Great outcome Grant!
Thank you!
Glad to see you were able to get this posted. The black box of the tranny is finally gone with the TC change, just got to get the temps where they need to be. Great video!!
Thank you Ted, yeah if I can get the cooling figured out I'll be golden for sure.
Glad to see this new video! About 15 minutes before the video dropped, I had checked your channel to see if maybe I missed an upload. Then BOOM! There it was. Happy to have you back! Great info as always.
Thank you so much! Yeah my life got unexpectedly busy right after New Years and I just haven't been able to do as much with this channel and Jeep as I use too. I've already filmed the next video but I'm working on editing it now, so that one will hopefully be out sometime in May.
@@RustyAutoholicGuy Cool! Can't wait to see it. Thank you for making good, fun content.
Your EGT is much higher than 650F. My CJ is 700-900F with the Holset and the XJ is a little more with the GTD and the AW4. This is with the CJ in 4th on the AX15 @ 55 and the XJ in 3rd @ 55.
If you're having cooling issues with the speeds you're running in the video, hook up a coolant pressure gauge and let me know what you're seeing. Now that I replaced the headgasket in the CJ, I don't get higher than 204 to 206F. XJ is about the same.
Awesome video! This has definitely fueled my idea on wanting to tdi swap my Ford Ranger. I have been kicking around the idea just to have better torque and fuel mileage. Would you know roughly what stall rate the stock converter was? Im trying to keep as much of the original drivetrain as possible, and there is a kit by tdi conversion that will allow me to bolt right to my 5r55e transmission. Im sure my stock converter stall rate might be too high. Any comments are much appreciated.
sooo... what do you think the difference might be on the two torque converters (maybe measured as Stall Speed and Lock-up).
stall speed or even at this point I have to wonder if it was somehow damaged when I received from shipping years ago. Without sending it off to get someone to cut it open I'm not sure I'll ever know. At this point it's not worth the time or money to have it looked at.
The this that still really gets me is how much quieter it is, both unlocked and in Lockup which makes me this the other converter was defective somehow.
Some cooling help, maybe. Comparing my '83 Toyota FJ60 LC with Cummins 3.9 4BT to my '07 Jeep Wrangler JKU also with the 4BT, the JKU tends to run much hotter. Why? The Jeep has a much tighter engine compartment with a water to air intercooler radiator out front, a mostly in-the-bumper winch and a bull bar with a light bar. The Toyota, with a huge engine compartment, no intercooler, no light bar on the bull bar doesn't need the electric fan connected. Yes, it runs cool with NO fan at all. Tried the no fan mode with my Jeep and rapidly overheated climbing into town on the highway (65 mph). Apparently, the Jeep body design doesn't flow the air that the Toyota can. Is it possible that the tanks on your intercooler and the CFM of your fan are failing to flow enough air to maintain normal temps? Could too much air be bypassing your radiator due to missing factory plastic inserts? An old engine swapping book said you can have a 6 foot by 4 foot radiator and still overheat if you don't have enough airflow. Yes, it will take a long time to overheat, but then you have a large volume of hot coolant.
RustyA...
Could you please show the fan shrouding behind the radiator?
You need a tight shroud to make the fan suck air when the fan is working hard at low speed......
but the shroud can have large cut outs with top hinged rubber flaps on the rear of them that automatically open up under forward speed thus allowing much more air to flow through the radiator at cruise when the electric/mechanical fan isn't needed or isn't effective...and a tight shroud just blocks airflow.....
At speed the rubber flaps open up from the inrush of air through the radiator which can double the amount of air ;passing through the radiator core....
When speed drops the rubber flaps close up making the fan effective in drawing the maximum air through the radiator.....
Also seal off the radiator edges all around so air cannot freely flow into the engine compartment...
any air must be forced through the radiator...
You could also have a separate air intake for the engine combustion air....this being taken from in front of the radiators....the colder the better for a diesel.
