We've seen plenty of dyno numbers on these intakes already. They make a solid 15 rwhp on the top end and all through the mid range power band. If you lose any power it's well below your power band and shouldn't have any effect on a race. Also, 15 rwhp on a car making over 550 hp isn't something that should make a night and day difference. It's about a 2% power gain to kind of put it into perspective. If you really want to feel a big jump in power you'll need to look into long tube headers or some pulley work!
