Engine Chill Down Unit
 

I apologize if this question has already been posted. Does anyone have experience(s) with an engine chiller (for cool down between rounds). I'm interested in making a purchase but I'd appreciate input from Class Racer members.

You're right, lots of threads; just use the search function in the forum toolbar and search for chiller. This is a good one...

I got a kick out of Tom Sheehan's 'pics from Indy' last year, chillers were thick in the lanes during class, believe last year's Indy was the max number I've ever seen.

I've seen plenty of homemade ones, but all of them use ice. Has anyone built one that doesn't use ice?

Also, what kind of pumps are people using? Most of the ones I'm finding are 12V but we would like one that we could plug in and not need a battery.

Andrew-- Look at Ralley Bob"s link. Sounds like what you are looking for.

Rob Youngblood at Advanced Clutches sells an affordable chiller.

Re: Engine Chill Down Unit
 

It's exactly what I'm looking for, except a couple grand too expensive! I was hoping someone had made one themselves for a more reasonable cost and was willing to share their idea.

I use a 110v pump that is made for evacuating flooded basements. It draws from under its base, and will maintain suction to 1/4 inch. It gets submerged in a 5 gallon bucket of ice water. It plugs into a generator that we carry on a garden wagon along with in and out (or cold and warm) water containers.

Our check valve comes from a basement sump pump as well.

Re: Engine Chill Down Unit
 

got a number for that check valve? I live in a part of the country that doesn't have basements, so I'm pretty clueless on those.

Tony are you comfortable sharing how much you picked up using the "cooler"? Inquiring minds want to know.

Just purchased one from Twist & Shout Racing. Advertised in dragster. Also, I have know Paul Pittman for over 20 years. The unit is insulated, powdercoated, 110 volt, with top shelf hoses and connections. The unit is $1,250 plus the in hose fitting. You need to ask him which one is needed for your application.

X2 on that

Re: Engine Chill Down Unit
 

Does this one have to have ice to cool?

Re: Engine Chill Down Unit
 

Is this an actual chiller that doesn't use ice or just another circulator?

Re: Engine Chill Down Unit
 

To answer Matt, Garrett and Joe D., I thought it was worth .07 at the Dutch Classic last year, but only about .03 or .04 at the Atco National Open in May of this year. Those are the only two times I've used it in competition. But this is only based upon what my prediction software thought it should have run, based on prior heads-up tests.

With ice water I can get the out-coming water down to about 70-75 degrees, while keeping the oil hot, using about 5 gallons of water and 2 large bags of ice.

Getting any cooler takes much longer, not to mention a couple of fresh loads of ice. And then when you cool it too long, you start to see the oil cool down, which is not what you want.

The label says Parts 2 O, part number appears to be FP0026-10. I found it in stock at Home Depot. It will fit inside 1 1/4" and 1 1/2" hoses.
