What injectors are you planning on using on the VFR TBs ? I really need 300cc ones with the bosch connector ....worried the VFR ones are not up to it ?..
Any pointers

I am using the Honda injectors that came with the TBs. The Honda engine made about 110 hp @ a little over 10,000 rpm. My 2110 should make about the same HP but at about 5500 rpm. And since flow follows power (my theory), these injectors should be pretty close to what I need.

Estimated minimum injector size (lb/hr) = (estimated max horsepower * brake specific fuel consumption) / (number of injectors * maximum injector duty cycle)
(110 HP * 0.50 [normally aspirated]) / (4 * 80%) = 17.2 lb/hr
Don't know how that matches to the injectors you have

Go with LS-2 coils and don't look back. It really helps in bringing noise down in MS circuits, Usb connection will be rock solid too.

Did you manage to finish this project, Max? I am interested how you did the linkage for the throttle bodies and what air filters you used.

Not yet.
The project has been safely under cover in the barn for a while. Not forgotten though.

Max! Have you been able to get any more done? I bought a 412 with SDS injection, and looking to do VFR throttle bodies, so tripped over your thread. Hope you are doing well.
