It aint ugly I think this is a good example on how commercial tuning industry has become..."lets hurry and make something first to make money"
But like I said it aint ugly... it's FUGLY. Seriously, we own evos not "LANCERS" So I think you might want to check with them. They're a little more prone to these things....

 

Thanks. We are a little more than a shop. We have built SEMA cars for Mitsu for the last seven years. I have had the V.P. of Mitsu, Jun Asami sit in my office! I have never been in his. THat kind of comment is pathetic. A mod can close this thread. Too many people that jump way out of line over a hood.

So much for wanting feedback, eh?

If you can't take constructive criticism, why post in the first place? You guys come on here and make a bunch of claims and have absolute zero proof to back it up. I'll be the first to admit that I'm wrong in my speculations when someone can clearly demonstrate that my position is incorrect. Similarly, if someone can put forth a solid alternate theory, I'll go back and get the proof to figure out which side of the argument is correct.

Fragile and/or oversized egos FTL.

Please keep your responses on topic. DirectorSe7en, you've made your point.


Right idea, but your understanding of aero isn't quite right. The bump creates a high pressure area in front of the ridge and a low pressure area immediately behind the ridge. At speed, air will attempt to get to the low pressure area but will end up dropping down a few inches behind the ridge - right into a well placed duct.

NACA ducts eliminate the need for a bump by creating an inherently low pressure area at the back side of the duct. They offer quite a bit of intake capacity without the drag created by ridges (thus why F1 teams avoid them). However they require more volume inside the engine bay than a ridge and hole, so for most aftermarket solutions, they don't work too well. They also have to be placed in a relatively high pressure area of the hood to work best (reference dcorn's pressure map).

Is RRE's hood better or worse? It's hard to say. It'd be easy to do A-B-A tests on underhood temps to validate his claims.

 

Thanks WSB, I got the report, but didn't know where to start.

 

If you are trying to use it for an air intake, then you are correct, you could use a ridge to that effect, although I believe a NACA duct is more effective.

However, the Mitsubishi hood vents (not the center NACA duct on the X) are there to extract air from under the hood. Creating a low pressure area above the vent helps to insure that air is still evacuated from the hood when the car is at speed. In other words air that enters through the front of the chassis, goes through the IC and radiator, and then has to flow around/over/under the block is provided with an escape route through the hood vent. It's a similar idea to the NSX-R hood, except executed for a front-engine car.

You're right. I was thinking of an alternate way to manipulate airflow to do air intake. It'd be interesting to see how much of a pressure vacuum you'd need to generate (via ridging) to ensure the hood outlet was a lower pressure than under the car (where heat is normally vented). Of course Mitsu used a lot of underbody trays so that may not even be a valid comparison on the X.

 

That's exactly what I'm asking for ... proof. Just because a company has built things well in the past is NOT PROOF that their new product is just as good or better.

If we all lived by the "they are a straight up shop and have been doing this for years" theory .... we should then all be driving Ford Mustangs ... because Ford is a straight up company and they've been building cars for a very long time (Edited out the part about Ford being first ... see post below for reason why lol).

 

Mercedes Benz has about 15 years on Ford...

I understand your point. Your way of making it was a bit on the blunt side though.

 

lol ... oh my bad ...

Then we should all be saving out money so we can buy and drive MBZs lol.

Thanks for understanding my point though ... even if it was delivered bluntly

 

So is Perrin on the right track with their analysis, in this thread? https://www.evolutionm.net/forums/sh...d.php?t=331611

 

Here's the hood installed on a lancer with an Evo X bodykit. The point is to notice how flat it looks....

 

What part of "you've made your point" didn't you get?

 

This is a tough bunch. My Ego is fine though. Easy for all to make points without supporting their theory. Mods are seeing it. I am pretty much done with the thread. Some like it some don't. I'll decide what to do in the next couple weeks. To the civilized folks, that for the input even if you thought it was ugly.
