Street car vs. Race car makes a difference. Force inducted race car doesn't care too much about intake design as has already been stated in this thread. However, a street car is not on boost 99% of the time and therefore behaves the same as naturually aspirated, so manifold design will have an affect on driveability. If you only care about WOT HP on boost then slap on any ole thing you want and it will probably function.


I really can't agree on this theory
The car will drive around just fine with efi as it's tuned with the map/fuel. It might not be optimal but it works.
I would think converting a single 4 manifold over a tunnel ram proves my point. With the unequal runner length and usual poor fuel/air distribution characteristics and issues they still work.
An equal length runner intake should blow it out of the water but the don't seem to.
Show me a factory F.I. manifold with unequal runners
