HS2 Vs. HS4 Vs. Weber 40 DCOE
Which of the following will provide the biggest power increase?
Twin HS2 carbs
Twin HS4 carbs
Weber 40 DCOE carb
Thanks!

split weber 40 (or single one)
but the head must be ported/tuned to ensure the biggest power.
hs4 are 38mm wide, DCOE are 40, it is just a bit better, but the inlet manifold tend to feed more the 1st and 4th cylinder (or 2-3 idk)
so the solution is to use split webers, with straight inlet pipes
All-out track cars use dellortos, all out road cars use webers. Get David Vizards book “tuning the a series”
