sorry - no engine bay temps.
9k - an auxiliary radiator really isn't the direction I'm looking to go on this one - interesting thought though.
110* track days really test my sanity though - maybe simply avoiding that is the best option. I have no issues running hard the entire day at 100-103* temps, which isn't bad at all... Another rx8 was there running similar times with a vented hood as well (had another aftermarket radiator), and was bouncing around 230-235* during the 95* sessions.

Yeah I mean in these high track temps we see here, most rotary guys just don't run much in the summer and if they do it's only during the morning sessions.
My car will be undergoing a transformation for track use soon and we shall see how the current system holds up. Right now I can't get it past 220F (and that is only in rare low speed situations) no matter how hard I beat on it in the twisties. I have the turbo on it's own coolant circuit with a heat exchanger, a secondary radiator mounted where the stock second oil cooler was, a large second Behr oil cooler center mounted, FAL fans, Mizu dual row radiator, and I run Evans.

haha that sounds much more complicated, but sounds like it works!
Ironically, I had more heat issues going up and over the Grapevine coming home (30-50mph slog at that time going uphill for a few miles in traffic). It was about 105* on the Grapevine at that time, but with traffic, I think the car just wasn't getting enough air and was getting everyone else's recycled hot air. Temps got up pretty high for me and the Lotus I went with. Highest temps we saw all weekend in our cars, haha.

Hi,
I have a S1 2006 RX-8 NA with a lowered trigger temp for the cooling fans and will be installing a mishimoto thermostat.
But I was also thinking about venting the engine bay... What to you think by opening up the stock fake vents on the fender behind the wheel arch?

Engine and water temp reduction
Okay, I decided to give these guys a shot. Thought I would post the installation and finished project in case anyone is interested. I purchased the hood louvers from Good-Win a couple weeks ago and will give them a test at Laguna Seca on Monday. To be clear, I could care less about the look (actually dont care much for it), but Good-Win and Singular claim a material reduction in engine and water temps. We'll see, my 8 runs stupid hot. Just started the installation tonight, but here's where I am so far:
THE KIT
Pretty good kit. The louvers come unfinished so they need to be painted, powder coated, etc. to keep them from rusting. I went with a good old fashion spray-can finish in the same color as my car. The kit also comes with a decal template (for cutting), rubber trim, mounting hardware, and removable gurney flaps.
THE SETUP
The first part entails accurately measuring the hood to properly center the cutting template. This is not hard, but as usual measure twice and cut once. Unless you like removing decals and/or having a jacked up hood. Once you have everything properly measured just apply the decal template like you would any other sticker. By the way, we all know each sticker is worth 5 hp at the track. Trust me...more stickers = faster. Just ask a Honda guy.
You also need to remove the head shield from the under-hood. This is where you will realize you are not just cutting the top of the hood, but there are two layers that need to be cut. Damn it, surprise #1. Go back to the store and get more cutting wheels. As for cutting, I will be using a dremel tool, but a cutting wheel would probably be way faster.
Tomorrow I will do the hood cutting...and will surely end up with many cuts on me too.
