It's not like we haven't noticed he hasn't been back in the thread in the last 8, or 9 pages.I guess he found another forum that still has a rep system.

I hate that I keep dogging him for this, but it's really lame. I don't mind at all that he bought the intake, I think it's great. I wish I had $1200 to drop on it, I'd do it in a heartbeat.

What sucks is that he trolled around Bill's cowl induction thread, knowing we were addressing a lot of technical questions. Then after he posted his bling bling, he didn't (or couldn't) answer anybody's questions. Freaking lame.

or provide us with dyno sheets to prove his claim that he spent $1200 for "something that really works". $1200 for the intake > $75 for a few dyno runs.

He's probably working overtime trying to pay off that 1200 dollar loan or pulled over somewhere trying to get the bird out of his airbox.

Can't blame him for that. All that for e-cool points, then Webby took away rep!

:rot fl:

I bet he's a god over at FG Coupe though

I'm over there and he hasn't made it there yet.

What questions havent been answered?

i STILL think a dyno sheet wouldnt show realistic gains. those fans they use dont push air that fast, regardless of the fact the air box has the hole thus taking a bit away from the "ram" air effect.

OH, and the intake can be had for 1067.xx shipped. well at least that was with shipping to WA state ( my location) lol

I wonder if you could put a leaf blower in front of the car and aim it in that general direction to get the effect. Have the person move closer as the speed climbs.

i wanna see this thing in action

I think that the point of airscoops is to ram air towards the intake at high speeds.. Because a dyno is taken at a stand still I don't think it will accurately show the real gains from this intake.

***NitrousG35*** · 03-24-2008, 01:00 PM

Guys, it is impossible to dyno a car with ram air, simply because air velocity is needed over the hood to create a high pressure zone at the base of the hood, or if the intake is at the front, enough velocity and pressure to be rammed into the motor. A fan will not work no matter how large it is as the air is turbulent and uncontrolled and relatively undirected. You also need pressure transducers at the front of the car and base of the windshield to measure the air pressure.

A moving plane wind tunnel would be best. Unfortunately, only F1 teams have access to them. In my thread on cowl induction, a Miata was modded with cowl induction. They noted it was impossible to dyno the car. A far better way was to do 0-60 and quarter mile times before and after. They noted that with cowl indution, 0-60 times dropped by .5 seconds, which is significant. The best test for ram air/cowl induction is to do a performance test.

Would people buy it for 954 shipped???

Why? Are you selling them for that price?

^ I believe that is what he was quoted shipped to his house from them.

Not to contradict you but the miata tests were hand timed with a stopwatch

So, what's the problem? All car tests used to be done by stopwatch before computerized testing. Read any magazine test from the 60's, and this was standard procedure. Even Formula 1 qualifying and lap times were done with stopwatches. A stopwatch can be quite accurate if done correctly.

Wow. That's a lot cheaper than what the OP paid. BTW, I believe Carlos of SCTuned was going to order 10 or so of the Gruppe M. Knowing Carlos, he will be able to drop the price for us if he decides to carry them. I approached him about becoming a vendor for Gruppe M.

I wish it was dyno-able. I'd be more confident in the numbers.

I'm not. Have you seen variations in dyno numbers? This has been discussed here on the forum many times. Corrected, uncorrected, Dynojet, Mustang, Dyno Dynamics etc. A dyno is a tool for adjusting a car and to see the effects of a change to a car. As I said previously, it is impossible to dyno a car with ram air. You need a moving plane wind tunnel with pressure transducers. The real test is not a dyno, but how the car performs on the track.
