The Beginning of Cooling Issues

[Ewheels]

I'm one of those who does not read instructions. The Race louvers are very high quality and the vendor is very responsive to questions and is helpful. My race louvers needed to be SCCA T2 legal so I have a legal size limit. RL has a specific louver for that. Winner! I just taped the outline on the car and cut the outline with a razor blade right on the paint. That left a line for me to cut using my dremel and metal cutting disk. It was super easy. I did not take the hood off. They are big and bulky and you really need 2 people. I have no friends so I put a blanket over the engine bay to catch the aluminum filings and just cut and drilled as needed. Perfect fit because of the prefect RL template. The rivets are very nice high quality. This is a really good product!

You were able to do it with a dremel and hood on car without issue??

Did the high rpm of the dremel cause any heat issues? I'm not a metal worker by any means but someone mentioned to me that using a dremel might burn the paint.

Is that where they told you to put it? Oh right, you don't read instructions.
My RL unit is 2" behind the back of the radiator, per their very explicit instructions. The high pressure area is right behind the rad, you want it up there to get that air out as soon as it exits the rad. You're not going to get maximum value out of it mounted that far back.

I've been wondering why people did that as well. I was assuming it might be aesthetic reasons. The instructions do say you can mount it farther back - it just won't be as efficient.

No the dremel does not burn. In fact the cut surface is hidden by the louver. I captured all the filings in a blanket laying on the motor and cut the hood in situ. It was easy that way. No carrying and dinging hood and no realignment needed. Race Louver says the sweet spot is 2-6" behind the radiator with the key to not put it before the radiator. So there is some wiggle room and one thing i learned about racing streetcars, aero is not significant. Yes you can put a cfd rear wing that makes 300lb at 120mph but the hot shoe in similar car without wing is going to beat you.

That's great to hear!
Copy that on the aero; I'll be doing this more for cooling purposes. Trying to maximize cooling efficiency without adding extra heat exchangers.
