I spoke with an engineer named Joe at the R&D facility of Aerodyne today. Aerodyne has a manufacturing facility in Dallas TX, and is the premier manufacturer of Turbos (aerocharger) for all makes and models of cars and bikes.

They have both a DS and Raptor that the are desiging a Turbo for, the raptor is further along and is running very well off the stock carb. The DS will be designed to run off the stock carb as well and they anticipate it will put out 70-75 hp on pump gas and will be able to market the kits for around $3500. An intercooler will not be offered as they do not believe that the stop and go type ridding of the average ATVer is a consistent way to cool the intake air (you've got to have a large volume of air passing over it at a high rate of speed) A water/methanol injection system will most likely be available by a company called aquamist.

(very interesting reading in FAQ)
For ATV ing it is actually more effective and consistent. Although 70-75 hp is a very respectable number for this size displacement, max power is not their primary objective, Joe says that useability and reliability are more important.
If any one is interested Joe can be contacted at
1-888-665-9697, I don't think they want to be inundated by questions right now but a show of interest for the DS turbo should help push things along a little faster.

 

Hey, you mentioned something about a turbo for the raptor maybe I just over looked it but where did you find it again? Thanks

same contact phone number in the above post

 

Gearing the DS for a 1/4 mile drag with the turbo may be a problem. With 22" tires, 18/35 gearing, you max out around 110mph @8000RPM and will be shy of the 1/4 mile.

 

sounds like you'll need bigger tires, more rev's, and a helmet

 

or if you could get a coustom rear sproket.
