You want the clutch to hold the engine at peak torque, if the blue Springs will do that, then those are the ones you want to use, if not, you may need some different color springs.
When the clutch is holding the engine at peak torque, that torque is transferred through the chain to the rear sprocket. With maximum torque at the rear sprocket, you have maximum horsepower at the rear sprocket. Until the engine and the axle are turning the same rpm, divided by the gear ratio, the horsepower is different at the axle than it is at the engine.
RPM X torque / 5252.1 = HP. So you can see that as long as the axle is turning less RPM than the engine, divided by the gear ratio, the horsepower is different. Once the clutch locks up, the horsepower at the engine is the same as the horsepower at the axle.
