg 3 setup? Or a Stage 2 & 1/2. Whats it take to make a 215 a 300hp? I see alot of speed #'s but I rarely see a HP # when it comes to certain stage setups. For instance, theorecticaly, my Honda stock makes 165, MB & IC "remember theoretically" make it 205. So I know those 2 parts give me 40HP.

    The actual numbers for stages varies because of several factors, such as temp, humidity, etc....A ski running a Stage 2 in Michigan in October can make more power than a Stage 2 running in Florida...

    The RXP/RXT-x are basically factory versions of a Stage 2 install......with warranty

    Thx Jerry,

    Now I know. Thx Danny too.. So with the new setup the extra 45 HP should be attainable with bolt ons instead of $6000
