I have a caps tubular k and would like a belly pan but with my headers and the rules I just dont see it possible. Anyone have some pictures of belly pans or diapers installed on a non-tubbed chassis car? 7057971-k-frame.jpg (1423 downloads)

The purpose is for fluid containment and I just can't see how a belly pan can keep the oil contained at speed. I know they functionally help in other ways and don't trap heat, but I just can't believe they would hold the oil from blowing out of a big hole in the side of a pan.

Having been thru a catastrophic engine failure and the car going sideways at the 1/8th I will never run a car again without a diaper. Contact Dennis @ DRE. Great Guy to work with and the custom end product is very nicely crafted. Brett Miller 447 W9

I can take and send you a picture of mine with the heat cloth overlay later this evening if you want. Not installed on engine yet...still in box. My headers will be 1/8" away from diaper. DRE said it would not be a problem. Let me know. Brett Miller 447 W9

Just be sure the straps don't touch the header since they will burn through. 2012 422 Allstars NSS Champion 2013 422 Allstars NSS Champion 2014 422 Allstars NSS Champion

There is alot of turbulent air under a car at speed.

It used straps like a helmet plus cheap plastic snap catches like on a kid's knap sack. there are no NHRA rules or specs for those not required to be SFI approved. You can tie an old hunk of a tarp to the car with duct tape and it would not only be better but still legal home of the Sox and Martin Hemi Duster

Said he puts double layer of heat protection close to the header area. Recomended not using it on the street though do to the heat of the headers. Said his take about 5 minutes to remove.

There was no coolant standing in the pan as I made several more passes that day. It has a pig mat in the bottom held in place w/ aluminium screen. It doesnt hold in heat,I can remove or install it in about 10 minutes.It passes tech.I have no idea if it would contain everything in the evevt of a motor explosion. I do have at least 2 friends who use a simular pan on thier top sportsman cars that run over 200 mph. It has worked well for them also. 7060881-CopyofIMG_0207.JPG (4321 downloads)
