Fitting blower - does compression need to be lowered?

Hi, i'm currently looking at buying an AU (4.0) with a supercharger. When the blower was fitted the compression wasn't lowered - is this likely to cause any problems? Is it always necessary to lower the compression when putting a blower on?

Re: Fitting blower - does compression need to be lowered?

No not nesssessary so long as fuel and advance curve is correct.Usually over 10 Lp boost the compression needs to be lowered.Generally..
Capa s/c the Gen lll and its compression is 10 to 1....
