Hey, I am currently looking into buying a Comptech or Vortech supercharger. I am aware that you are able to upgrade the pulley for more horsepower, but since you are at a set amount of boost you are able to push, how are these guys pushing over 400whp with a supercharger? What I am asking is what kind of mods would be needed to do so besides increased fuel to the engine, a reinforced back end and an EMS?

 

You can upgrade the Trim will net you more HP

You will need bigger injectors, heavy duty clutch/PP, EMS and fuel pump

 

i would look under the fi thread. there is a guy in the gateway region with a fully built motor pushing that much.

 

i'd say a thicker head gasket, smaller pulley, larger injectors, a standalone engine management, upgraded clutch. of course, either an intercooler or aftercooler as well. you should have an upgraded fuel pump from the start as well. you could get a puddydifferential for it be solid but you can also just run with stock or slightly upgrade with a comptech reinforcement.

 

can you please shoot me the link for the fi thread if you have it handy

 

SOS supercharger can get over 400 too. Check out their website.

He's pushing around 475WHP on his Vortech.

 

That is pretty close to 474.9 rwhp.

You want 400 rwhp you need to spin the blower faster, get an AEM EMS, 750cc injectors, a good tuner and raise the redline.

Head work, headers and a 3 inch exhaust will make it easier to get there.

 

just finished a comptech upgrade, head gasket, little head work, smaller pulley, 750 cc inj, aem, much larger radiator for air to water, bigger pump, 400hp at wheels was no problem.

 

I'm going to say head work is mandatory for 400+ with SC. You'll definitely need a new map sensor as well.
