IMPCO Industrial Engines The 200 VS 350 HP Rating On An EB Reg Is
The Application
impco Regulator Brief Introduction:
the 200 VS 350 HP rating on an EB reg is the application. The reg
is rated at 200HP for industrial engines. Industrial engines
usually run at a fixed 1800 RPM and the water pump is geared
different then automotive applications. The limited water supply
means the reg is derated to 200HP. On vehicles the water pump can
increase suction as the RPM is quite high at full throttle. This
means more flow and heat for the reg so the HP rating is higher.

questions about Impco E-regulator
Franz is pretty well right on the money with his comments. The P
stands for positive pressure. These regs put out 3" to 6" positive
pressure WC. They are used strictly for NG.
The reason for the 200 VS 350 HP rating on an EB reg is the
application. The reg is rated at 200HP for industrial engines.
Industrial engines usually run at a fixed 1800 RPM and the water
pump is geared different then automotive applications. The limited
water supply means the reg is derated to 200HP. On vehicles the
water pump can increase suction as the RPM is quite high at full
throttle. This means more flow and heat for the reg so the HP
rating is higher.
Lastly, personal opinion, I prefer the E over the L. The E has a
water chamber the size of the reg. Heat transfer is great. The L
has a U shaped tunnel through the reg and heat transfer on a cold
engine is poor and wide open throttle is no where near as good as
the E for heat transfer. In addition the L has a primary seat
activated by tank pressure. The L seems to have more P seat
problems than the E. We experienced a higher number of problems
with the L's at our shop.
