500 এইচপি! Not a 200 HP hodgepodge blow-thru carburetted piece of shit! There is no point turbocharging your ZX-11 if it can’t make more hp than anything on the planet. 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; এবং 600 HP fuel pumps.

Two ZX-11 Turbos protecting a 220 mph scooter headed for Maxton. Checker board floors always means the deal is serious. Probably not a good idea to try to peek at all the serious hardware hidden on the scooter. Rumor is that it has two turbos, a supercharger and is running on nitro. ভাল, if the scooter blows up or the government confiscates it, the two surly characters Bob and Jamie can always race the low tech ZX-11 Turbo pit bikes.

Cold air, asphalt and the clock. Cruising at 200 plus, chin on the tank, half a tank of race gas and no cops. Blues Brothers.

ফলাফল: after passing tech and qualifying runs for license, 202 mph @ 10 psi with some minor coolant leaks. পরবর্তী: Up the boost to 18 থেকে 20 psi and increase the speeds. Watch the movie

28 Sept 2002: Bob Shammas (আর) raised the record for the 1000cc class with his RB ZX-11 Turbo to 207 মাইল প্রতি ঘন্টা. and he still had another gear to go. His pit scooter clocked 28 mph during a course inspection. Jamie Barden rode his RB ZX-11 Turbo to 209 মাইল প্রতি ঘন্টা. Wayne Pollack (এল) rode his Hayabusa with Nitrous to a new record of 205.00 মাইল প্রতি ঘন্টা.

Wayne is tripping on the Dark Side to stay in touch with the God of Speed as he’s usually seen on record setting Harleys.

30 বিকলাঙ্গ করা 2003: Bob Shammas raised his record to 218 mph at Maxton. He also dynoed the bike, the results of which are posted above. Inertial dynos are not the way to tune RB Racing Turbos.

Bob Shammas only used the dyno to verify his Autocal.V6 Professional software predictions.

Sophistication and practicality

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 500 এইচপি.

We recommend a maximum of 12 psi on Pump Gas (92 octane). জন্য 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, সংযোগকারী তন্তু, 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 মাইল প্রতি ঘন্টা, running 18-24 psi with zero engine problems (Harley, বগুড়া, কাওয়াসাকি,সুজুকি, হোন্ডা, জয়জয়কার).

Vertical integration means no compromise

We have been doing fuel injected, intercooled 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. All components are designed in-house to be the best possible.

There is no compromise that comes with trying to adapt components not designed for the specific job at hand.

Dual computer fuel control system

Fuel Injectors/Fuel Control: Your RB Racing ZX-11 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. দ্য (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 এক্স 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 42 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. জন্য 475 Hp at a BSFC of .45 lb./hp/hr you would use eight 34 lb./hr injectors.

Mechanical considerations

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 এবং, as such the effective compression ratio is less than the stated 11.0 থেকে 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 Kawasaki we recommend you retain your stock connecting rods and pistons as they seem well suited for 300+ এইচপি. If you are hell bent on 500 hp then forged pistons and Carrillo rods are a good choice.

To achieve 500 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 এইচপি. Mandatory on high output turbo bikes.

ইগনিশন: 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.

Click on the title above to go to our RSR Boost Compression Ratio Calculator. This allows you to run scenarios of how boost affects your effective compression ratio as modified by altitude considerations. It will give you a good idea as to why turbos go so fast and also how to plan your motor for your particular circumstances.
