Your racing engine blew up. Now what do you do?

After that, you repair all the mechanicals that are broken. You review what went wrong. You revise your tune-up to try to avoid it again. For fuel system adjustments, try precise numerical control over tuning using air/fuel ratio! Without knowing it, this is something you already do: When you adjust fuel injection jetting from plug […]

Good Fuel Pressure with a New MFI System

Setting up a new MFI fuel system: main bypass adjustment to control the air/fuel ratio adjustment of the combination of the main bypass and nozzle sizes to maintain an optimum fuel pressure range from the lowest to highest engine RPM. Changing the main bypass jet for tuning affects the air to fuel ratio and fuel […]

Solutions to Idle Lope in Mechanical Fuel Injection

Customer Inquiry One of our customers recently inquired about idle lope in his funnycar dragster.  ‘What can I do to minimize idle surge on our funny car?  It’s difficult to stage at the starting line.  It has a Bruno (torque converter), Lenco transmission, Enderle Bird Catcher fuel injection hat, Enderle K type barrel valve with […]

Rons Low Cost Throttle Body Fuel Injection CFM & HP Capabilities

Rons Fuel Injection has provided us with air flow data for their throttle body setups.  We analyzed the power potential of these simple and very popular fuel injection systems. Racing engine size capabilities were determined at the flow CFM numbers provided by Rons Fuel Injection.  For 100% air density, horsepower capabilities were also determined. Rons […]

High HP from Rons MFI Throttle Bodies

Rons Fuel Injection provided MFI throttle body flow data so that we could analyze the power potential of these low cost, simple fuel injection systems. Racing engine sizes and horsepower potentials were determined at these flow cfm numbers for 100% air density, and are included. Rons FI MFI Toilets 3-3/4″ = 1240cfm: can feed 595 […]
