4000 HP Cummins on the Dyno

[@optimalxrecovery3308]

That close in to dollar shave club ad was BRILLIANT!

[@bcbloc02]

Just a tip, if you want to avoid problems with the crank bolts next you need a thicker flexplate. I welded a double center in the puller because the thin flex plate wanted to knife shear the crank bolts once we went to 12bolt and quit breaking them. Those diamond impregnated washers are important too. I would have borrowed a mig welder and welded the TC to the flex plate thru the holes just to get it to pull off the dyno and get the win.

[@madmodifier]

@ PowerDrivenDiesel FYI this gentleman is a machinist and does work on diesel pulling tractors. Might be a good person to take advice from imho.

[@consaka1]

I'd be happy to find a 12v that just put out 600hp for my Tow rig. Probably be a bit more of a reliable workhorse than the worn-out 6.5 that's in there now.

[@chrishansen7004]

[@levi5.9]

I wonder if there is a way to dowel half the holes on a twelve bolt converter to make install faster by also lining it up going in?

[@ryanburbridge]

Levi Marquez there is absolutely a way to do that. But...

[@levi5.9]

@@ryanburbridge I just wonder if it would be cost effective

[@ryanburbridge]

Levi Marquez it would definitely add some strength in shear but from the sound of it they have the torque converters they like and that’s that. But i agree... 6 bolts for clamping and six dowels for shear sounds cool.

[@levi5.9]

@@ryanburbridge sounds pretty quick for install the dowels would be just like a lineup tool

[@TreYay83]

Just run 6 in the 12 bolt. That way you can still push it, still sheer the bolts. But have 6 more holes to re bolt it back together and get it off the dyno!

Grade 8 hardware is for stock vehicles and this isn't the first time I've seen them fail on flywheels/flex plates.

[@glennhobbs59]

I’d try to make some custom head studs into tq converter bolts

[@MaxCaissie]

Idk if that would would since head studs are meant to take tensile force and not sheering force

[@glennhobbs59]

Max ya it was just a thought need something stronger that can take a side load and hold the forces against the hardware

[@thomaskiger6960]

Need to safety wire them

[@matrixssc2]

Probably the best way to prevent bolts from shearing off -> bigger bolts or a custom flex plate and converter that are keyed together

[@chloehennessey6813]

matrixssc2 I’d be up for machining a custom flex plate for them out of Inconel or titanium. I’d do like you said and machine in some key ways and use titanium for the keys as well.

[@matrixssc2]

@@chloehennessey6813 ideally the flex plate and keys would be one piece. Think splines on the outside of the torque converter and inside the flexplate .. Also, those metal are excessive as most SFI flexplates are steel

[@chloehennessey6813]

matrixssc2 Thanks didn’t know that. I’m just basing what id machine off what metals we have here and what we normally machine for the aerospace industry. I just figured if the metals are good enough for say RocketDyne they should be okay in a truck?

[@brentallen4512]

Could you machine the torque converter cover to accept 3/4" bolt and mill larger holes in the billet flex plate? More surface area for loctite and stronger bolts. Win win.

[@wrfarms9741]

Have you considered using an aviation type safety wire & grade 8 drilled bolts or better yet some aviation type titanium drilled for safety wire bolts to prevent the converter bolts from backing out? You might have to have your converters made with a fine thread to use bolts like these. If you can break 12 of these, you have some serious engineering challenges ahead.

[@M977A2]

Nickel based alloys would be better, titanium is great for strength to weight ratio but not ultimate strength. Inconel alloy might be a better choice, the high temperature properties are not needed but the strength is amazing.

[@Ariccio123]

I think papadakis racing sells nice jigs for drilling holes in bolts to make your own safety wire holes

[@adamtheede2575]

could the smoke in the air effect density? and rob power

[@uglymechanics6599]

Theoretically yes. But the odds of it actually losing power would be negligable

[@dburkh91]

[@steveroehlk8799]

Probably the biggest part of the difference between the Superflow and Mustang numbers. The Superflow was outside and the engines aren't reburning exhaust. Huge difference. Engine dyno rooms using ambient air like an air exchange rate of 10 or more times per minute ( all the air in the cell is evacuated with fresh air 10+ times per minute).

[@1452-w3b]

I love how everyone was flabbergasted on the second run🤣🤣🤣🤣

[@powerstrokelife3119]

Some loctite tips are to clean bolts and holes with brake cleaner and then blow out with compressed air then use the loctite primer (7649) before you apply the loctite (262). If you have a blind hole put some in the hole and on the bolt otherwise what is on the bolt will actually get forced up the threads as you screw the bolt into the hole and push the air from the hole. Also have to remember heat will breakdown the loctite. I have sat through loctite training classes and learned a ton about what we had been doing wrong. If the bolt comes out without crusty loctite on it you didnt do something right is a good rule to go by. Hope some of that might help.

While I can see that it would be a gigantic PITA to have 12 converter bolts I don't see where you all have many other options if you want to guarantee that this won't continue to be an issue.

[@Parents_of_Twins]

@@pddofficial I haven't dealt with that type of torque converter so I'm trying to figure out how you all used different bolts, every converter I've dealt with the studs are attached to the converter. Doesn't seem to be worth the risk to not run 8 or 10 bolts at least, that being said I'm not a gambler. I have a tendency to overbuild stuff, especially if my first iteration breaks. I'm pulling for you guys and still waiting for you all to start making 68RFE parts. I know if I buy it from you all it will be thoroughly tested so I don't mind waiting.

[@jacobmoses3712]

Did you ever find a solution to the bolts breaking problem?

[@paultavres9830]

Basic thing to do is shut it down let it cool add water pinch the cote tubes leaking leave the radiator cap loose so the radiator doesnt build pressure Why not run 6 bolts and 6 studs If you have to pull it remove the bolts and slide the converters over the studs Maybe they will help spread the torque You guys are truly gear heads

To take them off after they wore out I had to heat them up real hot with the torch and use a high quality 3/4" impact gun to take them off. Get some of this and you won't regret it.

Hey boys - I understand you love the 6 for ease of pulling the trans... But why not use the 12 but only with 6 bolts? Put screw in pins in the other 6 holes -- this takes a little stress off the 6 bolts, and it lets you pull the pins and install the other 6 blots if you want...

[@daviddroescher]

It would work. One problem with 1" bolts you need 1" of thread engagement for full strength. Could solve with a spacer between the engine and transmission to make up the extra space needed. Adding "dogs" to the flex plate would transfer the shear load to the dog/bolt pedestal interface, and the bolts then only experience thrust loading. Set the dog/ pedestal like this // so that the flexplate will suck the TQC up tight if a bolt ever backs out agen.
