Vtec has nothing to do with how much power a JRSC will put out. Out of those 3 choices I would go with the Y8 because it's better than the Y7 and the mini me's compression would be too high. I would never supercharge a honda though.
The compression will only be in the low 10s. Which is stock B16 territory. It's not too high at all.
As for supercharging.. my buddy Chuong runs a 13.5 @ ~89 with Hondata, JRSC, ZEX Stage 2 Cam, some other little goodies, but stock internaled (minus the cam) Y7/Y8.
It's a very nice setup. I've spent all my days trying to catch him, and haven't been able to do it.
..now, as for how much of that is VTEC? ..probably not a lot, but the extra compression gained by the mini, plus the longer duration on your intake stroke will definately help when trying to force air into the chambers will th JRSC. I just don't know exactly how much horse would be generated by it.
I thought the compression was in the high 10's on a mini me? Low 10's is still kinda high though if you don't have proper fuel management and tuning. I was just assuming he was going to slap a JRSC kit on there and use an FMU for fuel management. I think your assuming he already has good fuel management and the car is going to be tuned really well.
I still wouldn't supercharge a honda though because, well it's a 4 cylinder grocery getting honda. I mean you cant really upgrade a supercharger that easy can you? Maybe throw another belt on on to run more boost? You could also do a turbo kit for much cheaper and it would be easily upgradable. I guess if your stuck on getting a supercharger it can work out pretty well just likes your friends car did. :wink:
Hahah.. that could be (with the tuning). I sometimes forget that the masses still use crappy fuel management. But, that's why we're here, eh? To educate the masses!
I think he picked up the supercharger like dirty cheap. He's like me, dude. He's not a "kit" guy. He just got a good deal on it. It's amazing. It doesn't "feel" fast, but it's done w/ the 1/4m before you realize.
As for upgrades, ya, pretty much just upgrade the pulley for more boost. A JRSC isn't worth anything after 9psi, though. Just a big heat blower.
...side note, I think he ran that on a 6psi pulley or something. Crazy low end launches. Like 2 flat 60', maybe 2.1 I don't really rmember, but it was maddening.
