    what does it take to turn a 14/20 without going too deep?

    I just got my IR lvl1 and my ski is a PIG. It came with a dynafly 14/20, mod ride plate, PPK and 1200 2bar grate. I have some adjusting to do to the rideplate. But it is a pig down low. I really dont want to go deep into the motor at all. Especially since I only have 11 hours on it... Its an 05 GPR btw.

    What can I do other than swapping my stock impeller back on or ordering a smaller impeller?

    I was thinking efi unit, filters and outerwares, jetworks, d-plate, and free flow. Any other options? I dont want to go with reeds and dont want to do heads. But if I have to I will do the heads before timing key and vf3's... Any help would be great. I was a little pissed becasue it slowed down so much and was terrible out of the hole ( where I play mostly).

    and before anyone says it... I asked if that impeller is to big for a stock boat and I was told NO. But then again its the one everyone goes with. Is it becasue most people end up going with more mods?

    My '05 vf-3 reeds,EFI controller and D plate with a 14/20 runs 7000 rpm which I think is to low but the stock prop run 7310 rpms which I think is to high. I need to add the air filter that I have layin around plus something else.
    Gps 68 in 1 ft. chop with wind.

    My ski did the very same thing, was sluggish down low with the 14/20. Only turned 6860 on the stock engine and Jims ride plate, but it would do 70mph. I added d-plate, efi controller, R&d flame arrestor it was way better turned 7100+ and ran 72+mph

    Cool... My Cobra was DSG 2003 and had a 2.4 KB, Stage 3 cams, built solid axle and everything else under the sun! Made 660rwhp on the JDM dyno... here was my post about it on SVTPerformance...

    The new owner just e-mailed me a few minutes ago to tell me that he added some of the extra parts I sold the car with and took it in for a dyno tune and it laid down 675/600 on a Mustang Dyno... man I miss that car... but I am an oil and gas attorney and I have clients in my car all the time and it just wasn't practical and with my new house and my wifes car payment I couldn't afford to have both the Cobra and my Tahoe right now.
