Guys, try a small holley two barrel. I know it may sound a bit large, but a 350 two barrel may be your ticket. especially since you are drawing through. give you much better fuel control and more reserve in the bowl. and a pump shot for launch.

[@modeverything1]

I would look into a microsquirt/megasquirt myself, then you can control your fuel/timing and most likely get away with pump/race or e85 for fuel. Love the drag rail series!

[@BCDriven]

For future reference, instead of drilling holes in the vacuum line which could potentially rip open larger and let the boost run away, add a vacuum "T" to the line. You can experiment with "T" and "Y" fittings and if you wanted a bit of adjustability in between you can add a line to the vent part of the "T" with a little fuel shutoff to dial it in. Just a suggestion I havent seen in the comments. The main thing is you don't want that boost line to the wastegate to fail or it will just go kill mode and send all the horse-torques to it.

[@jdshanahan4215]

You beat me to it. Awesome suggestion.

[@adamr9215]

When you run alky, you need a good carb that will take the corrosive alky and nitro without dissolving. All cheap China carbs are made of pot metal, not actual aluminum, so they will not deal with alky. Time for a Lectron flat slide instead of cheap trash. Also, you never add nitro without having it dialed in before you use it. You still shouldn’t be running nitro because you haven’t figured out what you are doing yet. And, when you aren’t running nitro, you can run M5, which has oils and additives to keep it from being corrosive. Once you get it dialed in on M5, then you start adding small amounts of nitro and tuning it as you go.

[@oliverscorsim]

If you guys would like to check iv called every issue before you've had it. You need brass floats (easy to make). When Charles moved the wastegate he took all the preload out hence the low boost they all come at 15 psi more or less. If you take your other turbo and measure the mount to the flapper it's longer than this one. You can also very easily check pop off pressure with a leak down tester or air pressure regulator like for painting and a gauge. It should crack at 13 fully open by 15.5. that tiny hole Ike drilled won't change boost on that tiny turbo a 3way t with one open to atmosphere will give you about 18-19psi unhooked it will get to 20-22psi. I add a nipple to the bottom for actual control. Both hooked up will make 28-30 psi and just the bottom I get about 50psi before the wastegate blows itself open. For more you need a bigger turbine housing and the compressor wheel would do good to have the biggest exduser you can fit so it's not trying to melt itself. Once you get it running okay and get the boost up to launch use the foot brake some but be mindful your heating the clutch and belt. This will give you some boost off the line. Your catch can should really vent to the air filter if you can help it. Makes the crankcase pressure way lower helps rings seal make more power and not leak so much. I personally use e85 for all of the reasons methanol is a pain. Meth is better yes but not by enough to justify it to me and I'm now compound and boost is safely past 60psi just chill the fuel with dry ice and youl be fine on intake temps. I think your ignition is fine for your goals tbh but I'd invest in a real carb. I'm in Wilmington if you guys would like some parts I mights have a carb that would work for you but I'd go hsr all day on this. As for jetting if you bring the whole thing I have every size you could need and between me and my dad were some of the best motorcycle carb guys around so some quick jetting wouldn't be hard maybe an hr. Now one thing I am very concerned about is ignition timing control.. do you have any? Even a simple cdi you set a curve to would be better than nothing.

I suggest getting a standalone controller for your ignition, this will allow u to set an rpm limit. This shouldn’t hurt your boost because your air is controlled by the carburetor and as long as that is wide open the turbo will try to build boost so you may be hitting limiter but you’ll still hold boost

[@limprooster3253]

Would also allow them to have a timing curve instead of the static timing their flywheel key is at. Probably pick up a measurable amount of power, or at least require less boost

A belly pan under the engine could help catch any lost oil if you need it. I knew that Methanol would be an issue but never did I think this fast. Alcohol and Methanol "Eat Parts". Anything plastic/aluminum or rubber is at risk as far as I know. You got this.

[@adamr9215]

The nitro is worse than the methanol. And they shouldn’t even have touched the nitro until they have it dialed in on straight methanol. It’s just like trying to run nitrous with a bad tune, bad stuff is gonna happen. Then add in the fact that they are running cheap Chinese carbs that aren’t even made from actual aluminum, just cheap pot metal, they have set themselves up for failure. They need to ditch the nitro methanol and go with M5. It’s methanol with 5% corrosion inhibitors and top end lube. Once they get dialed in on that, then start adding nitro in small percentages. I really don’t think this engine will handle much more than 20ish percent nitro when it’s tuned right because the stuff is violent. Right now, running the nitro is just making it even harder for them to get right. It’s like they looked up some info on running nitro, then decided that they would do everything you are told not to do. And there is a huge no-no that I’m surprised they weren’t banned from the track for, or even arrested for. Using a fuel pump that isn’t rated for nitro is not just dangerous, it’s a crime. It’s an actual ATF law because of threat of explosion. By using nitro in a pump that wasn’t rated for it, they created an illegal explosive device. Just connecting a fuel pump not rated for nitro to a tank that has ever contained nitro is a felony. John Force tells a story about one of his crew members getting 25 years in a federal pen just for trying to use one to transfer fuel from a drum to a gas can. He never got a battery on it before he was stopped, but he still got 25 years.

[@ryanhogan6509]

Boosted boiz just got theirs running on fuel tech 550, fuel injection, on a single cylinder

[@yrmoma]

PSI isn't a sign of boost. It's a sign of restriction. It's not uncommon to have PSI levels drop on bigger turbos. What you're looking for is more airflow turning into more power, and that's really hard to tell outside of a dyno. I'm probably describing it wrong, but check into it.

[@SoI_Badguy]

so many people miss this

[@dannyfraser8850]

You need a 2 step so you can launch that thing and so you can build boost for the launch. I love that you guys are drag racing now.

[@79huddy]

They could solder in a msd chip inline with a thumb switch to switch from the chipped to unchipped side to interrupt the signal side of the coil that's how we did it on H.e.i distributors when we had to run stock ignition system in claimer class racing run it on the chip the whole race flip it off on the last couple laps and give it hell to the finish

[@PuckFNT]

Have you guys measured the emulsion tube diameter for the meth carb setup? The giant main may not be fully giving ya what you think if the emulsion tube is the new restriction. Nothing to do with the sputtering issues, but could potentially allow better AF mix with a smaller main+larger emulsion tube while giving the same volume of fuel.

[@PuckFNT]

@sourand jaded Tomatoe Tomato - emulsion tube and needle jet have been used interchangeably for years by virtually every manufacturer and hobbyist.

[@cs-gj3yf]

the gt15 waste gate pressure is 13 psi, when you poked holes in the gate tube you made a boost leak, keep in mind you want boost and backpressure balanced, also try to build boost before you leave, i love the videos tho!

[@budddove6480]

If you want more boost on the fly, just take different sized vacuum T fittings and add one into the waste gate line. The hole Ike made isn't near big enough to do anything. You could also put washers on the wastegate linkage. Id just order a 15 dollar manual boost controller and call it a day. Also, I think you're having a fueling issue. Before you change the electrical, dial back the jet some and get your boost back to that 8lbs. Great video, thanks for the entertainment. ((Edit)) I commented to early ...lol That will definitely cause a fueling issue.

I hope you get it sorted, I love seeing this drag rail. Years ago when I raced carts, we ran methanol in some of of them. We would drain the tank and run pump gas through it at for a while at the end of the night to combat issues like this. The methanol will cause all kinds of problems if you leave it in there BUT that wouldn't stop it from happening only prolong the damage. It was just a part of racing, you learned to keep spare pumps, diaphragms, hoses and tubing around and change the oil between every heat if allowed. Back than, pump gas was actually gasoline, not the junk in the pump today and I believe they make better parts now days that will hold up a little better. Good luck fellas, I hope to see more.

[@circut3722]

You guys need a LECTRON carb setup for the fuel you are running, It will solve your fueling problems. You will also need a fuel pump designed for E85 and fuel line for E85 . Love watching your channel and looking forward to the next video .

[@elivestin5353]

I agree. A LECTRON carb would definitely be a safe bet for being able to tune a methanol field engine.

[@DarkLinkAD]

Methanol is far more caustic "Corrosive" than Ethanol or E100

[@fellenXD]

"Boost-control" bleed valves are dirt cheap and would make adjusting boost much easier, while avoiding a vacuum leak when off boost. You can also get knock-off OEM VAG boost control solenoid valves (for like Audi tt and Volkswagen 1.8t engines) for real cheap as well (like 15 bucks on Amazon). Wire it up to a button and you will be able to manually get extra boost if you want, or help build boost before launch by bypassing the wastegate completely.

[@donmears4090]

Some ideas for the dragster 1. Limit the amount of runtime between oil changes(if your running nitro its murder on oil). 2. If there is one available, install a hotter ignition source (capacitor discharge?) 3. Install an air-fuel percentage gauge and video its readouts to include where the car is on the track. 4. Increase air intake capacity by using an aftermarket two barrel carburetor equipped for methanol(300 or 500cfm Holley?) or using one of the smaller turbochargers per cylinder with a carburetor on each.

The methanol is terribly caustic. When we raced Briggs engines in go karts, we drained everything after the night or pump and carb would be ruined.

Take a good timing light hooked up, and a rubber band around the trigger, with you during the pass, and keep an eye on it if you suspect an ignition problem. You'll see skips in the light that correspond with the misses and pops if the ignition is to blame. If you see a constant, smooth light, then it isnt the ignition. I used to do this with high-performance 2-Stroke outboard motors to diagnose ignition system issues when they were running rough, and it works like a charm to determine if it's an ignition or fuel related issue.

Take a look at a channel called boosted boyz who just put their go-kart on a EFI system. Granted it wasn't cheap but I believe it will unlock a lot of things for you. Also amazing job of the project this rail has come so far in the last few years when you first built it. Long time subscriber keep it up

You guys should check out what boostedboiz did with their turbocharged single cylinder go kart running on fueltech EFI. It really made a huge difference for them. And the setup looks really simple. everything is contained in a little gauge cluster.

I just love this series. By far your best. Camera work has really come a long way also. Bravo boys....

I'd try to get your hands on a Polaris sportsman 570 for the fuel injection system. It might work of be worth looking into.

Love seeing you guys live your best life, makes me smile. Keep up the awesome work!!

I would've thought that perhaps pinching the wastegate boost line instead of putting holes in it would help in stopping the wastegate opening without letting boost escape from the hole which could expand under boost pressure, awesome video as usual though love you guys!

Time for a compound turbo setup 👌 put the old turbo before the bigger turbo 👍 do powersports have a EFI kit? Hint hint..

we use methanol on our race go karts and drain the methanol completely out of it and flush it out with regular gas so nothing gets damaged. love the videos the dragster is gonna be amazing when everything is worked out

Fuel injection. Thinking polaris,motor cycles and other side by sides. Just a thought
