Jon.. You Can Tell When You Put Down Too Much Water To Fast When You Can't Keep Your Motor Running. I've Always Seen A Tea Spoon Used Instead Of Trying To Pour It From A Bottle. John

Re: ping under load
Dang, i bet the oil companies love people like you. And back to the water subject, what's the big deal? Haven't you ever heard of water injection systems?

Yes, I have heard of water injection - we use it in racing engines at Reno in the Sport Class. It cuts the life of the engine by over 50% and the bores look like hell when we tear them down. The Merlin aircraft engine (P-51D) had water injection, and if it was used to exhaustion (about 8 minutes I think, but I'd have to look) the service manual called for immediate replacement. Hey, it's a difference of opinion I'm not going to change my mind based on my experience, and you're not going to change yours based on your experience. It's all good |

Re: ping under load
Why would you use it in a racing engine? Racing engines are supposed to be built for racing only so they are tuned to do just one thing. Do they have to run under some special rules in that class?

Water injection is used on racing engines that are on the ragged edge of detonation by design. On an air-cooled aircraft racing engine, manifold pressure of 25-35 inches is normal (test flights, cross countries, etc.) but during the race will run at 60+.The first time I saw 60" on an MP gauge, I thought I was dead - seeing this on a stock light aircraft engine means parts will soon be departing the aircraft Same thing on the old warbird engines with water/alchohol injection - about 45" of MP, going to 60 or 70 (or I hear in some cases, 90"+) when the water injection is used. There's a safety wire on the throttle that you push through and break to get into "WEP" - War Emergency Power. Some video games even replicate this - if you use "WEP" for too long the oil temp goes up and the engine fails. |
