Inliners International Forums General Discussion Hi Performance Triple Side Draft Weber Question

I was looking on the clifford site and did see a setup that was dual Weber 38/38 DGAS Carbs that was impressive looking, they boast that it adds, "120% Torque & Horse Power & 10 MPG better than stock." Show me the data to support that claim and I might just drop that much cash for it.....it is good lookin though.
