Truck caught on fire last night at pulls

Inregards to the turbo, I believe when adding the twins you can get a thicker plate for the wastegate. The thin plate they put on from BD can't stand up the the pressure. I don't think its a gasket, just a silicone bead ran around it

I ordered a replacement from Gillet diesel today since BD never called me back, but If this is going to be a re-occuring issue I would rather just get the thicker plate now:thumb:On another note I believe my waterpump failed leading/contributing to some very hot under the hood temps
Hopefully nothing internally got to hot...
Thanks for the info:thumb: It appears the plate is machined to fit without a gasket or sealer from what I am told
But I was also told some people use Red RTV to help seal it.

Yes, get a thicker side plate from ED or whoever and check for flatness on the exhaust housing and the new plate. It will surprise you that things are not always flat out of the box. Then reassemble with thin layer of red rtv.
I just looked at my HTT and it has a thin plate with some red rtv on it.
Is ED the only ones that sell the thicker plate, or can I get one from HTT?

I talked to a local machine shop who said they could make me one. I would think most any (Well Equiped) Shop can & will make you one.. But on the other hand if Ed has them sitting there ready to ship that might be a better route to take?

I would check stuff over good something isnt right IMOP it takes aloooot of heat and drive pressure to kill those up pipes so quick , the big power trucks can have them fail but not after only 2 runs , I would guess the up-pipes let go first then , started the fire when they pushed into the fire wall , is your waste gate tuned right ?. And def check into the water pump .

I am leaning towards waterpump but have not had time to pull it yet. As far as the wastegate I have no idea if its set right or not. I literally had 7-10 miles on the set up before I ran it down at E-town. I do not have a drive pressure gauge yet and my second Boost gauge is sitting in my back seat. I know my 100lb boost gauge was reading around 60lbs on the street and EGT's were good. I figured nothing was being hurt since the EGT's were still in check
I know right after the truck caught on fire at the pull,, I put it out and the engine temp gauge was buried in the hot zone The truck ran cool down to E-town the weekend before with engine temps never going over 210-220 or so and that was after running 3 all out runs with a 3" hole in my boost tube And before anyone says it, YES I know I'm dumb not fine tuning my truck before beating the sh!t out of it.. Oh yeah, another thing worth mentioning, when my truck caught fire I never shut it down, I put out the fire, looked at the engine temp gauge, and idled it off the track, after sitting idling for 5 - 10 minutes the engine temps went back down normal. My question is, if the water pump was infact the original root of my problem would the truck still be able to bring the engine temps back down to normal readings in a matter of minutes??
Another thing interesting, is although my up pipes were ballooned, expanded and pretty much FUBARD they did not leak!! I pressure tested them and to my amazement they held pressure. Not sure what the bellows are made out of but its some pretty strong stuff...
when mt pump was gone it would heat up driving even easy , but would come back down fast just idling
Well theory 1 is out the window...
I decided to pull the water pump today before going any further, Much to my surprise everything is fine:thumb: The Gear side of my pump is Tig welded but the impeller side is OEM, Should I weld the impeller side aswell since its out and apart already? I am glad I pulled it even if it was just for peace of mind Oh , and I already bought a new pump, lol So I guess at this point I am going to go with Trents theory on BAD drive pressure being a factor in overheating things to the point of catching on fire??? As far as the Wastegate Plate on the BD I just doubled the 2 plates up and used a slightly longer bolt, hopefully that will be enough to keep it from warping/expanding again.. Feel free to throw out some suggestions fella's :hug: Trial and error gets expensive fast :beer

I would not weld the gear. The impeller is pot metal and will not hold a weld. It will end up expanding from the heat of welding and when the weld breaks the impeller will spin on the shaft. Been there, got the t-shirt.
