Our Predator 670cc v twin powered dragster runs its fastest time ever at the drag strip! N/A, this modified high performance 670cc v twin ran a 9.92 in the 1/8th mile, and today with the turbo, nitro methanol fuel, and RZR transmission we ran a 7.89 at 91 MPH! We still need more fuel flow and some stall speed in our transmission before we can crank up the boost, but this test ‘n tune was very promising!

I really enjoy following this project but I wonder how fast it would be with a snowmobile engine to go with that CVT?
why dont you spin up the turbo at launch?
Definitely need to shave the weights and bring the hole shot rpm up and up the boost a few psi then ya be moving..sick build
I was close said it would go 88 mph
The burnout on that last run looked legit
I use to build go carts with motorcycle engines. The biggest challenge was not pulling a wheel stand. I built one with a 450 honda motorcycle engine. That's a pretty cool setup.
You should look into holley efi setup, they make a single barrel kit now that should work perfectly, will have to fab up intake but that’s the fun part! Also look into mega squirt or micro squirt efi
Need a 2 step set up on it like we did on our turbo snowmobile. Set it up to sit right before belt engagement. Then you can leave on boost
Hey do you guys want another Tecumseh 6hp? I’m just going to replace it with a 212. I’m not far from y’all.
You guys are doing a great job.
Have you ever read about"" The Great Chicago Auto Race"" from 1920's.
They had 2 low horsepower Stanley Steamer cars. Both were low horsepower (9 HP & 15 HP)!
They weight in at 3 tons each. Yet their top speeds were up to 115 mph in dirt, sand, gravel and concrete roads (lots of friction)!running 600 p.s.i.!
You guys are so close to what they had so very closely but your vehicle is so much lighter and can use a Harley Davidson 6 speed gearbox.
Or even hydraulics to run like a transmission! Hydraulics can go up from 600 p.s.i. to over 10,000 p.s.i. off of very low horsepower!
More transmission equals higher speeds!
Tip: more horsepower just gets you there faster!
9:54 that burnout look legit man ! You guys are getting that thing to go!!
Cool, but nitro needs load.
Try a big SU carby, it might be better suited to what you are doing. Injection would be the go.
Put a wide band O2 sensor on it so you can see what your air fuel ratio is!
Need to put an engine diaper under it so you don’t keep oiling down the track
Called it!!! In the video where you guys were doing weight reduction, I called 7.80 in the 1/8th. Now, that was also taking into account Ike driving, not John. I believe if you were able to get enough fuel into the engine, it would absolutely do 7.8X or faster with Ike driving.
Man I have been waiting a long time to see this Dragster actually move out like it I knew it could this is an awesome run good one fellas
Yall be careful drag racing and going fast is addictive
You should try to get a cvt from Cvtech that could be perfectly tuned for you and you will also gain alot more performance with it
been thinking about this change in gear , should had boosted Up instead
Piedmont, I love that place, I've announced there a bunch! Take Leon the starter a 4XL t shirt with a $50 attached to it next time you go and he'll forgive you.
Wish yall would do mini bikes again. Over past summer I took a bt200x and put a honda 250 2 stroke in it. I'd like to see yall do something similar to race. My bike is a rocket ship
Was this piedmont dragway?
Keep the good work up been watching yall sense day one be safe.
Wish y’all didn’t put spoilers in the thumbnails. Y’all are awesome though. Can’t stay mad lol
