Ok, we had some problems with this last year, and didn't really have a good solution. There were times when say we had to run in the B main, and then just a few minutes later turn around and run the A main. What would be the fastest way to cool down the car? I would think it would be to get cool water into the motor, but I haven't come up with a good way to do it with the motor hot (220-230 degrees on the gauge). We cool it down with water bottles, but I would like to get a little more heat out of the engine. Any ideas, or would introducing new water into the system be bad. Thanks.

Hey rickb33, do you know where to buy those extinguishers and how much they run?

if you want some of those fire bottles they had a couple on ebay the other day do a search for imca and it will come up if it's not over was at 9.99 for one and a spare bottle with no top. as for a way to cool it off fast we have a dump valve on our thermostat housing that we open and it dumps all the water out then just run some cool water back thru it and away you go we just use the housings that have the sending units on it and use some plumbing fittings and a 3/4 in valve with a hose pointed down to the ground it also helps to get all the air out of your cooling system when your filling it

Most times I am all alone in the pits so I use a spray bar system. It is a 5 gallon plastic gas can filled with water connected by hose to a electric fuel pump which is connected by hose to a bar located over my radiator. I don't use it on the track unless its absolute must.

I like that idea ryan. What type of a fuel pump do you use? Any problems with it seizing due to running water instead of gas? Sounds like a very interesting setup. Your tech people don't say anything about that?

Grainger sells a TEEL brand 12 volt water pump that works great. It is around $30. It has 3/8 NPT threads AND garden hose threads on it. We use use it as a water pump on a dragster. It would also be ideal for this application.

Hey, when you have to meet minimum weight at 3400 lbs, it's no big deal.

3500 lbs here, its proabally only 40-45 lbs at the most usually keep the can in the back next to the fuel cell. Proablly 1/3 of the guys have them. It doesn't help you go faster so tech doesn't care. Funny story I have been racing going on my 4th year and I was at the local speed shop and started to b.s. with the tech guy when he asked me and I quote "Do you race?" had to bite my lip so I wouldn't laugh. Back to the subject at hand. I have ran the generic fuel pump from Advance for a year now and haven't had any trouble yet. I beleive it was the higher pressure model $20-$30 or so.
