DG Ram air hood dyno?

[o.g.sk8er]

What do you all think about this?

What I'm wondering is what's that gain from just the Short Ram intake alone. I'm almost certain that you can get the same gain from a simple intake mod.

i love the way it looks. i wonder if anyone with a turbo kit has this. it looks like it would vent right where most peoples intakes are.

Actually, I believe the DG Ram Air hood comes with a setup that allows you to vent air right into the engine (as opposed to 'feeding' an intake).

$1000 for 5 horsepower?

Yikes.....

Can you paint it to match your body? Carbon fiber just doesn't cut it for me.

I say paint everything, but the Carbon Fiber Vent. That would look sick.

The problem with any good outside air induction kit is that you can't find out what the power gains are going to be like going down the road. If it has a ram effect as the car speeds up, then it should be worth more than 5 HP. You'll just never be able to duplicate the gain on a dyno unless you can measure the amount of pressure at different speeds and then duplicate the pressure on that area of the hood while on the dyno. Expensive.

It's a good idea though. Why do you think racecars have their air intakes in the airstream? It makes power. I had a Dodge Challenger T/A years ago that had the factory ram air, and it made about 10 HP more at 70MPH according to factory testing. But it was a VERY efficient design. The lower opening on the scoop was placed one inch above the hood to keep it out of the boundary layer of air and the inlet was in a good location.

i agree. that vent looks sweet

basically it does the same thing as a turbo right? just on a much smaller scale. What if you hooked up a boost gauge and measured the pressure at different speeds...Then duplicated it on a dyno with some sort of air compressor?

That's a pretty good idea, don't know if it can be done...but good idea. I think the main thing people are paying for is the look of it, wich is I have to say, very sweet. And it's a nice bonus that you might get some power out of it. On an autocross course it would basicly be an efficent CAI, but on the 1/4 mi and freeway driveing, I'm sure it would provide a nice little power boost. Just dont' take it in the snow/hail/sandstorm/anything else.

Thats a good thought. But I'm sure the heat of the engine would melt the snow before it clogged the intake...but what about rain and water. Does that pose a problem?

I'm sure they made provisions. I've seen all the old muscle cars with there ram air hoods and they all have little drainage holes. The problem is the bigger the drainage hole you have (for safety) the less "ram air" it is because some of that air is escapeing through that hole and not being jammed into the filter.
I always thought it would be cool to have some kind of remote controll thing where when you push a button or flip a switch in the cab the intake opens up. Like pop up headlights, but pop up hood scoops. Kinda like the vents on that new lambo I can't spell. Meurchilleo or something...

I thought during some dyno testing, they have a fan in front of the car to feed air into the engine?

you can not simulate the air current with a fan going the same speed constantly. you'd have to have the fan blow harder as the mph increase. to do this accurately, as Travelerstated, is $$$

MX3 - Thats what I thought they did to better simulate real gains.
