i have a few questions abt intakes...now that i have a programmer, will i see a 4-5hp gain out of a cai. i am considering a volant system because of the closed box design.it says expect 9hp so im guessing ill get 4-5. Also, will a CAI system reduce IAT's? or will it bring in more hot air???
at this point i want to know if a CAI system will still be beneficial since i have the gryphon installed, if i can get 5hp and cooler air i probably will invest in one, otherwise its a k&n filter. oh and does a cai system come w a new MAF or no? because dont u need a maf that can read more air flow to really get the most out of an intake?

Regarding the IAT, check out this test from Banks. You can read the test parameters here: Banks Power | 04-08 Ford - F-150 V6 & V8>>Banks Ram-Air® Intake System ![]()

I probably shouldn't say this because our business is technically based on marketing and advertising, but here goes...
What would you expect Banks to say about their products? I'll give you that if you ran the Super Scoop Ram Air, you'd expect to at least see a noticeable decrease in ACT and I do agree that many "Cold Air Intake" system just suck hot air from under the hood making them not only misleading, but also rather useless. However, here's the thing about "Ram Air" systems... They don't work. This is a post from the Corvette Forum the explains in detail why it doesn't work. It's really an interesting read and even without the Pitot-Static Tube calculations, it paints a pretty clear picture. Quote:

Bill,
Thanks for that great post. I couldn't have said it better if I knew all the details (or how). My point was not to promote Banks (I've always known Ram Air is basically a marketing term). My college thermofluid dynamics class taught me that. My point was to debunk the COLD air intake marketing hype. Hence, like you, I suggested the Gotts mod and pocket the $250-350 an intake will cost. Unfortunately Truckin', Two Guys Garage, Power Block, etc. keep promoting how much we need to let our trucks breathe better. And we have just the product for you... ![]()

That was a great article!
![]() I also did the math not too long ago (Bill probably remembers me asking him what g/s means, I knew that info would be handy ![]()

And, the resonant frequencies in the intake system were something I was worried about in the Gott's Mod type conversion too. (I was thinking more along the line of standing waves, but it's the same idea).
I have no "test data" to back up any performance gain claim whatsoever, but, as far as I can tell, I'm getting the same fuel economy figures at an average speed of 70-75 mph now as I used to get at 55-60 mph before the Gotts mod. Before I did that mod, my fuel economy at the higher speed was lower. Very interesting article, Bill. Thanks for posting it. - Jack

i guess this would apply to hoods also. although they take in more air than a hood w no induction they fail to create more pressure, not to mention delivering it into the throttle body/intake manifold at 100% efficiency.
now i want a turbo, lol. i was looking to reduce IAT's but it looks like that is nothing to worry about either, 95% of my driving is highway. i plan on recording my MAF flow in g/s at a given speed say 65 or 70mph. after i complete the gotts mod i will re-test and see just how much more air im getting then before. i wonder if anyone has done a gotts type mod to a turbo equipped engine. just to get the turbo to spool up faster. hmmm

All the gotts mod does is help reduce the amount of vacuum caused at higher RPMs. If you were to rev the truck with your hand on the air filter or near the opening you would definitely feel it get stuck to it until the RPMs went back down. It probably would help a turbo spool up a little faster though. But many of the turbo setups I've seen have a regular pipe leading up to a CAI type filter. Unless the intake has a restrictive snorkel like the stock trucks there probably wont be much of a difference.

i had no idea there was so much more to intakes than i knew before,i guess it reflects 'marketing'...... im glad i didnt buy one.
ill b doing the gotts and a k&n filter, this thread made me curious abt lightnings though, i wonder if they have the same stock opening at the fender well, for the supercharger on these 5.4s
