BIG misconception with these pump!!!!!
WALBRO 255LPH VS. SUPRA TT FUEL PUMP
With the Walbro install and a static fuel Pressure gauge on the Dynopack we saw that It did flow what it advertises but when we applied 100% throttle after 4 secs the fuel pressure started to DROP. It could NOT KEEP UP with the fuel consumption of the motor under higher RPM/Boost. DROP in pressure=LEAN which = catastrophic damage to the motor.
The Supra Pump on the other hand HELD the pressure thru out the WHOLE RPM Range. SUPRA PUMP= WIN
There is a reason why theses pumps are $85 vs the Supras $200 price tag.
