I HAVE 115 DYNOS IN 28 STATES NOW SO WE HAVE A LOT OF EXPERIENCE!
THIS IS A PATENTED PRODUCT BY STAN HEWITT
THE COMMON DYNOS & OPTIONS WE HAVE AVAILABLE AT HEWITT INERTIA DYNOS ARE NUMBERED BELOW.
**NOTE THAT ALL DYNOS CAN BE UPDATEDOR CUSTOM BUILT OR UPDATED TO LARGER FLYWHEELS AND SEVERAL DATA SYSTEM OR OTHER OPTIONS! ALL QUOTES WILL BE E-MAILED (PDF FORM) AND/OR FAXED DIRECTLY TO YOU SO YOU KNOW EXACTLY WHAT YOU’RE COST IS, INCLUDING FREIGHT! (I WILL NEED YOUR ZIP CODE FOR FREIGHT ESTIMATES)? WE HAVE JUST SWITCHED TO A LARGE GROUP OF FREIGHT SHIPPERS! Very few can beat our prices on flywheel or dyno shipments!
PRICES SUBJECT TO CHANGE!
**ALL DYNOS CAN BE MODIFIELD & CUSTOMIZED TO FIT YOU’RE NEEDS. WE HAVE BUILT DYNOS FOR QUARTER MIDGET RACERS WITH 6 TO 1 GEAR BOXES AND ELECTRIC START FOR GOLF CARTS WITH CLOCKWISE & COUNTERSLOCKWISE ENGINES(dual starters systems, CW/CCW).
WE ARE ALSO WORKING ON AN ELECTRIC CLUTCH DYNO. WE CAN ALSO HELP YOU WITH A BASIC DYNO ROOM IF YOU HAVE QUESTIONS.
We are very interested in building any type of custom dynos, which includes, harleys, cars or trucks, chassis dynos, any type of engine!!!!!!!!!!!
(1) STARTER RELAY UPDATE KIT-($43.87) this is for customers that have my dyno with electric start and wish to update or customers that are putting electric start on their dynos. It includes a wiring harness with (2) relays, a heavy duty fuse link with 30 amp fuse. We’ve found out the solenoid is not getting enough amps when we have a 25 to 30 foot of wiring to the starter. This stops those false starts were solenoid doesn’t engage or were starter seems to crank real slow at first. We also recommend using 2 gauge battery cables. This combination increases cranking speeds by 20 to 25%!
(2) DIRECT DRIVE KIT TO REPLACE ONE-WAY SPRAG & TORSION SHOCK KIT-($106.24) –we have found out the one-way sprag disengages and engages at high engine rpm. By replacing it with a solid shaft and leaving the torsion shock bushing in, we have extremely repeatable results. Five dyno pulls with only 2/100ths of a horsepower difference in some cases.
(3) 1 ¼” ROUND TO 1 3/8”-6 SPLINE ADAPTER KIT ($165.24)-This converts 1 ¼” round shaft with ¼” keyway to one-way sprag clutch and then to a adapter to adapt it to another 1 ¼” shaft. Allows you to put a one-way sprag clutch between your flywheel and your main dyno axle.
(4) 2009 QUARTER MIDGET CLUTCH DYNO OPTION- ESTIMATED COST $605.47-Allows a person to dyno HONDA, WORLD FORMULA, DECO CONTINETIAL 6 to1 gear box engines just like a standard engine- measure torque, horsepower, acceleration, air/fuel ratio, any options you order on data system. I have not put this on a Briggs 6 to 1 (Sun Gear) but it will be possible?
(5) We do make an electric start, belt drive Quarter Midget Dyno (with or without one-way sprag clutch) that dyno off the end of the crankshafts of Honda 6 to 1 gear box motors. This is a “Pro” version dyno, more for the Professional engine builders. I’m not sure this will work on Deco-Continental or Briggs.
(6) 2008 ELECTRIC START COMPLETE KIT-($714.35)-We’ve made some changes, installed a relay kit so solenoid and starter engage better with more amps and installed 2 gauge battery cables. These two changes make starter system crank about 20 to 25% faster. This may help some of you that break belts on the Animal motors. Crank the engine up to a highest flywheel R.P.M., before opening throttle and letting up on ignition switch. This will minimize belt breakage. Also hold brakes down when killing engine, and don’t let up till flywheel rotation has stopped. The “NEW” 2008 belt system helps tremendously!
(7) “NEW” 2008 35MM BELT DRIVE-($999.99)-This comes with two Kevlar belts-This has a larger sprocket on the main dyno axle and a larger driver with more teeth engaged on the engine. This new belt system almost totally eliminates belt breakage, even on animals. We also have a slightly smaller sprocket for customers wanting to dyno very low horsepower engines. Call me with Questions? Replacement belts are about 40% off list price. If your doing a large quality of 2-cycle engines, tell me because we do have a different combination that works with both 2 & 4 cycle but is a little more expensive. Or we can do a jackshaft that will allow multiple gear ratios and combinations. This to is also a little more expensive to.
(8) DATA ACQUISITION SYSTEMS–wiring in shop must be grounded! We can offer a used original datamite system with premium flywheel sensor, complete wiring harness, up to date software with unlock code & license, one channel analog converter box with new 14mm head temp sensor, manual, power supply-$599.99. This will allow you to do S.A.E. weather correction manually. Or buy a USB to serial port adapter & weather modem and have it download thru USB port, ($175.00). I do have a few digital weather stations left for manual S.A.E. weather correction ($150.00) or can supply with modems ($175.00) to download to computer. The New Mini-USB Basic has been out which I did some testing on, works greats. I’ve sold several and zero problems. I sell it in a basic version with internal S.A.E. weather correction, dual temp with head and exhaust/liquid sensor, no engine rpm, so no clutch testing, with rare earth magnets, Pro software, new manual with newest updates, set-up and training over the phone. The above is what most customers want. Price is $1366.28. If you want something cheaper than this, call me, we can do a very basic system and then gradually add to it if that’s what you want? Next step up is Mini-USB PRO, same as what is listed except comes with engine RPM sensor and inductive pick-up box and wiring harness. Price is $1633.68. Next up is the USB III PRO-This includes everything that the USB MINI-PRO has except it has 4 long temp leads/channels for temperature, and 4 sensors, and more expansibility. The 4-cycle people can measure head temp, exhaust temp, engine oil temp, Air/Fuel Ratio all at one time on the computer screen and print out in report form and graph the data. You can also purchase a temp sensor so air temp can be measured as its going into carb. Price is $1735.65. Another option is Air/Fuel Ratio which is an optional price to, but can be measured thru this system. Remember with Pro Software, you can overlay up to six graphs at a time, click on any rpm increment and see hp & torque in 100ths of an increment. ZOOM in on any part of graph down to 30 rpm increments and compare up to 10 columns of data at a time in report form. Go for a wide screen LCD monitor or laptop. Add a color printer or all-in-one (move your old printer to the dyno & get an Epson 600/800 for the office?) and you’ll love it. Don’t forget all these systems can dyno clutches! See engagement RPM, see slippage ratio, see total lock-up of the clutch and again compare up to six graphs at a time! Gotta get the horsepower to the ground! Remember, if you send me your computer/Laptop, I’ll help you with all installation, set-up and training and answer all follow up questions. I train you in not only dynoing engines but how to dyno clutches correctly. You get all my phone numbers for any questions you might have or help with problems at any time. You can fax or e-mail printouts and we can discuss over the phone to make sure you understand al aspects of program?
(9) 14 OZ VIPER LUBE GREASE-($12.75) For Sprag clutch and Pillow Block bearings- grease pillow block bearings at slowest time of the year. This will cause your horsepower to drop slightly for a short time. This is synthetic grease so it is thin in viscosity and will not affect HP as much by low room temperature.
(10) ADD-ON ONE-WAY SPRAG KIT WITH TORSION SHOCK SYTEM-$717.31- This is an option for any of the following dynos. It comes standard with a 75 hp sprag clutch. There is a 100 hp sprag that can be used as any option (add$65.00). This kit is designed for 1¼” or 1 ½” shafts. Larger sizes will be slighter higher. This option allows a one-way sprag clutch to be added on dynos up to 100 hp. Horsepower’s above 100 hp, we’ll use a more expensive sprag clutch if you want one.
(11) 2009 ONE-WAY SPRAG KIT FOR 1 ¾” & 2” FLYWHEEL SHAFTS-$899.99-This is a heavy duty sprag kit for use with flywheels axles 1 ¾” & larger. Includes a 100 hp sprag clutch. Used for engines above 30 hp. This does include the standard torsion shock kit and it to can be updated to larger size if you want? Includes custom built shafts and adapters.
(12) 2009 DUAL ELECTRIC STARTER SYSTEM– $249.99- Adds a second starter system for use with large flywheels when trying to use a wide range of horsepower engines on very large flywheel.
(13) KIT DYNO USING ENGINE CLUTCH, 25 HP FLYWHEEL-$3199.99–You do all the mig welding. I recommend a 175 amp welder with .030” wire or larger. Many of the smaller parts are ready to assemble and many are already welded. This includes a completely assembled balanced flywheel assembly with every part to make a 36” x 36” engine/clutch dyno. You supply motor mount, and computer system, clutch (Premier Titan recommended with red or yellow springs), surge protector. Wiring in shop must be grounded. I do have some used digital weather stations for manual S.AE. weather correction. Used original data systems ( included) with one channel of head temperature, cost about $599.99, which includes premium axle sensor and new 14mm head temperature sensor. Will work on Windows 95 to Vista. Does include newest most up to date software. You can ship me your computer for complete installation of software and set-up and testing ($75.00). Or we can do over the phone which can take about two to three hours for installation and training. Call with zip code for freight estimate. Residential freight will cost $50.00 more. Best if you can find someone with forklift and loading dock.
(14) 2009 P.A.K. CLUTCH DYNO-$3499.99-This is a dyno were I weld the main frame up. Do all work on the flywheel, assemble, remove, computer balance and reinstall, install & tack weld brake bracket, tack weld motor mount rails, tack weld top flywheel cover. Tack weld control stand. You do all finish welding. I will help you with software installation & set-up. You get everything to build a complete clutch type dyno (you use a clutch on the engine to measure hp & tq.) You will need to supply motor mount & complete computer system. For high hp engines above 30 hp, see 40mm dyno.
(15) 2008 BASIC CLUTCH TYPE DYNO-($3922.68)-This is priced with a used data system. We can price with a new system if you want & pay difference. This price includes a 25 hp balanced flywheel with premium NTN Ultra-class pillow block bearings along with a heavy duty sprocket hub and #53 tooth sprockets so you can dyno clutches. It includes a 36” x 36” table with 1 ¼” stress-proof axle, motor mount rails, side panels and one end panel. Powder coated medium silver. If you do not want powder coating-deduct $135.00. You would need to supply international (wide) motor mount with wings, basic computer with color printer. Remember, if your computer crashes, you’ll pay me an hourly wage to reinstall and set-up software, so install new hard drill if it’s over 2 years old. The recommended clutch is a Premier Titan with yellow/red springs ($150.00). I can supply a complete computer system ($549.99 to $749.99) and install software and set-up and test. Optional 29 hp flywheel-add $113.00. This does include a small parts kit to make sure you have everything to get started. This dyno can be updated to electric start and belt drive? For applications above 30 hp, I’d recommend 1 ¾” stress-proof axle or larger (including axle bearings).
(16) 2008 ONE-WAY SPRAG CLUTCH DYNO-($4650.59) This is the same dyno as above #14 except with a large torsion shock bushing, (2) couplers, and a one-way sprag clutch assembly with axle adapter. If you hear an engine pulling down (forgot to put oil in it) like it’s about to lock up, you can let up on throttle and motor will stop and flywheel will coast till you hit the brake system. One-way sprag needs to be greased at least once a month. Sprag can be locked up (grade 8 or 9 bolt) so you can dyno clutches! This price will be with used original data system with head temp sensor. S.A.E. weather correction would be done manually. Again, you will have to talk to me about what data system and options you want. I always quote everything on paper and e-mail (pdf) or fax you the quote. You will need a Premier clutch with yellow/red springs, a motor mount, and a basic computer system with color printer. This does includes small parts kit to get you started. This dyno as a P.A.K. dyno ($4227.90). Call with questions? This will be made so electric start & belt drive can be added at a later date.
(17) 2009 25 H.P. FLYWHEEL WITH SPRAG, ELECTRIC START & NEW 35MM BELT DRIVE-($7026.17)-This is becoming the #2 seller for small engine builders! This dyno has standard a 25 hp flywheel, 2008 electric start, the new 2008 35mm belt drive and includes a one-way sprag clutch. This does include the New USB Basic data system. S.A.E. weather correction can be done by computer with new style data system. It also includes a small parts kit. This dyno is more for the serious engine builder. Optional larger flywheels’ can be installed for their additional price. You will be able to dyno clutches on this dyno with add on (add $200.00). I can supply a computer system (laptop or desktop, $550.00-$750.00) for you along with a printer ($79.99 & up). You will need a surge protector (10 outlet, $39.99) and wiring in shop must be grounded. You will need to supply an international motor mount and high amperage top post battery for electric start and need a 10 to 20 amp battery charger. If you do not want sprag clutch kit-deduct $727.00 from price. Then it will be direct drive, see #17.
(18) 2008 36” PRO DYNO WITH 25 HP FLYWHEEL,DIRECT DRIVE, ELECTRIC START, 35MM BELT DRIVE, 2008 USB PRO DATA SYSTEM –($6564.49)-#1 engine builder dyno!
