    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 3 měsíci

      Yea. I built a side view model of a suspension. I put a piece of oversized paper behind it and could draw and chart the positions. It really shows you what is going on with the rear shocks. Drop your birdcage at half inch increments and see what goes on with the shock. Then start altering arm lengths and angles and watch how it affects the shock.

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 3 měsíci

      You can also start looking at shock speed per position. The closer the shock mount ending points are to each other, the slower the shock speed is at that position. With a little work, and a simple shock dyno, you might start getting a sense on where and how much bleed you want in the shock.

    • @HoganTechnologiesLLC

    What about changing the lengths on the cantilever to multiply the spring rate? Years ago we used rat tail micro switch to limit the 5th coil to no more than 3". We ended up running a stiff spring on the 5th coil. We had a ton of forward bite even with 4 bar set up. There are a bunch of variables that constantly cause change in the 5th coil rate.... Nobody fools with it.

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      Yea, he used to build his own spindles. They were monoball style; super simple and super strong. He used to get his Rocket built to his spec and he wasn’t afraid to modify them him. His method to setting up a car was quite a bit different too. Much of it I still use today. That’s why I don’t talk much about wheel loads and smash numbers. This is useful information, but I think a lot like to talk about it without really understanding it.

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      I think most people bump their car as close to zero a possible. I think I would recommend the ackerman the same direction as a dirt car, just a little less; maybe ¼" when turning left and zero when going right. I think because of the traction on asphalt, you might take the radius of the turn into more consideration. The larger the radius, the less left turn ackerman.

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      I would assume it would be close to the same but not as extreme. Bumpsteer on asphalt I always heard was as close to zero as you can get it. Ackerman might want to get closer to the running radius of the corner to eliminate scrub.

    Drivers almost have to treat corner entry like drafting. Angleing their entry to keep the car out of dirty turbulent air left from the cars infront of them. The rise in sliders in my opinion is because quite frankly these cars today cant be over driven. And these new kids don't know that hesitant feeling of a car not turning.

      I when I first came into late model racing,stuff did go on, but there seemed to be a lot more respect. No one wanted to tear up cars like they do now. I don’t know where this slide job culture is going, but it interesting to keep an eye on. Thanks for watching.

    Like spring rate, I have a hunch the frequency will halve too when 2 are stacked. I have no data on this, just a hunch.

      Frequency decreases as spring are added in series.

    • @BobMarley-bm8hw

      The gentlemen above are correct. When calculating the oscillation frequency of two springs in series, the effective rate is used. So a single 200lb/in spring will have the same frequency as two 400lb/in springs in series with an effective rate of 200lb/in.

    I'm curious as to what speed aero take effect, or at least is a contributing factor. I drive a hobby stock. 99 Monte with a late Camaro nose. I feel there is an advantage, but at what speed?!

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      I think there is always some effect. The faster you go, the more of an effect.

    Great video, I am not from the USA, and I am not familiar with the dirt late model rules, but is there any rules that forbid paneling in the underside of the car and running a diffuser?

  • @RickJ.Dalton
    @RickJ.Dalton Před 5 měsíci

    The large left wheel wells i think would cause more air to be drawn through causing more drag like they say with driving a pickup with the the tailgate DOWN actually makes gas mileage worse.

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      I agree with making the right side wheel wells small to not let the air I, but I think getting as much air out as possible is a benefit. Years ago Josh Richard’s showed up at Screvin, I think was, with ½ the LR quarter panel missing. He was clearly faster. They made him correct it and the car slowed down. I think there is something to getting as much air out as possible.

  • @richardhatfieldgreg3851
    @richardhatfieldgreg3851 Před 5 měsíci

    Great video. Totally agree with the left rear needing a bigger opening for air to escape. What about RR dynamic height being so low? Doesn't that contribute to the LF problem?

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 5 měsíci

      Yes, definitely. The RR height does affect a ton. I do go through what I think needs to happen in another one of my videos. Thanks for watching.

    The part youre missing is if there isnt air on the nose entering the corner everything's youre saying is irrelevant! PERIOD!

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 6 měsíci

      We will always have some air on the nose. What I’m saying is that instead of being 90 percent dependent on air, we should get the cars to steer better naturally and be 60 percent dependent on air.

  • @chazbuchinsky19
    @chazbuchinsky19 Před 6 měsíci

    See what you just said is why I won’t run anything but a stack LR. You can’t control the left rears ride height correctly and have a good drop out load with a single anymore. It’s to big to a range. If not like you said your LR ride height and RH load will be trash also. I like to run less drop out load then most because it keeps your car free

    What is RTJ doing to get the nose to float in air like a Cadillac. His car seems to articulate and float over the ruts.

    • @KevinKatzenberg
      @KevinKatzenberg Před 6 měsíci

      He is good. I don’t know if I could contribute it to just one thing. Things like that seem to be a good combination of shock valving, spring choices, and even driving (how to hit the holes). It seems he is still a bit on the tight aero side. He’s really just a talented driver. Thanks for watching.

    1. Why not just raise the RR up and teeter back to the LF with your LR/RF as a pivot axis? In my experience, when we get too far with this the car doesn’t stick the right rear and skates. Some call this no “side bite”. Whatever that means haha. 2. When the LF comes off the ground it becomes sprung weight and now the other 3 tires are carrying the weight of the car entirely. Specifically loading the LR/RF. 3. I agree the aerodynamics are about rake of the whole car. It’s also about unshrouding the spoiler from the roof. I also agree the LF should be on the ground. Where I’ve landed at the moment is that it’s all about loading of the LR. The chain attempts to jerk the LR off the ground until the forces balance out. Toting the LF inherently loads the LR, somewhat negating the upward pull of the chain. I think this is specifically what Rumley solved with his trickery (along with controlling rear steer with respect to axle wrap) but all that stuff is outlawed now. Thoughts?

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 6 měsíci

      I've gone back and forth for years with the thoughts about pulling that LF off the ground. Right now, with cars that are way too tight, I'm leaning toward keeping the LF on the ground. We could raise the RR. And, that would solve the problem of the RR not being loaded and help put the connection back in the LF. I think the problem with the chain snapping the LR off the ground is a severe problem. This can be partially solved by adding more extended load to the LR spring. So at least the LR would be riding on the spring. Thanks for watching.

      @@HoganTechnologiesLLCthat’s where the stack LR is the better option if you know what to do with it. Less drop out load but more RH Load to keep it there is better for me atleast

    Tire Temps will dictate your camber * ADave Hammond is the king of setting up your chassis when it’s in its Dynamic phase..

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 6 měsíci

      Tire temps are a useful tool, but I find the problem with tire temps, on dirt, is it is hard to get enough temperature in the front tires to tell a whole bunch. Plus, as soon as you come off of speed, they begin to neutralize. Tire wear over time is about as far as I go.

    A lot of your information is great for the late model guys but I'm a modified guy so no stacking springs for me so a lot of this I don't think does me any good ? So it would I would be changing rebound and compression on a shock with not stacking springs ?

    • @HoganTechnologiesLLC
      @HoganTechnologiesLLC Před 6 měsíci

      Thanks for watching. A lot of mod guys are changing shocks to adjust to the changing track conditions. Just changing to a shock will affect your car a ton. As the track slows down, you will get less weight transfer to the right. Opening up the bleed area on the right side shocks will speed up the weight transfer as the track conditions slow the transfer down.
