After reading your article it just proves Junpower right. No testing is necessary since any and all openings will always yield heat expulsion, including hood lifts, right?

With proper ducting to direct air to and through the radiator you'll maximize the radiator's cooling efficiency. If you seal off the bottom then MORE air will escape through the vents in the hood.

Of course all openings will radiate heat, but you want to maximize the pressure differential across the core. Without wool tufts or a magnahelic (sp) gauge you can't possibly know. Sure you could compare your IAT's before and after but that will be dependent on a number of factors well beyond our control.

There are 2 other articles in the series Part 2 and Part 3. I would really like to see someone provide a case for a hood with evidence.

Heres some picts of aftermarket Hoods for ,,, and or customized on the fcs for you :

And some more: And I got alot more but I dont want to be greedy on my postings. But I could always post another day with some more picts, for you, just let me know.

What's the white hood?

So, is there any under body aerodynamic charts? How does the transmission get cooled off with all of this air exiting before it?

The transmission doesn't need to be cooled. The temperatures that will hit the components of the transmission are significantly less than the engine itself.

the panspeed Type II has my vote!!

Doesn't the TII tranny have "fins" on the bottom to help cooling??

We have a lot of pics.....I was thinking about it and can't find a good way to test the hoods right now.

I'll do it for sure at the next race event....test the NA hood vs. the vented one on both the NA and TII. Take temp readings after one full run and then try again. Eventually I hope to get more people to do this and get some numbers going for different hoods.

DMAX or stick with a TII hood imo

Those ribs are for reinforcement strength, not cooling.

Just use my damm hood lifts and show them!

These hoods look great but in any case, I'd go for a fiberglass carbon hood. The aesthetics thing doesn't matter to me also.

interesting thread.

nice. i want that hood

Odula cf hood!!! As far as I know I have the only one in the US! lol score

Id like to see something like this C6R hood where the scoop mounts flush against the radiator. I would think with the V-mount of the stock radiator, plus the available room in the engine bay it wouldnt be that hard to do.

I agree.

I think if you had ducting from the rad to any vent on the hood it would help with under hood temps.

I figured such as well. There would also be room at the top of the hood for some vents to vent some of the hot air in the engine bay. The biggest problem I could forse is getting the hood to open, but im sure theres ways around that.

It could be a lift off hood.

I had the panspeed replica from shine, and got rid of it. The freaking hood attracts way too much attention, specially from the "kids"

Guess I am getting old!
