    You guys need to keep a notebook of weather conditions and jet size to help speed up your tuning at the track for subsequent visits. Also, John, it was great to see you take the C10 down the strip. No need to apologize for your shifting, you put your heart, soul and wallet into that truck.

      @@braziliansheetbox2497It takes more than just jetting to run E85 as well. Being 85% alcohol, it’s closer to methanol than gasoline. If you look on performance parts websites like Jegs or Summit, you will see that e85 carbs are different than either gas or alcohol carbs. I’ve been running E85 since they started having it at the pump in the mid 2000’s, and it’s a great fuel. Part of the problem is methanol is costing them power right now because they aren’t running enough boost or compression to need it. E85 would be a better choice, and they need to talk to some good carb shops about building a carb for them for E85.

    @stevebrueggen800 Рік тому +4

    Hey guys, once you get the engine putting out as much power as possible, THEN, I feel that you will gain a substantial amount of performance by tuning the drive clutch. Figure out where your power band is, and play with the weights and spring (in the drive clutch) to get the clutch to engage within the power band. You want to put all your hp to the ground on take off, so you have to get those rpm’s up there. Snowmobile dragsters have been doing it for years. Heavier spring/lighter weights will make a difference. But it takes a lot of trial and error. Good luck.

    What you guys are doing is fantastic. I have watched this build from its beginning. You have been working so hard trying to get your machine to get a better track time that you have overlooked one of the basics of engine building. You have a turbo with a pull through carb. If this is all you have, you're doing the best you understand. In the long run, the engine is being destroyed by too much fuel, gas or methanol, in the oil. This increases the blow-by, therefore needing multiple catch cans to keep the track clean. I know you have financial hold backs, but if you watch the big racers, you'll see a lot of them rebuild the engine after each race. I know you're not able to do this. Check your compression and see where it's at. Go from there -- but the biggest thing I want for you guys is to beat JOHN'S time. IIRC it is 91 mph. I know you can do it. Keep up the fantastic contend. Keep on Building on

    Great video,
    I have an idea how you can build an injection for the rail.
    You need a high-pressure pump from a diesel and the injection nozzles, you have to put the nozzles directly in front of the valves in the inlet.
    Now just coordinate the ignition order with the injection order, connect the pump to the engine and fill some two-stroke oil into the fuel to lubricate the pump, then there should be no problems with the fuel supply (hopefully).
    It is worth a try.😅

    I've been thinking about it, and with the design of that car you're just a few parts away from being able to make a cool 2 speed transmission pretty easily, similar to a "chain-gang" Frazer Nash. Run the jack shaft through to the right side of the car and add a sprocket set with a different ratio to that side, connected by a clutch - I was thinking a pneumatic fan clutch from a semi truck out of the junkyard would do, those transmit 80-100 hp for a million miles. Then on the left side of the car put the drive sprocket on a sprag clutch - you can appropriately sized ones from McMaster Carr. When you put the air to the pneumatic clutch you'll be in high gear, and the sprag clutch on the left side will freewheel. That could give this thing some top end charge!

    On that pwk carburetor,it has a power jet circuit built in already. The problem is it’s not metered. I tap the hole on mine to accept the pwk slow jet and screw the brass plug back in the top. It sticks down in there for enough to draw fuel out once your close to mid/ full throttle where the turbo needs the extra fuel. This way you can add fuel where you need it to get your best e.t. Possible without having to large of a main that’ll bog the engine down. Try it, you can always remove it and also add from 31-55 slow jet or larger if needed. Good luck

    Excessive blow by could be caused by leaking crankshaft seal. The big block Vanguard crankcase typically operates at a vacuum - if there is small hole it will pull in air and seep very little oil to exterior, which causes blow-by CFM to double or triple. I'm not familiar with Predator 670 engines but guessing they also operate at a vacuum.

    Sprint car racers (and many drag racers) use a device called a weather station to measure the air quality in terms of temperature, humidity and barometric pressure. It then calculates a metric called "density altitude", measured in feet, which is used to gauge the general quality of the air as it relates to oxygen content for the purpose of engine tuning. The lower the density altitude, the more you need to richen your engine tuneup. Your program would likely benefit from one of these weather stations.

    I know you guys are working on going to fuel injection eventually on the rail, but have you considered going from a large bore Mikuni style single throat carb to something more like a Weber or Dellorto carb? I know you guys like the flat slide carbs, but It would appear you've got a combination of a off idle flat spot and a metering capability / flow problem across the rpm range. Going to a carb design with a booster pump and/or multiple smaller throats would give you a higher signal response in your venturis potentially causing better throttle response under load. Heck, you might even consider going to a Holley - Weber design with progressive linkage? most of those are in the 36/38mm throat size, come with a booster pump, and a power circuit. Just a thought.

      @@garyhowe88I agree. Fueltech is bottom of the barrel and very outdated. I run Holley on everything because when I tell them I putting it on something different, they seem to be very interested and really want to help. I’ve actually ended up meeting 2 techs I’ve worked with from Holley and they have become good friends of mine. Very cool people and extremely helpful. Fueltech needs a major upgrade or they just won’t be worth using on anything soon. Haltek is great too, but I’ve gone to Holley on everything.

      Or... Stop messing with methanol until they've maxed out on 100 octane, which they haven't. I bet they could go faster on a well tuned carb and 100 octane than they have with the poor methanol tuning.

    Here is an idea for you on the rail, go with a dry sump oil system with oil jets in the crankcase from an electric oil pump. Since it is a small engine a transfer pump should work. Using two smaller turbos, one for each cylinder with dual carbs with independent intakes treating each cylinder as it’s own engine. Also go with an automotive coils on each plug using a crank sensor eliminating flywheel ignition and making it hotter.

    You need a vent for your oil catch tank. Currently, your Gatorade bottle is restricting flow by not being vented. Also, configure crankcase catch tank below crankcase exit level. Take one or two teeth off driven axle sprocket, add one or two teeth to drive sprocket. It "sounds" like your rpms and spped are topping out and flat-lining 70-80% down the track.

    Take a notebook with you, keep track of the temp, humidity, and the jets you’re running. Whenever you pull up to a track just compare notes and put the closets jetting to your notes you have. That will give y’all a great head start so you can experiment from a semi close ballpark number.

    Methanol is way more forgiving on tuning than gas. What you said at the end is correct for tuning methanol. I’m guessing the fuel signal on that intake is so weak your having to run a bigger jet because the vac signal isn’t strong enough to pull fuel through a smaller jet. Also with methanol you have to run a lot more ignition timing at the flywheel. If your running the same ignition timing for gas and meth that is a big problem. Meth burns slow need to advance the timing .

    @majorwedgie8166 Рік тому +1

    Your not seeing the issue, the reason you run methanol is for the high combustion pressure. The higher the pressure gets, the hotter the combustion will be. This is why you need those monster carbs on old super charged engines, so the extra fuel cools down the combustion temperature but doesn't turn black like it's too rich because of the heat. I learned this lesson trying to run a Holly 650 on my 400 Chevy stroker. Without adequate fuel to cool off the combustion, I would pre detonate like crazy until I put an Edelbrock 750 on it.
