Flap opener back-fire safety protection

The chance of getting a back-fire is the highest during the starting procedure. And only to be expected if plug leads, coil, distributor output (voltage or correct timing advance ability) or throttle potentiometer faulty, and these issues are not uncommon with most V8's over 3 years old.

For all Rover injection engines pre-1990 (flapper type)
  • Offer active back-fire protection
  • Improved power efficiency and response
Without the need to draw the ‘flap open’ your engine will gain significant power.

Ignition system condition check list

(very important for any amp upgrade to function correctly)
  • First remove advance vacuum pipe from intake and check for positive vacuum when throttle is applied.
  • Check (if fitted) that the vacuum delay module is not blocked.
  • Check positive vacuum will pull distributor advance while also checking vacuum module is not holed. (when sucking the pipe, the base plate of the distributor should rotate anti-clockwise about 15 deg.).
  • Check condition of rotor arm for signs of damage or arcing, also check the cap and clean the contacts (better still, fit new).
  • Check rotor for free play, there should be none, both rotationally and side to side.
  • Check rotor will turn clockwise through about 20 deg, and smartly retracts back to it's home position under good spring tension.
  • Distributor output is known to be weak so upgrading with our spark amp is recommended. (see below).
  • Replace plug leads, preferably with Magnecor. Use good quality plugs such as NGK BP6ES, but avoid fancy plugs, as they don't normally last long.
