  • DIY (LOW BUCK) JUNKYARD SUPERCHARGER INSTALL & TEST. Grab the Easy to Find, Cheap Eaton M90 superchargers from GM 3800 V6 applications. Using custom adapter plate, we installed on 4.8L LS. Is the V6 M90 Eaton blower big enough for the LS V8? Check out the results and how we made the combo really sing!!

    At 2:30, you can see the boost bypass valve is not fully closed, which is causing a large amount of boost to bleed off. The boost bypass valve is also not properly referenced, leave the lower vacuum line disconnected for this test. You can tell it is referenced incorrectly because when you let off the throttle, the flapper arm does not open. For the purpose of just running the engine on the dyno and not in a car, re-make the plate so that it does not have a passage for the bypass valve which will eliminate the variance in boost. Alternatively, you can also make sure the bypass valve is properly adjusted so that the arm is putting pressure on the set screw. You want the butterfly valve to be parallel with the supercharger. There's more to it than this, but for the sake of a short comment and just running an engine at WOT on a dyno, this will suffice.

      @gallupcustomknives2293 Před 4 lety +11

      I’d be happy to make him a custom pulley, I doubt the aftermarket ones available for the 3800 series are small enough for this application, but he will likely need to really tweak the routing to get maximum pulley wrap if going smaller. Makes me wonder why nobody runs a separate pulley and belt just for the blower, and run a cog belt like they used to, serpentine driven blowers making big boost are always fighting with slip... a cogged (toothed) belt solves the slippage.

      the pulley is actually large lol, dropping several pulley sizes would definitely help along with a different crank pulley

    • @gallupcustomknives2293
      @gallupcustomknives2293 Před 4 lety

      Jacob Burskey I doubt the aftermarket pulley options for the 3800 go small enough to make the kinda boost you need to feed an engine that flows twice as much as a 3800 but I’ve been wrong before. I know the 3800 guys still have trouble with belt slip when they up the power.

      Something is likely wrong since these m90s make max boost by 2000 engine RPM and the starting power is below even the stock 3.8's 240. I don't think the displacement is what matters as much as the CFM. Go back to 2000 when GM was making these and the n/a 3.8s had higher power output than ford's 4.6 modular since the heads flow more.

    Definitely go for the twin M90's. I had a friend when I worked at Eaton that put twin M90's on his Ford drag car in the late 1990's. It was a wild-looking thing. A single M90 on a 4.8L engine just can't supply enough air. You basically summed it up when you said the M90 was good for about 300 HP. The situation in this test would have been improved if you had just taken the belt off; then it would have made close to the NA power, with the supercharger windmilling in the breeze.
    If you can get two M90 5th-Gen's with the coated rotors, that would be even better. The coated rotors improved efficiency that added 20 HP to the supercharged 3800. I tested M112's and M122's at Eaton a lot. M122's weren't much of a step up from M112's because the intake port was no larger. The TVS series was a HUGE jump in performance because of the large intake port and improved port timings.

    So glad I watched till the end. I wanted to recommend the compound set up of a large turbo blowing into the m90, but I see you already thought of that. There used to be a Hellion kit for the Terminator Mustangs that added twins that blow into the stock SC. Sucks that the m90 is too small for this. I still think it would do good on a 4.3 in a rock buggy. Keep up the awesome work Richard!!!

      And the people who would be interested in making one of these blowers work would most likely be able to fab up a lower intake and or do like B&M back in the day and make a plate to bolt to a 4150 flange then to a blower bottom plate.

Any indication of this due to the orientation of the fitment even if you used a larger blower?

      @madmod Před 4 lety +2

      The only reason it is seeming too small is due to the 3.8 inch pulley. The 3rd gen m90 blower reaches 90% volumetric efficiency at about 12k~rpm blower speed. Assuming his stock crank pulley is similar to that of a 3800(about 7.5 inches) he's under a 2:1 pulley ratio. That means the blower didn't even reach peak case efficiency until nearly 6000 engine rpm. The benefit to a small roots blower is its ability to turn more Rpm. Take into account that this same blower has put a 3700lb fwd car into the 10s. I think if it were to drop pulleys down to a 2.8, he could get enough volume of air to pass 400 crank hp with no issues. These have supported 400 whp in fwd auto combos aswell and he could throw an ati super damper and pick up even more blower speed. Also this combo could retain an alternator with zzps 100$ belt wrap kit that would keep tension for the blower and alternator both.

      @@richardholdener1727Just a guess here - With the motor pulling more air than the blower can supply (as the dyno runs showed) the plenum goes into a vacuum state and pulls oil past the seals of the M90. Now the 4 oily runners could be that the oil is heavier than air and doesn't want to do a 90 degree turn to the rear runners. Or is it so choked down that the air is just following the path of least resistance from the M90 outlet to the front half of the plenum. Maybe have a look at the plugs and see if anything was leaned out. Keep up the great work.
