OK everyone has their shorts in a knot over this so I just had to post a funny story about the Diapers. I run S/G and ran a diaper before they were required it that class so this is what I witnessed the first year they were required in S/G.
True Story:
Was pitted in Phoenix at the Nationals next to a S/G racer from Washington State who will remain anonymous. He unloaded the car to take to tech. He pours close to 5 gallons of water in the radiator out of a 5 gallon bucket as it was the first race of the year for him after having stored the car over the winter. He comments that did not look like it filled up the radiator but the bucket was empty and he kept looking for leaks under the car and did not see any.
He fires it up and goes to tech. When he came back it was steaming hot. He lets it cool down and gets another bucket full of water and pours it in. He has now put 7 to 9 gallons of water in a big block chevy and radiator and the radiator still shows low on water. None has leaked out on the ground yet. He pulls the dipstick to see if it is in the crankcase. I have been talking to him and he is wondering where the water is going. The dipstick shows all oil and it is clean. He then decides to look inside his block/pan diaper. He pulled one bolt on an attachment strap and pulls it down. Instantly there is a river running out of the diaper. That much water makes a pretty big puddle under the race car and in the pit area.
The issue was when he drained the block before the winter storage and installed the diaper he did not get it all out and the water when it froze pushed out a freeze plug which was also in the bottom of the diaper.
Moral of the story is the diapers will hold close to 10 gallons of water and never show a leak. Also a BB Chevy does not hold that much water in the block and radiator unless it is a really big radiator.
I helped install a new freeze plug and he went on to race the weekend but everyone there did get a good laugh out of it.
