Rev Limiter for MGB Survival

We surmised that we over-revved the MGB engine in the first race of 2012, because:

    1) there was no tachometer

    2) there was no speedometer

    3) the engine is underpowered, causing drivers to floor it all the time, for the entire 14 hours

    4) the 4 speed manual transmission really really needs a 5th and 6th gear, causing drivers to floor it all the time, for the entire 14 hours

So we installed a tachometer from another MGB and rotated it so that 5250 is pointing straight up - she really could use a "shift now" light for gears 1, 2, and 3 and a "sit back - you're just along for the ride at this point" light for 4th gear. Some day.

We installed a Rev Limiter instead since our driver pool is often hungover and barely focusing on the road ahead much less the little numbers on the tach.

The Rev Limiter we ended up with was the Procomp Single Stage Rev Limiter PC2031, and it did just fine as far as well could tell.

Also on the menu was a new fuel pressure regulator, the Holly Fuel Pressure Regulator had died after a failed attempt at rebuilding the internals with new rubber and filter element. Oops.

All those pretty blue AN fittings were a real pain to match up, but they sure mate nicely and are clean etc etc. Soooo un-MGB like.

MGB Fuel Pressure to Weber Carb should be about 4.5 psi and very shiny.
