Evening

We are working on our Supercharged upgrade and we are receiving conflicting information over what is the optimum Air fuel ratio (AFR) for a Supercharged petrol engine.

We currently 'see' an AFR of 10.5 on standard RRS SC and this means that the car is running far too rich!

Anyone who can assist us with a bit of scientific knowledge will be greatly appreciated Chips with everything

I already have a dyno and 'sniffer' as you put it.

What I'm after is some reliable knowledge on optimum AFR for Supercharged engines.

Thanks anyway  Chips with everything

the targeted air fuel thats optimum for charged engines are around 12 to 1 does this help its what we run them at more fuel like 10.5 to 1 the egt start to climb and cats are being worked to hard 2006 Range Rover Sport Supercharged Speedinnovation Custom upgraded supercharger pulley,exhaust, tv mod,smoked lights, smoked side markers, 23" rinspeed wheels, 315 tires all the way around, arden kit
