Wierd aero stuff

[Rabidhamster]

any ideas for this?



heh... I'm trying to keep the nice old school muscle look, so it's been kinda "fun" trying to find little places to block, vent, redirect air without a bunch of holes in the panels and a big cowl

it's going on an air suspension, so that will be it's "play" height.. normal driving height will be a little taller and I'm going with an airbag type that stiffens the spring rate as it goes down.

I'm thinking of panning the bottom, using filler panels and plexi to close up the nose opening some, and tucking the bumper closer to the body with a little custom work to give it more of an airdamn effect

I also am making use of some of the upper slots for ram air, and blocking off the rest, then cutting a channel in the center part of my firewall and using about 60% of the heater inlet as hood evacuation, yes it is getting a bed cover, with probably a dove tail moulded in or a spoiler on it, finally I'm gonna notch the bottom of the rear bumper for a lil better air path under the truck

at the moment I can feel it fight @ 70mph ..hopefully I can stablize it out some!

oh sorry... here's it's current ride height

Yes, Big Red went 200 with stock bodywork.....channeled over a tube chassis so it is REALLY low. But with well over 800hp and the right gears you can push almost anything over a deuce. As ProStreet said, 220 would be muuuuuch harder. The influence of Parasitic Drag and Frontal Area increases exponentially, not linearly as speed increases. It takes over four times as much hp to go 200mph as it does 100mph.

Isn't Big Red alot like a NASCAR wrapped in a 1st-gen appearing shell? I don't know but it seems like it.

Yup thats basically what Big Red is, its got a NASCAR inspired Tubular frame throughout, no fenderwells in the front, need room to run 335s haha which is sick.

The biggest problem I see here is the huge rock in the engine compartment. It seems like a rock that big would be plenty enough to hold the front end down. I wonder if he used big block springs.....?

It's probably a grey plastic tarp.

Have another,

Gives new meaning to the term: "Mountain motor".

LOL!

Interesting, I was actually planning on doing a lot of the stuff mentioned in the thread. Good to know I'm not alone.

Someone mentioned that if you seal the underside of the car and make it flat, you need to create a way to vent the excess air going into the engine compartment. My Nova has factory fender louvers (non-functional of course) that I planned to make functional by cutting out the back of each louver (maybe have a set made in carbon fiber! mmm). I've also got a 4" cowl induction hood, and the raised portion is open at the back (it has a little screen for "protection" I guess). Would the fender louvers and the cowl induction be enough "venting" or would I need to do something else?

Air will most likely be coming in through your cowl induction hood, not going out. The base of the windshield is a high pressure area.

But wouldn't the back of a cowl be a low pressure area? I could be wrong.

Maybe to vent some more air, maybe you could fab some vents like the following link has, on either side of the cowl: http://forums.nicoclub.com/zerothread/168601

I was thinking of something like that, actually. But more along the lines of the "GTR" style hood for the E46 M3. I don't know the name of the hood, but that's how my friend describes it. There's a poster on the wall at school of an E46 M3 lifting an inside wheel on a turn, and it's got 2 sets of louvers on the passenger's and driver's side of the hood. It may be a bit more complicated to do something like that on my hood since it's basically a hollow fiberglass shell. I'd have to figure out a way to cut through both "layers" of the hood, seal the hole so air doesn't just fill the hood, and then secure the louvers.

Actually that doesn't sound too hard, I'm just a little scared to cut into my $650 hood, considering the fact that Harwood is supposedly on mad backorder on their hoods.

I also noticed that the fender louvers are ridiculously short (they only stick out of the fender around 1/4"), so if I really wanted those to have any kind of benefit, I'd most likely need to customize them myself.

EDIT: This is the hood I'm talking about. If I did decide to modify the hood, I'd probably do louvers similar to these:

So that car is from Europe, are there any more pics of it. It might provide some new and diffrent ideas.

You are wrong.

The whole point of a CI hood is to grab the high pressure air at the base of the windshield to force a bit extra into the engine. A little free ram-air effect.

I stand corrected!

I looked into it when I was first laying out the one lap car. They actually have a five or seven piece kit including side skirts, etc. that they have available (fairly inexpensively) but in the end decided that it was probably too much. IIRC the air dam is available on it's own as well as grafted to the 'glass clip.
