CBR900RR Fireblade Turbo
Fuel-Injected, Two Computers, Intercooled, 360hp
360 HP! Not a 200 HP hodgepodge blow-thru carburetted piece of shit! There is no point turbocharging your CBR if it can't make more hp than anything on the planet (except one of our 500hp ZX-11's). RB Racing only builds sophisticated state of the art systems that feature: digital electronics, intercoolers, oil scavenge systems, air-by-pass and turbo blow-off valves, pneumatic billet diaphragm wastegates, dial-a-boost controls, ceramic coated custom designed turbos, stainless feed and scavenge lines; custom throttle bodies w/2 injectors per port; sophisticated idle air control system; closed-loop operation; IBM PC programmability; large volume plenums w/equal air distribution; digital Air/Fuel Ratio meters; sensors for air temp, engine temp, throttle position, manifold pressure, IAC, O2 Lambda, altitude compensation; and 600 HP fuel pumps.
These kits are docile enough for daily commuting, short-hop usage, reliable enough for long trips and are controllable enough to be road raced. All EFI components are water, corrosion and vibration proof with 1,000,000 miles of testing and 10 years of development. All systems are capable of achieving 360 HP. We recommend a maximum of 12 psi on Pump Gas (92 octane). For 12-30 psi we recommend race gas and water injection. All RB RSR fuel injections are compatible with stock and after market ignition systems. Contact RB Racing for specific recommendations relating to lockup clutches, connecting rods, pistons, water injection, compression ratios and ignition requirements.
All components fit under the fairing. There are a few minor mods but cornering clearance is unaffected. There is a lot more to turbocharging than being a plumber and routing some tubes and hanging a turbo on your bike. There are thermal and air flow engineering considerations. Most often, poorly designed systems simply try to overcome their design limitations by running more boost then blowing up. RB Racing gives you the benefit of 25 years of design experience so you can make the maximum reliable power from a balanced well engineered system. Six of our customers have gone into the prestigious 200 MPH Bonneville/El Mirage 200 MPH Clubs with 100 percent reliability, with over 1000 miles of actual competition at 190-220 mph, running 18-24 psi with zero engine problems (Harley, BMW, Kawasaki,Suzuki, Honda, Triumph).
We have been doing fuel injected, inter cooled turbos since 1985 and ALL RB Racing turbo systems have been fuel injected since 1989. People have attempted to duplicate our earlier draw-thru and blow-thru carbureted designs but they have not set one record. RB Racing remains the only turbocharger specialist that manufactures its own closed-loop IBM PC programmable EFI system designed especially for motorcycles, and the only manufacturer that produces its own custom throttle bodies for each application. There can be no compromise.
Fuel Injectors/Fuel Control: Your RB Racing CBR900 turbo kit is shipped with a dual strategy fuel control system using two computers. The RSR 800i ECU is connected to an 8 injector wiring harness. Four of these injector leads are connected to your primary (upper fuel rail) injectors which are 17 lb./hr which is sufficient to control your idling and full power requirements to 0" Hg. Four of the injector harness leads remain unconnected. The (4) 17 lb./hr injectors are programmed from 15" Hg to 0" Hg with your RSR ECU using a 1 Bar Map Sensor. This gives you extreme control of your normal driving in a programmable 16 x 16 matrix in your RSR ECU Autocal software.
A secondary fuel computer, an RSR AIC 400 controls the four secondary (lower fuel rail) injectors which are 34 lb.hr which covers the engine's fuel requirements from transition into boost to 30 psi. The RSR AIC 400 has four selectable maps (lean to rich) and a plus or minus 10% trim knob. The four maps and the trim knob can be changed manually without the use of a PC. The RSR AIC 400 has its own four injector wiring harness and 3 Bar MAP sensor.
If you wish to initially or, at a later date, you can use the RSR 800i ECU to control all 8 injectors and remove the AIC 400. If you elect to run 8 injectors configured as primary/secondary under control of the RSR 800i ECU the injectors MUST be the same size. For 360 Hp at a BSFC of .45 lb./hp/hr you would use eight 25 lb./hr injectors.
Mechanical Considerations: Modern (1987 up) 4 valve/5 valve combustion chambers are generally not prone to detonation for brief excursions to 12 psi. Do not confuse boost psi with airflow in CFM. Turbo nozzle discharge @ 12 psi from a small turbo IS NOT the same as 12 psi from a larger turbo. RB Racing supplies only large CFM turbos that will produce more power at a given level of boost than will less efficient turbos without custom designed compressors. Your modern 16/20 valve engine is designed to breathe in the narrow window of 10,000+ rpm and, as such the effective compression ratio is less than the stated 11.0 to 12.0:1 manufacturer's static compression ratio. When you factor in camshaft duration necessary to allow sufficient inlet/exhaust overlap @ 10,000+ rpm your effective compression is much less. On (1987 up) motors we normally recommend you leave the stock compression/pistons in place. If you are hell-bent on "building" your turbo motor do not lower your static compression ratio below 10.0:1. For camshafts you can increase the valve lift but do not shorten the duration and therefore the overlap of the camshafts. Overlap on a turbo motor prevents overworking the exhaust valve by allowing cooling of the valve to take place which also helps to prevent the onset of detonation. In general the lower the compression ratio the more boost you can run and the more power you can make. If you build a 50 psi. 6.5:1 C.R> motor it will produce a lot of power but be a "dog" everywhere below this. Early (1979-1986) 2 valve motors and motors with less efficient 4 valve chambers probably need 8.0:1 compression ratios to survive. For your Honda we recommend you retain your stock connecting rods and pistons if you are going to run 180-225hp. For 25 psi blasts to 300+ horsepower we suggest forged pistons and Carrillo connecting rods. We refrain from recommending pistons. To achieve 360 hp on a Dyno you are going to best be served by augmenting your motor with Nitrous Oxide for two reasons: (1) The intercooler will be ineffective on a static dyno as no fan will simulate 200 mph airflow. (2) The NO2 will cool the inlet charge and provide a brief power boost. Normally we don't recommend the NO2 due to it's vagaries related to temperature/pressure etc. , but in the case of Dyno Heroes it's a necessary evil. Hit the "Squeeze" at your own peril!
Lock Up Clutch: Without this your clutch will slip pass 200 hp...Mandatory on high output turbo bikes.
Ignition: Leave stock item in place. Since you are hell bent on fooling with timing we will ask you one question..."What is your pressure/crank angle" at your new, guessed-at settings. Ignition is a difficult thing to evaluate. Bad designs use retarded ignition timing to prevent detonation . Retarded ignition brings its own can of thermal problems. Proceed at your own risk.

Terms & Conditions: Contact RB Racing for availability and current terms for payment. Turbo systems are not on the shelf items, are very complex and are treated as custom orders. Custom orders are sold on an "as is" nonrefundable, nonreturnable basis. If for any reason you cancel your order prior to delivery or refuse delivery you are liable for the full amount including the shipping charges. It is not RB Racings responsibility to sell or dispose of custom orders which have been cancelled or refused.
Warranty: None. All parts are thoroughly checked prior to shipment. Due to the varying skills of the installers and the potential for abuse no warranties or guarantees are offered. If you have any questions call RB Racing before you beat the parts into submission with a large hammer...and never put your turbo or oil lines near a shop grinder or you will destroy your turbo instantly.
Returns: We won't accept them. These are one way custom items.
Technical Support. We do not have an open ended technical support policy to account for your inability to follow instructions, configure your computer or think logically. The parts are logical in their assembly. Detailed start up instructions are provided. Tuning and software tutorials are included in the Professional Software package. Approximately 40 pages of documentation and instruction come with the kit. We accept a limited number of tech support calls not to exceed a total of one hour. Beyond this we offer support on a prepaid retainer basis. Call RB Racing for details.
