Have any of you guy put diapers on your cars? Or, are you planning to? I'm going to make an aluminum tray and line it with absorbent Pig Mat because I haven't found a diaper long enough for a straight 6. Snow's all gone, getting antsy to run the car.
a custom made diaper runs about 175$ there is a guy out of Bakersfield anra that makes them. good idea makes good relations with tech but pricy. not sfi certed triple the price if you go certed. won`t be much longer until they are mandatory as per nhra
sorry the mfg. is in Arizona. they are called RUSSLERii custom fit engine diapers and have a web site phone no. is(951) 488 4200 advertised cost is now 178.00 includes shipping also on ebay
Hi. I am planning on doing the exact same thing on my Logghe car. Some events now require a diaper. When I front-halfed it I put four Dzus tabs on the underside of the frame to hold the yet-to-be-made tray. I also use Pig Mat inside the driver's compartment to catch any converter drips before it reaches the pavement. One piece of advice: make a positive retention device for the Pig Mat or it will blow around in the tray. I use two straps Dzused to the floor/tray.
out here the belly pan configuration has been talked about by our tech guy and myself and was told that it wouldn't fly because it won`t survive shrapnel impact. he said the "nylon" has a much better chance of retaining fluids from a lower engine failure
There're a couple diaper manufacturers that claim to be willing to make up custom units on order. Don't know pricing and such, just recall the ads.
Being a tech guy and talking to racers who run diapers and those that run belly pans out here I think more prefer a belly pan as it lets heat dissipate better. Some that run diapers say that the motor runs hotter because the diaper holds heat in more where as with a bellypan it will let air move around the motor and carry away some of the heat. I have seen balancers come off, rods come out the side of blocks with those running bellypans and they have held up. The PRA ( Vdub ***ociation) is starting to require their lower cl***es to use belly pans also. Had a friend with a 7 sec. mustang have an oil line come apart and the belly pan held most of the oil that drained out into it during a run.
Pretty sure NHRA allows the use of belly pans. My buds run one on their nationally compe***ive six cylinder Comp car.
Russler custom made engine diapers, great place, nice people to work with. There web site has a plain sheet that you fill in all the numbers from your engine L6 / L8 / V8 ect. Well worth the money, tech & track crew will thank you. I ran a Russler on my Chevy 194 L6 SDRA dragster, on my injected BBC NE-2 Altered and on my blowen/injected NE-1 dragster. Quality stuff. Some tech don't care for belly pans, but as with Flyer pretty sure they are NHRA legal.
I made a containment tray for my Logghe roadster so I could compete in a recent event that required one. It was an aluminum tray and I lined it with Pig Mat absorbent pad. The tech guy looked for it specifically and it p***ed.
