I've been involved with Diapers since they became manditory. My Alky F/C never had one. Every engine/rod failure with my Top Fuel Car(s) and since working on Jim Head's Funny Car results in and saturrated over flowing diaper. THE ONLY thing that saves an Oil Down is a correctly designed and sealed belly pan with fore and aft baffles to stop Oil Shosh. After we hang a rod out we carefully let down the belly pan that is usually full of oil along with the soaked diaper. This is the rule not the exception with Nitro Cars. Did I mention we run Dry Sumps? IF diapers were the cure all, then why are there still oil downs with the Nitro Cars? Why are belly pans manditory also? My feeling's are quite simply that a "universal" Diaper for stock/ss is impossible. The containment is too close in proximity to the headers and the risk for fire is multiplied. I personnelly will not run a diaper on my car WITHOUT an on board fire system. When they pulled Al DaPasso out of his Alky FC in BG , KY in 1992 the meat (muscles) of his lower legs were hanging off the bones like a cooked chicken. ( He died several weeks later.) I prefer for that not to happen to anyone ever again. MY point ? I hate Fire. Hit a guardrail,... spin out,... flip........NO problem .....I hate fire.....What's next? Fire Suits, and Hans Devices? Give me a brake! ...PS... for all the non Vietnam Vets out there, Go on line and look up how Napalm is made; Take a little Gasoline, Mix in a little Aluminum, add some Oil, etc. etc., sound Kinda like the contents of an oil pan?
