A draggy will give accurate gps times as well as 1/8 mile and even quarter mile times. The no prep no time drag races use it to keep their times and mph to themselves.
Been rewatching the road to horsepower series got me thinking. A dyno session would be cool to see the differences between the 3 different hemi heads. The predator hemi, ducar/Tillotson hemi and the wildcat hemi. Using the same short block with the average build; billet flywheel and rod, .265 cam, flatslide carb. Even use the same thickness of head gasket (new gasket for each head swap). Would be cool to see the dyno charts to see what head works best at which rpms.
Go by distance. You start at roughly the same place each time so you can calculate a known distance using your footage from the previous runs and compare that to the new runs. Once you know your distance you can use your footage to give you a time and you can compare that over the various stages of the build. Kind of like a dragster.
I bought the wildcat 223 and a stage 3 kit from EC ,and the valve tools from you ,just waiting on the tools to show up so I can build my motor ,awesome videos ,keep them coming
Have you tried a bicycle digital programable speedo? I’ve used them on my karts in the past. First install magnet and sensor. Then You calculate the tire roll out. Then do the math formula it gives you. Take that number program it into the little digital screen and boom speedo. Live real time display. Every straightaway, corner apex, entry and exit. Like a motorcycle with a digital speedometer.
Respectable numbers. EC makes thee best billet flywheel and matches what the can manufactures state for timing. ARC is still good but have to buy a 2-3 deg key on top of the flywheel for some reason. Also thank you very much for being honest in the 0-30Mph issue. Always important to build the trust of your viewers and no worries as it wasn’t something anybody knew up front and great catch on the TEAM RBG’s part. See ya ✌🏼 next vid
Not every flywheel has the same ignition timing preset. It's not someone else fault when one buys the wrong one and has to use a key. Both of those comapnies make great parts that I would use without much question.
@@NubsWithGunssince you got it all figured out can you send me a link to an ARC bullet flywheel for a predator 212 WITH A 17 deg TIMING SET?? I’ll wait. 😂
@@NubsWithGunstroll games? No. It’s called don’t be commenting on shit you don’t know anything about. ARC knows 80% of hot cams suggest a 17deg timing so why make a 15 deg flywheel? Troll. YOU are the troll dude I commented, My comment makes sense and you come along with an opinion and no data to back it up. No shit nobody needs a key but it’s not easy setting that flywheel perfectly at 17Degs without one. Anyway I’m still standing on what I said. EC knows what the cam market asks for and ARC makes a damn good product but stupidly sets their modified wheels at 15 deg’s. Go back under your bridge dude. I didn’t ask your opinion.
Hell yeah brother. Non Hemi head for the win. Brand name like Hemi everyone thinks their fast. I’m like, oh well more flat valve heads available for me 😂
No doubt. Any non hemi head with $25 Champion rockers is going to have more power than the hemi head. But try telling that to the hemi head enthusiasts.
Thanks for the Video RBG. At what point does the charging coil get sacrificed? On an engine without a charging coil how do you suggest running light for a go kart?
Once again get a dragy. Ive been saying this in your videos and on the facebook group for 3+ years now. You (or your wife...cant remember) even replied finally on facebook in a post last year and said you would look into getting one.
A draggy would be the pefect thing to use. Its like a proper drag race time mesurement thing. I dont know how expensive it is but as far as i know itn not that bad.
Gps put the number up slower then real time . In my semi my garmin is always a tad behind my dash . When caught up its deadly accurate but not during accel or decel
It would be nice on these videos if you would give a an idea of what the motor would cost with the upgrades to this point and label out the dollars to hp for each stage compared to the previous. All in all great video tho.
For series 3 or 4 I would like to see a fuel injection build I know they could be a bit more complicated but it would be unique and we would see more efi builds
For accurate speed look into a GNSS. They're used for RC car speed runs, and will give you all the 0-30/60, ⅛¼mile times, and it links directly to your phone.
red beard i would love to see a video on porting the predator 212 hemi head i was following your road to horsepower series but i cant find very much info on head porting
They are running a sale on these right now. They are like $179. Shipping king of suck but That’s cheaper than buying the reciprocal kit to stroke your 212
I really would like to see the hp7hpx duromax 212cc propane build on stage 2. I got Inspired by your video on making a propane powered minibike, and now I have it on my camping bike. I plan on taking the governor off, but I don't know if I have to replace more than the flywheel and valve springs. I appreciate all that you do. Keep tye content coming!!!
That top speed is slower than my predator 212 hemi with the governor still in it just moved the spring to turn 5000rpm and I had a stock rear sprocket and a Chinese torque converter open filter and 3 stage exhaust rejet the carb for the open filter and exhaust and I got 56mph with the governor and I guess you can say it's a stage 1 I can probably go faster if I messed with the rear sprocket
Sky Rc “GNSS” I would say a draggy (I have one and they are accurate) but for this type of speed I feel like the gnss would be a little more fitting for the application. They are also half the price
I've been waiting on wildcat build,and I'm very satisfied with the power gains it makes! My thing is does EC carburetors or anyone else make a safe electric start flywheel? I know I'm not the only one who needs/ wants a built electric start engine. Help !😂
Like the new "Intro". Well done. Will you Please show people; 'How To Shave Their Woodruff Key' to advance or retard their timing? What did the sparkplug look like after testing? That will tell people how they're doing when you explain the color.Thank you for even reading this.
I build all my engines for kart racing and at one track they run a class stock appearing which means you can run any air filter, exhaust you want but the rest of the engine has to look stock. There’s not alot of videos out there on modifying the stock carb but there are several on the market in different stages. I would like to see dyno numbers using stock carbs in their respective stages.
@@ryanmannracing22 I have ran the gx390 carb just playing around I had to make a throttle linkage cause the push pull is backwards compared to a small block carb. On your motor with the 390 carb what head are you running and the valve size

I absolutely love that you’re doing these videos! I just got a wildcat 223 for Christmas! I have a pwk carb, gov delete, billet rod, cast aluminum flywheel, and an exhaust!
I have found out in the past by using a cell phone to monitor speed was a lot different due to the having to wait on the cellular data to come through versus the GoPro or a GPS device like a draggy or something like that there I would be more out to believe that the GoPro was more accurate than what the cell phone would be but that's just my opinion and what I've seen
Do you have a website or some type of contact info to get in touch directly to do builds for viewers/customers? I'm interested in this build specifically for my trailmaster. I really don't like getting into the engine and would rather pay to have it professionally done. I was thinking about having Go power sports to a build with the tillotson 212 but....😅 Any info would be awesome
Forget about the 0 to 30 times just do a 300 ft time and an eighth mile time. Take a rolling tape measure and spray paint on the road. Then just measure the time off of the camera
I haven't found an accurate mph device or app. But i do know that the ones you download are highly inaccurate. Google Maps is about the closest that i can say at being accurate, but have to set a destination to get it to pop up. I have an old Murray Outlaw that I put a staight axle on with pred 212 stock and cvt. Gps app says i do 38 mph, but i had a cop clock me at 45. Google Maps has shown 44. Go pro 44 to 46. I weigh 215 lbs. I've watched your videos for a long time and always felt something wasn't right. Either from what I've experienced or from yours. Hope you find something that works with accuracy!
So how much money do you have in this setup with the new parts you’re taking back off? I mean if the average joe is following the stages, you’ve got over a grand in the engine.
What engines to see in the future? How about us Canadians eh? We have an engine called Power Fist widely available, but nobody doing videos on them😢..(p.s-power fist is Honda clone but still better than predator…)
I know on Amazon they sell this thing called a draggy. I will do 0 to 30, and more. Ive just seen another youtuber use it for his 0 to 30 times. Not sure what he uses for top speed.
I have the Clone Predator from back in 2008. Still going strong, it only runs a car alternator once a month to charge my backup battery bank. If I wanted to Stage Up this bad boy and get better fuel efficiency, how could I do that?

Nice job with the overlay on the dyno graph! But I'd still love to see stock included also. It just helps put things into perspective
Sky rc makes a cool one for rc cars. It'd work perfectly
Might have to use this similar build on a motorized bike frame should be interesting
+1 on draggy! I have had one for almost 5 years and it is very accurate.

For trapping accurate time to speed you just can't beat the old stopwatch and radar gun combo.
