A car I'm working on is nearing completion with the motor already set in stone as to the internal workings of it. Here's what I've got. A Honda v6, J32 variety, on gas, boost and nitrous with welded heads and the block having no filler what so ever. The heads will have water running through them to aid in cooling. The car will only see startup at the starting line, burnout, stage, run and shutdown. Prolly less than 5 min hopefully depending on staging games. Any thoughts on past experiences would be enlightening. Thanks in advance.

 

ive only heard of alcohol or nitro stuff running dry. but never heard that about a gas engine.

 

Methanol/Alcohol with a water-air intercooler aids in cooling. Gas setup not too sure about that.

 

oh i forgot.... the air cooled vw's and also some small engines(motorcycle's/lawn mowers). no coolant running through them engines.

you could always put a head temp sensor on it, and do some testing

 

They also have fins on the heads and motors to disapate the heat.

 

With the water going through the head I'd think it's something worth trying to begin with instead of tearing it all down or running methanol.

 

you built a car for the modified class, and want to use gas? why not just use methanol? any reason

 

when I started this under the old nhra xplod rules, you could add any number of power adders using gas only, I like nitrous as an additional power adder. but with that story behind us, i stuck with the program i put in place, thus using gas.

 

People do this all the time with the mitsu engines, they can run low-load (idle) indefinitely. The block heat just leaches out through the oil and conducts up through the head. No freeway driving allowed though.

 

The air cooled vdubs and motorcycles also run oil coolers as the oil and fins on the blocks are what dissipate the heat. I owned an air cooler bike and it didnt like to sit in the heat/traffic very long, would bog big time till it cooled back down
