Porting a miniram.... worth it?
Has anyone ported their miniram to help balance the flow between cylinders? or should I just covert a single plane for EFI.

Re: Porting a miniram.... worth it?
Have ported a number of them but no answer on what could have been balanced.Only reason to port is if the engine needs it. They do fairly well as cast. The cyls where there is typically a little turbulence in the plenum area shouldnt really be an issue. Wondering if a firing order swap on the cam would help, thinking its really splitting hairs for no sotp gain but who knows
What are you running?

Not sure its worth it.While it may help some the air is being forced through anyway with your turbo.

it would take some work but could be done, sure. Seen one worked over to over 400cfm but takes a lot of porting and creative epoxy work. (and a bunch of $$)
Never flowed the ones I did. THe last one was a 1206 mini I believe wouldnt be surprised if it went just over 300cfm but I cannot say for sure as it didnt see a bench, wanted it to stay ahead of the 1054 AFRs (on a 408).
Dr Js performance in Orange County ca flows these a lot and could better answer your question.

No reason to switch to a single plane. Either run richer than your targeted air fuel ratio under boost to avoid detonation, or go with an XFI which has individual cylinder tuning. Expensive, yes, but worth it if your concerned about one or more cylinders running leaner than the others under boost....
