If you already getting 15-18whp from 70mph fan from the scoop, imagine highway speed at 120+mph with scoop

Usually people who install the scoop notice a big different at speed 80+mph and the car keep pull harder and harder and speed climb

Keang24, does your car have OEM Intake Box or like AFE (with cone air filter)?

Tomorrow in the road to my workplace.. I will test the run in the highway with the version 1.2 (angled to 90 degrees) .... And will post here the results...

I have OEM box. The AFe like intake will always lost power on s85 engine, imo.

OK, guys. I decided not to run the dyno/tests. After I researched about scoops and it is very debatable (from other forums as well). Gains or not. I don't care. I will keep my homemade scoops as a look like our wheels, spoiler, etc...

I know it is a personal taste. like or not.

Also I made this scoop to exit some extended air out (to radiator).

Let's close this tread. (Anyone who want make a homemade scoops, don't hesitate to post here, )

Thanks!

Like or not... Gains or not.... I don't care! plus I am proud to make my scoop.

hey, Miguex

I like the look of the car & ur creativity!!!

I don't know Eloy or RPI scoop, but if it is still patent "pending" (or even if it is patented), I wish him good luck suing anyone for "inspired-by-RPI" homemade version.
It will take years and there's no guarantee of winning!!! especially international lawsuit? forget it!!!

Haven't you all seen fake chinese-made Ipod all over internet?
Haven't you seen fake Louis Vuitton bags???
Why do you think Apple and the French company can't stop them from producing & selling imitation fake crap?
(even fake 7 series on picture)

This is DIY forum, give this guy some credit for creativity!!
He has no intention of selling, & only throwing ideas here.....



p.s I am not a "NIRE"

sort of reminds me of the non-M e60 cars out there with the M5 badge

Thank you, Terry! Right! I made this scoop for my own use and never have the intention to sell. nothing else!.

Some guys don't understand what is DIY for.

Until you dyno that thing and get some true numbers, it's merely for looks. Don't get me wrong, I do admire your dedication in your effort

it's all marketing. dont get me wrong, i am sure they did lots R&D before finalizing the product but if I made a product with 5 minutes time and made it look very nice, would you spend big money on it? Absolutely not. Remember fluid dynamics and aerodynamics? both very similar concepts and we can picture with liquids a little easier. turbulent flow is not good. You want laminar flow. There's also transitional flow that's in between. In real world life, there's hardly any laminar flow. RPI designed so that there will be less pressure loss and try to pressure the air as much as possible through the tube. There's pressure loss due to friction at all times and with SO MANY 90 degree angles, it will create HUGE turbulent flows. Re=density*velocity*diameter/viscosity. Laminar flow: Re < 2000; Transitional flow: 2000 < Re < 4000; Turbulent flow: Re > 4000. The better the design for air gushing into the tube with more pressure (higher the pressure, the more force it has going through the turbulent flow around bends and friction), the more air it will go into the tube resulting in the air box. That's a main reason why it's angled at 90 degrees rather than 45 degrees. More pressure. This is why it wouldn't work at low speeds. it's useless. Now if there's a variable switch depending on the speed, the angle of the scoop changes, then we're talking but by then, why don't we just get a supercharger.
