I Finally Decided It Was Time To Build A New Washer. Since we clean roofs and homes efficiently with my "softwash" system, My Main Concern With Our Productivity Is cleaning Concrete. With Some Advice From Everybody Here, I Am Going After More Gpm's. I Purchased A 24 Honda & General Tsf2021. I Am Going to Combine These With A Heavy Duty Gear Box. I Have 2 Main Washers Now, Cat 51g (4.8 @ 3000) & Cat 45g (4.5 @ 3500). These Are Great Washers And Do A Good Job on concrete With Our 20" Classic And 36" Maxima. I Feel With 8+gpm And 3600 Psi I Can Reduce Our Time On Concrete Even More. I Should Have It Built And Running In A Week Or Two. I Will Supply It With A 100 Gallon Tank And Float System. Does Anybody Run A Tsf2021 On A 24hp?????

You might be over doing the hp.
I have a 18 hp with the tsf2021 which gives me 5.2 gpm @ 3500 psi. Given the ratio to achieve 3600 psi @ 8 gpm you may be right on. I'm no hydronic engineer either.

I Did Some Research On This Pump And To Max Its Pressure (3600) And Gpms (8.5), The 24hp Was The "Honest" Minimun. I Talked To Several Companies That Build These And They Recomended The 24 On A Belt Set-up. I Will Actually Lose A Little Gpm (.5) With The Gear Box Due To Its Ratio (2.2), BUT I Will Be Happy To Run Off A Fuel Tank Of My Choice Instead Of Fueling Every 2.5 Hrs With My 13's. Have You Had Any Issues With Your Pump?

You should probably also consider a much larger water reserve especially if this rig is for flat work. With that gpm I'd want 500 gallons+. If its strictly residential flatwork you may be fine with 250.

I HAVE HEARD THIS FROM SEVERAL PEOPLE IN OTHER TOWNS. I HAVE NEVER RAN A P/W WITH THAT KIND OF FLOW, BUT WE HAVE EXCELLENT WATER FLOW IN TALLAHASSEE. I RUN A 4.8 GPM WASHER AND SOFTWASH PUMP (6-8 GPM) OFF MOST OF OUR RESIDENTIAL ACCOUNTS. WE USE TWO 3/4" SUPPLY HOSES OFF THE HOUSE DIRECTLY TO EACH UNIT. HOMES ON A WELL SYSTEM WE MAKE OTHER ARRANGEMENTS (RUN ONE PUMP AT A TIME). I AM PUTTING THIS ON AN ALUMINUM TRAILER I JUST PURCHASED. I WORK WITH A 1OO GAL & 50 GAL TANK ON MY FLATBED RIG. I AM RIGGING THIS TRAILER WITH 3-100 GAL SUMP PCO TANKS. 1 FOR WATER WITH TWO HUDSON FLOATS, 1 FOR CHEM & 1 FOR MIX. IF I NEEDED ALOT OF WATER FOR A SPECIFIC JOB THEY WILL BE SET UP TO SUPPLY EACH OTHER.

2 feeds to tank
I never thought of running 2 hoses to the tank. I have a power washing business that specializes in hog confinement cleaning (hold jokes please, crappy work, I know) I have an enclosed trailer with a 625 gallon tank. When running 2 washers a 4x4000 and 3x3200 and filling off 1 hose it drains pretty quick, like 3 hrs quick. now these two hoses come off seperate outside hydrantes I take it? And has anybody ran a bypass to the tank to bypass the float valve? For setup filling. Thank you.

Thank you for clarifying. When things slow down I will add at least a bypass with a valve for the float. Hopefully that will put us at more like 4 hrs between filling. A break at that point isn't a terrible thing either. Thanks again.
Almost There
I Put The Motor Together Today (24 Honda). I Attached The Gear Box And Pump. I Also Installed A Tiny Tach And Top Mount Muffler. I Bolted It Down To An Old S/s Frame That I Will Mount To My Trailer With Rubber Feet. I Had To Put The Unloader On It And A Temporary Water Intake Just To Here It Run. It Fired Off On The The Second Try And Ran Smooth And Surprisingly Quiet Compared To My 13's. It Didn't Take Long For It To Turn It's Supply Hose Flat As A Pancake. My Well Will Only Put Out About 6gpm, So Without The Tank Assistance It Was Getting Thirsty. I Talked To A General Pump Rep Yesterday And He Said I Might Get 7.8 To 8gpm And Up To 3200psi With The Gear Box And 24 Honda. I Purchased A Gpm Flow Meter And A Couple More Gauges To Run Some Tests Of My Own.

WITH BATTERY, FUEL TANK AND EVERYTHING ELSE I AM JUST OVER $2500. THAT'S ONE GOOD GUESS, I COULD BUY IT (WITH OUT GEAR BOX) FOR $2900 + TAX & SHIPPING. I JUST WANTED TO BUILD IT MYSELF, I ENJOY BUILDING MY OWN SET-UPS. I WILL HAVE A BUNCH MORE IN THIS TRAILER. IT WILL HAVE 3 TANKS, 4 HOSE REELS, A SOFTWASH PUMP, GENERATOR, BLOWER, TOOL BOX, LADDER RACK, RACK FOR SURFACE CLEANER (36") AND MORE.

That pump alone is bigger than his whole head. Great setup.

Actually, that is not exactly true. GP specifies that required horse power to achieve max ratings for TSF2021 (8.5GPM @3600PSI respectively) requires 21BHP. Keep in mind that this figure is valid only if it's driven by an electric motor. Unlike electric motor, gas engines do not provide constant torque over their RPM range. Consequently, it will take more gas horse power turn TSF2021 at 1750 rpm (necessary to obtain 8.5GPM) while maintaining the rated pressure of 3600PSI. To put it in simple terms, you need a gas engine having 28HP.
However, that does not mean you can't achieve max pressure of 3600PSI or the max flow of 8.5GPM with 24HP engine - you just can't achieve them simultaneously. For example, 8.5GPM is possible if you match your nozzles such that the discharge pressure is 3100PSI. Max discharge of 3600PSI is possible with proper nozzle(s), however, you max flow will only be 7.3GPM.
With the example provided in this post, 3200PSI and 8GPM is right in between...although a belt-driven system would result in somewhat higher efficiency, and would yield an extra 0.25 on the flow compared to that of a gearbox.
Hope this info helps.

Tim I run two of these mine are belt drive. The honda works perfect. I have used the gearbox set up and it seems to have more a$$ behind it. I have not tested the pressure or gpm but the classic wants to fly in the air I needed a 5 pound weight to hold it down. Bob at PT says the belts are better due to less heat transfer. But gear oil can handle high temps so I am not sure which is better.
