The FLYING TOILET SYSTEM is not only the most widely used but it is the "WINNINGEST FUEL INJECTION IN THE WORLD". This system has been in production almost 30 years and can be found in the winner's circle every weekend in drag racing, boat racing, tractor pulling, on the salt flats, in the mud bogs and who knows where else. We're sure there are probably a few applications we are forgetting. This system comes complete with everything needed for a "bolt-on" installation that can be accomplished in less than a day in your shop or garage. Most importantly, it is the most affordable, and yet hassle-free, fuel system on the market and will surpass any alcohol or gasoline carburetor performance numbers, period!
The most common use for the FLYING TOILET SYSTEM is atop normally aspirated drag racing engines. That is what we focus on at KillerRONS.COM and what we are good at! Below you will get an overview of the three basic FLYING TOILET set-ups.
The smaller throttle body (3-3/4" - 1240 CFM) is identifed by a black throttle blade and is reserved for 327 to 383 cubic inch engines where the owner has no plans of going bigger in cubic inch in the years to come. This throttle body typically is utilized with a "0" pump and flowed nozzle jets ranging from #29 to #35 nozzle jets.
The middle-sized throttle body is the most popular with a 4" (1435 CFM) throttle blade. This red throttle blade unit has a wide span of cubic inch compatability ranging from 355" to as much as 502". This throttle body can work with a "0" or "0-1/2" pump and typically utilizes flowed nozzle jets ranging from #32 to #37 nozzle jets.
The biggest throttle body features a purple throttle blade and comes in at 1800 CFM (4.100"). This unit is set aside for the bigger cubic inch/higher horsepower applications. Engines from 421" to 572" can put this throttle body to work. Typically this throttle body will be mated with a "0-1/2" pump that will feed approximately 1000 HP with as big as #41 flowed nozzle jet.

FAST FLYING TOILET ANSWERS
Mechanical fuel injection operates at very high pressures so there is no worry of "fuel sloshing" under acceleration. Due to this you can mount the throttle body in any direction on your engine.
The Flying Toilet's base flange is slot-drilled to work atop either a 4150 or 4500 pattern manifold. The top (air cleaner bridge AREA) is modeled after a 4150 so it is 5.00" across. The throttle body is 4.625" tall.
All Fuel delivery components are hard anodized and alcohol compatible seals are used throughout making the system impervious to the much-debated effects of alcohol on metals and rubbers.
The throttle cable lever comes standard with 10-32 thread but the lever can be changed to 1/4-28 thread if the customer desires. Throttle throw from idle position to wide open throttle is 2.00". The shaft is 3/8" in diameter and features a pair of built-in return springs (one each side).
Throttle cable anchors and scoop mount kits can be seen here.

KillerRONS.COM systems are tailored to your combination by skilled technicians who have championship level experience using these systems. In most cases your system will ship no later than the next business day.
Most customers drill and tap their own manifolds following this procedure. If you are uncomfortable with this we can do it for you on the CNC machine for $150. If you need a new manifold we are a dealer for Brodix, Dart and Pro-Filer and would be glad to make a recommendation for you. Gasket matching porting is avalable for $225-$275 depending upon the manifold.
