I am relatively new to this forum and i am purchasing a titan this weekend.
I want to give you a little of my background tho. I am new to trucks, I have owned a hemi ram for a year however.
My previous experience has been with honda B-series and K-series motors. Both N/A building and FI tuning. I have owned (and personally built) a 1.9 liter b-series honda motor to the tune of 210 whp. I am telling you this because I want to know that I am have experiences, and have had tons of cars on every dyno u can think of.
I want to say that when I first got into tuning it was with a 1999 civic SI. First thing I did was your standard breathing mods, AEM CAI, Headers, Cat eliminating 2.5" exhaust. (big for n/a honda)
As my experience grew, I had went thru several intakes, and seen dynos upon dynos of intakes.
IMO on MOST naturally aspirated motors the best intake for pure power (yielded on a dyno), is a short, fat (3 inch on honda) , smooth, linear piece of tube (like stainless, or aluminum). With a big Fat velocity stack on the end.
Often the easiest way to achieve a combo like this is get your cheapo ebay short ram intake, and get a high quality velocity stack. (that will accept a giant cone filter)
If you know anything about resonance tuning, you know that the velocity stack and the length of the pipe can permit a slight "tuning" of the powerband. (rpms @ which power is produced.)
One thing that tends to happen with cold air intakes is they do make good power, (similar to short ram, its a cfm thing really) but the can cut down on response, and extra bends affect flow, place the filter in dirtier or wet locations, etc.
What appears (to me) to be happening with titans is what myself, (and a vast majority of weekend warrior tuners) fell victim too initially. Threads and threads about which "designer" intake they used and its power. There is absolutely nothing wrong with using a designer intake (esp. if you go the dough to blow) but I am more of a bang for the buck, function over fashion intake kinda guy. (once I started building cammed up, high compression, ported motors, I stopped worrying so much about designer bolt-ons)
These motors however are different, They are very expensive, and hard to work on in comparison, and not to be toyed with by myself (unlike ez b-series) So It will be a strictly bolt-on affair with the Titan.
After all that, what I really want 2 know is has anyone used the cheapo intakes? Have dynos? Anyone have experience with velocity stacks?
Below I have a cheap-O intake that would suit perfectly to what I am describing, it even has the heat shield. All it would need is a velocity stack, and a K+N filter sized to match. (that filter it comes w. wouldnt fit anyways)
I am noticing now that this appears to be of a similar design to the nismo intakes? I will have to check how they perform. W.O any guessing I am assuming that all these intakes are performing similarly? AEM, Nismo, Volant, injen etc.
ALSO is there anyway to "tune" the fuel maps after installing these intakes? technically if the motor is benefiting from the extra CFM it should be leaning out the motor? I doubt that they are making them dangersously lean by any means but generally all these breathing mods, I/H/E etc only show their true benefit when you can tune the Air Fuel ratios. They often need fuel added in spots and fuel pulled in other spots. (Velocity stacks can further pronounce this affect, at various resonances)
