TAD/TAFC changes for next year helmet shrouds, pads, belly pans, etc.

Has anyone read the part about the flame retardant, oil absorbent liner that is suppose to be in the belly pan! Don't have a clue what is going on with this.
Its in the new rule book!!!

 

jeff do you know how much it cost for the kit are to have it done by mike

 

Just a quick update on the rollcage shrouds. I've got one coming from Bret Williamson. He has made and got approval on the carbon shroud. They come in two pieces, but I'm going to make a 3 or 6 piece out of mine. I'll keep you guys updated.

If you need to get in touch with Bret his number is (408) 848-6333

Only 36 days left.

 

If it's approved, how can you change it and expect it to still be accepted,

 

His (Bret) or any companies shroud is approved for the process of making and structural design, not the install. An approved 2 piece design that is not installed properly would not be legal. I hope this helps.

The way I understand it is that I can make my own from carbon fiber, but would need to send a sample to NHRA and have it approved.

 

Oh, now I'm totally confused, sorry I asked.

 

Other than here, I haven't seen this anywhere, rulebook or otherwise.

"EGT Junction boxes will have to be securely fastened to the header."

Mine aren't, and neither are many TF/FC's. You have the orange wire in the harness carrying it plus 4 leads from the header probes wound with stainless steel. Mounting it would be redundant and is not necessary.

 

I'm planning on making our new belly pan this weekend. Has anybody done it yet? I REALLY don't want to have all that oil in the driver's compartment. I was going to put a bulkhead in front of the motorplate, behind the oil pan. My other thought would be to make a one piece pan all the way back, but still weld a bulkhead in front of the motorplate. Any oil running down by the frame rails would still be able to get to the back, though. Any thoughts? Pics would be great, if anyone has some.
thanks

I agree with you about the oil in the drivers area. I am planning on a bulkhead between the oil pan and the motorplate. Where else would it go? But I am also planning on a hole in the floor under the transmission to allow any accumulated fluids to escape rather than fuel a fire between my knees. My current belly pan has a hole in it so I am staying with that idea. Does anybody else have any better ideas? Dave Germain

 

belly pan misprint

According to Bob Devour, the way the belly pan is described in the rule book was a misprint. I wouldn't go building one to go back past the motor plate until this is clarified. He said they copy and pasted the description from the dragster which could have a one piece pan clear to the rearend. You have to make the sides go up to the top framerail, the front and rear bulkheads must be a minimum of 4" tall, and the front bulkhead must extend forward a minimum of one inch forward of the front lip of the bottom pulley. Bulkheads need to be "coved" inward to promote the oil remaining in the pan. A "hole" to allow the fluid to escape completely negates the purpose of the belly pan and is likely to not pass tech.

Just my two cents, if questions you should call bob devour. his number is listed in several previous posts on this thread and the one about the seats.

 

Belly Pan Misprint

We talked to the tech dept and they said it is a misprint on the belly pan. Pat at NHRA said to follow the same specs as nitro funny car. NHRA is supposed to put a revision on the thier website today notating the revision.

Doug Gordon

 

here's the revision:

Delete paragraph and replace with “Engine oil-retention pan mandatory. Minimum material, .050-inch aluminum or .040 carbon fiber/Kevlar. Pan may extend rearward of the motor plate to capture oil from rear main seal, but no more than 3 inches rearward of the motor plate. Pan length from motor plate forward must extend a minimum 1 inch forward of the front face of the lower pulley. Pan must be either a one-piece design or constructed as to be sealed as a retention device to retain oil. Must have minimum 4-inch high bulkhead on front and minimum 2-inch high bulkhead on rear for oil during acceleration and deceleration. Bulkheads must be “coved” toward oil pan to assist oil in staying within the confines of the bulkheads. A non-flammable, oil-absorbent liner mandatory inside of oil-retention device.”

are the liners in the engine diapers flame resistant?

 

I might be able to add on to mine, then. It doesn't say anything about having to go to the top of the upper frame rail like the FC spec. Mine is about 2" below the upper frame rail.

 

Just saw on Simpson's website that the SFI-15 Shoe is now available. Will they be mandatory for next year or even this season since they're actually readily available now? Looks like any other shoe, $250.00....reasonable I suppose.

My brother picked up a pair a couple months back from Simpson, I think they started selling them at the Vegas national event. To me, looks like the difference between a "cheaper" /5 shoe and an expensive /15 shoe is a cover over top the laces.

 

the actual difference between a sfi-5 and an sfi-15 is the hieght between the bottom of the heel to the top of the shoe or boot. They may have added other visible changes. But as far as sfi is concerned that was the deciding difference between all brands sfi-5 shoe being able to be rated sfi-15. food for thought....
