| PASSION RACING ENGINES specializes in high performance modifications exclusive to Yamaha Banshee engines. Every engine is custom built to your needs and wants with current and future mods in mind. This insures you will receive a custom hand crafted engine designed from the ground up for your specific needs. We do not offer blister-pack (STAGE) motors. Each customer is questioned and counseled on a personal level to achieve the desired results. All engines are personally designed, ported and assembled by James Smart, who has over 30 years in 2 stroke engine development and modification. His designs have been shipped around the world and are a dominant force on race tracks in the USA and abroad. Each engine is designed for type specific performance and utmost reliability in mind. PASSION RACING ENGINES also offers various engine,exhaust, and induction components that are specifically type matched to your individual engine design at competitive pricing. 2 CYCLE ENGINEERING DESIGN AND DATA SERVICES Due to overseas shipping complications in some country's around the world, some of my otherwise potential customers have found it easier to let us design and engineer performance packages and supply all needed engineering data and porting designs for their intended applications. These engineering packages include complete porting design for any application including all time/area calculations, port efficiency data,basic port lay-out, port preparation data,cylinder prep and build advisory commentary. In addition , Passion Racing Engines can also include in these packages full combustion chamber and head design for gasoline or methanol,expansion chamber design,complete with full engineering data back-up. These engineering back-ups cover all applicable data for inspection by professional engine builders to build directly off of, making the entire "package" easier to understand just exactly what is happening from a overall view. I also may provide much more extensive balanced resonance , pressure ,velocity ,and combustion data in some cases among numerous other complimentary design parameter comparison data. All 2-stroke engines operate by the same laws of physics ,so this service is NOT limited to just Yamaha Banshee engines. Anything from awe inspiring chain saws to record setting road race engines can be built from my data. Contrary to what you may have read or discussed among friends, effective type specific 2 stroke engine design processes ARE an exact science. Although the mathematics involved are far beyond the capability of most individuals ability, I've devoted my entire adult life to this science and I've pioneered and re-defined some of it along the way. My relentless passion and devotion to this science over the last 3 decades allows me to produce with certainty, completely mathematically balanced and predictable engine designs with amazing accuracy. If this type of service is needed for you or your race team's horsepower addiction, please email (only), me with your situation containing your specific needs,and we will make you the dominate force to be reckoned with. PLEASE, only email's will be accepted concerning engineering packages. I have a tremendous phone backup already with my engine building service and simply do not have that many hours in a day. I trust only myself ,so I'm a really busy guy while building my customers engines. I reserve the right to decline this service in some cases for I would take it quite personal to be defeated by one of my own designs. After all, 2nd place is just another way of saying "1st loser", and that is an emotional experience that I have successfully avoided through my endless efforts, as well as complete exhaustion.....James Smart |

AFTER 3 YEARS OF RESEARCH AND DEVELOPMENT SNIPER RACING PRODUCTS AND
PASSION RACING ENGINES ARE EXCITED TO ANNOUNCE THAT SNIPER ASSASSIN INFRAMES
ARE HERE!!!!
LATEST NEWS ON THE SNIPER ASSASSIN INFRAMES
| INTRODUCING 21st CENTURY EXPANSION CHAMBER TECHNOLOGY FOR YAMAHA BANSHEE HAND CRAFTED IN THE U.S.A. |
| Using global research efforts from the minds of Professor G.B. Blair (unsteady gas dynamics), Bernoulli(static, dynamic and stagnation pressure),Hermann Von Helmholtz (resonance management), Fujio Nagao and Yuzuru Shimamoto(Factory Yamaha engineers) along with comparative complimentary parameter observation software development from Gary Bilby of TST ENGINE SOFTWARE and port efficiency design,combustion chamber design,initial pulse velocity and convection heat transfer research from James Smart of PASSION RACING ENGINES, we have produced the highest wave amplitude and pulse efficient expansion chamber ever offered to the general public for the Yamaha Banshee. Every individual section of this chamber is velocity and resonance matched from front to rear. In short, it comes on like an atomic bomb and just never seems to shut off. Couple this with high quality manufacturing and aesthetically pleasing function, and you have an investment grade power pumping monster. It easily out performs ANY production inframe or out of frame drag pipe offered by anybody anywhere....period!!!! Standard models were specifically designed for high BMEP engines from 392cc-485cc. This is ABSOLUTELY "THE" CHEETAH CUB PIPE OF ALL TIMES. We also designed pre-production alteration abilities to expand specific application capability's and engine formats,so we can tune your pipes for your engine at a pre-production level. Never has this level of precision tuning been offered to anyone that asks for it. We offer these chambers in Bare, Industrial Grade Electroless Nickel plated(inside and out), and 1700F rated ceramic coating. Chamber bodies are TIG welded for the cleanest possible welds. All sets come with 6061T6 aluminum billet silencers(resonance matched) with stainless steel perforated tubing and stainless steel packing(no more re-packs!) .All mounting tabs are beyond rigid for years of service. Industrial Electroless finish can be be heavilly buffed a multitude of times to bring back finish!..does it get any better? Chambers were specifically designed to be infinitely adjustable from front to rear to insure fitting options required for different carb, filter applications. They will clear the biggest mono-blocks and even the RZ Yamaha series cylinders. We tried to cover all the bases on function. Petcock and plug access are excellent. They are symmetrically matched from side to side giving the most efficient slipstream possible. We also offer custom tuned to your engine hybrid out of frame versions of this pipe. Optional interchangeable stinger section versions also available for custom tuning at the track or as the need arises, you know, when you cant get past that need to REALLY rub it in!
