Turbo 670cc Dragster RETURNS and Runs Quickest Pass Yet!

[@CarsandCameras]

We were blown away by it's performance for the first run of the year!

[@JamesRK2]

Imagine how much better it would be if yall fuel injected it

[@Just-InTimeRepairs]

I thought you guys had 1.8 million subs? Now I'm seeing 1.1m.

[@seano2178]

Add 3ozs of Marvel Mystery oil to the tank when you run the methanol. It will protect the valve guides in the motor and the slide valve in the carb plus pickup close to a point or so in compression.

[@Copperworks.]

what happened to the riding mower that the 670 was on i started watching when you where building that and you guys are the reason that I'm into go carts and mini bikes

[@87mustang87]

Track will probably stop u at 7.0 in the 8th due to needing a thicker frame an cage around driver.

[@BobbyOfEarth]

If you guys switch to Fuel injection, the controller will monitor and adjust the fuel delivery to balance the EGT's of both cylinders. Plus to get max Hp...

[@_CryptoNoob_]

Or just switch that junk motor out

[@Rattus-Norvegicus]

They should take it to RobotCantina so he can do the conversion.

The dragster is my favourite vehicle in the fleet it’s why I subbed to the channel I can’t wait for you to run that 100mph in the 1/8th mile

[@minties51]

i’ve been a fan since 400k subs, and i’m really impressed with the transition from building ludicrous go karts to building these absolute beasts! you guys are incredible!

A steal screen inside the intake before the split in the cylinders will help with fule atomization

Old school hot rod trick, but makes a massive difference

[@freedomforourfallen3755]

I’ve raced 2.3l. Fords. Dirt track. The fuel would sling real bad. We put in sheet medal. Bent it to make each cylinder get the same amount of fuel. I do like this build. So sexy

[@agkracing140]

With the popularity of electric cars growing, kids of the future may never know that incredible feeling when your project engine fires up!

[@LuxGamer16]

I nearly lost hope for a video of it again. Glad its back.

[@Amenhir1]

I just ordered my first t-shirt. It's the first time I've ever ordered youtube merch. Thanks for the years of fun videos. Next stop 2 million subs!

[@jdshanahan4215]

You guys should sponsor a local kid that drives a jr dragster. Like build them a quality race engine for their class and they can rock you decals.

[@thomaskrehbiel2946]

“It will be fine”. You guys crack me up!!

[@flightpath22]

Congrats all on an excellent effort all the way around. Also, congrats Charles on a spectacular first run on asphalt, GREAT photo…that’s a keeper! Good to see everyone having fun and able to do so safely. Keep up the great work and content, way to go boys!

[@rayleon8861]

Great Job, need to change the air filter too restricted.

[@harryjohnson2]

FINALLY! This is what the people have been waiting for. This is by far my favorite project

[@fastflat4]

I'm sure not all will agree, I love these videos of crazy drag builds and what not. But I miss the old smaller realistic builds for the grand pre. The average fan can't custom fab, but we can buy a go kart and do all the bolt on mod fun like the older videos. Either way. Always a fan and will watch all the videos

[@eckdirtbiking5113]

Yes I’ve been wanting to see this back for a while 🎉

[@lukefrost1189]

Glad to see the rail back again, can't wait to see it run when you've got the fuelling sorted.

[@Tater79bj]

I think Charles should start his own channel. I'd totally watch it 🤟

[@mychaleporter6806]

Also needs a velocity stack....filter constricting n crunching

[@toreyweaver9708]

20:38 that thing moves out! Holy cow the drag rail has come a long way. Please keep improving on it. Love to see the progress. 💯🤘

[@gavincline209]

I’d say get a stand alone wideband O2 sensor and data logger onto a SD card if nothing else. It will show you pretty good where ya need to adjust the fueling to on a pass. Meth is tricky, very easy to run too lean and blow it up in an instant.

[@TekedixXx]

So excited to see another vid on this beast. Idk why this project of all of your projects is the one that captivates me the most...

[@ninjasuperman9538]

That switch probably shorted out when Ike saw sparks flying

[@mixerman1]

I have loved this thing from the getgo. I wish it had a draw through supercharger and EFI. I bet Charles was in the 9's at around 70mph

[@joshuabuilds3051]

Thats 6 pounds of rotational mass. Much more significant than other weight savings.

[@lilldebby2592]

No way y’all are at my home track Piedmont dragway 🤙🏻 hope to see y’all there one day

[@kyleewert5630]

DUAL CARBS. Equal fueling, ability to get the engine the fuel it needs since you have been lean all along and drilling jets and choking the air down to compensate

[@oldcars46]

I really enjoy your show. The guys are out there. Having fun and doing the best you can and get good speeds. Keep up the good work. Great show

[@jesperwall839]

Yeah. Also much smaller carbs, so they can get more fuel and higher airspeed. Methanol requires 3 times as much fuel as petrol. 12:1 for petrol, and 4:1 for methanol. You also need different spark plugs when running methanol.

[@adamr9215]

Dual carbs won’t help when they are both running through a single turbo. They would probably have more problems if they tried to go to a blow thru set up. They would be better off putting an EFI set up on it.

[@ogrefreak5222]

​@adamr9215 of course they would, but that's a project for later. And you can dual carb. It's called a blow through. Not ideal to split the turbo output to two possibly leaky carbs but certainly doable. It's closed loop so pressure would be roughly equal. Heck twin turbo, crossover exhaust (turbo feeds opposite cylinder). That would be something interesting lol

[@adamr9215]

@@ogrefreak5222 You aren’t that smart, are you? I mentioned blow through carbs, so don’t go acting like I didn’t. Also, to go twin turbo, they would need to find even smaller turbos to spool decent.

[@kcrichton7485]

I love that you guys are still building this, you should do ceramic bearings in the wheels and axles etc next, its hardcore enough for it

[@FeatheredDino]

For the blow by issues causing oil to spew into the intake, you could try venting the dipstick. Drill a hole, thread in a 3/8 hose fitting (or whatever size you want) and run a fuel line up high somewhere. That'll help alleviate a lot of the pressure that is causing oil to be forced out the crankcase breather and into the intake..

[@terminalpsychosis8022]

The green drag machine is legend. Running better than ever too, after a few bumps. Just gonna get better.

[@Jakefrc]

EFI will really bring that thing to life

[@johnmorgan1629]

[@dwartfarquart9590]

You can buy k&n filters with an internal velocity stack in various sizes. When I ran motorcycle dirt track, they made a significant difference in midrange performance.

[@user-yg1uw5lo1n]

I watched a guy balance fuel by mounting a fin under the carb inside the intake. With a few snips and bends and by checking exhaust temps he got it "good enuff til the next race".

[@P8FPV]

Great stuff nice to see both run together

[@jeffmurphree2937]

OUTSTANDING!!! Have you considered having a car body back from the fire wall around the driver? You could add a cool paint job on it!

[@erikcourtney1834]

If y’all would up the rpm’s at the line it would wheelie better and would definitely 60’ way better. Don’t leave the line with little to no rpm, especially with a turbo. If you can’t hold it still do dual brakes on the rear or raise the stall more.

[@CLCIII]

EFI ON A MOTEC OR HOLLEY OR FUELTECH AND in mid to low 7's for sure! Possibly your 6:70 @ 100+! I WANNA SEE IT! As Always, May God Bless you and yours! 😇

[@100mpgus]

The dragster videos are the best videos you have. I love it.

[@nickmassey9104]

That rails awesome .Charles did good. John for designated drag race pilot

[@HellmuthsHotRods]

I think the car is pretty well set up based on the ET vs MPH. I have been racing my bug in 1/8 mile for decades from as slow as 9s, up to 7.30s (NA) and as I said your ET/MPH is right on. ET is generally an indicator of chassis setup, MPH power. My best is 7.37 at 92, so I think your 6.70 to 100 is close. I think that will be a bit over 100 mph actually. It's fun to widdle away time like this!

[@micahhittinger6083]

Losing that catch can lid tells me that boost was going around the piston rings. I had a 91 turbo Eagle Talon that would pop the dipstick out because it needed a rebuild. That was on stock boost.

[@Jon_Flys_RC]

If you run into a clutching dead end reach out to heel clicker clutching. When it comes to snowmobile / cvt transmission systems they are infinitely adjustable in multiple points of the shift curve.

[@bigunone]

I still say you need to adapt a more tuneable carb something that flows more CFM with more jets available

[@toomuchtracy]

Yes!! Always look forward to watching you guys

[@ronniedale6040]

I tried the mc carb thing on draw through VWs take it from me the best thing you can do is throw a Weber idf on there in a blow through configuration with a divided intake. I made zero carb mods to mine for boost. Easier to tune and your fuel robbing issues for the second cylinder will be completely cured. You may also be overpowering the needle and seat on that bike carb. When they say gravity feed only they mean it.

[@KENNETHREAGAN]

I can’t wait to see what you do with the drag racer, but honestly I want to see you put a flat track tire on that minibike and a wheelie bar and see what Charles can really do

[@Huntinghogs]

Have ya’ll thought about using a downdraft Webber with a split plenum intake? Might help with fuel delivery to each cylinder. Might be easier to set it up as a blow through instead of a pull through.

[@dakotafox617]

When boosting small engines it is really beneficial to have some sort of intake plenum volume so you have equal fuel distribution and intake pressure for both cylinders

[@hokirwinsor8775]

Only really necessary on a single cylinder motor

[@csandy500]

I told you guys you were loosing spark last season. Look at your old night run videos and you can see this thing sparking on the dash. Good run!!

[@hunnybunnysheavymetalmusic6542]

[@jasonpetrich4141]

So you guys need to build a test hit lane out on the back 40. So you can test the rail before you get to the track and what ever else you might need to test on a drag lane 🤔 😏!!!!

[@shrapnut7612]

Great vid guys, I was hoping it would be on this rail, after seeing the teaser from last week.

[@danf4616]

That Hayabusa drag bike was sweating it. Charles almost took him on the mini! 😁😁

[@electrogeek1124]

Need to put the carb after the turbo. I believe the centrifugal force the turbo puts on the air as it passes through separates the air and fuel mix and causes the fuel to go into one side.

[@hobbs37110]

im ready to see the new rail run boys.

[@jaredmcquiniff5362]

[@slamboy66]

Just like when I tune Harleys, you have to fatten up the rear Jug . More fuel cools it down the rear cylinder. You need dual carbs. 👍👍👍

[@timbrindley451]

we have drag racing here in south east of fort worth off mansfield hwy

[@yellowflyer37]

Hey guys, love what you have going here. Just some thought on your fuel distribution issues, having a largger intake manifold would help. The bigger the plenum volume (aka) "bucket" the cylinders can draw from would mix fuel better in your application and the cylinders will always have "literally" as much air as they will need. Boost (pressure) is importand AS WELL as the quantity avalible.

[@AndrewSkingsley-t6b]

Great to see the rail back !!!

[@ryanbarrimore9703]

Sounds like the ignition is breaking up at high rpm. For the methanol you need a lot more power from the ignition to ensure that you burn all the fuel in the combustion cycle. My advise is to someone get more power to the spark plugs. Drag cars use MSD ignition stuff and they create huge power. Maybe worth a look into.

[@Blurgamer17]

I think a dual-carb or EFI setup would be the way to go from here to allow your rail to breathe better than ever. This has always been a great build over the years and it can still go a long way.

[@aleks_jones]

Finally! Been waiting for this moment for what seems like forever! Keep up the good work bois

[@danielfrazier840]

Get a Jr gangster catch can (its a big like 2 inch pipe on the back with 2 breathers onto the bottom of the pipe) the breather filters are on pipes that extend into the large tank (pipe) with 2 an lines and running to it and a an cap for a drain on the bottom. They hold probably 3 or 4 quarts before it will leak and the engine only has 3 quarts total oil.

[@danielfrazier840]

They are low and on the rear most of the frame

[@NAW_Garage]

I have a turbo cavalier that has gone 7.73. If you get into the 6s before I do I'll be even more impressed than I already am lol

[@RollingThunder808]

You could try increasing the valve spring tension and test it on the dyno. I still think you're having valve float at the top end. Maybe dual springs would work.

[@Thomas63r2]

If you do get a 6.7x e.t., I would expect at least ~ 102 to 103 mph. Good luck - and I can't believe how good it sounds, it will sound even sweeter when you get it running right.

[@outrageous4989]

Moving the battery to the front might help with steering... besides, never hurts to have ballast on the front.

[@tomt165]

You guys need to run some inch and a half flat braided wire to everything to make a good negative ground. Like you are now someone close by with a real strong CB radio will cause you all kinds of problems. I've seen plenty of radios that would cause garage doors to go up and down, this isn't far-fetched. Real good braided flat strap will take a lot of that possibility out of your electrical system.

[@BIllMcCambridge]

Great job guys. I like the idea of changing to blow through carb. The meth will cool the hot turbo air. And you will get better air/fuel distribution. You may wanna put an air fuel data logger or egt data logger. Yall are guessing whats wrong. You need data to make gains. Love the channel Thanks for sharing your talents and adventures!!!

[@jonathancrissinger2301]

[@lonestarracingenginesgokar2202]

I remember you getting those front wheels at Pate!! They look good !!!

[@AdamOpheim]

Might try a flat steel divider right after the carb. Similar to the turbo carb hats they use. Helps divert fuel and air equally to both cyls and would be quick and easy to install. also boost is gonna pressurize the crank case. YOu don't want to plumb that back into the intake. Get a good catch can and you don't need to plumb it back to the intake. Good luck!
