this kit doesn't make much sense to me. id rather get a used vortech/comptech kit if I'm going for lower power or get a sos/kw. The price isn't that cheap. it comes out to like $5600.

 

should ask speedfreaks on what they can get for you as well. they're a sponsor on here

 

I looked into this SC a little while back, maybe in 2013. Basically some of the shops selling this kit said more support would come out later to provide more power but from the info in this thread, that hasn't happened lol. You're better off getting something with better support and kits that are regularly discussed on the forums in case you run into problems.

Also Vader brings up some important concerns.

As far as foreign transaction fees, I love my Capital One Quicksilver card for overseas travel and shopping :-) You get amazing exchange rates and 0 fees.

 

I have been looking into this kit as well. From what I understand you will get about 350 HP and 240ft out of this kit. (the 400 hp in the vids is at the crank and there has been some UK guys putting down these numbers with the high boost pully) Not to bad and has proved itself on the track. It obvously depends on your end goals, and how much time you have to mess with issues like the KW kit is having. I looked into a few suppliers and it looks like they are telling me I can get the kit to my door for $3,200 right now. ($2,800 for the kit $400 for fees and shipping) Of course you need fuel and ECM but you would on the other kits I am looking at as well so just cancel that out. Looked at the SOS kit today and you are sitting about $1,300 - $1,700 cheeper for this kit depending on the options you get on the SOS. Studied a few dyno graphs and the SOS obvously has much more power but you are running much more boost as well. The SOS kit has more power, but then I need to start dealing with things like Diffs and Tranny's and grip etc. I guess my point is, that $3,000 bucks for a reliable kit backed by a company like HKS is an undeniable good value right now. If your goal is 400-500 HP period, then you would not even consider it, but I am still trying to figure out what I want my car to be in the end..... Decisions Decisions.....

I have a 350 whp 300 ft pound SRT-4 and it is pretty quick for me. The thing I learned is we keep making our cars faster and faster yet the dynamics and demensions fo the streets where we drive them do not change. So there is a point, for me, that it just becomes "too much" if I dare say that. Unles of course you are doing freeway pulls which is a whole other story, but I hardly drive on the freeway myself. So how much is enough, and how much time do I want to be spending on my car. I intend to auto cross and would love a powerful reliable set up where all I need to worry about is tires and breaks..... LOL sounds like I am trying to talk myself into this kit. Anyway just some random thoughts.

 

So did anyone actually buy this kit? Anyone get to 400whp with stock engine? And it you bought it for $3400 and never installed it lmk, I'll give you $3500 for it

 

400whp is not possible, i myself on my uk car have 331whp, another guy has 322, and a third guy was somewhere between, that's with the supercharger on a car with decat and exhaust.

 

i believe there is a smaller pulley available, no idea how much of an increase in boost its suppose to give or what rpm you can run the engine too in order not to over spin the charger. We also know the dynos over the pond tend to read high!

 

from what i have read the 9krpm is right at the limit of over spinning the charger on standard pulley, so i think if you run the smaller pulley you are either going to have a much lower rev limit <8k? or face probable reduced life of the charger itself

 

my kit came with all the brackets for fitting to both LHD and RHD so i would assume they would be the same everywhere

 

You may be right but there must be a reason they sell a smaller pulley unless its just for the F22 Boys.

Id be interested to know what the power delivery would be like if the boost built up earlier and was limited to 8k on our cars.
