Lots of overheating questions on here, it must be summer!
My car will run 180 - 190 the entire race, heat race or feature. On the way in to the pits, it starts heating up. I usually get to my pit stall by 210 - 215 degrees. When I shut it down, it gets up to 230 - 235.
Before the heat and feature, I pop off the cap, fill it full of water, rev it up some to get the maximum amount of water, and then go run the race. On the track, some of my crew can see some water coming out the back out the overflow. So when I idle in, I don't have as much water in the radiator and it starts getting hot.
The cap was brand new at the beginning of the year. It is a 22-24 lb. cap. I also had to put ceramic seal in at the beginning of the year because of crack in the valve seats. Could heat be caused by this leak starting to open up again? I'm wondering if I should add another bottle of the sealer.
Should I purchase a 22-24lb cap, or a 29-31lb cap to replace the one that Iím currently running?
My timing is set at 34 right now, I've heard you should increase by 2 or so degrees once it starts to really heat up outside to help prevent detonation since the air temperature is so high.
I also have not dropped down my jets much at all from when it was still pretty cool out. Can a rich fuel mixture of Alcohol make the engine run hot?
Iím running a 180* thermostat with 2 3/16Ē holes drilled in it. I canít get it warm enough, fast enough with a 160*.
I realize 230 is not that HOT HOT, but when your engine never gets over 215 or so, it starts making you wonder what is going on.
