R1100S and RT and GS Turbo Systems

Poor R1100S, a lousy 86 rear wheel hp, and a tail-mounted, wannbee Ducati, license plate warming muffler. Twin plug, single plug, "Replica" paint, carbon fiber bits etc....All foo, foo, crap for a bike with no power. When they say it's not about the money...It's about the money. When you haven't got the power...It's still about the power.
RB Racing gives you a power correction with 240 hp worth of an intercooled, water injected turbo. For you incremental types, you can dial down the power to a manageable 135 hp and keep your fear factor in check. Hey, it's still got a shaft drive so you won't be running 220mph! We like to run way over 200 but not everyone does.

Front mounted Boost Master wastegate controlled by a handlebar mounted pneumatic boost controller. Dial up your courage. Ceramic coated merge collector turbo header has dual egt ports for our manadatory Orca Turbo Dash.

Charge cooler sheds heat and breaks up directional flow from turbocharger. Downstream are four injectors and two water injection nozzles. New electronics control the fuel and water injection.

No one is going to see the turbo as it's under the bike. All anyone will see is the end of your tail pipe anyway...Unless you just like to park and talk and bask in the glory of your new toy.
The Jig is Up!

This is most of the fixtures required to make a R11 Turbo kit. Actually there are about twice this many, not including the cnc maching setups that we use. Figure that we redesigned this kit six times from 1994 to present you could throw away about five piles of steel this large...not to mention barrels full of parts we sent to the scap heap. Don't ask how much money we spent because it is way too painful to think about.
Wannas

After doing this turbo stuff for over thirty years we have encountered all sorts of interesting people. People who contact us generally fall into three classifications...Wannaknows, Wannabes, and Wannabuys. The first two outnumber the last one by about 1000 to 1. Factor in the lost time we have spent in dealing the 999 and we could have been tooling down the Cote D'Azur in a new Ferrari, far, far, away from telephones and endless people either trying to pry information out of us, or just trying to satisfy their endless curiosity. In short, we only deal with the third category these days.
Raw Parts

Takes a lot of fixtures and sub fixtures to make this part accurately. Don't ask us to buy one as it is only sold with the kit. You don't want to know what it costs in final form factoring in shop time, wages and administrative matters like coating, laser cutting, welding supplies, employee training etc.
High Stakes

You're sitting at the Baccarat table in Wendover keeping your steely eyes on the Mormons who've sneaked over from Salt Lake to be naughty, and those Bonneville groupies who are eyeing your pile of chips see a good time coming. Push that pile of water jet cut copper gaskets out and bet the farm. It's your lucky night. That's $1,000.00 in copper turbo gaskets. It does get expensive.
More $1,000.00 Days

Customers just think we just stop whatever we are doing and go build them a turbo system for their R Bike. It doesn't work that way. Oil systems are particularly ornery and chew up months of development in prototyping and then even more time in the refinement and testing phases. At that point you get to take your sample parts to your hose fabricator and hand over a four digit pile of your hard earned dollars just so you can have some parts in stock. And there are a lot more parts in a turbo system.
Some More Parts

These are a few of the parts that are in a BMW R1100RT Turbo Kit. Just a few. Bending , fabrication, ceramic coating, cnc machining, laser cutting, and many hours of tig welding. Procedures, documentation, training....tens of thousands of dollars tied up so we can go fast. Of course, if you sit in a cubicle, and order parts from China for Walmart you have little appreciation for this.
R1100/1150 Intercooler

Well, you start with 20 pieces of aluminum. Cut, machine and otherwise make them into some specific shape. Then you start welding. You best keep cut patterns, sample parts and notes or you will not be able to duplicate it again. We make a prototype like the one below, test it over several thousand miles and if everything is OK we go into limited production. A lot of hours and quite expensive.

Gets complicated. Holes for injectors, holes for water injection, holes for injector hold downs. Cut, weld, debur, heliarc, machine, drill, tap...it never ends. We tested this prototype for several thousand miles.
Water Injection 1

Water injection is mandatory on all BMW turbocharger kits. We make an aluminum water reservoir that fits in the license plate location. Here it is trial fitted to a R1100RT and a R1100S prior to being hard anodized. A clear hose is used as a sight window to check water level. Capacity is slightly above one quart. On R1100/1150 turbo kits the water is injected into a common area, in the intercooler, between each inlet runner. Two water nozzles are used and are staged for low and high boost levels.. It is completely pre-planned and there are no adjustments to make. The RSR Pro-440 230 psi pump mounts on base of reservoir.
Water Injection 2

Hard anodized water injection reservoirs for our turbo kits. Lots of cutting, deburring, cleaning, welding, and machining to get these ready. Lathes, mills, heliarc, large buffers, drills, taps and employees. Money, money, money....Accountants cringe. The IRS doesn't believe you spend all that money on R&D until they audit you.

License plate mounted. Integral 230 psi pump assembly. Stainless steel hardware. Level sight window. Quick release stainless steel filler plug. Hard anodized for water and water alcohol or water methanol corrosion resistance. Whatever it takes. We know what it takes. Wannabes and Wannaknows whine endlessly. Wannabuys buy. Someone goes fast.

Dual stage water injection. Solenoids mounted on powder coated support bracket for BMW R1100/1150RT. Endless details for trouble free performance.

Dual stage water injection pressure switches. Primary nozzle activates at 4 psi and the secondary joins in at 8 psi when things get serious. R1100/1150RT beneath left panel. Relays for these are secreted into the oem fuse box. Switches only see boost, not vacuum/boost.
RSR AIC400 Additional Injector Controller

We preprogram the fuel curve for the two additional injectors with our RSR AIC400. About 2000 points to program. We do it for you.
Turbo Dash...Ultimate Instrumentation for the Turbo

Water injection activation is indicated on our Orca Turbo Dash. 30 L.E.D.s display 30" Hg to 30 psi of boost (3 Bar). Three digits display manifold pressure in Bar, 0.00 to 3.00. Two type K fast-acting thermocouples read exhaust gas temperature. Three buttons: high recall from memory; display dimming; and reset to clear memory. Two additional L.E.D.s indicate the two stage water injection system. Mandatory on all BMW turbo kits.
New Cloisonne LSR Labels

In line with the quality we put into all our products we have had made some Cloisonne (fired enamel) Labels made for our Black Hole Mufflers. Polished glass on nickel-plated brass, these are a very high quality jewel-like part. Turbos, speed, Bonneville....
Old Design

These are the main parts of the older R1100S kit...mentally assemble it if you will. It's now obsolete by four generations. One of several R1100S kits made for non-paying customers.
Old Design Inlet Plenum and Runners

Two additional injectors controled by our RSR AIC400 Additional Injector Controller. The brass fittings hold water injection nozzles for high boost operation. The mystery hole in the top shall remain a mystery. This was a second generation part.
New Bosch Billet Fuel Regulators

We have improved our fuel regulation system by using a Bosch Billet Adjustable Regulator. We use these in all our fuel system upgrades as well as with our turbocharger systems. More precise and better seats with a hardened and ground ball and socket design. Holds pressure better for smoother operation and more reliable low battery condition starting.
Part Number 06-1023 $195.00. Comes with 12mm x 1.5 jam nut for easy mounting.
R11...It all Starts at the Port (Two Bolt and Three Bolt)

Machined parts, laser cut parts and fabricated parts...all to smooth out the exhaust flow. We got rid of the "dead" high pressure, low velocity no-mans land and sent the exhaust gases on their way in a more professional manner.

The oem part features a severe "bump" as well as a nasty mig weld on the inside of the flange...we smoothed all of this out. Wait till you see the rest of the parts as well as the other innovations that you can go Ducati hunting with. We take all of this very serious...it's not about selling parts. It's about providing real gains for a bike that's damn sophisticated to start with.
Three Bolt (Early)

Early models dating from the R1100RS used three bolt flanges. We fabricate the precision port spigots for these that rest against a gasket in each round port. Later models went to the above mentioned two bolt design and dropped the spigot design. Weuse spigots to improve flow on both early and late models.
Unlike the earlier R bikes which featured three bolt flanges, these later models have a stainless steel sandwich gasket that surrounds the periphery of the port...our exhaust uses the oem gasket for sealing but adds the spigots to keep the port velocity high and to ease the transition into the 45mm primary tube.
LONG TIME AGO: TURBOS: 8 VALVES, TWO PISTONS, UNKNOWN TERRITORY
When you undertake a turbo project with a brand new bike, especially the first new boxer of the millenium, the R1100RS, chock full of expensive German parts housed in a vertically split crankcase, you get a little nervous with visions of broken rings, blown head gaskets and other terminal explosions. We really shouldn't have worried as BMW made this one tough puppy.
Heavy stainless steel header, 225hp turbo, new inlet plenum with two additional injectors controlled by an RSR AIC400 Additional Injector Controller, intercooler, RSR Air Fuel Ratio Gauge, a positive oil scavenge system, and a free flowing cannister muffler...throw in 400 hours of development and you have the fastest twin on the block.
Originally tested by Sport Rider Magazine's crew of Nick Ienatch, Jason Black and Lance Holtz the bike was put in a group of Ducatis, Moto Guzzis and the like for a four part comparison: road ride, drag race, top speed run and a road race on the Streets of Willow Springs Raceway. The R1100RS turbo outran all the Ducatis in the road race portion as well as the during the road ride. As for the top speed this was meaningless as the Motronic computer limited the top speed to 145mph. For our own amusement we cruised the bike around the Palmdale high desert at 140 mph under closed loop control. Detecting a certain lack of respect from the journalists who were seen bowing to carbon fiber bits from Italy we pulled the bike from the test...It did not belong in the company of inferior machinery. A man's gotta do what a man's gotta do. We struck a deal with Nick Ienatsch to do a separate small article which he, to his credit did. Maybe pictures of hero journalists in the afternoon sun dragging kneepads on Supemono Ducatis sells magazines but nobody rides them and they are suck ass slow compared to the R1100RS Turbo. Isn't life fun. Like the French say and know so well..."Everything is politics". Nick made a pass at the drag strip running a 10.6 second quarter mile at over 130mph with very low boost. Damn fast twin!
Subsequent tests were published by Joe Haile, famous for his series of Turbo books and by Paul Peczon aka "Uncle Paul", journalist and Dot Com warrior from Silicon Valley. These reviews are on the internet or hidden in your old piles of magazines. They were glowing in their praise. We regeared the bike and with the rear wheel running 178mph the bike went through the traps at 158mph at El Mirage. The SCTA officials at El Mirage thought the bike would kill all the Harleys so they ruled it's pushrod operated valvetrain to really be an overhead cam and moved it to another class. Like we said it's all politics. A boy named Sue, how do you do!
Uncle Paul now has a large family in the Bay Area here in California and has moved on from journalism to non dot-com activities that pay better. The turbo everyone tested went to some customer, an architect in Arizona. We're still waiting to get paid for it.
Reality Check
This may be your hobby but it is our business and in a business sense, turbos make little sense. That we choose to do them is our choice and it has nothing to do with money. The R&D and the tooling and the testing is money that you never get back...Never! Never! Never! No one appreciates what you do and almost no one understands what is involved. We have done enough free work and R&D to pay for a mansion in Beverly Hills. It is our choice. Got to love turbos if you want to play with them.
We get calls from people who want to know if the exhaust they have will work with the turbo (think about it). We have people who call and tell us they will be happy with 200hp all the time (?). We have people call and tell us they are coming by for an installation...they don't ask, they just announce it. We tell them no and they tell us we are assholes. Got to love turbos if you want to play with them.
We have worked with a number of customers on prototypes. Several have announced they were not going to pay us any money because "RB Racing" was going to get rich off the prototype. We offered any of these people to simply pay us for our time and parts and we'll let them have the business. For some reason they always decline the offer. Something about them getting their regular paycheck without any risk or investment. Got to love turbos if you want to play with them.
Over 600 BMW turbos and 1500 turbos for more than 25 platforms over the years. Thousands and thousands of man hours and hundreds of thousands of dollars invested. Computer code, flow benches, test equipment, custom software, electronic circuitry design, specialized castings, cnc and manual machinery, fixtures, specialized fabrication and welding equiment, training of employees etc etc. Got to love turbos if you want to play with them.
Be prepared. This is serious stuff. Know your responsibility. These aren't phony carbon fiber tank protectors.
