I did the sweetest free mod today!!!!

[UKunt]

haha and its ur first DE-MOD. next time take 1 spark plug off will sound good as well and its free

hot air is bad

cold air is good

[Marek]

he i figured it different with my rc :P

[low_civic]

i would say now go out and spend some money you cheap bastard and put an AEM intake system and it will sound meaner and give a better result..

no way man ive gotta drop 5 bills on tires soon.... 2 tires

it is so nice to have connections, i put 4 of these Sumitomo's on the wife's car for $160 mounted and balanced
i got the hook-up from a local tire shop, i tinted the owner's windows on all his vehicles and his shop and he hooks me up

in this case temperature has nothing to do im almost 100% sure

No :banghead: . Colder air is denser allowing you to get more oxygen in at once. Colder air is always better. You are in no way close to 100% sure :loser1: .

Yes, the intake air temperature will be higher, but after a certain speed, the IAT stock form and the IAT of the modified stock will match.

Here some data collected from my car comparing stock intake with an open element intake

Temperature today was 55.4F and the two test were done without one hour of each other. The car used is a 2001 Mustang GT. The stock intake used had the silencer removed.

I did a IDLE log just to see what the intake temperatures are like. Engine coolant temperatures were the same.

STOCK

IAT MAX : 92F
IAT MIN : 86F
IAT AV : 89.42722266F

ECT MAX : 202F
ECT MIN : 190F
ECT AV : 195.1125098F

MAF MAX : 522GM/S
MAF MIN : 427GM/S
MAF AV : 468.1471282GM/S

K&N FIPK
IAT MAX : 112F
IAT MIN : 90F
IAT AV : 102.4705F

ECT MAX : 202F
ECT MIN : 190F
ECT AV : 195.8300551F

MAF MAX : 565GM/S
MAF MIN : 443GM/S
MAF AV : 489.9677419GM/S

As you can see, the IAT for the K&N is higher than the stock one for obvious reasons. The K&N is fully exposed to the engine compartement as opposed to the stock one which has a casing around the whole filter. So when the car is not moving, K&N will have a higher IAT.

Also, MAF reading for the K&N are a more than stock.

Here's a graph of both runs at IDLE for 120 seconds


************************************************** ****

The next run is a 1 mile higway run from one exit to another. I tried to keep the same speed and driving habits so the data can be relevant.
STOCK

IAT MAX : 110F
IAT MIN : 84F
IAT AV : 91.99381F

ECT MAX : 196F
ECT MIN : 190F
ECT AV : 191.8602F

MAF MAX : 19 910GM/S
MAF MIN : 538GM/S
MAF AV : 2376.385GM/S

K&N FIPK
IAT MAX : 104F
IAT MIN : 68F
IAT AV : 73.77699F

ECT MAX : 202F
ECT MIN : 188F
ECT AV : 191.5991F

MAF MAX : 20 707M/S
MAF MIN : 485GM/S
MAF AV : 2511.444GM/S

Right away you see a differene of 18F in average IATs. Since the K&N filter is more exposed, air flowing through the engine bay can be sucked in by the K&N filter. The stock filter being enclosed in a plastic shell, can only suck air from a small area, close to the fender. With K&N you can get IAT as low as 68F. So, once the car is moving, K&N IAT will dramatically drop and will have a cooler charge than stock even though it's not a cold air intake kit, just the fact it can be in contact with the air outside flowing through the engine bay can reduce IAT.

Here's a graph of both runs. You can see those two fine curves, those are the VSS of both runs, in MPH, so you can see the speed are very close to each other in both runs.

You can see that the STOCK IAT and K&N IAT will match at around 30-35mph and the K&N IAT will drop sharply after



************************************************** ********

Here's a 3rd gear pull on the highway atabout the same speeds. I've also calculated the RPM curve equation and VSS curve equation.

As you can see, the acceleration with K&N is slightly higher than the stock one. K&N is increasing at a rate of 30.602 RPM/Unit time as opposed to the stock which is increasing at 30.132 RPM/Unit Time.

VSS for K&N is increasing at a rate of 0.5296 MPH/Unit Time compared to the stock's rate at 0.4906 RPM/Unit Time.

The fine red and green curves are the IAT during the run.

^^wow someone has a bit too much time on their hands!
but nice work

with this thoery in mind wanna explain interCOOLERS and COLD air intakes and ICING down your intake between runs....

can you please tell us all here how you feel right now being so wrong about this topic?

Muhahhahhahahahha well he did believe himself 100% just got them the wrong way round. lynch mob is out for marek :thumb:

he had so much feel to what he was writing.......but it was all worng............
