Look at the first pic,where those 2 hoses meet,thats the supercharger.I agree,the intercooler isn't doing much Whiskey and I'm not even sure I can see an actual grill that air passes through.If ya look at the HPI site http://www.hpiracing.com/index2.htm the guy says he dyno'd it and it gained 1200-4000 RPMs depending on Air/Fuel mix.Wether it works or not it's pretty damn cool...I wonder if a turbo would be possible that small.As far as weight goes...I don't think thats too much of a factor to him,haha.
