I will soon be plumbing the Spyder. The simplest route for the various runs of tubing is straight down the top corners of the large transmission tunnel. Running it down the inside of the frame rails will put everything in very close proximity to the mufflers and definitely require heat shielding. Running it down the outside of the frame rails is pretty much a no-no too.

I'm pretty sure that NHRA won't allow any plumbing in the driveshaft area no matter how well you armor it. If they won't, I doubt any other racing organizations will either. Am I correct on this? I may never have to pass NHRA tech, but I figure their recommendations have good foundations.

I do plan at least 1 driveshaft hoop (most likely 2) and could fab a protective shield that is virtually bullet proof (literally). I may also look into extra steel around the bellhousing area since my feet will be right next to it.

I'm not really planning on racing the car seriously, just an occasional "run what you brung" drag race or auto-X.

Any thoughts on this?
