944S dual k&n filter?

[JD159]

Quoted from the forum i found this at

"Over the last 2 years i have fabricated a system that has dramatically increased torque, horsepower, and throttle response it consisted of the nose panel from gt-racing.com and some 3 inch tubing and obviously k&n filters That and a cat less 3 inch exhaust to a Borla muffler put me in a 0-60 in 5.9 seconds And stock Performance was quoted as 0 - 100 km/h (62 mph) in 7.8 seconds."

Anyone think it may be remotely effective :S?

[Mankato944]

no idea but it looks sweet.

[JD159]

I'm extremely tempted to try this out myself...any risk towards the engine?

[porsche4life]

Shouldnt be any risk.....

[Mankato944]

I dont think it could improve airflow enough to make the car like 2 seconds faster. There may be 2 filters, but they still converg into a single one like the stock setup.

Just look at the intakes on hugely powerful normally aspirated cars like Vipers or TVRs; They don't need as much intake capacity as this particular 190bhp Porsche is equipped with, so it is just a waste of time and effort.
Porsche would have fitted such a cheap solution if it was really going to enable more power to be produced.

I dont know how much truth there is to that

no car ever comes out of factory allready maxed out, there is always - however little it may be - room for improvement

I'm not saying that they don't know what they are doing, I am saying that there are these "cheap" things worth trying out - and seeing if there IS an improvement

I mean if everything is so perfect from the factory, then what's the need with tuning suspension, or improving interior, or wheels, or brakes?

not hating, just saying

LOL...umm, NO.

[rmconner80]

The only way to know if there is an improvement is to take the car stock to a dyno. Call this data point (A)

Then take it to the same dyno, same setup (stock) on another day. This is data point (B). You may note a difference in performance between data point (A) and data point (B) - this establishes some measure of random variability and lack of precision in the test.

Then install ______ upgrade, and take it to the dyno for data point (C). Observe the difference between data point (C) and the other two stock data points. If the difference between (C) and the larger of (A) and (B) is greater than the difference between (A) and (B), you can be reasonably confident that you accomplished something.

I don't think I've ever seen this type of experimental control done unfortunately for any upgrade on the 944. So it's all estimates and hearsay, which is cool, but not really helpful or reliable.

I think the stock air box hogs in enough air, but who knows?

Also, I promise you that a 944S with a fresh engine in good tune will do 0-60 a lot quicker than 7.8 seconds anyway. The problem here is that most 944 cars are not fresh nor tuned these days.

Man, this one time, I just took off everything in front of the MAF and removed the exhaust manifold completely. Without all of those intake and exhaust obstructions, my car ran 0-60 in 2 seconds!

It's all about volumetric efficiency. On an N/A engine there is only a short time that the intake valve is open and the piston is moving on the intake stroke. Air has to fill as much of the cylinder area as it can before the intake valve closes. The lowering piston creates a low pressure zone allowing air to flow in. No more air can flow in than is available at normal air pressure (14.69 psia at sea level). You could put a dozen K&N's on there and wouldn't grab another ML (or CF) of air. Turbo Charging boots the amount of air pressure available to flow into the cylinder area during the intake stroke.

Yeah, I'd rather not have to take the front nose off just to check/replace a filter...

Interesting concept. Good purpose. Poor delivery.

now if you took out the headlight buckets, added 2 more cone filters THEN you would have something

I say leave the headlight bucks in, but route the filter to the headlight hole. Then, if you want MORE POWER, you just flip the headlight switch and the filters now have direct frontal mega ram-air.

I'm going to patent it. People would buy it, that's the sad part.

This is what happens when you have one too many cups of coffee!

The headlight buckets thing would work really well above 250 mph, but problems could arise when approaching the speed of sound. Course at sea level that still gives you about a 500mph window, but get up in them Himalaya mountains and you'll be limited to under 650mph and thats just no fun slaloming round all the national flags on the peaks in a car with such good handling.
