I will check with my bud and see how he is comming
but the single blades actually will loose hp, on most engines, with the exception of turbos.
and then you best be on your game to get hp out of them then. they are more for bling,
a ported oem tb or a dual blade is the best route. we have a company working on a ddual blade, but like ronald says, I dont think bbk is gonna go into production of a tb jsut to make 1000 tb's
