So most of you probably noticed by now that virtually all small engine driven items are now sold with engine size listed in CC.
Doing some shopping for a few new small engine items and it occurs to me. Do i trust the new CC numbers anymore than i trusted the old HP numbers from before?
i submit
Amazon.com: Portable - 7000 Watt / Generators / Generators & Portable Power: Patio, Lawn & Garden
all 7K generators.
I see 389CC, 410CC, 420CC... and some generic "13hp"
i also compiled a list of conversions from various internet postings.... I post all of them as the conversion is not an exact science
205 cc = 8 to 9 Gross Torque = 5.5 to 6 hp
250 cc = 11 to 11.5 Gross Torque = 7 to 8 hp
305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp
342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp
123 cc = 4 hp
179 cc = 5 hp
208 cc = 5.5 to 6 hp
277 cc = 7 to 8 hp
291cc = 9hp
305 cc = 9 to 10 hp
342 cc = 11 to 12 hp
357 cc = 13 hp
420 cc = 13-15 hp
123 cc = 4 hp
179 cc = 5 hp
208 cc = 8 to 9 Gross Torque = 5.5 to 6 hp
277 cc = 11 to 11.5 Gross Torque = 7 to 8 hp
305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp
342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp
357 cc = 14 hp
420 cc = 15 hp
so are the 410CC just 389/390 overstated? Is it possible in todays world to take the same 420CC engine and really have that 13-15hp range depending on???? (tune?)
can you trust a harborfreight 420cc engine to put out the same power as a honda 420CC (notice i talk about power output and not longevity) Why/why not?
What say TBN?
