Any pics of these in a polo bay?

Can you really generate a ram air effect travelling around on "normal" roads ?

I was under the impression you needed to be doing a very fast speed - ram air works for jet engines - it is the same with most aero kits ... they look good but you aren't going to get any noticeable benefit driving at 110km/h on a freeway.

Hoping someone who's played with this stuff has some definitive answers and not more speculation as I'm skeptical about any benefit trying to "ram" air into the inlet ... you may get a benefit from colder air (not drawn from engine bay) but I just doubt you have the speed to generate an air mass great enough to create a ram effect.

To get definative answers, we would have to do it and measure the before and after. If the standard intake system from the front of the engine to the MAF is not restrictive (lets assume with the Seat 160) then whats the point? Well, with a better designed inlet, we may be able to force air into the system, reducing the work on the turbo.

Will it work? Depends on how well designed and engineered the solution is (or some luck!)

If you have not read the Intake restrictions thread, it has some ACTUAL DATA!!! Thanks to Awestonvp for his contributions.

For more research that has been done, check out Autospeed.com, or try this link - http://autospeed.com/cms/search/inde...rds=ram+intake

From some of the DIY's I've read, it is quite possible and cheap for tests to be conducted on our vehicles. It'd be a matter of getting the testing gear and a few cars together. I don't have the time to read it at the moment to give a quick summary.

EDIT - this is what I was thinking, http://autospeed.com/cms/A_1023/article.html
