People are repeatedly remarking about the difference between a stock intake and a CAI....and then from a CAI to a DCAI....
the DCAI is probably responsible for 8-10rwhp....= 2-3%.
but they also feel the grunt in going from stock to a CAI ......
.....and have even noticed the diff between a CAI and DCAI...
those lesser differences have gotta lie somewhere less than 2-3...say 1-5-2% improvement.
Well - thats what we are talking here - at least 5 rwhp.....
So I reckon you'd notice it - and there's always the placebo effect - so in that case you gotta feel it regardless.... hey
1. What you're referring to.. commonly known as a butt dyno is a joke, without going to a dyno/track, g-tech or dynolicious will be able to tell if a mod actually did anything 100 times better than the butt dyno.
2. A difference between a CAI and a stock intake is right around the margin of power difference that we would able to detect ourselves.
3. You will gain exactly 0 whp with a DCAI over a single CAI. For one intake to give more horsepower than the other, a few things need to occur: better placement of the air intake point to get cooler air, better filter element, the lesser intake creates vacuum at full throttle and thus limiting the air flow.
None of these are true with the dual over a single, you're paying $800 for just the look. If a 1000whp Supra can get away with a single pipe intake.. I think our 'monsters' can too.
Similar concept on so many cars with four bangers and V6s that have dual catbacks that splits from one outlet past the cat... all about the look, in reality single exhausts tend to flow beter and provide more gains as the exhaust gases have a straighter path to the muffler. With a single CAI the air would travel quicker from the intake point to the TB thus having less time to heat up in the piping and the air at the elbow would have a much smoother flow than a dual having two flows coming from two sides, sort of like merging traffic. If this was not the case, I'm sure NW would provide a dyno chart comparing the single vs the dual.. obviously they won't as they make way more margin in the dual so why discredit their own product.
All this talk is about the air that has not been compressed by the charger, the denser the air is at this point the denser the charged air will be once it passes through the compressor. After that it won't make a difference at all as demonstrated by the ice box project that lowered temps significantly and provided poop in gains.
Here is a real dual intake on a Viper with a dual intake manifold, drinking with a straw split into two at the end won't make you drink faster lol.
