trying to buy a boost gauge and i like the blitz one.
im looking at the blitz site and i see 2 kinds of MD boost gauges. the "MD Boost" and the "MD Boost Mechanical"

the mechanical one is cheaper and i cant find any information on how the 2 are different.

also where can i get holders for the gauges? thanks

 

The higher priced one is an electric boost gauge, while the mechanical is...well mechanical.

Electric = vacuum tube to sender (usually hidden in engine bay), then electrically linked to the gauge

Mech = vacuum tube from the engine to the gauge.

 

I wanted one for my FD but they dont come in 52mm to fit in my RE-Amemiya steering column pod

 

does it make any difference? is it worth it to pay the extra money for it to be electrical?
