First of all...why does Vortech claim their supercharger will add 108hp when it seems like most people who have them installed dyno at around 280-290? It seems like there's a HUGE difference between 40-50hp and 108hp.

Anyways, aside from that, i'm assuming the s/c will basically void almost all of the factory warranty, correct? What problems could come from it? How much do you think it affects reliability?

Finally, if i were to buy a used s2k with a vortech installed, what should i look for?

i believe b/c the supercharger figures u r quoting are at the wheel, the 108 gain is at the crank.

im sure the warranty is voided, but doesn't vortech offer its own warranty? at least on the charger itself?

im assuming the best time to add a supercharger would be when ur warranty expires, its easy for some people to get to that mileage very quickly...

 

also what other mods are necessary to get the most out of the S/C?

-Steve

 

well, i by no means am an expert, but ideally, i would think an intercooler, exhaust, maybe more durable clutch/flywheel combo, upgraded spark plugs/fuel system and other minor pieces that im not thinking of, but again, i don't believe there is an exact formula, im sure there are people out there that would throw one on without all/any of these mods, its all depends on persona desire, anyone with a supercharge wanna input????

 

The Vortech 108hp increase number is at the crank. Which is still far fetched because I am making 285-290 at the rear wheels and if you add in the 15% loss on the dyno that only comes out to around 330hp, not the 350 Vortech claims.

The kit already has an intercooler(aftercooler really). So that isn't needed.

You will want new spark plugs. Right now most of us Vortech guys are using NGK copper plugs, 1 heat range colder gapped to .035

You will eventually need a clutch, would save money to do the flywheel at the same time if you want. Once you add the power, then the clutch, you will need to beef up the rear end to handle this, so kaaz 1.5 way clutch pack differental, comptech strengthening mod, possibly new axels. Or at the least be prepared to spend money to fix these parts if/when they break. You will need stiffer suspension to launch the car and wider/sticky tires. Otherwise you will get wheel hop and wheel spin.

You will want to get a VAFC to lower the VTEC point to take advantage of the boost. You will also use the VAFC to add and remove fuel at different rpm to make power and to keep from running too lean.

You will probably want an exhaust/header, but they aren't necessary. You could also do a bored out throttle body, but again thats not necessary either. You might want to get gauges and an auto timer(aka turbo timer) in order to monitor for problems and to aid in tuning the car. The turbo timer will cool the car down for you. The hondata insulator gasket, and other temperature reducing mods like the mugen or spoon tstat, fan siwtch and rad cap all help. Also running a 70%/30% antifreeze solution with red line water wetter. But again all the things I just mentioned in this paragraph are not NECESSARY but can be helpful.

In order to get any more power out of the kit you are going to have to get injectors and in inline fuel pump with some type of fuel management, or maybe you can get away with using the VAFC I don't know. After you do that you can start with a smaller pulley and smaller belt. Once you do this, the Vortech 1 year warranty is out the window...

Hope this helps.
