Of course the mods are not exactly the same as the other poster but given that nobody else seems willing to post up before and after dyno's or simply hasn't done it then I put my data up as a point of interest for comparison. It's not the be all and end all but at the end of the day I am not making these numbers up or telling you how it feels. I am just showing what those mods mean. My dyno plots show 5bhp or thereabouts for the intake, plenum and throttle body.
Nobody is questioning your intake. I'm sure every home DIY'er has got largely the same thing just made a slightly different way. Mine was just simple aluminium tubing and 4 ply silicone hose. I'm sure yours like mine is not using some fancy engineering computer program to test for optimum flow etc.
I wouldn't read too much in to the power and weight of other cars because if you go that far then you might as well consider diff ratios and gearing etc.
