EFI or Blowthrough?

that brpv works like a champ ive tried a few of them. this one definitely works and works well. the other ones wouldnt open all the time or would leak or wouldnt open all the way. this one opens all the way every time.

this is why i'm thinking efi now. spent the money on a built carb for forced induction and now I have to add bits and drill holes. might as well sell my carb and msd 6530 and go efi.
