R&D Powershot Adjustable Fuel Tuner No more Boost Limiter! R&D Performance Products, U.S.A. Announces the release of the new R&D Powershot Fuel Injection/Engine Tuning module for the YAMAHA GP1800. The R&D Powershot will deliver increased acceleration, stronger mid-range, and increased top speed performance by delivering a higher performing air to fuel ratio (A.F.R.) and allowing higher mass air/boost pressure levels to be utilized. R&D Performance has data logged and analyzed the O.E.M. Fuel map and Fly By Wire functions on the new YAMAHA GP1800 four stroke engine.

R&D has determined that one of the main horsepower and performance holdbacks in Yamaha’s Fly by Wire E.C.U. System is the mass air or boost limitation that is controlled by the Fly by Wire Throttle System. The Yamaha E.C.U. Manipulates and controls the mass air or boost pressure levels by closing the throttle plate which limits peak horsepower performance. The R&D Powershot interfaces with the E.C.U., fuel injectors, and sensors to unlock, take over, and control mass air or boost limitations. The R&D Powershot will allow the R&D C1 and C3 Monster Supercharger Wheels to perform to their full potential by defending against unwanted codes and internal E.C.U. The R&D Powershot comes pre-programmed and coded to safely alter the fuel map, intercept and recondition sensor voltage signals allowing up to 10 P.S.I.

The “Race Fin” has proven to outperform all other sponson kits on the VXR! Race Proven in closed course with multiple wins in regional and World Finals competition, as well as Dominating and winning the 2018 Mark Hahn 300 on the 85+ MPH R&D Turbo Machine of Mike Klippenstein! # 122-01805 R&D Pro Comp. Cool Air Filter Kit The R&D GP 1800 SVHO Pro Comp “Straight Shot” Filter Kit design will work re-route and straighten the airflow path to the supercharger giving the airflow path reduced restrictions. The GP 1800 has a noticeable amount of room and distance between the supercharger and the fuel tank over previous Yamaha models. “That said” R&D jumped at the chance to get to work and create a NEW DESIGN filter kit specifically for the GP 1800.

The R&D GP 1800 Kit gets rid of the traditional 90 degree turns, as well as re-positions the filter mount to offer the “Straightest Shot” possible to supercharger. The new design will install quickly with zero modifications, and complies with the 2017 stock class rules! The kit delivers a noticeable increase in throttle response, more mid range pulling power, as well as increased RPM’s! The R&D Filter installs easily in 15 minutes, and can be quickly removed in 1 minute for those pesky clutch change outs!

Pt # 200-01807 R&D Power Plenum Flame Arrester The R&D High Flow Filter design replaces the restrictive stock filter inside the OEM air box. This is the only performance filter that utilizes the water resistant OEM air box, allowing improved air flow. Because replacing the OEM paper filter element with the R&D high flow filter allows more air flow which equals more power and improved performance. The washable and reusable design means this will be the last filter you will ever have to buy. # 200-01800 R&D Surge Protector Kit The R&D Yamaha GP1800 Surge Protector Kit will significantly improve supercharger clutch and compressor wheel performance and reliability by eliminating damaging compressor surge.

Compressor surge is defined as the negative charge of pressure that causes turbulence in the supercharger that occurs during aggressive deceleration or off-throttle operations. When the throttle valve is abruptly closed at high rpm’s the engine decelerates quickly down from 8,000 rpm’s, however the supercharger is compressing air (creating boost) as the supercharger has to decelerate from 80,000 rpm’s. This turbulence is the primary cause of undue stress on the supercharger compressor wheel, intercooler, clutch system, and its components. The R&D Yamaha GP1800 Surge Protection Kit utilizes an automotive vacuum assisted Bosch pressure blow off valve that releases the unwanted intake pressure between the throttle valve and the supercharger thus keeping the pressures in P1 and P2 equal. As soon as the throttle valve is opened, the blow off valve immediately closes and the compressor can supply its full boost potentials to the engine. The R&D surge hose is manufactured from high performance, high-temperature silicone with an integrated molded riser for the blow off valve to function without hindering intake flow or velocity.

The R&D kit installs easily in place of the OEM rubber elbow joint with no modifications. The R&D Pressure Port installs between the MAP sensor and the MAP sensor bracket with a “bolt on” part.

The R&D Surge Protection Kit is a necessary and cost effective upgrade for the Yamaha GP1800 supercharged engine. The R&D kit comes completely assembled with silicone elbow, blow off valve, R&D B.O.V. Filter, mounting hardware and instructions. # 612-18008 Valve Only BOV Kit Kit Installed R&D 50mm Blow off Valve Kit The R&D Surge Protection Kit is an absolute must have part for the SVHO Yamaha supercharger which has a fair amount of off throttle surge even in box stock form. The new 50mm R&D Valve with its huge 50mm lightweight billet aluminum piston, and massive pressure relief ports will outperform smaller (25-35mm) HKS Sequential, and 35mm Greddy RZ Valves on the Yamaha SVHO Platform. The trick R&D has found with this valve is, in aggressive off throttle situations with a gear driven supercharger, the huge 50mm piston responds very quickly to allow the rapid reduction of boost pressure and surge which relieves back pressure and stress to the clutch. If you are running Boost Wheels that produce over 10 pounds of boost, R&D strongly suggests using this 50mm valve setup.

It only stands to reason that with higher boost pressures, a larger valve can allow quicker discharge of back pressure, surge, and mass air volume. Valve kit comes complete with R&D high temp silicone hose, 50mm valve, billet Aluminum V-clamp, and ¼” banjo style vacuum fitting. Aggressive throttle response, increased horsepower from solid valve seal. Improved valve action with larger diaphragm and variable spring control. Improved clutch performance from reduced off throttle back pressure and surge.

#612-18010 R&D 50mm BOV kit w/silicone hose R&D Water-Cooled Supercharger System R&D offers an industry first Water-Cooled Supercharger Housing System for the Yamaha SV Supercharger. The R&D SV Water-Cooled Supercharger Housing System is fully water jacketed to substantially reduce supercharger heat which will promote super stable and consistent horsepower. Heat is a derivative of super compressed air (boost). The more boost pressure, the hotter the supercharger gets while doing its work. One of the main keys in producing more horsepower and maximizing performance is managing heat. The R&D Housing will drastically drop the supercharger temperature a full 200 degrees!

The R&D compressor housing design also incorporates a built-in Anti-Surge Port, a very important feature desperately needed on the SV Supercharger! The R&D Housing Kit installs in place of the OEM inducer housing and mounts directly to the OEM Supercharger body. R&D Water Cooled Housing Kits assembled with R&D’s “High Boost” Billet Monster Wheels have dominated in Hydro-drag competition setting quick ET and top speed records. No other package of housing/wheel parts combination puts out more horsepower than the R&D line! The R&D water jacketed housing features a High Performance Volute (intake air path), Internal Anti-Surge Port, 100% Water-Cooling and a custom R&D Power Plenum Air Filter that installs directly to the supercharger housing which will eliminate air restriction like no other filter setup can. System installs in 45 minutes and comes complete with all necessary hardware and pictorial instructions.

The R&D SV Housing assembles and works with O.E.M. Stock SV Yamaha wheels or any SV Series R&D Monster Wheel Kit! Performance Benefits: Overall supercharger temperatures are reduced a full 200° F which will promote significantly cooler and denser intake air charges, improved supercharger clutch and compressor wheel life with the built-in internal Anti-Surge Port, increased RPM’s (up to 200 rpm), increased boost pressures, and improved top speed performance.

Fitment: The R&D SV Series Water-Cooled Housing Kit fits all 2014 and up SVHO Yamaha superchargers and works with all R&D SV Series Monster Wheel Kits. Pt # 612-24002 Dyno Chart See Yellow Line for C3 R&D SV-C3 Monster Charger Wheel The SV-C3 Monster Wheel Kit has been developed specifically for the Yamaha SV Supercharger using R&D’s popular and overall best selling C3 wheel design as a base platform. The SV- C3 will deliver noticeable pulling power with great throttle response, improved low to mid range acceleration, and increased overall top end performance over the stock SV wheel. The popular R&D C3 Monster Wheel replaces the stock wheels lower performing 7 blade design with a modern, more efficient, and more aggressive 11 blade design. The SV-C3 also follows the R&D tradition of a large and more aggressive exducer profile. The R&D SV-C3 Monster Wheel Kit will deliver 13-14 pounds of boost pressure at 8450. The SV-C3 will have noticeably better idle and super smooth surge free performance over the stock SV wheel!

The third bearing assembly adds a tremendous amount of shaft support which will keep the shaft in line and free from the stresses of “gear climb”. The third bearing assembly will also relieve stresses on the chargers main thrust system.

For Periodic clutch maintenance and adjustments, R&D has made it easy. The clutch slip can be adjusted easily, and clutch discs inspected and or changed out without removing the shaft from the supercharger with the special tool kit provided with each system. Minor machine work is required to the rear of the supercharger housing in order to achieve proper drive gear alignment (mating to the jack gear) and to true up the back cast surface so the third bearing housing cover mounts precision and true to the shaft centerline position. Machining is available from R&D (2-3 day turnaround time), or your local machine shop can follow the kit supplied blue print. Technology and performance make the Superclutch the finest and most effective clutch system available.

Superchargers vulnerable thrust bearing and main shaft bearing assemblies.

Stock Class and Modified closed course and endurance competition engines with superchargers set up and running higher boost pressures and higher rpm frequencies will eventually need thrust bearing servicing. As RPM levels and boost pressures are increased over stock, also the thrust load is increased on the thrust bearing system. When the main bearings in the supercharger wear over time, the shaft to bearing tolerance or clearances will become loose and the risk of friction burning or galling the thrust bearing assembly can occur. Servicing the supercharger main bearings periodically or upgrading to R&D’s new “High Performance Thrust Plate System” will extend the life of the superchargers thrust bearing significantly. When supercharger thrust bearing failures have occurred in the past, there has not been a repair option due to no replacement parts being manufactured or offered. This has led the team of engineers at R&D to go to work to offer not only replacement parts that allow the superchargers to be repaired, but a group of parts that work together to offer improved thrust bearing clearances and oiling over stock.

R&D offers both High Grade replacement shaft bearing kits and Main Thrust Bearing Kits that will work in any Yamaha supercharger. R&D also offers complete thrust bearing rebuild kits for stock superchargers running C1 Monster Wheel Kits and all supercharger wheel kits using the stock exducer size. R&D also offers rebuild kits for all C3, C5, C7 Monster Wheel Kits with larger exducers. Keep your supercharger serviced periodically or upgraded with High Performance Race parts only available from R&D. # 612-25025 OEM Replacement Bearing Kit (stock/limited class legal) Pt. # 612-25028 Supercharger Rebuild Kit with OEM Exducer/Thrust Bearing Assembly Kit Pt. # 612-25030 Supercharger Rebuild Kit with C3/C5 Exducer/Thrust Bearing Assembly Kit Installed R&D INTAKE MANIFOLD RIBBON DELETE KIT The R&D Intake Manifold Ribbon Delete Kit was developed to increase airflow into and through the intake system by relieving restriction.

Microsoft Works 4.5 Update

The R&D Intake Manifold Sleeve replaces the OEM intake ribbon producing a 40 CFM increase in air flow. The R&D billet sleeve mounts between the intake manifold and the throttle body creating a superior Venturi effect.

The R&D Intake Kit will add low end and mid range throttle response, and a full 100 plus rpms to top end performance to a stock SVHO. The R&D Intake sleeve is an absolute must have part to remove intake restrictions before contemplating power adding compressor booster wheels or turbo charger kits to the Yamaha SVHO engine. True horsepower gains on the Yamaha start right here with the R&D Intake Sleeve. More airflow will equal more power.

Note: The Kit comes complete with install jig to cut out the oem ribbon which is molded into the plastic manifold. A 2.750” hole saw (required) is sold separately or available at your local hardware store. # 612-17996 R&D Pro Series Intercooler Kit The R&D Yamaha GP1800 Pro Series Intercooler Kit was developed to directly replace the super restrictive and inadequate (for high performance use) O.E.M.

SV intercooler core. The SV Series Yamaha Supercharger is much larger than previous years and has the potential to pump substantially more volume and 3 times the boost of the older GP1800 supercharger (in stock form). However, Yamaha only minimally increased the core size and cooling capabilities of the SV intercooler (it’s not even close to being big enough). R&D’s intercooler design is more than double in area/size to eliminate the backpressure and surge, and allows the SV Supercharger to live up to it’s hyped up potential!

The R&D Intercooler offers high performance affordable inter cooling that will bolt directly into the OEM stock location utilizing the OEM inlet cover, and all stock hoses and hardware. The R&D SV Pro Series Intercooler Kit is constructed from aircraft aluminum and is extremely easy to install, removes quick for cleaning and winter storage, is ultra strong, and rubber mounted so vibration will not compromise the long term performance. This R&D SV Intercooler has been tested against every manufacturer’s current intercooler designs and has proven to out flow, out cool, and out power them all. The R&D intercooler offers better cooling efficiency through its “made in the USA” aluminum core design that easily out performs cheaper inefficient intercooler cores known to crack, leak and cause extreme detonation. The R&D SV Pro Series intercooler core Kit will flow more air, deliver better cooling efficiency, and allow the stock SV and all R&D Monster Wheels to live up to their advertised airflow volume and power potential.

Tested to easily flow 18-20 PSI of boost @ 90-100 degree air temp, the new R&D SV Pro Series intercooler design drastically reduces the SV’s deadhead air restriction (Backpressure) producing ultra responsive “POWER NOW” acceleration all the way through the RPM range. Significantly improves intake air cooling efficiency. Flows 60 CFM more than stock.

Bolts directly into stock location w/O.E.M. Hardware. Increases overall horsepower. Aggressive holeshot and mid range acceleration.

A Must Have for ALL R&D Monster compressor wheels. Retains O.E.M. Flushing system for maintenance Pt. # 612-18006 R&D Pro Series Racing Intercooler Kit The “All New” R&D Yamaha GP1800 Pro Series Racing Intercooler Kit was developed starting with a clean sheet of paper and several key factors in mind. We wanted to build an intercooler system that offered the easiest of installation, easiest to maintain, looks like an indy car part, keeps the air cooler than it looks, and most importantly, be non restrictive to allow maximum CFM airflow for maximum horsepower. The new R&D Pro Series Racing Intercooler Kit is constructed from aircraft aluminum and is extremely easy to install, removes quick for cleaning and winter storage, is ultra strong, and rubber mounted so vibration will not compromise the long term performance.

This new intercooler system has been tested against every manufacturer’s current intercooler designs, and has proven to out flow, out cool, and out perform them all. The R&D intercooler offers better cooling efficiency through its “made in the USA” aluminum core design that easily out performs cheaper inefficient intercooler cores known to crack, leak and cause extreme detonation. The R&D Pro Series intercooler core will flow more air, deliver better cooling efficiency, and allow C1-C24X Monster Wheels to live up to their airflow volume and power potential.

Tested to easily allow 30 PSI of boost @ 90-100 degree air temp, the new R&D Pro Series Racing Intercooler design drastically reduces deadhead air restriction producing ultra responsive “POWER NOW” acceleration all the way through the RPM range. All data and air temp was logged with a MoTeC M400 with i2 logging software. It should be noted that pressure data was taken in the plenum with the stock MAP sensor and backed up with a mechanical gauge. The R&D Pro Series Racing Intercooler Kit also has an incorporated integral flange which will allow the bolt on addition of an R&D/Tail Q Series 50mm Blow-off valve (Pt. # 613-95263 sold seperately) which superbly regulates compressor surge or blow-off under deceleration.

Significantly improves cooling efficiency. Flows 90-100 CFM more than stock (allows 60 pounds of unrestricted air). Bolts directly into stock air box location w/O.E.M. Studs and rubber grommet hardware.

Increases overall horsepower (core size/area allows up to 600 horsepower). Aggressive holeshot and mid range acceleration.

Works great with any R&D Monster compressor wheels. Retains O.E.M. Flushing system for maintenance. I.J.S.B.A. Limited Class and Pro Open Legal Pt. # 612-+ R&D Multi-Pressure Port Boost Gauge/Surge/RRFPR Adaptor Kit The R&D Yamaha GP1800 Multi-Pressure Port Adaptor Kit will allow quick and easy hook up of a manual boost gauge, surge valve, and a raising rate fuel pressure regulator. The R&D Pressure Port Adaptor installs in the MAP sensor hose and has 3 ports that allow for the operation of a vacuum/boost gauge, check plenum air temperatures, operate a surge protection valve, and operate a boost referenced fuel pressure regulator (RRFRP), or any three of these applications at the same time with one simple part.

The R&D Pressure Port Adaptor Kit comes complete with 12” of vacuum hose, multi-line fitting, 2 tube covers, nylon cable ties and instructions. # 612-92006 The R&D Supercharger Block-off Plate The R&D Supercharger Block-off Plate is designed to seal the case on the front of the engine that is exposed when the supercharger is removed for a Turbo. # 612-19100 R&D Racing Adjustable Cam Gear Kit R&D’s Racing Cam Gear kit allows a huge boost in overall horsepower to be gained by custom tuning the Camshafts LSA (lobe separation angle) set up. Tuning the Cam’s LSA with R&D Racing Cam Gears will add a significant jolt in low end acceleration power, increased mid range performance, and add 2-3 MPH to your existing engine package. Adjusting the camshafts LSA is a very simple “BOLT IN” modification with the R&D Cam Gear Kit. Understanding the LSA concept principle is fairly easy. A wide LSA like found in the GP1800 will generally result in decreased valve overlap, later intake events, earlier exhaust events, and high intake manifold VACUUM (higher vacuum at idle) which produce great idle, smooth accelerating with mild low and top end power.

Wide LSA’s are great for school buses and soccer mom vans. However, if strong mid range pull and top end horsepower is what you’re looking for, then a significantly narrower LSA will need to be generated.

The R&D Racing Cam Gear Kit allows the LSA (lobe separation angle) to be adjusted much narrower which will generate increased valve overlap, earlier intake events, and later exhaust events. Resulting in snappier throttle response, increased mid range and top end power with more boost. The R&D Racing Cam Gears are billet CNC machined, Heat Treated, and ground from steel alloy to deliver durable strength with precise timing. The R&D Racing Cam Gear Kit offers 25 possible advanced LSA combinations that allow the cams to be precision tuned depending on the type camshaft lift and duration package, type of racing and type of fuel. The R&D Cam Gear Kit utilizes the proven and precision O.E.M. Shouldered bolt mount design to perfectly center, align, and time the cam and properly support the cast cam flanges from cracking and breaking over slotted or inserted type gears that are known to break cam flanges.

R&D knows that cam lobe profile and cam timing is the heart of a good running engine, In fact, R&D has built a specific engine designated for degreeing, checking and proving camshaft lobe specifications, LSA and LC combinations. Depend on the Pro’s at R&D to deliver all your horsepower needs.
