K&n dyno results
 

as title says, i dynoed my car with k&n typhoon intake.
i read on this fourm that they had a problem fitting the intake with the throttle body. maybe i read wrong, but i did not have any problems installing them. it was a good fit.

the dyno i went on was a what people in vancouver called "heartbreaker" (mustang dyno at racing greed)
stock car dynoed at: 216whp and 175ft-ibs
with greddy tic: 223whp and 178ft-ibs
greddy tic + k&n intake: 229whp and 186 ft-ibs

pretty happy with the intake. the torque gain was noticeable for sure.
when i installed the intake... i was suprised that my car came with a block heater. does everyone have block heater??? it was hidden below the stock intake box
bad picture....

cool. do you know which cone filter model your intake uses? there should be like a 4 digit number on the box(?).

Wow those are low numbers... That really is a heartbreaker dyno!

I didnt have that low of numbers and I dynoed on a Mustang Dyno at Sound Performance hmmmmm..


Well a dyno is only something to base mods off of congrants on the install



DAN

is it RU-4960XD????

cool, yes it is. thanks! :tup:

RU-4960 - K&N Universal Air Filters, Universal Rubber Filter

are you sure they didnt cross your resluts with a 350z?

Something is way off with the dyno. Way too low. A stock 350Z/G35 puts out about that much...

all canadian 370z comes with a block heater

nop, the stock 350z dyno was about 170-180whp on that dyno...
more suprising... rx8 with greddy turbo kit pushed only 186whp hahahaa

Doesn't matter what matters are the numbers before and after. Looks like you also got 6rwhp with the K&N Typhoon intakes. That is what I got too. But I had numbers around 280rwhp...

doesn't matter what the numbers are, what matters is the gains each mod gives, which seems like a good amount. Don't let the numbers fool ya!

I never saw anyone win or lose a race on a Dyno. Good gains!

Yup it's all about the gains. :)

But I'm thinking they did your runs in 3rd?

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).

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.

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. :)

:icon18:

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.

Nice:tup:

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

:driving:

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%
