what spring do you recommend for the stinger clutch? My son is gonna be running red plate/peewee thanks for info in advanced
Is that not the "chatter" engagement like on the other noram charts? Red plate stuff we had the red springs on our regular noram. It showed a similar chart and was around 2200 but that was just where it starts to engage total lock up was around 3000.For purple plate we run Orange, and our starts are as good or better than a bully clutch most times!
That's a hard/easy question to answer!what spring do you recommend for the stinger clutch? My son is gonna be running red plate/peewee thanks for info in advanced
So glad to have you back!That's a hard/easy question to answer!
First, let's get some definitions defined so we're talking about the same thing.
Idle = when the kart is just sitting there idling.
Stall = what the RPM is when you get on it and the kart starts moving.
Hook up/lockup = when the clutch stops slipping i.e. when the engine is turning the same RPM, divided by the gear ratio, as the axle.
Your stall RPM should be set to the peak torque of the engine. If you haven't had your engine on a dyno, it's easy to test for home.
Put a bathroom scale (analog) between a strong wall and the front of your kart. Warm the engine up and floor it. The right spring is one that will hold the engine at the highest torque RPM.
Torque X RPM / 5252.1 = horsepower. The highest torque at the axle gives you the highest horsepower "at" the axle.
