Cold engines? Are ring wear and engine longevity not a concern?

Looking over data of about a hundred runs my average has been about 130 degrees at the start and 155 thru the lights. Of course the temperature rise is dictated by many factors including fuel, carb settings, timing, water flow, type of material for engine components, etc., etc. Hope this helps.

Just warm enough to get any cylinder distortion out
of the cylinders and the piston up to diameter, cold
intake charge and oil good and warm

We try to have the drag radial car stone cold. Usually about 130 at the end of a run.

I would think the hot oil would help the surface areas of the bores to stay warm and not wear as much as a dead cold engine.
after a day at the dyno, my best pull of the day was when they did 3 back to back pulls, and got the oil up to around 170, then dumped the water, and cooled the block, did the last run with oil at 165 and water at 120, and it was the strongest pull of the day.

Quote:We warm the car at the beginning of the day and get the oil hot. The rest of the day, we want the water as cold as we can get it. In the process of building a chiller to cool it between rounds. Planning on taking the water pump and radiator out of the car. It only makes about 40 degrees during a run and has no fan now. With the chiller, it won't need the radiator.Quote:even the oil? or do you heat it?

I was talking to a SS engine builder the other day and he said they chill the water before pushing to the line. They try to keep the water temp below 100 degrees on the starting line (that is after the burnout). Have to use a 0 weight oil. I've never tried any tricks like that myself but I do know that if you want to make some extra power on the dyno you just crack the valve and let more cold water into the engine. Sometimes if you look at dyno sheets you'll see that people are running the engines at 120 or 130 degrees. I usually run all of my tests at 180 so I guess I'm giving up about 20 or 30 hp.

Very good info 
It makes me wonder why my 10.99 run came after a back to back pass @ 200 degrees?waqs running 11.0s all day then came up the return road no
one in the lanes so I staged at 200.

So maybe those old motor home dipstick oil heaters could come in handy at the track after all!!
