I can appreciate you are offering your advice based on your experience.
My point is that no one in the fuel injection/engineering business agrees with you. That fact really is more important than whether I agree with you, so we would do well to put the debate in that perspective. Believe me, I take no offense in you disagreeing with me.

It also is conceivable that you know more than the recognized experts in the EFI industry, it's just that I believe you have failed to prove it here.

At best, you have established that you have been able to make oversized injectors serviceable, though that is far from making them desireable.

Pasted below are various links for calculating proper injector size. Interestingling, the RC Injectors page happens to use 200 hp N/A as a base for it's example calculation, which is essentially what we are talking about in this thread. As you will note, the calculation produces an injector size nearly identical to what I came up with. No big accomplishment on my part. I just used the same formula Russ Collins and everyone (with the obvious exception of yourself) uses.

As for the issue of how our boy's injector size affects his power output, I agree that it may not be the issue. But seeing he listed 525cc injectors was a red flag. Because they are well oversized and because he could have been running them for a time before tuning, it is conceivalbe that he rained out his cylinders and ended up with excessive bore/ring wear, leading to power-robbing compression loss. I am sure you would agree that 525cc in his application would be a disaster without some way to tame them, i.e. through tuning the fuel tables.
