what was the wait time?
They told me Varis has shorter times for carbon versions. Told me 3-4 months to produce + shipping. He said Varis is very good about keeping the purchaser up to date on where their product is in the production line.

Saw one at the SoCal CTR Gathering this past weekend. It certainly looks like it would dissipate heat more effectively. Not sure what to do when it rains though.

I ran open louvers on my drag corvette, left it in the rain a couple on times on accident and drove through the rain that caught me off guard. I believe leaving the hood vent open wont hurt anything at all.

I modded mine this week and should have it finished in the next couple days. I made a Red/black Carbon/Kevlar insert already, same material I made the bumper vents out of, as seen in my sig.

Exactly right! The engine can be sprayed with a hose so rain is not a factor.

I wonder if this causes lift due to entrapped air in the engine bay, (the air that doesn't follow the flow or the scoop channel in the rear of the hood leading to the fender vents.)

Got an update from him. Working on a couple different designs but it all starts with a perfectly measured base :headbang:
Looks similar to what I have done so far. Nice job! Are you going to market it? I may sell a Carbon fiber version.

If anyone wants cooler engine bay temps, you can just remove the aluminum pan underneath as an option.

Air still goes into the channel but allows some exit as well. I also took off the bottom aluminum pan, removed the fake valve cover plastic garbage heat blanket and peeled the cowl seal. I will make the same cuts that Varis has in the outer hinge area as well. None of it will matter until much higher speeds and I can close all of it anytime I foresee big speed.

Ok so it does indeed have the "louver effect" when air passes over it?

There is an issue with the ignition coil seals, where they will be rusty. I wouldn’t want water to drop down there’s for long.

Did you cut the tray? Why not just remove the uselepart all together since you’ve modified the “scoop”.

I don't think water from the vent will get back there, it has a small percent chance IMO. When you are stationary, the rain falls straight down infront of the engine right on the turbo. When moving slowly, same effect, when going over 45-50 the "louver effect" starts to happen, causing a vacuum to form at on top of the vent, sucking air out of the vent, which will mostly be hot air from the turbo and the radiator. So I don't see water creeping back to the top of the motor under normal conditions.
