What NOT to do..............

[PKRWUD]

It sounds better than any other explanation I've received, but I'm still not convinced. The fuel added to the mixture has to be the key ingredient to the reasoning though, because the throttle placement on mechanical fuel injection works best as close to the heads as possible. On our Sprint, there are 8 throttle plates, and they are located within 2 inches of the heads, but we add 10 inch (some are longer) velocity stacks to increase the velocity. Since we have a throttle plate and velocity tube for each cylinder, we don't require a plenum.

So then I guess an EFI engine would benefit from velocity stacks, but hood clearance makes that difficult. Still, someone would have figured out something.

I'm still puzzled.

Take care,
