As a matter of fact, a NACA duct (superior to our Porsche side vents) is only efficient as a ram at above 200mph.

2 weeks ago i performed a test using a fully radiused intake pipe on single cylinder induction tubes, and gained 12whp on a 320whp engine. Infusing such technology in our induction may prove benefitial, but the factory ram tube, incorporated with the "deflection cup" is a restriction, and hence, the power gains seen in the upper RPM range.

Thanks for the suggestion...great minds think alike!
Wow! Thant's amazing. Thanks for all the info. Sounds like you know what your doing for sure. Please keep us posted with any more dyno test you do with other mods.

Ram air vent ducts???

So what is your opinion of these "Ram" air vent ducts? I've seen 2 designs and was thinking of buying them before I de-snorkle my car. Any thoughts as to if these would realy work/help any more?

This is much appreciated Bisimoto! I hope you can get us a few mod dynos in the future as well.

When people risk their lives, shouldn't it be for something very important?
Well, it better be.
But what is so important about driving faster than anyone else?
Lots of people go through life doing things badly. Racing's important to men who do it well.
When you're racing, it's life. Anything that happens before or after is just waiting.

I am going to do this on the week end and remove both the restrictor plate and snorkel.


I'll report back w/ some test results.
