What HP engine would you think to be the max to run safely? What is the best engine maker? I always go overboard and would like to have the largest engine with the most torque right off the bat rather than run...upgrade....run....upgrade. I want to do it right the first time but I don't want to break stuff every run! There has to be an indestructible 32cc torqummonster right?

I have MT pro with 32cc engine, its reliability isssues and drove me to my max.
 
Good luck getting a response from ONB . I tried contacting them via email a few times but they never reply. One wonders how they even stay in business, lol.
 
I have no trouble getting in touch with OBR. I have their 32cc stroker at 9hp on my MT. It’s a beast. I’m trying to sell the truck now but I can’t post it on here.

Pick up the phone and call them during the week.
It’s worth the effort to speak to them on the phone. They can make recommendations, and discuss issues on the phone better than email
 
OBR customer service is second to none
I've had no issues they answered all my questions. They told me what engine that would be good that wouldn't break my stock drive train on my MT so contact them

What engine did they recommend because I’m looking to put a bigger motor on mine but worried about the drive train parts breaking they break now with just a upgraded carb and exhaust

x2. looking for a direct replacement on the v3 hy motor...lets us know tks.
 
I honesty think anything over 6hp will shred driveline. Check out any youtube videos and read the comments. Most of the guys admit they shred diffs, cups, axles etc. every run. It gets expensive as is. I run a stock Zenoah g320 and it is plenty power with a ddm dominator side mount pipe and a 990 carb.

How does it hold up with that motor I have 990 carb 8000 clutch jet pro pipe and I’m breaking driveline a lot now so I would think with the 7.5 it’s has to tear the driveline up.
