not really, thumper is a genious when it comes to porting E7s. I have yet to see anyone able to reproduce his results....same goes for Tmoss ported lower intakes. match the two of them together and you've got one mean sleaper.

All that guy is really doing is adding bigger valves...which in most cases casue P/V clearance issues. thumper has the option of GT40 valves but you are sacrificing low end tq for high end HP with bigger valves. powerheads is another option, but again you run into the bigger valve clearance issues.
