The Big Fat Track Car Cooling Thread

[shogun32]

Damn, I wish I had seen your setup before I bought my giant intercooler and the

oil cooler. My intercooler comes forward and extends up to about level with the tip of the crash bar, making it virtually impossible for much air to reach the lower part of the rad. And I'm probably compounding my problems by placing an oil cooler in front of the rad. I'm tempted to undo this and start over :(

granted I didn't test mine under HPDE conditions but this is all the same stuff I did to my EB. I think you need to change out the crash bar with the round one like you see a few posts up and that will dramatically improve access to air.

The big IC was very effective. I didn't box anything. If I buy-back my EB I will definitely do some updates to it.

I noticed that thinner bar. However, unless you cut open the bumper cover, I don't see how it's going to let more air get to the rad?

you can only cram about 30-35mph worth of air thru a radiator so completely open front is not important. What you don't want is air just spilling over the side when it encounters a semi-permeable surface, or causing all kinds of turbulence in front of the radiator face, nor 'shadow' areas where air can't actually get in - eg. right behind the crash bar.

Regarding the oil cooler location:
It’s why I went with the Harrop oil cooler
It seat parallel to the ground

Looks very nice ($$$). Unfortunately, they don't offer one for an Ecoboost motor.

good gawd, that price! We need to beat up @SteedaTech to kindly put a system together using the various parts they already sell. I've emailed them a proposal but no response...

They have an office in the USA and me and my friend john were the 2 first customers
We paid about $875

how about taking a 2" hole saw and swiss-cheezing the fan panel?

You can i guess but still not the same of only fan. Ifncar is daily i would keep the shroud. Shorud really work when car sitting at traffic.

because it's causing a negative pressure... So isn't the car running the fan constantly at track? Is it jus that the airflow with fan is not nearly enough to to keep up with what is possible if the shroud were removed and ram air was doing it's thing?

Grr.. In a bad mood....

Am I wrong to say that the car was not made to withstand temperature impacts when under harsh conditions?

Did what I thought would do a lot to avoid overheating for just a chap that's trying to have some fun.

(Lizardskin thermal coating on intake parts/Exhaust wrap galore/ Hood vent upgrade/Front fascia upgrade/Mishimoto Reservoir/Uh... and a diffuser! Like that matters!)

Sorry, in a bad mood.

do you have metrics on effectiveness? eg. boxed rads were worth 20F in coolant temp reduction?

With motorcycles esp dirt bikes the rads are 'boxed' (sorta) and they use vanes to also cut down on the turbulence in the inlet area. I'm tempted to try adding vanes to a boxed setup for giggles if nothing else.

How deep of a box is that? about 2 inches? Have you tried ducting the fans?

No metrics. Only thing I kept track of was how long I could drive flat out for until temps got into 240’s and then I’d need to pull rpm.

The most effective mod was definitely the boxed rad, and the more effort I put into completely sealing it the better the result. The hood vents were installed after the boxing in, so can’t say how it would perform on own, but based on experience of fellow track guys, it seems that cooling won’t be effective if airflow can bypass the radiator.

Deepness of box is roughly from side edge of radiator to just behind bumper bar

When car is running you don't need Fans.
Is when you stop.
En fact many race cars don't even have fans. And no one has shroud.
The less barrier you have the more air flow you got at speed. Shroud does a great job when is the fan pulling air.
Thats also why the OEM shroud has some windows/flaps opening at speed on the side.

Here some real data.
I like what racelouvers does. I have vents everywhere cause i really like the science behind.

Fans are only common if you have to do standing starts, because spending a couple minutes gridding up and can overheat the engine at the worst possible time, so we agree there. Almost every purpose built racecar has proper ducting to the rads, though. Good ones address entry and exit flow.

When I spoke to them they only had version for RHD, do they have a LHD version now? Who did you talk to over there? I talked to them last January and they said they were having too much trouble with an LHD kit and were probably going to abandon the project.

@db232, did you ever hear from the USA office?

thanks for the citation. Given that data (mere 5% improvement with vent over no-shroud) I will be swiss-cheesing my fan shroud instead, saving the money on vents and extra hood, and spending a veritable fortune ($20) on boxing the radiator(s).
