What would be the running approx. time in minutes for an engine with a set these sold heads?
Lets say a mild with todays standard, SS Cross Ram Hemi (12,5 comp)…
Thank you for taking the time.
 
Need more info...............Do you you mean long can the engine run without water or do you mean how long an engine will last with those heads>>
 
Yes, I guess question is a bit silly. I fully understand you don´t drive around in the pits and keep the engine running while waiting for your turn to do the burn out, but are heads super sensitive. I mean you need to keep shutting engine off unless you don´t need to move, or heads instantly get too hot?
Just a little general speaking from someone who have run these type solid alu heads...

I'm sure there are some drag racing experts on this site. But most of the heat builds up as you're staging and doing burnouts....by that time the engine is already warmed up. Then you go full throttle for a 1/4 mile and it gets intense!! Even the hardest drag racers have at least an electric water pump to keep from ruining the engine. I'll step aside and let the people with experience speak!! treblig
 
Well not an option for me really.
Saw this new never used old 90´s style PS heads. Facebook Hemi Trader.
Just did some figuring and wanted to hear some more how these type of Heads work in actual racing...

You run alcohol; it acts like a coolant as it will adsorb heat as it vaporizes in the inlet tract; think top alcohol dragsters/funnycars
You don't drive the car up to the staging area, you tow it
you don't fire the engine up until it is your turn to stage, then you begin to build some heat in the engine, lots of practice here to get the dance right of the optimum engine temp for launch

Yes, I was a bit sceptic when guy says Pro Stock stuff from the 90´s, but maybe back than… well I dono…
Thanks
 
I will say this...........I was not aware that Pro Stock ran billet heads, though it is nothing new, there were people running billet heads in the early to mid 70's
