To clarify, the wattage ratings that the motor can use/dissipate is the same no matter the number of cells.
When you increase voltage from say, 2s to 3s lipo, current will go up (assuming the same gearing), which will cause wattage to go up as well. If this wattage is higher than the motor can handle, then it will overheat. If you increase the cell count, and reduce the gearing, current can drop to approximately maintain the target wattage.
However, our setups are "peaky" by nature, so you'll have high power bursts, and much lower power for normal running. If you pull 1500w 1 second bursts every 5 seconds (20% of the time), then pull 250w for normal running (the remaining 80% of the time), your average power consumption is 500w.

Good question and input. I'll forward this to the ED (Engineering Dept  ) and see what they have to say.

Yeah that wouldn't make sense that the wattage is the same no matter the number of cells, because for instance, we all know that a 2000 kv motor on 6s is at least as powerful and efficient as a 3000 kv motor of the same design on 4s.

I will say first that i have no problems with novak's, they are good starter systems, with potential for racing, perhaps a bit better than most high-end brushless setups. I love how Novak seems to have matched Nitro's power to weight ratio, Most high-end unsensored setups may be overpowered. That said, the origional poster may want to get a stronger setup. a 14 pound muggy may be a bit too much for the little (380 diameter rotor) Novak hv to handle. Sorry Novak two, but i think the HV, even the 7.5 or 8.5 (whichever is the highest wind) would be in a bad situation
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise

Well if you're really in love with novak then you could get two hv systems to put in your truck. :)

I really think the main complaints are: That you guys were a bit behind on Lipo cut-off, and the small diameter rotors in the MT motors. I started my brushless adventures with an HV system and will never trade them memories for anything, But i wanted more power and a Lipo cut-off, So i went mamba and eventually to quarks for my MT and HV needs. I still love novak's and will consider one for racing, now that the Lipo cut-off is in the esc. I'm hoping to run a G2R revo or E-revo next year in Nitro classes

I'm just telling my story, I never said anything bad about Novak. But for future eference, I'll use brand-M and brand-Q. As I said, I wouldn't have any qualms about running a Novak in racing. I think the highest turn motor would be perfect for 4s Lipo in a Nitro mosh pit of a race
Sorry if i offended Novak in any way

I asked Bob and he said it's probably like putting a Volkswagon motor in a Hummer. If you gear it correctly, it will move ---but very slowly.
He said 2 HV Pro Systems would do the job.

No reason it shouldn't. Being as light as the slayer is, you could gear up more than on a revo or maxx.

Novak claims 40 mph even with their 8.5 turn non hv motor.

Novak doesn't leave a lot of room for gearing options. If that is their recommended gearing then you are pretty much stuck.
Of course I am assuming you are using 2 x 2s packs for 4s total?
My recommendation would be to look at the MMM combo or the Tekin RX8.
