Car built to SFI 25.2A Chassis Specification (PIC HEAVY)

That's much more convenient than have to go to Cali to pick it up in a port. Will y'all be keeping it at y'all's place until finals?
 
I have a lot of running around to do with the truck to finalize things before the track opens 6 days later I'll just be keeping it in a trailer with me while I'm in Dallas.

The team arrives on the 25th.
 
Sorry, I was out of pocket traveling for a while with intermittent internet access. The items I would have mentioned seem to have been taken care of in the final photos (no 6C and 41C too far back). Can't wait to see it in Ennis! The rulebook will have all the safety gear requirements. Since it is a turbocharged vehicle, if it has an aluminum firewall then the driver will need an SFI 3.2A/15 firesuit. If they're willing to let someone else drive it, I'll be there driving in Sportsman ET, and as the reigning Pro Stock champion I automatically qualify to race in the event!

This would be quite awesome. Please let us know if they'll do this and if you would fit in the truck legally. We are sorta if'y about coming for sure. This would seal the deal.
 
I bit off the original topic:

I've been pouring over the 2013 NHRA Rulebook to find the guidelines for the rest of the safety equipment for these guys but am getting a little lost as to what set of rules I need to be looking in.

If any of yall can assist me please call or text nine five six 434-90six five

I appreciate it!

Here are some pictures of their gear and a diagram they sent me for layout within the chassis. Please advise on the location of certain items such as fuel cell, Nitrous, and battery shut off.

I have a feeling some of these things in the diagram will need to be moved.

If anyone can tell me the section of the rulebook that would apply to this vehicle I would greatly appreciate it.

319 pages of regulations is a lot of digest LOL

I've been keeping up with the build to and it looks great. I can't wait to see it in texas.I've been wondering what kind of tranny is in it it's always covered up.:lolly: Me and ashley have worked some very long hours on our truck but got to hand it to them for getting that pulled together much less plan to bring it over seas from that distance.
 
I an glad fuel is in back..
Water would be ok inside, but not fuel, without a firewall etc.
Nitrous is ok inside, needs bottle vent through the floor.

and he is a very cool dude too! not everyone will let a 5 yr old drive thier pro stock truck!
 
OK I sent this image back to the team after discussing a few things with a few other racers.

Looks good with the revisions. One more thing I just realized, I didn't see any mounts for a window net, but I saw arm restraints in a photo. Many years ago arm restraints were allowed in lieu of a window net, but not any more. It will need a window net attached inside the cage structure.

For the helmet they should get a photo of the SNELL or SFI tag on the inside under the padding.

One thing I am a little concerned about is their fix for the 16B door x-bar intersection with the #11 dash bar. It looks plenty strong but it will be up to the judgement of the chassis inspector. If you haven't already done it I would be forwarding him these photos as well.

A couple other general items:
SFI flywheel and bellhousing.
SFI balancer/damper

They are working on the window net.

I have sent Mark (the inspector) a bunch of pictures from during the build and will update him with the final build pictures.

I will let them know about the SFI flywheel, Bellhousing, and balancer/damper
 
Here are some relevant sections from the NHRA rulebook:

Please note that the clutch itself also has to be SFI (assuming this uses a conventional clutch rather than some form of torque converter drive).
