horsepower, torque, rpm... these are all estimates that manufacturers come up with to sell engines.
The TZ 18 IS the most powerful 18 that you can really buy at the moment. If on a budget, the CV-R .18 should be up your alley, its pretty darn powerful for less than 120 bucks. I have one in my tmaxx, but that maxx is junk! Couldn't keep the traxxas together long enough to keep the OS in it

If it was powerful enough to do a burnout on pavement for all 4 wheels on a TMAXX, its MORE than enough for your tornado
The OS 18-TZ. realy makes thows numbers they did a dyno with it and here is the article on it...
