Blah blah blah, funny thing is the tundra comes with a oil/guaze ($90.00) stock. Relax it's only an experiment this is costing me zero as I volunteered my truck for it. Toyota makes there own(TRD)version of this same product so I don't get why you had to go into 5 fackin paragraphs of half-azz opinionated non-scientific bull sheee-iyte.............Why are you here again? is it because your einstien or your a chevy owner?
What? :td: Here's my five paragraphs, which you're probably gonna skip anyway, but maybe someone will read and take note:
McRat obviously knows what he's talking about, and doesn't need to use "half-azz" euphemisms to sneak worthless trash talk past the language filter in order to make his point.
How do I know what he's talking about? Easy...we (and most other forums) have been through this years ago...search around, you'll find it. You really think your truck is that different because it's your truck? Intake, cats and exhaust...particularly in imported vehicles are very close to optimum tune already. Toyota even went the extra mile on the 4.0L V6 to make sure everyone knew they spent time tuning the intake for efficiency from the factory. Every CAI and high-flow filter on the 4.7L showed LOSSES, even drop-in filters, at low rpm, with a negligable gain in open loop operation due to the overly rich mix being leaned by the additional airflow. Toyota isn't a bunch of hacks. If the stock filter is oiled gauze, maybe it's worth your time to compare it to other, non-OEM, oiled gauze before you claim they're all equal. McRat's comment regarding paper vs oiled gauze/foam is because current aftermarket oiled units are more porous than paper. Maybe the Toyota unit is different, but you're not able to say it's the same or different without a scientific comparison.
Free does not mean good. Airaid isn't a bunch of hacks either, but realize they're starting with a near-perfect system in the first place, and making products for a market that's usually more concerned with the appearance of performance than actual increases in torque. The majority of CAIs decrease torque at the bottom end...feel free to search the forums for why. You'll eventually find comparison studies on places like bobistheoilguy.com...you'll probably even find dyno charts on a variety of vehicles.
Great, you got it free. It might actually improve your torque. We'll see when you post the dyno graphs...not the peak numbers, the entire graph. If the graph doesn't start until the powerband on the 5.7, ask about performance at lower RPM. Also look at mid-band performance and WOT performance...if this engine is anything at all like Toyota's past engines, it will run rich in open loop, and you'll see a gain there. It will initially run lean in closed loop, probably lose torque at the bottom, slowly regain until open loop, and then slowly lose the gains over the entire range as the engine runs rich to self-protect from the changes it sees between the MAF and the O2 sensors due to the intake.
Think I'm nuts? Maybe this is all pseudoscience or maybe I really drive a Ford and I'm just ragging on your sweet deal? Nope...just trying to make sure everyone reading this thread understands the difference between a noisy engine and a powerful engine, and the difference between trolls and scientific reasoning. They can read my comments about trolls on that trade-in thread.
Enjoy your intake. In the end, if you are interested in a noisy engine, it will work out for you if you don't care about performance numbers. If you ARE interested in performance, let's all look over the dyno charts when they're available, if they actually release them to you. I bet they don't...and if they do, they're gonna be trimmed and stretched to highlight only the gains. If they show dyno numbers below 50% redline I'll be pleasantly surprised. Nobody is trashing your deal or your intake...just pointing out that there are many known caveats to CAI systems, particularly in modern vehicles, and that few people are willing or able to understand them beyond the noise and the bling...many CAI manufacturers have been more or less abusing that trend for years, rightly assuming that no guy is gonna admit he made a mistake spending two bills on something shiny for his wheels, and that everyone else is gonna floor the pedal and assume the first reading from the butt dyno is correct.
I don't suppose anyone makes a "throttle body spacer" for the 5.7 yet...
