You don't think that while the car is driving down the road that the air that's being sucked in by my GEN 3's is colder then the air being sucked in by a Short Ram.

i can tell anyone that is using this sri that if you remove the rubber strip from under neath the front of the hood.out side air will definitely get to your filters.

It could be. You absolutely may be right. But my point is (and I'm not trying to pick fights here) is that without actual data, it might not make any difference (or it might be worse) to have air intakes that snake down around the front of the car vs short ram intakes.

Other factors also need to be taken into consideration when choosing an intake such as piping length, diameter, material, etc... These things also affect HP which is what our ultimate goal is.

Ultimately what you are happy with is what matters, but please don't automatically assume that an intake will make more power just because it takes in air from an area of the car that seems to be cooler than another.

long tube intake dyno

http://www.the370z.com/intake-exhaus...pressions.html

~20whp gain


short ram dyno

http://www.the370z.com/intake-exhaus...ed-w-dyno.html

~14whp gain


33% difference of hp gained in short ram vs long tube

i'm sure there are many variables that play into this, but these were just some quick examples i found

now as the car warms up, both will lost hp, but the intake located under the hood WILL lose more power than the remotely located intake

Fair enough, but there are actual dyno numbers that have proven certain long tube intakes like the Gen 3's perform better over the short tubes. Temp readings, while useful data, isn't as important as the results in HP & Torque. I'm sure all the temp measurements were done to during the prototype stages of these intakes. If the results of those testings revealed hotter air with the long tubes, the power gains would have showed it and Nissan certainly would have chosen a different spot for the intake to get air from...which is why you don't see much of an improvement over the stock setup. The stock intake is pretty much a short ram that takes in air from a slightly "colder" source in front of the engine bay, above the front "mouth", not within the hotter engine bay.

Alot of variables involved, but colder air is more dense with oxygen...and more oxygen means more power.

So with all this hype as far as short ram goes......

Stillin Gen 2 Vs K&N what you all think?

I personally was thinking gen 3 but they are pricy. But then again everything on this car seems to be pricy.

Perfect. I will accept any arguments that are backed up with genuine dyno results. :tup:

Be glad you don't drive a Porsche.

For real’s!! But I want to and this body was the closest thing to it.

I'm extremely pleased with the way my car looks, stops, and handles. I wouldn't change a thing. :tup:

Power and sound on the other hand... I might be making some changes soon. ;)

I have a OBD2 Bluetooth with Dash Command iPhone app and discovered something interesting and useful! An intake temp reading. It shows live readings from the engine and I was seeing some interesting data. I have the K&N Typhoons and while driving I was getting ~90 deg but when stopped for a few minutes was getting to 145! So heat soak is there. But when moving it goes away.

This is exceptionally useful information.

Perhaps we can get someone with Stillens to hook up this setup and try it out? We can get some numbers to put a better label on the actual difference between the two. Very useful info for those that daily drive their cars and don't feel like removing their bumper every 10-20k miles to check their filters.

There are trade-offs on all sides, of course. I wonder if they have a similar setup for Android. I will be ALL OVER it if so.

TJLazer - what was the outside temperature at the time of your reading?

It was around 80 degrees. I will do some more testing, and also in the fall to see if the numbers get better when at a stand still.

I do know that when it is hot out, and in stop and go traffic I get a lot of bogging and slow throttle response in 1-2 gear. There is a whole thread about it and I am convinced it is the ECU going into a save engine mode. Happens when I hit 220+ degrees.

My neighbor has a 370Z I can see about doing some comparisons on his stock Z...

Post MAF Tubes & Filters :ughdance:

Besides, once other breather mods are added, those manufacturer claims go to the garbage...

At CIN motorsports they hot lapped my car on the dyno for 20 plus pulls, and tuned it for real track and driving experiences. According to there track team the short ram intakes provide more off cornering accellerartion compared to the long tube intakes that have somewhat of lag when trying to spin up. In all the Z's that they have tuned the only thing that they recommend is a good exhaust system. When I asked them about my intake system thet said "there all the same" maybe one or two horsepower if your looking for that on the top end...
