my throttle pedal doesn't have enough throw in it, so the best way is to multiply the output. Currently im only opening the throttle about 2/3
I'm after something like this, but not at the price of £130!! I'd attach the pedal to an inner hole and throttle body to an outer one giving
more travel to the throttle body.
But wondered had people done similar, or how did they multiply their output from the throttle pedal.
found out this piece is called a bellcrank.
If you find out the right name of pieces google becomes your friend! Hope this helps others in the future!
Can you not move the pivot on the pedal by either extending the arm or re drilling the fulcrum or shorten the arm on the throttle body, if it has a
snail try and find a smaller one
Last resort for me is a bell crank, I had one and it jammed open 
it was not well engineered and does add complexity, 2 x cables etc.

I had the same problem with mine. 
I made a multiplying lever at the throttle end, with a longer arm to attach the cable to:
And I replaced the plastic throttle cam with one I made from ally, with a smaller diameter, hence less cable required to open it:
Might work for you if you bolted it to the existing metal arm?
If not, you can make a bell crank pretty easily from 5mm ally plate and a few rod-end bearings; no need to spend that sort of money. Skateboard wheel
bearing for the centre, those rod ends are only a few pounds each from the bay, you can buy ready-threaded rod to join them or just buy some ss bar
and drill and tap yourself. But I'd have thought you only need the centre bearing and just attach the cable ends to each arm.

I had to do the opposite ie: increase throttle movement, but it would only need the cables swapping over to have the desired effect.
This could be done anywhere on the cable.

Ideal solution would be your throttle muliplyer..i like it.
Unfortunately space wont allow!, so it does look like i need to make a good bell crank and yes your right ill attach the cable to each end rather then have extra parts that aren't needed. ill probably put a return spring in there as well.
