Send me a box and pay for shipping and you can have my old AMX 2-core radiator. It's been coated to expel heat. I think you can see it in the picture section of this forum. It was never a problem to use nothing but the fan & water pump in Arizona to get below 80 degrees; at least on cooler days. I always cycle the water pump then fan until cool, uses less amps and cools faster that way. I like to see no more than 100 as I pull up to the water box. If it shows 120 on the gauge, I'm not happy. I've gone to aluminum as allowed in SS class.

Do check out the "Cool One" as noted by Rod Green. Hurry as pricing is going up $100 soon. If you want one, let me know and I'll try my best to make sure the price is locked at the current price.

I thought Grumpy Jenkins always said a hot engine builds more HP?

In an "ideal" situation you would want the shortblock and the combustion chambers hot and icicles hanging on the intake!

I think when Grumpy was quoted oil was typically on the 20-50w range for race engines.
Now 0w is not uncommon.

They were cooling his Pro Stock stuff down a couple of years ago just like everybody else. When that book came out everybody I know that tried it slowed down. He said he had a switch on his shifter that turned the water pump on in 2nd gear. We all went back to cooling them down. The all aluminium engines don't seem to care, and many actually like to run above 180 F. The LS1 is a great bracket engine because it makes the same power between 180 and about 210. I cool mine with a seperate battery to run the water pump and fans. Like Jeff mentioned, we often take it to the staging lanes to cool down for heads-up races.

How many of you guys have drained the water in the pits between rounds and added COOL fresh water to cool the engine better

On all of our stuff filled with Hardblok the water cools down alot quicker. The oil temp will run a little hotter but we have no problems from Hardblok

I can tell you first hand that 10 qts over 5 will slow you down 3 tenths and almost 4 mph, Did it ,by accident, @ Indy a couple years back.
