    The hole that you cut in the diverter is part of the precleaner. It is supposed to get the air swirling and the centrifugal force cause the dirt to separate. What will happen with your setup is that you will get a hole in the filter element over time, because you will sand blast it with dirt and moisture. Also, the fording hummer bypasses the drop box by adding a rubber elbow inside. Your hummer is not made for fording.

      Great points you make yes I seen the elbow fording kit for sale My air intake is basically hood height ( no I do not ford water with it I use it on a cattle ranch and I try to stay out of the mud as much as possible) should I extend that up higher or does it not make any difference? not sure if a 4" rubber hose would be the right fit I seen some of those for sale on ebay.

    So maybe you should have looked at the h1 a little bit before doing all this. In the h1 there is no deflector in the snorkel box, it has a 90deg. Silicon elbow. And they have a k&n style air filter. They did all of that so the dmax could flow the proper amount of air.

    At the end we haven't heard how much improvement it made to the engine performance- the design is to create swirling vortices to separate heavy particles which isn't as efficient as straight through flow. I also met a guy two years ago that had changed his HMMMWV's radiator to an Aluminum one saying it is the best cooled HMMWWV in the USA> then what? what is the practical gain?

  • @gfactor559
    @gfactor559 4 года назад +6

    Did I hear you correctly (if not I completely wasted a lot of time here lol).....you put in a V8 LS gas engine in there? I'll say this as nice as possible with regards to you saying that there wasn't a very noticeable power difference.....Do you understand how gas and diesel engines are different from each other and how the application of any engine is of utmost importance to understand?
    For starters, HMMWv's weigh over 5,500 lbs (depending on the variant you have). Lecture time: You need something with high torque, because torque is the actual force that gets a vehicle moving forward. Horsepower is how "fast" that work is done. This is where "application" comes in....when I was a teen till my mid 20's, I was really into trucks. At some point 2 wheel drives and other times 4x4's. My last truck was a 70 Chevy and I put a Mark-5 (I think '94) 454 big block in it with a turbo 400 transmission. Obviously I was looking to go fast, but what I soon learned was that no matter what I did, a car was going to be faster (for many reasons). Trying to make a truck go extra fast turned out to be a retarded thing to try to do. So then I got into cars and not too long later, Audi's (which I still have 1 now). My point to all of this is "are you really just trying to make your HMWWV fast"? To me, logic dictates that's a complete waste of time, energy and money.
    Back to the issue you had of not much power difference.....Well duh, of course not! You have 400HP now compared to under 200HP with the HMMWV, but what's the torque output of the LS? Secondly, the diesel engine is putting out it's max torque at like 1,500RPM and around 300ft-lbs (if it's the N/A 6.5L). Where is the LS putting out more than 300 ft-lbs and what's the RPM.....basically what's the torque and HP curves look like when put together on a graph? Gas engines normally need to be at a high RPM to get the torque and HP numbers up, and what that translates into in real life is that you gotta be hauling ass all the time to produce those big numbers. Do you really want to constantly drive your HMMWV 100mph+??? To me it seems like you're trying to break a block of cement with a regular hammer. You want to use the regular hammer because you think that swinging it super fast is going to get the job done amazingly....The reality is that for a HMMWV, you want a slow swinging 10lb sledge hammer to break that block. In a light weight Vette that LS will kick ass because the Vette weighs like 40% less or so (just my off the cuff guess). You don't need a ton of torque to get that lightweight car moving. Actually you can totally have too much torque in a car and it will completely work against you. If a Vette has 1000 ft-lbs you are going to lose control of that car and wreck it really quick unless you're The Stig. Ideally you'd want a moderate amount of torque and high HP.....that way it's far more predictable and controllable (unless you have an all wheel drive car, then you can have high HP and torque combined). In a HMMWV you want the opposite.....high torque and low HP. The way when you are off-road you have all the pulling power you'll even need, but with the low HP so you can control it in the off-road environment where speed is actually a bad thing.

    If you trimmed the snorkel tube like you plan but leave enough left to get a hose clamp around it you could get a sheet of “outerwear “ like a fine mesh pre filter designed to repel dust and water for off-road intakes. Just if you some how didn’t know. And that would probably do much the same thing that the stock plate was there for, and it should effect airflow minimally to not at all. I bet water and larger dirt particles would loose velocity and gravity would take them to the drain. In case of water and some dirt but most dirt would just get stuck on the outside of the prefilter. There like $20 off amazon or something. Will also keep your air filter better for longer saving money. Or if it’s a cleanable filter save you the hassle of picking out big bug guts and trying not to damage the filter while doing so and then actually having to do it more often. The outerwear can just be cleaned in a sink usually even without a little dish soap but I do usually use a little just because it’s always there. Heck even a water bottle poured the reverse of air flow would be just fine and hose clamp back on

    So as I was saying. If you inject more Fuel W/out More AIR it Can't Burn the Fuel. U must have the Ratio Right or like the old Trucks use to SMOKE = U see Black Smoke is Unburnt Diesel.! So as I use to grab the Next Gear Pulling 80 Thousand PDS up a hill the old Mack's Would SMOKE BLK SMOKE Until the R.P.M.s Caught Up. Then the Air Ratio would be Corrected. ! I Hope this helps Explain. Better. But No my Friend Get that Hole Fixed & get You A Turbo For That Engine... Then it will have Air Pressure in the Air intake & as the Value Opens Air= Oxigen is Forced into the Chamber & NOTICEABLE POWER COMES NEXT...

    • @Leo-zd7nv
      @Leo-zd7nv 5 лет назад

      Why argue about it?
      Surely you don’t think that every vehicle is going to weigh exactly the same? Mind you, a 2,000 lb. weight gain stretches the bounds of credulity.
      There are various modifications for different variants that will add or take away a few hundred lbs.. A vehicle may even have had a modification done at the unit level, to suit individual commanders. That could change the weight of the vehicle by a few hundred lbs.. A vehicle could gain or loose weight just from the difference between welders if the welds done by hand. Even how many times a vehicle was painted will increase it’s weight.
      It does surprise me though that people who are obviously using the internet refuse to check readily available specs before they destroy their credibility.
      Wikipedia lists the weight as: 5,200 to 5,900 lb (2,359 to 2,676 kg) curb weight, 7,700 to 8,500 lb (3,493 to 3,856 kg) gross weight

      A 6.5L engine at 3400(redline) assuming 90% efficiency needs 351 CFM. With a clean filter this should not be a significant restriction/power loss on the original engine.
      You could always do a dyno run fully stock, then put a large K&N type filter nearer the intake to test this. I'm sure that would be a popular comparison video/post.

    • @LSXHumvee

      I ended up cutting out the entire inside wall of the air intake box. It should flow plenty of air now. When I did the math on how much air flows through the intake cap it was WAY more than what's needed so hopefully the mesh doesn't restrict too much but that will be the next step if I need more air.
