    How to set the timing on your 6.9 or 7.3 IDI and how to buy timing equipment.

    -20 degrees is 20 degrees AFTER top dead center.

    How to set the timing on your 6.9 or 7.3 IDI and how to buy timing equipment.

    I got the last part of the timing package for these engines today. The timing light. And I have a large hard case to store it all in. I have an excellent wife! Besides. She wants to see this truck run again AND wants a ride.

    Supercapacitor/Ultracapacitor starting bank

    The studded caps would be a better option in my opinion. 1/8" thickness is too thick to spot weld. And I'm not too sure that aluminum would spot weld properly even if the connecting strap is thin enough.

    Supercapacitor/Ultracapacitor starting bank

    They cant be spot welded with a spot welder that is designed to spot weld battery packs together? I have a spot welder that is designed for things like this.

    Air to Water Intercooler

    Thank you asmith! I cheaped out and bought the 2 1/2" intake hat. Mainly because it can be rotated and that may help with alignment. And of course I have several hundred bucks in parts to be used to put this puzzle together. Also have a 90cc Moose pump that Wes sold me. I can't wait to drive...

    True. Graphite conducts electricity. So in theory drawing that line can cause all kinds of hell to break loose. And very not likely that the engine will run. At least not well enough to get home.

    Air to Water Intercooler

    I have a serious urge to mount the radiator for the intercooler under the truck. I think it's doable and can be adequately protected. If this can be done it will get that extra heat somewhere other than in front of the radiator for the engine. And simplify some things. It would be mounted at an...

    Air to Water Intercooler

    Wes@ Classic Diesel Designs sells a 2 1/2" intake hat. Just bought one. This should flow better than the snail intake hat and likely make the connection to the intercooler easier.

    Air to Water Intercooler

    Update. Air to liquid intercooler kit from Frozenboost will be here tomorrow Monday 4-12. Waiting on injectors from Wes @ Classic Diesel Designs. But I have brake parts here for the rear that need to be taken care of before I can move the truck from one side of the house to the other. One of the...

    Air to Water Intercooler

    Given the short pipe runs I think I am going to go with a 3 inch intercooler and piping. May check with a local machine shop about welding a 3 inch stub on the intake manifold. It's possible that the charge to do that won't break the bank.

    Air to Water Intercooler

    The reason I am questioning a 3" inlet and outlet intercooler. I'm not going drag racing so turbo lag may be a non-issue. It would go from 2.25" to 3.0" and back to 2.25". So maybe little lag. This is partially what Asmith has done. With the exception that he has a 3" inlet on the intake...

    Air to Water Intercooler

    I see in Asmiths post that he went with a 3 inch intercooler. 2 1/4 out of the turbo into a 3 inch intercooler. And of course the modified intake manifold with a 3 inch inlet. I'm wondering if this induces turbo lag. Or if the lag if present is insignificant. Knowing the nswer to this will...

    Air to Water Intercooler

    Does anyone have any experience with Frozenboost.com? Specifically their kits. I want to use an air to liquid intercooler. They have several kits and all come with pump and radiator to be mounted in front of the cooling stack that we already have. A plus is that the radiator and the pump are a...

    Re-Torquing Head Bolts

    I did a bit of searching. Still need to do more. The air temp out of a turbo can be in excess of 300 - 400 degrees depending on how much compression is happening. I think I am going to try the engine cooling system as the first test. And go from there. Maybe use a temp sender for charge air temp...

    Re-Torquing Head Bolts

    I was absolutely blown away when I got up that morning and checked the weather station (my private weather station that I actually broadcast to Weatherunderground) and saw the low temp. It's never ever been that cold here. Oh yes. I have been reading and following the forum for some time now...

    Re-Torquing Head Bolts

    I have not replaced the thermostat. I probably should though. I have no idea if it has ever ben replaced. Something I will look into. I am Some miles SW of the DFW metroplex in Texas. Speaking of cold. When your weather got drunk and wandered down here I saw MINUS 11 degrees the first morning...

    Re-Torquing Head Bolts

    Correct. And I think that a bypass through a smallish radiator and then on to the intercooler may work well. By the time the water (coolant) comes put of the intercooler it should be close to the same temp as the coolant circulating through the engine. I think it will work and I had not thought...

    Re-Torquing Head Bolts

    What you propose makes a lot of sense. Looking back in time, technically the Cummins engines that I worked on were aftercooled. Engine coolant was used to cool that aftercooler. And there was no separate coolant cooling system for it. After thinking on it for several hours I think that after the...

    Re-Torquing Head Bolts

    Here is the reason for asking the further question about air to water intercoolers. Many moons ago I worked for a truck leasing company. All Cummins engines. They had air to water intercoolers that were plumbed into the cold side of the engine coolant system. I am assuming that the radiator in...

    Re-Torquing Head Bolts

    I DO appreciate all of the advice given. Thank all of you. Like I said. This is OJT for me. And thankfully I learn fast. In this case many of you have gone before me and I'll take experience over a book any day of the week. At this point all parts bought other than the turbo kit (ignorant at the...
