The Dyno Shop’s
Fuel Flow Bench is Equipped with features such as:
- (engine) rpm
- 2 x flow sensors
- 3 x pressure sensors (250psi max)
- full data log and computer system
Basic Fuel Flow
- Free Run (Zero to 10,000rpm run- no pressure, “pumps potential”)
- STD test Zero to 10,000rpm (Zero to 10,000rpm run, with pressure set at 100psi @8,000rpm,)
- Pump Health test (8,000rpm with Zero psi, up to 180psi)
- Price: $150 inc
Receive a full printout of each graph at std increments.
Full System Test
- testing manifold, Hat, Port nozzles, Barrel valve, Check valves, regulators, and pump
- Observe how your system actually operates in a controlled environment
- 2 flow points available
- Pump, Lo Speed and High Speed pressure points
- Price: from $500 (depending on complexity and customer requirements)
Receive a full Printout of each graph. Be involved and gain a better understanding.
- Nozzles Pills, Jets
- Calibrate or re-calibrate
- Peak flow “max out”
- Price: $50 + $3.00/piece)
Receive spread sheet with sizes against flow figures.
All tests can be modified to suit your needs.
Commonly problems associated:
- pressure rises and flow begins to slow
- pressure and flow reach a peak (below the pumps required ability)
- pressure increases and flow decreases
- pulsing (makes it impossible to get any reading, should not be used in engine)
A pump can be used even if it shows any of the above symptoms. Knowing the characteristics allows you to compensate with setup.
The graph shows a “Pump STD test”
- You see an example of why you can no longer rely on the old method of reading gauges and writing them down
- The cursor is set, with pressure set at the standard of 100 PSI @8000 RPM
- With this pump flow and RPM are linear, but when the pressure approaches 100PSI the flow begins to drop off (it is still considered a good pump)
- The bar has been raised in the blown alcohol game where 8,000 RPM is no longer within a competitive range. we are commonly seeing engines push 10,000 RPM and thus the fuel systems should be tested there.
