Paxton or Vortech

Let's just say you are making around 300 FWHP now, with 8PSI you'll be making ~420-440 with a proper tune.

Your 30# injectors will be well over 80% duty cycle(closer to 95%) at 40 psi. You'll need to run them at around 60 psi to get them ~80% at full boost. This will require an FMU and at least an external booster pump to be safe. Possibly a high pressure in-tank could work as well.

Personally I do not like running FMUs as a good tune and larger injectors are a better solution IMO. But you would need to run 36/38#ers to get this done.

a rule of thumb is 1 step colder for every 100HP, so you should run 2 ranges colder to be on the safe side.

I would prefer the Vortech SC series, but the Novi is also a very good blower. You'll be happy with either.... I would say Procharger P1SC above either, but you did not list it as a choice.

KB 2.2 i know its not a choice but thats what i like!

Lots of people say Vortech buy I'm not sure if it's because they are better. Maybe because Vortech gives people alot more models to choose from. I haven't heard anything bad about paxton. I have a Vortech...PB

procharger, yeah its not a choice but i like them because you dont tap into the oil pan and if one of them goes they both dont go if you know what I mean.

i have a vortech V-1 S-Trim and i am very happy with it. Paxton is very good too, but if you want to go with a Paxton go with the Novi 2000.

Vortech SC.
