Super charging an EA81


Recommended Posts

I live down under, and i am having some issues fitting my Garret super charger to my 83 leone, my main problem is compression settings, i have nothing to work from. If you know or know anyone in your circle who can help me out, that would be fully sick. In return i'll post photos of a hopfully successful mission, to get some more power out of the old girl via a super charger.

Trent, I'm sorry I do not know what you are asking when your say "compression settings"

The compression ratio for the EA81 in 83 was 8.7 to 1

The compression pressure is 1,177 kiloPascals. (171 psi)

Is this what you need?

The turbo's of that approx. time delevoled about 7 psi positive intake manifold boost pressure - but these had a lower comp press(ratio) --> 1,079 kPa (7.7)

Hope this helps as it sounds like a very interesting project

Care to say what fuel system you are using?

Suck through carb? MPFI?

I have been wanting to do the same thing with my Brumby
