    Ultra 250X Whipple Charger Kit.

    I have been working on a replacement charger for the 250. I sent a busted up Ogura charger to Whipple some time ago. The results was that a replacement was sent back that bolts directly onto the OEM mounting points. Testing at first wasn't all that great but with some injectors and a ECU swap things got alot better. I used an old RIVA SC unit ECU as it was a good match to the boost mapping of the Whipple.

    Testing so far has shown numbers in the 75mph range with the stock hull. Still using pump gas it seems that we may be able to get more by changing the pistons for higher compression thus demanding race fuel of 109 or greater.

    Still this is all just coming to light as we have a few bugs to work out before it becomes a full kit. Still as it stands the kit is in the $2700.00 range.
    Its the prop that we are trying to figure out now. Seems to spin off the bottom as we now have alot more torque do to the Whipple not lagging the motor.
    We are also trying smaller IC as the stock one is much bigger then needed with the new cooler style charger. As I said before this is still in the prototype stages and things may change in the total package. Keep your ears open as this is going to be the kit that pushes the Ultra over the 75mph range.


































































    I'm truly sorry but this has been an April fools joke. Tasteless might I add but I had a good laugh.
