    I just picked up a Vortech kit with 47lb injectors and a SCT tuner. My car is my daily so what will I need to upgrade or add to the kit to be around 650-700 whp reliably. My car is a 15 manual and it will be on pump 93

    Might be fine for 600-650. Not sure, even if BAP the 47lb injectors can only go so far. Maybe call up Beefcake or Lethal and see what their opinion is for your goals.

    56# injectors and a BAP on the stock pump should get you there on 93. I'd be skeptical of the 47's at the HP level you are seeking but I am a PD guy. Centri's tune a little leaner than PD setups on WOT, so you may be okay. However, always better to have plenty of injector than to later find out you were border line static at the top of your RPM range and go lean. A lot also depends on where the tuner limits the RPM range.

    1050x + BAP would be my choices

    56's(preferably 72s), BAP, long tubes, 18 manifold and a tune will get you 650whp. The main gain will come from the 18 manifold letting raising your peak power to 7800rpm and the additional boost you'll see. From there the injectors and BAP are just support mods for the additional boost and RPM's you are going to see.

    I made 652 on a 90 degree day with a redline of 7200rpms. You can see my mods in the description below.

    Basically to get you to 600rwhp with that kit you just need a stronger injector and a BAP. (Those injectors are only rated for about 500hp in forced induction applications per LMRs website). I have the 1050Xs which are about 100lb/hr and they are great for 93 and can support E85 if you ever switch, but for those power levels you only need a 72lb/hr injector as mentioned above. If you want to get closer to 650 you should get headers and exhaust.

    This is a big debate, but to me there is really no need for OPG at those power levels if you keep the redline low and don't hit the rev limiter a bunch. I am doing my OPGs, because I am going to pulley down again and raise the rev limit to 7500 to get me close to the mid 700s on 93 and Torco. If you don't raise the redline too much there is not really a need to switch to the 2018 manifold either, as the 2017 one makes plenty of power at the stock RPM range.

    I maxed out the procharger injectors on 10 psi. I went 1000cc and BAP.
