Obviously, if one is to run lap after lap etc, one would not only want coolers, but one would also want electric fans and electric water pumps to assist in cooling down the engine between runs. Don't you think Erik? But then, I suppose even that should have a quailifier for some, because some race engines get thorn down between races, damn it's tough to be thorough. Correct me if I'm wrong, but dragsters do not have engine oil coolers, or even engine coolant and rads, yes?

Be that as it may, I merely said that a few second burn down the track without an oil cooler is not as critical as one driven down the streets through all sorts of traffic and whether, which might have an effect on longivity, don't you think?

I think what the question really is begging for, Erik, is an answer as to whether to bother having coolers on a street driven engine. What say ye?

And here too we could go on about a sbc 350 engine producing only 165 h.p. verse one producing 500 h.p.
It really depends on what class of drag racing your in.A lot of dragsters on (gas) use not only a rad. and a fan.A lot of dragsters that run a power glide use a frame mounted or remote mounted tranny cooler.Some dragsters on (alcohol) may only use coolant in the block it's self.Some (door slamer) cars will use an oil cooler with a fan because they may sit in staging for awhile before they run.
