stack temps
hey guys I have a ?,you guys that run stacks does the temp of the stacks get pretty high. I am going to install my new 6" mitre cuts this weekend but I also carry a 110 gal offroad diesel tank and lift pump in the front of the bed. will I be OK to leave the tank where it is or will the temps be high enough to be dangerous. thanks for any input

good idea. i would at least put some fire-retardant material between the tank and the stacks to prevent any heat from getting in. after my next drive, let me get some temps for you. i have a infared temp gun from my RC career that i will use..
however let me say that the chrome part is too hot too touch. i have some friends with burnt fingertips who put some finger prints on my stacks. it only took them once to learn, i still havent, though.

I wondered about stack temps, but mine don't seem to get too hot. I've got some plastic caps on the bedrails that my stacks are no more than 1/8" away from. I've been checking them, but they have not once shown any signs of melting. I'm pretty sure they would melt before they reached the flash point of diesel fuel, but some heat shielding can't hurt. I'll be curious to see what Kris finds with his temp gun.

I'm curious too, but let's be for real. Diesel is not that flammable with a lower flash point than other fuels. Second, If that is a metal tank with a large surface area, and plenty of fuel, I'm thinking no problem. The only issue I can see is with a lower fuel level and vapors. Even then, I've thrown lit matches into diesel fuel and they went out. This in the desert. A word of caution, this does not apply to vapors in an enclosed fuel tank though. A definite unknown there but I think it would be OK.

today after a 30 minute drive with intermittent sustained temps of 800* pre-turbo coming home (in the last 5 minutes) i pulled in the driveway and hopped up on the toolbox. EGT in the vicinity of 500* and falling.
area where the pipe splits in the bed- 275*F
left side before the 90* upward turn- 203*F
right side before the 90* upward turn- 240*F
inside the tip of both stacks- 139-145*F.
tried to take a measurement on the chrome part outside, but it just reflected the beam off and took a reading of the temp gun. it only said 85-100* so i was pretty amazed at how low it was, so i touched it, and no, it was not reading actual temp!

I don't think the diesel fuel tank should be of any concern. There's really no way it's going to ignite being a.in a metal tank, b.uncompressed, c.it just ain't gonna ignite.
Try pouring a bit of diesel on the ground and hold a match or lighter to it.
I'd be more worried about carrying something plastic in the bed and having it end up against the stacks and melting... guess that's something I'll have to address for if I ever add stacks. I've seen some guys with some diamond plate shielding over the in-bed part that looked pretty good.
