80 series power upgrade

[88 Shorty]

Hello,
I've heard you can make petrol 80s quicker by advancing the timing, how much does this need to be done by please, also what size exhuast etc is best.


Thanks

You can, but are you willing to run premium unleaded??? If so, advance it to 6 degrees from 3 and put premium in...if u use normal fuel, you will go backwards in power. Cut the 2 into 1 piece off the engine pipe and put something descent ion there, and dont touch the system unless yu want it to be loud. If u dont mind, loose the round muffler for a nice free flow one...the other two mufflers are straight through.

Also, if you do this mod and the motor pings / nocks from using standard unleaded a sensor detects this and automatically retards you timing back to the way it was or possibly worse.
Correct me anyone, if I'm wrong as I cant remember where I got this info from.
