Re: Controlling the water temps on the track

I put them right behind my oil cooler and forward of the strut towers to be in the low pressure zone. This is with a Wizard radiator and an RX7 oil cooler in place of the intercooler.

I'm gonna try the louvers.

I think the radiator is fine, just need to make sure that you have good ducting from the front fascia to the radiator and then a path for air to leave the engine bay.

Lemming, Size and brand of oil cooler? Thanks. Mike.

It's a stock griffin unit, two row. Can't remember the number, but I'm pretty sure that info is in my build thread.

I just put louvers on my, mostly track car. The drop in temperature is dramatic, in Florida temps I went from 230f water temps to needing a thermostat! I opted for max cooling and installed 33x7in louvers right over the block hugger headers I swear I could cook burgers and dogs on those louvers! I just swapped engines from a 350 to a higher compression 383 so its dumping a lot more heat. I have an oil cooler in the nose panel, renegade/ron davis radiator and never had problems with the 350sbc.

Pics of louvers and where you got them from?

tooms351 Sun Sep 28, 2014 4:06 pm

Of course the scoop helps, I was over heating at idle and low speed and stop and go traffic, bought the louvers from run cool hood louvers, really nice people to deal with.

tooms351 Sun Sep 28, 2014 4:53 pm

Well cant figure out the pic deal but if you want pm your email and ill try my hand at that!

<--- See: Mine are from run cool as well, but are the shorter/wider 17/11" louvers

I was looking at your hood, I bet those vents made a difference, what is the oval in front, ram air? Whenever I stopped or slowed down the temp would start rising, I would rev the engine, water temp would drop 10f then immediately start rising to 230f thats when I shut it down, so I figured it was heat sinking.

tooms351 Mon Sep 29, 2014 7:30 am

I couldn't post pics from the phone but was able to post as my avatar, this is how the car looks now the plan is to plastidip the hood or a flat black line down the middle of the car.

Not ram air, but a reverse scoop for removing air immediately after the radiator. The vent system on my hood came about when I was running a SC'ed 968 engine that put off a tremendous amount of heat (more that the LS1!).

Tim,

Where'd you get the reverse scoop? Looks like it'll help create more hood clearance for my throttle body as well as scavenge from the radiator...

I bought that a few years ago and I cannot find the website. I believe they were called CarbonX, and my guess is that the name got them in trouble (carbonX race wear) and they changed their domain and company name.

You are correct, the placement is such that my throttle body does not hit the hood Very Happy

docwyte Mon Sep 29, 2014 10:51 am

I'll start looking. The louvers helped lower coolant temps too? Maybe I need to add those as well...

kevin924kevin Mon Sep 29, 2014 4:40 pm

Doc, go to IFC racing they have a really nice unit to sit down in the front of the hood that will allow a lot of hot air out. Part # 968 TS really nice hood vent.

Google Carbon Trix, go to site called road race motorsports, menu on the left at bottom says
vents and air ducts. First page under that heading has the ducts that lemming has.
Ran the same one when I raced a 16V Turbo 944. Main reason was, you guessed it,
throttle body clearance.

They sure are proud of their products based on price Shocked

That rear wing/spoiler they are selling for $900, I did one years before for $69 (including shipping from Ebay). Don't get me wrong, I'm glad to see more options out there, just saying $69 vs. $900!

EDIT: just checked Ebay, you can still get trunk wings/spoiler for $69 shipped, all you have to do is modify the base.

Now back to your regularly scheduled program!

Those louver panels are $299 each. Ouch. Don't think I need carbon fiber, fiberglass would be just fine. Any vendors out there have them in fiberglass?

tooms351 Tue Sep 30, 2014 8:57 am

Mine are aluminum, $179 or there abouts for 2.

tooms351 Tue Sep 30, 2014 9:02 am

http://www.hoodlouvers.com/# sorry $215 for 7 1/2x33 plain kinda pricey, but they do get really hot.

Had a hard time finding them in steel so I could weld/blend them into the hood.

Steel ones that I used.
