First - you may find this interesting. The TS2021 that General Pump the U.S. arm of InterPump/Italy rates the TS2021 at 3500 PSI. InterPump the manufacturer rates the pump at 2900 PSI.
Second - you will always be able to get more bang for your buck with a gear drive pump. There is a HP loss when using belts.
TS2021? Great pump and the 5.6 @ 2500/2600 PSI is an awesome set-up. The 13 Honda is an excellent engine but as someone else said the Kohler will give you more muscle/torque overall.
Kohler just came out with their new 7 hp engine. We are presently using it on our Cyclone system. It carry’s a 3 year parts and labor warranty. They will be coming out with their new 9 HP engine and their new 14 HP engine in the next few months. If you can wait you will find both to be an excellent choice for the 'long run.'
On our 18 - 30 HP Kohlers we use a Kohler electronic 'idle down' that works flawlessly. Simply release the trigger and the engine returns to idle. The calculations show that it you use this 'idle down' equipped engine 6 days a week that in one year the gas savings alone would be over $2500.00. The nice thing is that they way we purchase our units you will be able to obtain one of these for less that what you would pay for the same Kohler (less the idle-down) somewhere else.
Another note about the TS2021(B) that is advertised. Although it is the same identical pump as the TS2021 except a brass head instead of a nickel plated head, General Pump will not warranty this pump. We have already had them refuse one pump that had a bad connecting rod. To General Pump there is no such thing as a TS2020B
I also looked over the electronic idle option that Kohlerengines.com, very neat, how do you activate it , flow switch?
Probably because everyone - including myself - hammered away at GP for years to bring something new to the industry in the way of higher pressures. Back then we always had more engine HP than we had pump PSI available. It is possible that since InterPump did not have anything that could satisfy the 18 HP range that GP increased the TS2021 rating to accommodate the situation.
All pump manufacturers have always seemed to rated their products very conservatively with the TS2021 being, to my knowledge, one of the few items in the industry that is rated higher than originally intended.
Will the TS2021 handle the extra pressure? Absolutely. It has been doing so for years so when asked is it over rated my opinion is no. If anything the InterPump spec. of 2900 is under rated.
Mr Homer, I would sure like to pick your brain for couple hours....lol
Wow, so your saying that all the internals are the exactly the same for the ts2021?

Which is the general's TSF2021 on the interpump chart?
Looks like they under rated the gpm's in the US market.
So how much does a US market TSF 2021 really output @1450 and 1750rpm?
Looks like interpump's W2030/T2535 might be the US market TSF2021.
You think that is the scenario?
