DAMN, 500 n/a I would gladly pay for a set like this, and not have to worry about boosting a high compression motor!! And for the nitrous folks, yes its much cheaper, but that sh*t runs out....this wont
And for me, someone who couldn't care less about E.T.s because I prefer to turn, that is a really really tempting setup. The "MORE POWER!!!!" bug is tough to fight, but I have to be realistic here. Beating the crap out of a blown motor for extended periods of time is tough, N/A is way safer. And I'm not good enough to race a 600 hp car anyways.
