hahahahaa yes ;D

I love the what you are doing to the hood by the way.

[xtremzj]

thanks! It will be great, i cant wait for it to be done! I have a new sponsor this year also so i have to cover up part of the hood, im justy making the decal smaller.

[xtremzj]

w00t all done. It looks great, cant wait to put it on the car.

The hood paint looks good.

Really though, I suspect you are getting very little effect from the hood scoop. You could however, make it very effective with some minor modifications.

As has been mentioned, the massive high pressure area built under the hood (in the engine bay) by the air being forced in from the high pressure area at the front of the car, through the rad ducting, will likely push air out through your hood scoop in the current configuration. This is due to the fact above hood area is actually in low pressure area as air flow is being bent (like the top of a wing) and racing as it tries to travel across the hood. There is a corresponding high pressure area directly in front of the windshield where the air get jammed up against it, but my guess is your scoop is too far forward to be in this zone.

The old Scooby rally cars made the early scoop work by venting the hood in front. The current ones work by directing the high pressure air out below the engine through ducting work (peek inside a WRC car, but not your local toy rally cars, as this so often gets overlooked!!!)

So you could do some quasi wind tunnel testing with some string on the hood and driving… record results of what is happening. Or be sure that you are actually getting some effect by sectioning off the air intake/hood scoop with a plate that seals (doesn’t have to be perfect) that area off when you close the hood.

So really current WRC scoobies have gone back to the IC (intercooler) in the front, and are pulling fresh air in for the intake through the hood scoop. Notice the sealing around the filter (at the back of the engine bay), this ensures the high pressure area under the hood is separated from the scoop ducting allowing the cool air to enter the intake chamber.

and here no hood scoop so both IC and intake are at the front in the high pressure region.

Man that's sure is purty

Alright I tried to imbed those but can't seem to make it work... sorry.

[SeattleJusty]

As always Matt, you explain it so well.

[xtremzj]

yeah so far the current set up works well but will make adjustments to it. You might not belive me, up from the stock air box there was def a "seat of the pants increase"
Yeah they dont run top mount IC they run a v mont system now ( the reason for the large duct in the front to let the heat out or vent to other places to let the heat out)

The plaid is sweet!

[xtremzj]

thanks! havent put it on yet, still thinking of maybe a fade on the fenders. not sure yet.

[Raw Justyce!]

I like the idea of the fade on the fenders. One thing I did on a RC truck body back in the day (checkers not plaid) was to have the squares peeling away, and it transitioned very well into the rest of my paint.

If you're having trouble thinking of how to fade it out, just keep it in mind.

[xtremzj]

its all on. looks good, need to put my sponsor/ regulation decals on and done!

[ncjusty]

That is pretty awsome! Wish I had a spare Justy to do the same.
Good luck at the races!

I think it's cute, you have a Mac Tools tach, but a big Snap-On sticker...
GREAT car! Keep it rubber side down and between the ditches...
