Cool Shirt- How in a PFM?

[janton9736]

I got super hot on grid in my PFM last year. How do you use a cool shirt in your formula car? In my race 944 I have a large ice water box with pump to connect to cool shirt, works great! Nowhere to put that thing in the PFM.

Need your suggestions please. I won’t usually have a crew to help me with a fan etc.

thanks!

You need a crew with an umbrella.

Coolshirt has a gokart system where everything is contained in a soft nylon bag.

I have no experience using one.

Cool shirt ice packs is probably the most practical but it would be possible to put a small cooler in fromt of the RT side rad with some creative plumbing or if money is no object there are setups like we use in Indycar. Big bucks but it works

In addition to the soft ice bag with pump for karters, the "cool - a - clava" works really well too.

im wondering about your plumbing suggestion. If I were to drill a hole in the cockpit for the chiller hose would the stresses cause thE carbon finer to crack? No, not an unlimited budget. What does Indy use?

Yeah.......DON'T DO THAT.

Agreed. But the PFM has a factory hole in the left side that has cables and electrics running through it. I dont know how large the cooling plumbing people above are referring to is, but might be an option.

Definitely do NOT drill a hole in the chassis. It would have to route through an existing hole. Ice pack based cool shirts are by far the most practical
I can't think of the system we use in our cars off the top of my head, I will check tomorrow,
It is multi-thousands of dollars

As stated in the other thread, the system we use is from Rini Technologies

On hot days i put my underwear and suit in my RV freezer. Just before I belt up my wife drops a couple of bags of blue ice gel beads down the back of my suit, just above my kidneys. Lasts about a half hour.

I'd chill my helmet too but not enough room in the freezer.

Helps to have a couple of pair of underwear so the sweat doesn't freeze.

1. Umbrella
2. A little dribble of ice water down your collar
3. Don't put your helmet and gloves on until the 5 minute is called on grid
4. A battery powered fan (to match your other power tools) is fantastic. Even if you are alone on the grid, a worker seemingly always is glad to set it aside and you can get it after your session.

Battery powered fan? Not. Bad idea!!
