Tested by who? Believe half of what you read and 20% of what you hear.

32% of half of 73 of 100 people say numbers are ALWAYS correct.................
Half the time.

doesn't a turbo increase air temperature by compressing it? where does a turbo get it's power from? (exhaust gas, which is extremely hot!) once a turbocharged engine is warmed up, you can bet the body of the turbocharger is real hot! very few turbocharged engines have intercoolers.

for someone claiming to be an expert, you fail in simple mathematics. you have earned the MBE endorsement of "DORK". have a nice day!

A. Yes, compressing any gas heats it (law of physics, not my opinion). Turbos heat intake air two ways: exhaust driven, and compressing air. The giant increase in volume overcomes this. With intercooler it is even better. Superheated air is less dense than cooler air...without turbo, heating it has 'anti-turbo' effect of supplying less air due to its expanded state.

B. The 'cold air' intake system has been tested in a very solid and scientific way by ErnieF @ this blog:

Read his testing results and you can't even THINK about installing this system. He lists all the reasons and test results. Irrefutable.

i guess i'll do a DT exhaust first (after SG2) then wait...

you should look up "HHO" on youtube and see the idiots posting goofy videos with little hydrogen separator tanks that claim to double gas milage! running a V8 jeep at 2000 rpms (engine sucks down 12,000 liters of air a minute and claim their "bubbler" adds 1 liter of "HHO" per minute... they shut down the comment sections on some these videos after i debated these idiots)

i wonder what the volume of air (restriction) difference is between the stock and this unit. i saw the performance tests you posted. accelleration dropped, but so did engine load. so the engine is making more power.

it would be interesting to know if the fuel economy increased. they could have monitored this in their testing if they had a scan gauge installed. i have yet to see anyone posting milage changes with exhaust/intake mods.

i'm not really into performance mods anymore, i'm into "hypermiling". if i can get an extra 10% in milage with a little "kick" in performance, that's cool.

(my last car was a geo metro with a custom cat/exhaust, K&N air filter and 15x7 aluminum mags 195/50-15 tires) it handled like a go cart and in the winter was better than a snowmobile.

am i the only one who noticed that the person who posted the "tests" is affiliated with a company selling competing products

ummm, allegedly, the maker of the intake posted the results. an MB wonk posted them. i'm wondering what the hell is going on here.

the design looks legit, trying to figure out which way it would go when installed. gary states air flowing 3000 liters per minute gets heated 30F in what, a foot or foot and a half. we should harness this design, if it can heat 3000 liters a minute 30F!!! this is the most efficient heat exchanger on the planet!

I made no such claim. If you read ErnieF's report, he does NOT sell a competing product. He gave it up when he realized that the IAT increased by more than 30 degrees. It is not rocket science as to why. If you pull fresh air from outside the engine compartment it is cooler than the air inside the engine compartment, where this junk intake is located. Engine compartment air was more than 30 degrees hotter than ambient air intake (Duh!)

He also said that to get the junk filter into a fresh cool air flow you have to go to the bottom of the engine, where you are in danger of picking up water.

Where do you get the figure 3,000 litre per minute? A giant V-8 pulls about 600 cubic feet/min @ full throttle. hmmmm a 3 cylinder, 1 litre should go about 1/3 of that...200 cfm would be what in litres?

Gary,

It would be a good idea to compare apples to apples. Just because Ernie decided to mock my intake and create some sort of data it doesn't mean it's true. First of all, he has not tried my intake, he did some sort of "similar" setup. Unfortunately, his data is not valid enough to compare with my intake because, it is clearly not the same.

I think your goal is to just chop my Intake as low as you can WITHOUT even trying it. That's okay, you are not obligated to purchase my intake. Let's save it for people who really want the power and the response.

As stated before, you will be missing out.

Your 0-60 will increase,
Your 1/4 mile time will improve with faster speeds.
You will increase your power by 8 HP.
AND a much quicker response from start!!

People who have purchased my intake did not expect such a big increase but when they did they were impressed and would never even think of returning it. How can you explain 100% satisfaction?

Think about this, one of my customers said that they did buy the Breathless Exhaust. He liked it but it was too loud for him. When he installed my intake it improved the sound and now he absolutely loves it. Just a thought.

I think this discussion is over. Anyone interested can visit my website: www.smartcar-performance.com If you are not interested that's okay.

Let's keep this discussion at a mature level. I don't think calling someone's product "junk" is going to be appreciated by anyone. I don't talk bad about anybody's products and I don't plan on starting now. I know Breathless has been around for awhile. I just don't agree with his test results on his version of the intake. Simple enough.

3000 liters per minute with the smart 999cc engine in top gear at 60mph. 3000 liters is only 106 cubic feet. a one liter engine sucks down one liter of fresh air per revolution, a smart is geared to go 20mph at 1000rpms in top gear. it's simple grade school math.

i still say anything that can heat 3000 liters of air 30F per minute is damned efficient. this design looks like it getting air from a place in front of the engine. heat from the engine is naturally drawn out the back via vents on top of the bumper.
