I have looked at mounting injectors at the mouth of the stack, because
of the more efficient fuel vapourisation. Obviously it works well for any
kind of racing where the throttles are wide open most of the time.

However, my research indicated that there are some drawbacks when
using this system for a car driven on the road. It seems that having the
fuel on the "wrong" side of the throttle butterfly is not so good for idling
and low throttle opening. And probably cold starting will also be difficult.

I'd be most interested to hear from anyone who is using this system on
their road car... and not just as secondary injectors that only come into
action at WOT !!!

If you look at formula atlantic 4ag's you see they all run secondary injectors infront of the stacks.

Obviously cold start isnt an issue, or is drivability in an open wheeler.

ust check the overall length, and the offset on cylinders 1 and 4 vs 2 and 3
