Headers for supercharged fronty

[nismofan01]

actually the reason why they say they are not for the 3.3l supercharged motor is because you will be getting alot more flow due to the removal of your cat you will actually add PSI, so lets say your truck is running 6-7psi of boost stock now you might be 10psi, when i first heard this i laughed and was like yea ok but i chatted with a tech from jackson racing and he told me that by freeing up exhaust flow you will spin the supercharger faster...thats the only real reason why i could think they would say its for the N/A 3.3l only, maybe they dont wanna be held in account of engine issues or something, im sure they will fit to me the only differance in the s/c vs se or xe is the supercharger, i would go for it.

i don't agree with that nismofan.
I built a race motor for a customer of mine, honda civic. He ordered a ton of parts with a jackson racing supercharger. The parts he brought to me were setup for turbo. But that isn't the right thing to do. Supercharged motors need the backpressure to build the boost against. When you free up the flow on a supercharged motor it actually looses boost because it doesn't have much to build pressure against.
I do agree that you have to overdrive the supercharger to get the same boost pressure, if you free up the flow. Therefore it works the supercharger harder, decreasing the life of the blower..
And removing the cats won't make the motor spin that belt any faster than if the cats where there!
hope this helps...

I am replacing the cats only because the fronty has a code P0430. I bought some Magnaflow cats replace them.
I have performance Exhaust, K&N air filter and a smaller 2.4" pulley. I would like to install an electric fan if I can find one that will fit without spending $400
Is there anything else to do to get more power out of the supercharged fronty?
