if your not looking to upgrade then the KW kit will provide the most WHP of any bolt on s/c kit out of the box.

 

Yeah i just read the installation of a clutch. May as well wait and do the clutch and rearend first and then have the kit installed.

How many people are running the sos sport clutch (255wheel ft/lb or tq) This sounds like it would be right now the edge. What else would be good for a daily driver.

 

A stock S does that.

But I have to say being at about 350whp myself, it does the job nicely. I could make use of 400/450whp though, but my bank account cant. I'd like knowing I could hold my own against any exotic. Its in my nature to want to keep improving the car though so I would hate knowing that my kit was maxed right out of the box like the KW -- or over maxed from what it sounds like.

Also as far as the clutch, the ap2 PP has significantly less holding capacity then the early Ap1's 00-01. Not sure about 02-03 since I havent had the opportunity to use this yet. The ap2 also has a CDV which adds wear to the clutch, so keep this in mind,. I don’t know what year you have. If you go ahead and decide to do a clutch, don’t forget to put in a lightened flywheel, 8lb Findanza works awesome, been running the same one for ever on my N/A f20/ boosted f20 and now my boost f22, not only does it extend the life of your main bearings and free up additional response/hp, but also removed some of the duty from the friction plate effectively increasing grip force and extending clutch life. This is all stuff that seems to be debatable for a given application but I have experimented with over the years on my s2000 and can confirm.

The rear end isn’t necessary at the power you will be pushing, save your money. If you’re going to compete in drag racing every weekend then forget what I said.

 

The stock s does get up and go. Sometimes I can't believe that it takes 14 seconds to do the 1/4 mile.

I think at 350whp the car will be at the limits of drivabilty and road skating (melting the tires thru the gears).

I'm going to order this kit in the spring. Are their any know problems with the kit as of right now.

 

Actually 350whp sounds like allot, and compared to stock it is, but if your like most of us, after about a month you will have had the chance to run it through its paces and see where its weaknesses are and want more. At 350whp 1st gear is pretty useless without some nice sticky 255's. But by no means is it too much for the street, if this is your idea then you may be disappointed when you find out you cant upgrade your KW and have to sell it like some guys have. Just food for thought.

About 450whp SC is when you start really running into traction issues in the first 3 gears, but sill nothing that couldn’t be helped with some fatter sticky tires. You should talk to Sideways about his 475whp Vortech set up and see what his impressions are. I think he still only runs 255's. Turbo is a bit different animal, since more trq is made at a much lower rpm, breaking traction is more of an issue. SC is way more tractable overall, however with an SC, since it builds more power as rpms climb, once you do get in a situation where you start to break the tires lose, it will just keep spinning more and more so it can be a bit harry, whether as a v8 or turbo hits a flat line in trq curve and may just maintain a consistent loss of traction. Just breaking it down for you so you know better what to expect hahaha

 

Thanks for the info. This will be my first supercharged car so it is a whole different animal like you said. You gave me some information to think about, but I still think that I will go with this kit. I want something that has reliablity and once I start upgrading most of that is out the window anyways. From reading around 400whp is the breaking point. That is the breaking point of my bank account. So this should be good. If I want a drag car I'll go with a different chassis. Maybe a 70 chevelle. I appreiate all the info though.

 

 

My Khumo Ecsta MXCs hold 350 excellent. I get some wheelspin up top in first and a tad from first to second. Too bad they are discontinued.

 

3.6 came standard, I got the 3.4 after the fact. I probably should have gone with 3.2...I have quite the pulley collection going right now.

 

[QUOTE=Mother,Nov 12 2009, 07:36 AM] Graves, what year is your car?

If it's 06+, then any price difference between the SOS and the KW is quickly eaten up by additional mods or add ons needed for the sos to make the same power as the KW. (The 364.8 hp dyno on the SOS site is made with a $1500 J's header and a $1300 T1R exhaust).

If you read the D Sport article, even with the SOS making more peak power they still liked the KW better during the track test.
