Maximum Engine Water Temperature

I have signed up to run Pinks at Rockingham next week. IF I have to run round robin,what would the maximum water temperature you would take it to before shutting it down. I have electric water pump and fan so I can run both while the engine is off but I'll be under my own power back to the lanes. I'm good for three runs in a row but no more. In 90 degree heat I'll be around 210 after the third run.

I don't have oil temp.
stock block making 730 hp.
A429s
13:6.1
1 16 volt battery with no alternator.


What would be the maximum temperature you would take it to if it meant the win? Only $2500 so its not worth burning her down.

For $2500 I wouldn't go over 220 but that me if you have a lot of port work done on the heads they could crack easy if it get to hot.

Your bigger problem might be keeping the battery strong enough with no time to charge between rounds. As far as water temp goes, I'd be a bit more concerned about the temp at which your system starts to puke water under the tires. It doesn't take long to fill a 1 qt. catch can (assuming you have one) when you're hot lapping.

Yes it's been ported somewhat. 320 and 260 I think.

Thanks. I was thinking 220.

I have a guy that will have a spare16v on the golf cart to replace I hope. Pinks said that we can have a "pit stop" aka golf cart , on the return road coming back to the lanes. I'm thinking...fuel up,swap bats and roll on.

Yes,1 quart jug. 19-21lb cap on radiator.

put a 32 psi cap on it. Modern aluminum headed cars don't turn the fans on till 220.... and shut them off about 195. Normal operation of the daily street ride is in the 220 to 240 range for water temps.

Have you considered an alternator? It would be of help keeping the battery up so you can cool more between rounds.

I run an alternator on my deal. With a a 12V setup I would slow charge it before a race and never needed to get the charger out of the cabinet. I recently switched to 16V. Sent my alternator to Powermaster to have it converted to 16V. Should get it back this week.

Yor gonna push the limits of that battery.....

They had a deal like that here a while back, guy who won it burnt his shit up doing so.

Better get an alternator.

Or be able to swap out a battery fast.

They make alternators the size of baseballs these days which use less than 5 horsepower to run;
In a "round robin" bracket car;, there is no reason NOT to have one.

Of course, I saw some batteries, (the size of an old 8 track tape cartridge), at the Ford Memorial Race in David Willingham's race truck which he swaps in 2 minutes.

^^^^^^ alternator, bigger, or a second puke can, and during your pit-stop have someone spay the rad with Nitrous (carefully sulfur dioxide will make you sick), or install a bottle and a purge valve pointed at the rad, shut down on the return road and spay her down while coasting to your pit stop. My purge lines point at the rad I purge in the burnout box.

Thanks guys. They are allowing us to have 4 crew members on the return road. They will have a spare battery,fuel and air tank if needed. I watched last nights race and it was a good 5-10 minutes of sitting with the car off. Thanks again.

PS. I have my 429-460 shirt on so maybe it will be on tv.

I can't think of ANY reason to NOT run Alternator. jmo

Good luck and have fun

Yes a small frame 3G one wire, they come in 70 to 120 amp versions.

I just didn't have the time or money to get an alternator back on it.

They picked the 9.73-9.76 class. I left some weights and other stuff in the car to purposely hit that number thinking out of a 8.0-9.99 field it would be the most consistent group.

I went to the finals and lost to an el camino. The fans said he jumped but Rich said no. Oh well. The battery was down to 15.6 and the water temp was up to 205 after the last run.

We had a group of guys on the return road in front of the stands with charger, air and a spare battery if needed. We may have gotten 2 minutes of charge time between rounds.

Christmas list now is alternator and more fan now.

It was 4 rounds round robin with about 3 to 5 minutes in between to work on the car.

I had a blast even though it was hectic as hell. I'll be back next year.

Thanks everyone for the advice!

BBFTTFMF!!!!!

Also saw an gorgeous falcon called "endangered Species" bright yellow. I swear I've seen it somewhere many times before. Nice ride!!!!

I know the car and the owner and both are cool. Congrats on a fine job Will it be aired on TV?

It will be on Mavtv and once they get all the editing done I guess the bigger production company's look at it. They are hoping somebody bigger will pick it up. I'm guessing it would be at least a couple months to edit and all.
I'll have to keep checking the websites and Pinks Facebook page to find out I guess.

Thanks.

He is a member here but not active. Talked to him today and the car is for sale now.
