Anyone ever thought about destroking a DS motor. If you took like -3mm off the crank It would rev like crazy. This makes the motor 628cc, But revving to 12000 would not be a problem. Great for drag racing.....

 

Hmmmmm. Interesting.

Great question Antwain.

yes you lose a little torque but pick up HP and top speed. Probaly have to run different gearing.

 

Would your valves be able to work that quickly?

 

nhra drag racing has a class that uses crate motors,no increase in cub's allowed so they started to destroke these motors and twist the hell out 'em. it works! huge hp @ high rpm's ton's of money spent to keep them together. maybe when having to run a cc restrictive event this would work? (bigger is still better)[img]i/expressions/face-icon-small-happy.gif[/img]

 

Thank ya. uhh, Thankya very much! [img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]


Okay, is it possible to destroke a motor, then bore it to compensate the CC loss???

Hurycne,
Have you been talking with DSMike?
This would take a longer Rod(better) or a different piston pin location,then add a 108mm piston what would that be??

so is that a riddle???Jeffinrivercity????44hp, you better watch out for them predators. lol

 

I was thinking 'outside of the box' Maybe that is his secret. 830cc Jeff check your pm

 

Well you would have to use a very strong valve spring.
