I've always heard you could not supercharge a n/a. But I have seen sites selling superchargers for the n/a, like E-ram electric superchargers and typhoon centrifugal superchargers. Anyone have any input on these and if they work or a gimmick?

 

People that say you can't supercharge a n/a motor usually have their heads where the sun don't shine. The electric superchargers are a rip-off / farce. You can supercharge a n/a with either; a screw type, like an Eaton, that comes from the nissan factory on certain other vg motors; or a centrifugal type, like the paxton or vortech brands. None of the above types, that I know of come in a kit that you can just bolt up to a Z. It would require some mild engineering and fabrication to put a supercharger on a Z.

There are plenty of people here who will scream about all of the drawbacks of supercharging the n/a, but it can be done relatively safely at low boost levels. 6 psi is around the max boost on stock internals. Should get you close to 300 rwhp.

 

zgringo here claims to have done it. i am yet to see a vid of one in action.

 

LOL, he sure felt stongly about his water / alky injection kits. He went away once his alter ego, the "banned member", left.

 

it's not taht you can't supercharge an NA, it's that it's not smart to do. to use an eaton style, you'll need a whole new intake manifold that you'll have to fabricate from scratch. You'll have to use a voltech style blower and fabricate piping into the intake. Not easy, not all that beneficial due to a high compression ratio to begin with.

 

you can supercharge anything, just like you can turbocharge anything. Reliability and cost are the factors... it's more reliable and [generally] cheaper to swap in a TT motor, and you'll generally make more power doing it as well.

And I 2nd CanyonCarvers comment about electric superchargers... they generally actually cause more restriction in the intake than boost (they can't spin fast enough off a cars electrical system to overpower the natural suction of the cylinders)
