go out side put some oil on a piece of tinfoil and throw a match on it .. It wont ignight.

Now put some oil in a preassureized can and spray it over a flame and it will ignight.

Certain fluids that are usually inflamable become flamable under preassure.

My buddy had an eclipse that sprung a oil leak from the turbo return line. The resulting high preassure spray onto the exhaust mani caused a huge fire.

So my point is oil must have been sprayed at a reasonable high preassure which caused it to ignight

my $.02

 

I think it is atomization as opposed to pressure - but I am sure they are related.

Smaller the droplets, the faster the oil will ignite.

Peace.

 

I was at the Putnam Park event this weekend (with my 3rd gen RX-7) and had a quick look at the S2000 that had the fire.

The RF wheelwell was pretty well coated with sprayed oil. Any fire damage was very light; nothing really was dectectable underhood because of the white extinguisher powder coating everything.

I was on track in the next run group after the S2000 was taken away, and it was clear from the large oil spill running thru most of Turn 4 that the S2K's oil loss was catastrophic; not gradual.

One of the other S2K owners there told me he looked underneath the car and couldn't see any block or oil pan damage.

Sorry, I didn't talk to the owner so I can't say what kind of warning he had before things went blooey.

Hmmm... Didnt someone recently post about the rubber gasket from a removed oil filter remaining stuck to the block when changed... resulting in 2 gaskets between filter and block. I also seem to recall that it resulted in a gasket blow out with oil everywhere... but mostly near the filter.

Did anyone actually see a flame, or just oil smoke? Engines that burn usually damage paint pretty quickly and I'd expect that some of the damage would be readily visible even with the dry chemical.

 

Andrew, I have spent nearly 20 days on race tracks and DE with the S2000 and never once have I heard of such a thing. I can't explain it, nor will I try, but it sounds like there is something weird going on here. I have run with dozens of S2000's in all kinds of temperatures and nothing, no sign of overheating or damage related to running hot.

Very strange...I'm curious what the doctor of autopsy would say happened here.

I was going to try to make it to this event, too. Unfortunately, the 4Runner doesn't get around the race track like the S2000 does and the S2000 was under the knife. Hope you guys had fun...at least you had some fireworks!

 

indys2k you have a pm about the track event.

Greg the track event is in November. You still have time, if you can get Scarlet's new engine broken in by then.

Thanks,
Bob
