    Cayman Turbo RXP

    Simple setup.....The gold of the build was to go as fast without spending too much. So I decided to go with turbo (GT2871) To go fast you need the right hardware!!!. All the part used to construct this project was used with all the factory OEM parts.(J pipe, water box, and a few sheets of metal)The engine is a fresh rebuild,all OEM components I first started the engine using a AEM FIC to control the fuel but took it off so i could just use the stock injector to break in the motor until am ready for big boost.
    Am using a 15 22r 4blade I NEED A PUMP!!!! trust me!! BoOst comes in early and hard!!

    you cant just go by plugs or by PSI and say your safe...get a a/f in it before you loose another engine... a big turbo like your running a 9 psi is like running a BIG charger at 15+ psi...

    A Lil advice for you, change your rubber houses to aluminum hoses, under to much pressure they will collapse. If you need any help let me know.

    I took it out the other day for a run,used a friend 42s with the stock ecu @ 9psi stock pump setup. With the new prop (15/22r) I can feel the differences at mid range but am still spinning the prop at like 5000 rpms I like that the power is coming in at a lower rpm, unlike my supercharge setup that I have to be revving the full 8000 rpm to be building max boost. May question " Is there any known pump setup that is taking the rider over 83-84mph at 8000-8100 rpm???

    I think I have the power to see the numbers. I know more tuning is needed !!!!

    You will need a higher limiter, there is only so much pitch you can fit in the stock pump, keeping it off the limiter with the stock ECU will be very difficult, you will need as much pitch as possible on the trailing edge of the prop you have but to be honest get a ecu that's going to let you rev to 8600+ then the speed will come easy, You can break the 80 mph mark on the stock ECU but everything has to be right, the fuelling will be tricky to get correct over the whole rev range as your going to need pretty large injectors to run any sort of boost safely.

    Good luck the build but do yourself a Favour and get some means of watching the air fuel ratio, things can and will go bang fast if your not carefull.
