also the good about these KN filters is they dont sound like a toilet flushing when you're on the gas. :D

Your toilet shouldn't growl kenchan, better get that checked out. :)

Ok, wait...lets not get carried away...number DO matter. Does you car feel like its running well? Reason i say this is because the DYNO helped me diagnose my old car (350z) was not running well. I went to a dyno jet and pulled 200rwhp stock on a 2003. There were other 2003's stock putting down 225-235. Thats a big difference! I dont if the dyno you went to reads low or whatever, but when i took my car to nissan (with dynos!) they did a compression test and found out i had very bad compression in 3 cyclinders on a 6 month old vehicle( back in 2003).

my car runs pretty good. comparing to other 370z i drove, my car got more torque cuz of intake and exhaust.. maybe its just my head haha.
the low numbers are normal for the dyno i went on. lots of high horsepower cars go there to dyno and found out the dyno reads a lot lower.

Stop using that dyno and tell others to not go there.

Honestly, unless you dyno'd atop of a mountain, you should never have numbers that low.
It effects your gain results as well, as it will "read" them as low. aka if it's 6hp it's probably 9-10

I am pretty impressed with this Short Ram Intake! I do miss the intake growl of the SRI. I went back to a stock box + smooth tube design because my Takeda SRI turned out to be a crap. Good to see a nice SRI option that increases power.

I have a question about dyno numbers, doesn't location effect how much power the car is able to produce. for example above or below sea level, with the different concentration of air, so let's say if you are 2,000FT above sea level you will get a lower power reading compared to 2,000FT below sea level?

the location does matter. the place i go to is higher altitude than most dynos locally. i think "higher altitude" is the right term to say it. i got a better deal there and my previous cars have been done there too. they are a good shop and they are nicer than most shops around (on first impression) and their work and prices are good.
so i wouldnt tell people not to go there, but i wouldnt do any more dyno pulls since its now 90/3 pulls... they gave me 30/3 pulls.. thats why i did the dyno pulls

Good results. So it looks like the filters are where the gains are rather than the tubing. K&N drop in filters have been shown to give 5-6hp and 5-6 torque. These short tube intakes appear to give 6hp and 8 torque, roughly the same as the drop in filters. So it's a matter of preference of look rather than performance. Good to know. Thanks for the dyno graphs.

Jordo!

Heart breaker indeed -- that dyno is giving values about 25 - 30% lower than a dynojet.

The altitude may be killing actual power, tho' -- less O2 in the air. Be interesting to see what you make on a dynojet with SAE correction. Not sure what kinds of corrections Mustang dynos are programmed to apply.

A 6% gain from baseline with CBE and K&N sounds about right.

HFC's or TP's will probably net you another 3-5%
