This is my current model of a quad throttle adapter:






This has the following advantages:

- Near ideal port match from throttles to adapter and the same to the base it bolts to.

- Light weight: the adapter will be under 900 grams

- a vacuum port off each cylinder for MAP and a larger size for the brake booster.

- Holds the throttles the right way up

- Uses unmodified linkages between the ends of the throttles and to the top throttle cable mechanism.

- Throttles positively located to adapter via dowels to stop changes in tune from movement.

- Good port transitions: no harsh edges or angle changes.

- Will come with barbs, plugs and fasteners to make it a full kit.



Price should be quite low even with all the extras, aimed at $300 to 350. I am likely to have a lower price for those who pay 2 weeks in advance before these get machined so I can better plan on how many to get made.

I am getting a prototype 3D-printed this weekend and I should be able to test fit it for final checks this coming week. If that works out and I didn't miss anything then I shall finalise the price and work out the pre-orders.


Updates will be posted on here as they come
