    OH No Luck in Ohio

    I have many antique cars insured with Hagerty, but they would not insure my truck if parked outside... They also have a stipulation that he vehicle is to only be used for club functions, parades etc. This concerned me as I just want to ride around sometimes. I contacted my regular State Farm...

    M818 Turbo Addition

    It does not fit in the factory cradle... I removed that. I used a 5" tube with a 9" dia x 10" length https://www.raneystruckparts.com/dynaflex-under-truck-exhaust-muffler/

    M939A1 NHC Turbo

    If you up the boost & relocate it in front of the radiator it will help. There it is likely heating the air from the engine/radiator heat.

    M939A1 NHC Turbo

    The boost curve is pretty lazy & will not make much boost until the revs are up in the 1800 range, below that it falls off fast. 1100 is not bad for an exhaust temp, but I could not make any heat with the turbo before I increased the fuel... under 800 was it. The intercooler you have will be...

    M939A1 NHC Turbo

    Sounds like the turbo is not spooling. You obviously have no exhaust restriction, but the inlet air is in question. I test drove mine with a K&N cone filter on the turbo & it worked OK before I got the factory canister piping built.

    M939A1 NHC Turbo

    You said the temps go high... but never quantified that. What reading are you seeing? Also, mine would not make over 3-4psi boost with stock fueling. It is up to 12psi now with 200psi rail pressure & still only emits a light trail of smoke.

    3 Jake heads under a stock M809 hood!!!

    My center one sounded more muffled similar to the pop from an air compressor, whereas the rear one had the more obnoxioius typical Jake brake sound.

    3 Jake heads under a stock M809 hood!!!

    If you have the opportunity to road test each Jake individually, could you confirm each sounds the same? My center jake is quieter & I cannot figure out why. I thought it may be due to the firing order or the proximity to the turbo... I'm just guessing but wouldn't mind a second opinion.

    3 Jake heads under a stock M809 hood!!!

    Awesome work. I was planning the same thing, but never got around to test fitting everything. Other projects took precedence & the truck got ignored again. Thanks for sharing the measurements, you saved me a few hours of experimentation.

    M818 Turbo Addition

    That would be nice if you can share the dimensions. I put the filter housing on the pass fender, but I should build a brace for it.

    Handling heavy tires

    If you don't have a dollie... An easy way to install/remove (even on dirt/gravel) is to get 2 half sheets of plywood (preferably leave the top sheet smaller, maybe 1/4 sheet) & put 2 layers of plastic between them with a coating of oil (I used motor oil, but the heavier weight the better)...

    Sorry... I forgot to get back to you. Mine measure 2-1/4" tall.

    what cordless tool are you using to get your lug nuts off

    Funny you mentioned Wheaties when you are talking about removing nuts... lol.

    what cordless tool are you using to get your lug nuts off

    I also found out when you let the lift down on one, a replacement housing is about $35... it still worked, but was hard to hold on to.

    what cordless tool are you using to get your lug nuts off

    Milwaukee M18 Fuel with 5.0 Battery. Takes the lugs off of my 5 ton with no problems.

    Air Filter CFM requirements for 3116 and 3126

    Nice chart... You can also calculate air flow requirements for 4 stroke engines as follows: RPM X CID / 3456 = normally aspirated air flow at 100% volumetric efficiency. With forced induction, multiply the value above by (boost PSI+14.7)/14.7 to get max airflow under boost. Engines can often...

    M818 5 speed Transmision question

    I can say after adding a turbo, the gear drops are still pretty bad. The RPM drops off significantly & the turbo loses boost since it drops out of it's preferred RPM range. The turbo is a big improvement, but it does not make up for the lack of a nicely spaced transmission.

    NHC-250 Injector Size

    Mechanically, the timing of the injection stroke is adjusted as you show above, but when the fuel flow actually starts is based on how much fuel in in the injector, which is determined by the amount of fuel pressure filling it. I was referring to the duration of the injector pulse.... The end...

    NHC-250 Injector Size

    I took your advice & called Warren. He was looking into a few things for my setup. Hopefully I can get something safe but better performing without killing my budget. I was using the reasoning that the harder you push the fuel pressure to get more flow, you also advance your timing, which is...

    NHC-250 Injector Size

    Great info .... thanks. I was considering going to a larger injector to get some more fuel, while also allowing me to reduce the peak fuel pressure I'm running.
