N/a bigger injector questions.

My friend thinks he need 55cc and 650cc injectors on his N/a. I keep telling him not to waist his cash .but he won't listen. He thinks that bigger injectors will get him more power. Please prove me right so he listens.

Well your friend isn't too bright. More fuel does not equal more power. Its only if you have large amounts of air to maintain the same A/F ratio, thats when it makes more power. Otherwise, he'd be running too rich.

Larger injectors are usually for turbo guys running higher boost than stock where the stock injectors can't put out enough fuel and causes the mixture to run lean and possibly detonate.

unless he has forced induction, a HUGE bridge-port, or a peripheral porting job he will never need bigger injectors. If he gets those it may not even run, and if it does it will have no power. He needs an S-AFC to manage them correctly. If he wants to spend money on fuel he should buy an S-AFC and LEAN OUT the mixture with the stock injectors.
