There is NO way to get air any colder than ambient for obvious reasons, so no matter what set up you have if you are getting outside air in... that's as good as it's going to get.

The only way I would know (and i'm no mechanic) would be to increase the amount of air going into the engine and of course we could do that with FI, but without it, I suppose maybe a filter that has a higher CFM, but then the question has to be asked... how much air can an NA engine actually take in? You can design the most elaborate system in the world, but that doesn't mean that all of the air is going to be able to be sucked in and used efficiently.

As far as bang for the buck, I agree the post maf tubes and better filters are going to be the best way to go. I don't know how much power the fang vents would add, but it would have to be at least a few hp I would imagine. Here the problem is yet again though, how can they be tested? You could put a fan in front of each fang and test it if you knew the mph of the air and how much it was cooling the engine, but then, how accurate would that be?

If the stock set up with fang vents would work... where would the power band be? Would the ram air be able to compete with the G3's at the top end with that air being forced and sucked in at the same time or would it fall off?

All questions that really cannot be answered in all reality. There are 2 ways to tell, a dyno and 1/4 trap speed... i'd be interested to see myself.

Not necessarily true. Yes, they do pull "cold air" from the bumper but they also suffer from heat soak due to those big long metal pipes. From recent threads, dynos for the differences of the Post MAF Tubes and Drop Ins vs. G3's when you do other modifications (Exhaust...), makes the difference only a few HP. So if a few HP is worth $300 more to you, then go and get the G3's...

So, as mentioned earlier, if your looking to get every last HP, then G3's but bang for buck, MAF Tubes and Drop
Ins...

EDIT - Methodical, just realized you were in the last thread lol...
