Simple Fuel Pressure Gauge for Peak Fuel Pressure Reading

We used a simple fuel pressure gauge with a peak hold needle to record our highest fuel pressure value from a run. ¬†The gauge is an all stainless, bottom 1/4NPT pipe, glycerin filled gauge with a maximum indicating needle. Glycerin filling is needed to dampen the needles from racer vibrations. ¬†Stainless is needed for resistance […]

Flatlining Fuel Injection for Max Power in Race Engines

An Advanced Method in fuel injection tuning for certain normally aspirated (NA) engines is to flatline the fuel curve. Flatlining is not always possible, especially in very high flowing cylinder heads or efficient pent roof heads on small displacement engines. However, in race engines with common wedge heads or early model Hemi heads, volumetric efficiency […]
