Speed actually makes less power on the dyno.... less torque then the standard and slightly more HP..... but for pure power increase over the v-spec the Speed doesnt offer much....


But !!!!!! a big but here..

The Speed has a weighted crank... People may tell you it helps with engine balance, but thats pure rubbish really and not the true intended purpose of a heavy crank.....

In the last couple of years the big name companies like RB and Nova have gone to extremely heavy cranks in their motors... They have decided the heavier cranks make the motors more manageable on the bottom end... Making the engines come onto power smoother which also can make a huge difference in traction and maintaining traction..... As the heavy cranks act like adding a heavy flywheel to a car, they heavier the flywheel the more resistance to rapid RPM fluctuations and spikes........Adam Drake runs a very heavy custom steel flywheel on his Buggies to keep the bottom end of the Drake Picco's in check, without the heavy flywheel the tires would spin like crazy when motor hits pipe..... But with the steel flywheel the motors acceleration is much smoother and linear ( albeit slower)..... So these days with the prevalence of very slippery tracks, and very light fine tread race tires engine manufacturers have decided to add heavy weighted cranks to tame down the power delivery of their engines..... The heavier cranks do take alot whallop out of the trigger feel of the engine, but it makes the motors more manageable on the loose tracks........ You will find that on high traction situations some of these weighted crank engines can feel like real duds in the low end

So OS Speed is really just a V-Spec with a weighted crank to make the power more manageable.... As the V-Specs are know to be rather hard hitting motors, so adding the weighted cranks makes them more useable in a buggy.... The Speed will definitely lose some of that typical V-Spec explosiveness though by having theweighted crank....
