I have a tsf2021, I would love to rig up one of those tsf2421s. What horse power motor would I need? 27or 29 I'm guessing.
 
You can power that with a 24 HP motor. Here is a link that will help determine what power is required for various pumps. http://www.envirospec.com/pdfs/pump.pdf

Or:
Power Plants, Power Requirement Formulas
Pressure washers are generally powered by gasoline engines, diesel engines, propane fired engines, or electric motors. Force created by the power plant turns the pressure pump, which in turn moves the water. A power plant must have enough force to continue to turn the pump crankshaft when the pump is pushing water out its rated flow and pressure. The following formulas are used to determine how much power is required to drive a specific pump. The power is measured in horsepower. GPM x PSI then divide by 1457 Equals EBHP (Electric Motor) GPM x PSI then divide by 1100 Equals Gasoline HP (Industrial) GPM x PSI then divide by 900 Equals Gasoline HP (Standard) GPM x PSI then divide by 1260 Equals Diesel HP Other useful formulas: HP x Constant then divided by GPM = PSI HP x Constant then divided by PSI = GPM
