engine diaper
 

im sure you guys know starting next year all s st cars have to have a diaper. my 70 chevelle has a stock front suspension and front to rear engine placement. its a bbc with a moroso kickout pan with a scraper and windage tray.the pan had to be modified with boxed enclosures where the inner tie rods would hit the pan when against the steering gbox locks. also, the draglink is within .060 of the pan. my big question is how i get a diaper to conform to the pan where its been modified for the inner tierod clearance. looks like i will have to make a fixture and cut the center out of the drag link and fab a new piece thats lower for more pan clearance. this is a pain in the ***. i should just build a chassis car i guess:mad:

Sorry the SFI spec is to crazy for me to spend the money to certify a unit and compete and make any profit.I can make a trick piece out of kevlar that would hold everything but the spec testing makes tou use too many layers and you get too bulky

Re: engine diaper
 

Thanks, Dennis, I understand.

Re: engine diaper
 

Dennis does VERY good work and stands behind it. He built a custom diaper for my Chevy II with a notched pan for the drag link. It can be done...

Re: engine diaper
 

I went with trays on both my cars. They are held on with a on couple dzus's and dont hold the heat in the engine or get in the way of any of the steering. Plus were cheaper than any diaper and dont get caught or torn in the flexplates. Food for thought.

Grant it, a pan/tray may be easier to work with, however I have a tuff time beliving that the tray can contain the fluids without being sucked out of the tray by wind drafts. In the case of a diaper, it's required that it made high enought to meet the block/head mating surfaces. And a tray I belive are only a few inches high........will they even reach the bottom of the pan. ?

Another note, several years ago, WJ was testing pan/trays. His position was " it dosen't work"

Look at the attached pic, and think about it !

Please Be Safe...........

Re: engine diaper
 

with a stock front end i think a pan would be even more difficult than a diaper. if you went frame rail to rail the suspension is in the way plus you would have to mount it low to get the 2 in minimum lip . as much as i like my car im thinking about building a s st chassis car for lots of reasons this being one of them
