We have the best to offer in Electronic Fuel Injection for ANY racing application.
Typical Applications & Advantages
E85 has the biggest advantages on Supercharged and Turbocharged engines. Used mainly as a replacement for race fuels, it has typically allows us to achieve at least 10% HP gains at the rear wheel while costing less that race fuels. Customers have reported that they will spend on the average of $85 for 5 gallons of racing fuel where E85 is currently about $8 for 5-gallons. Since most alcohol fuels run cooler customers usually report that the cooling systems typically run 20 degrees cooler than on gasoline.
Example: VP C16 is averages about $85 for 5 Gallons. Today E85 was $5.80 for 5 Gallons. If I burned the same 5 Gallons of E85 at 47% increase in flow I would be saving $75 for every 5 Gallons that I used.
The Dyno Graph below are actual tests from the same car and engine with E85 (RED) and Race Fuel (BLUE) - Tell me THAT don't make a difference. Picked up 60 HP at the REAR WHEELS!!!!!!!!!!
FAST and BigStuff have had capabilities to operate on Alternative Fuels for many years now. We currently run Methanol on MANY of our customers cars. The advantage for us is that we eliminate the Intercooler and support items which are a tremendous cost savings plus a huge weight savings in the front of the race car.
First, most EFI cars can operate on E85 with some changes but to have a “Flex Fuel” car certain changes are normally required. FAST and BigStuff are working with Alternate Fuels and have incorporated capability into their new computers for E85 and other fuels.
(A) Flex Fuel compatible ECM like FAST XFI or BigStuff 3
Vehicles using these ECM’s may utilize E85 or other fuels like Methanol without the use of the Fuel Composition Sensor and not use the FLEX mode.
Installation of the Ethanol Composition sensor into the fuel supply or return allows the computer to read the percent of Ethanol that the motor will be burning. E85 (85% Ethanol and 15% Gasoline) fuel would require about an additional 46% fuel as compared to gasoline. The computer tests for the amount of Ethanol then modifies the fuel injection output to provide the proper Air/Fuel Ratio. Typically “pump” gasoline is burned at a Stoichiometric A/F ratio of about 14.5:1 A/F where E85 would be 10.0:1 A/F. The incorporation of the E85 Sensor along with the software in the computer makes sure that this gets done correctly.
Above is the Flex Fuel Setup Page for FAST XFI
People that might drive their converted cars in the winter months might see some longer than normal cranking times when starting the motor in cold weather. However, since the word here is Flex Fuel, the car can equally be driven in the winter months on standard fuel for best economy. Also, the program in the computer allows a different fuel warm-up correction based on the Ethanol content.
E85 burns at a lower A/F ratio thus the more Ethanol present in the “mix” the worse fuel economy the car will see. Although the economy issue is one way to look at things, the other way is that even if you burned 2X the fuel on E85 you would still be saving mega dollars as compared to driving the same vehicle on Racing Fuels.
