I've seen some pics of the plastic 3L IM and I noticed that the injector sits in the middle of the port. I wonder how it would affect it if any, since it would be aimed at one port.



1. VERY Significantly!!! I could give you actual flow areas if you wanted.

2. True, but that makes zero difference in power production.
Also with some ingenious porting work you can easily get a bit of fuel to the secondary valve to keep it clean. That's all you really need anyway; something to keep that dirty pig clean!


Then keeping the dual runner manifolds will allow you to open up the heads a bit more (comparatively) for top end power and still retain great low range power thanks to just using the long runners.
