Have u guys seen the gem' wagon in the new issue of ff&R????
Thats mean as!!! how do iu build a motor like that???
question..............
How hard would it be fit a supercharger like that with the necessary mods to the engine (INCLUDE A DOLLAR FIGURE AS WELL), including the fuel injection. Would I be better off to get a piazza motor or similar and drop it in???
What complictions will i have concidering some kind of force fed induction?

I noticed that u guys mentioned earlier carby' turbo options earlier, I would assume the EFI would be a lot more effecient, however i believe that the EFI may be overated on a gem motor because the only cost effective way to build it would mean squirting the fuel into a chamber before the head and the cylenders sharing the mix instaed of having individual injectors for each cylender- am i right / wrong?
ps- a solution that would eliminate the chances of detonation, pinging and other unwanted situations or sounds would be nice but if i am asking for a miricle please tell me in the nicest way.

Thankyou

Yeah I gotta admit that thing looks mad! Suck though supercharger (if I'm not mistaken). Should be easy to find a 4agze supercharger however fitting the bastard could be a huge problem.

Looking at the pictures it looks like it would be a VERY tight squeeze in a standard Gemi (and that Gemi in the mag is nowhere near standard!).

As far as the motor goes, you'd need huge modifications to be able to withstand the pressure it would be forced to take. Every moving part nearly would need to be replaced.

Legally you may find some problem depending on what state you're in. And I don't see it happening without a lotta $$$ being spent.

not exactly. it depands on the size of the front pulley. the small the pulley, the larger amounts of boost you will create. sorry if im wrong, but with the standard magnetic clutch on the super charger itself on ran the motor at 5-7 psi of boost. ive seen those chargers put on commodore V6 motors and have been run with out any mods to the engine. dragos van is supposidly running at 15 psi! with a 8.5:1 compression ratio. in that case yes the motor will need to be very well done and have big bucks spent.
