It is just a personal preference. I have been in a few impressive turbo cars, I just want to SC.

 

Kraftwerks with AEM is listed as 6k out the door and the SOS 2 with upgrades and AEM looks to be about 7,100.00. Hard not to go with the cheaper option but the SOS appears to be a better kit.

 

Hit up moddiction. They're having a deal on kraftswerk

 

If you think 400whp is the most you're going to want, then pick the cheaper option.

If you have any intentions of bumping this number up, get the SOS.
I also must add, SOS has beyond amazing customer service. Buy your kit new, used, whatever, they're there to answer your questions, ship you extra parts, whatever.

I can't speak for Kraftwerks but definitely made my SOS purchase and installation smoother

 

i have the new kraftwerks kit and i can tell you DONT THINK AND GO WITH KRAFTWERKS! i do amazing power and a lot of TQ ! 421whp and 280tq

I know the Kraftwerks kit make more TQ than SOS.- good luck!

 

Kraftwerks or sos is the way to go. I'm currently running a vortech kit making just over 420whp. I'm thinking of switching over to the new Kraftwerks kit though as I'd love to try it out. We've been selling a lot of their kits now and people all seem to be loving them!

 

My poor SOS kit makes 318tq

 

I've had the Vortech kit, and a buddy had the SOS kit. Another customer of ours has Kraftwerks kit and it's the best by all I've seen. If your interested within, let us know.

 

I have tuned the following supercharger kits:
1. Kraftwerks (on several cars)- all made anywhere from 390-420 range depending on header and exhaust.
2. SOS on two cars - made around 350
3. HKS on one car - made 360
4. Vortech - made 365

Out of all the kits I would personally buy the kraftwerks kit.

 

To be honest, those numbers don't really mean much. All depends on pulley size and out of the box power.

Swap the pulley and that's about it you're in a totally different power category
