I was going to try to find an alum. N/A hood when I get my FMIC. I mainly wanted to do it for the sleeper effect, but if it actally HELPS air flow into the radiator and oil cooler, then that gives me another reason to do it =)

 

You mean this one?



Note that low pressure does not necessarily indicate a reverse flow. Low pressure is simply lower pressure. For example, you may have noticed that when your local weatherman states that your region is experiencing a "low", it doesn't mean that all the air is suddenly going to flow into outer space.

I have personally tested the TII scoop up to 70mph, and I can assure you that air flows into the scoop just fine.

 

Power assist under boost? no, that's provided by a check valve.

seriously.

mash the throttle in 2nd and pump the brake pedal.. you'll have power un-assisted brakes.

not quite, but you'll have manual brakes.

 

what makes me think this also is>> i was driving down the road with my tII hood... forgot to bolt scoop in and i hit say 60. it's the way the scoop flew off is what changed my mind... i can't say your wrong though and i don't want to, OR fight about it... agree to disagree....

i think the best thing to do is to allow for more air travel, what ever you do.... prop the back of the hood> add reverse vent> cut holes> what ever floats your boat.... its you car thats going to overheat, not mine, so do somthing

by the way>>>>>>HAPPY 4TH OF JULY<<<<<<<

 

Anything thats not bolted down will at 60 mph will fly off.

Anyone know of any charts like that of one with a hood-scoop?

 

 

FYI, in wind tunnel tests it has been shown that most of the air flows right OVER the t2 hood scoop and not into it. Poor design.

 

thats is exactly why I have no problem using it on my verts - shitty functional design however, cool looks

 

That's exactly what happens with any hood scoop. Air will always follow the path of leaste resistance, which is over the scoop, not through it. The only way to improve this is to make the scoop taller. The taller you make it the better it'll work and the stupider it'll look. The current WRX STi is a good example of this...

 

No ****....... thats is also a strenghtening factor in why this design should work.

 

Its not really a poor design. You have to remember that there is an intercooler sitting at the back of the tunnel in the hood. That intercooler acts as a restrictor on the airflow. Once the amount of air entering the hood reaches a certain point, no more air is going to ba able to flow into the scoop and through the intercooler and more and more air will be forced to go around it as the volume of air flowing over the hood increases. But we all know that SOME air is getting in there if only for the dead grasshoppers and moths we scrape off the intercooler every now and then!

thats is also a strenghtening factor in why this design should work on the car as well. The top edge of the cowl will sit about 3/4 of an inch higher than the back of the insert, thus getting it into the laminar flow over the hood.

I got my website up and running again, I'll be posting some pics of the design process and of the vac tests with the smoke generator.

If it works on the car (i have yet to figure out how to hook the smoke generator up under the hood of a running car!!!!), I've hooked up with guy here in york who makes dunebuggy bodies who says he could reproduce it for about 150 in 'glass and about 190 in Carbon Fiber. We'll see.

 

Its made by Re-Amimya and rx7.com can get it for ya... for $435!!!!! After rocky told me that, thats when i decided to make my own!

 

After thinking about the Vaccume under boost comment... yeah, i'll take the bullet on that one, after dealing with carb'd v-8's for 15 years, its kinda hard to get it out of yer head that vaccume isn't always present in an engine!!!
