Duel Throttle Ratio Change

[danielbrookes]

Morning,

Hope everyone’s having fun tinkering, I certainly am :).

I have a question about changing a throttle cables ratio.  I am not sure what to search for/solution to implement and wondered if anyone could help.

I have a duel throttle supercharger setup which is now working fine.  The problem I have is I am not able to get full throttle travel on the supercharger throttle.  This is because the throttle on the inlet is fully open.

Both cables are attached to the pedal so move at the same time.  I’ve read about leaving slack on the supercharger cable but that’s only when the throttle opens too quickly; I have the opposite problem.

Do I need to fit some kind of “ratio” device?

I am hoping something clever that sits inline with the cable is available.

Thanks,

Dan

I had the same problem on my Zero, I didn't like the throttle pedal ratio and I wasn't able to get quite full open throttle.

A heavy duty spring either end of the shorter cable?

Post some pics of the setup. especially the throttle pedal.

Can you connect the supercharger cable a bit higher than the other throttle cable giving more throw?

Sorry for the silence guys - had a bit of an accident in the garage, managed to get a small bit of metal in the eye from angle grinder.  Trip to A&E all sorted but lesson learned.  I'll be wearing my welding mask in future.....

Might have a look at this tomorrow and will post pics up then.
