Hopefully ill be getting a sos supercharger kit in the near future ive been debating over one and the greddy kit the past month and am leaning toward the supercharger.
i see it comes with a plug and play type system but i dont see if it comes with a base tune or not? do i have to get something to tow my s2k to a tuner? and can you pay a tuner to use the plug n play or is this not enough and im going to have to buy a tunable software like kpro as well? i just want to know whats needed b4 i can have it on the road i read a big thread on sos supercharger on here already but i didn't see the answer about tuning sorry if i didn't search good enough !!

 

if you have an ap1, then the complete SOS kit comes with something that is not tunable. you would just buy the kit, install, and go enjoy a little more power than stock.

if you want to have it tuned to your specific car, then get the tuner kit and an EMS (either KPRO, AEM or haltech, if you have an 00-05)

 

can also buy stage 2 from SOS, comes with EMS & injectors etc

 

the stage 1 kit is tunable, to a limited extent. The "tuning" is getting the fuel pressure dialed in for the most part, by adjusting a screw. You really could tune it yourself if you had a wideband, though tuning it on a dyno+wideband is better. It doesn't really require the specialized knowledge that a tuner working with the Kpro or AEM would need. I'll just say if you get any forced induction solution, you MUST get a wideband O2 sensor and gauge!

The plug and play module has a few different profiles, though. The stock FVM module is made for a stock car, though they do have another flash for a car with bolt-ons that kicks in more fuel from 6000-6500 and (for me at least) doesn't run as rich at redline. You have to ask for that tune as it requires a reflash. There's no "on the fly" changes you can make to the module. Their black box is superior to Comptech's as it has fuel, VTEC, and MAP clamping, whereas the Comptech only has the latter.

Still, the Stage 1 kit is pretty well done for a 100% stock car, and power gains probably won't be all that much if you go with a standalone ECU at the stock boost level. You could drive it out of the box and likely not have any issues, though I wouldn't mash the throttle until you have verified all is well with air/fuel ratios. Their alternate FVM maps worked really well for me...my car pushes 306 on a Mustang dyno at 95F, +115HP over stock. I just moved up north and in cold weather, it's putting out even more than that!

If your goal is more than "just over 300" you do need a standalone ECU and specialized tuning.

 

Get the SOS with the 1200 blower for sure!! With ems and injectors can make lots of power with that setup. Basic stock boost kit you can use as it comes without ems.

 

Yeah 1200 all the way, don't even screw with buying these kits with rising rate band aid devices, end, injectors, and tune all the way.

 

These centrifugals, from my experience only makd considerable usable torque when you can install a pulley that gives you a solid meaty amount of boost from 5k+ up to a screaming full boost on the last 2500 rpms.

The factory pulley, you might see 3 psi at 5000 rpms, just maybe and you'll see 4.5-5.5 psi only around the last couple thousand rpms. So, install a pulley that boost 14 psi, you'll see around 2.5x more boost and the same comparable rpm. So, instead of a meager 3 psi, you'll see more like 6.5psi or more.

It's really about cfms though and the 1200 is the way to go

 

Seems the centrifugal superchargers are very favorable for our cars and they don't tax the driveline as bad which would result in more money being spent. I haven't had a turbo s2000, but plenty generate a solid 350 ft lbs of torque and maintain it for a broad powerband, which taxes transmissions and differentials more

 

Yeah but they make you grin all damn day long instead of waiting for it!

 

your tellin me all i gotta do is put on a smaller pulley that makes it 14 psi with no tuning involved and no other upgrades to have 14psi on this kit?
