So really in all rights the CT at 10psi with your current suporting mods would yeild very much the same power curve and numbers would it not?
just compare a KW @ 6psi to the Comptec @ 6psi and then KW makes 335 vs 300whp for the comptec.

I have seen plenty of 10psi comptecs with about 360hp but they had alot of supporting mods like exhaust, headers , test pipe etc, to help it get there.

...and in either case the comptec still wouldnt have the power under the curve, though a proper EMS could probably smooth out the vtec kick, there is no way a comptec could make 380+ whp by tuning with Kpro alone @ 10psi

I love your setup as I mentioned on s2katlanta, but I made 400rwhp/285rwtrq @ 11 psi WITH 9:1 compression

But yes, your setup is more efficient than most turbo setups that I've seen!

i know someone who made 370whp or so, 7psi, stock compression with his turbo!

the kraftwerks s/c is a very nice kit..

^very nice!!! I made 350 on 7 psi on my original turbo. It was a GT35 equivalent non ball bearing turbonetics turbo. But 370 is nuts - tell me they had a Full Race manifold and I'll rest safely I really want to get a Full Race tubular for my new RB25DET 240sx but they are over 2K

The Kraftwerks kit looks sicker every time I see it - If I had it to do over again I would have considered this kit in lieu of turbo but it was not out when I went turbo.

thinking about getting a Kraftwerks with exdey carbon clutch and 11 pound flywheel with a header J's or tracey and a S.O.S throttle body with a sard fuel pump and some denso 550cc injectors and ultimate e-manage to make some power along with my okada projects and my R1000 amuse

The CT setup was fun and after I sold it and was waiting on my KW setup, I really didn't enjoy driving it N/A. Even my 15 year old daughter said, "It's not the same, it doesn't give me that feeling in my stomach." With the CT it doesn't pull much down low but when the VTEC kicked in it felt like a 4 barrel opening up on a muscle car. It was fun to see peoples expression when it hit, but it really wasn't that much fun at the track if it happened to kick right while accelerating out of a turn. With the KW it just pulls hard and consitent right from the start. You can see why when you look at the dyno chart over-lay. In low rpms the torque from CT is not significantly more than stock, but the KW has more torque right out of the gate and with the K-pro tuning of the VTEC there is no kick. Adding a K-pro to a CT would smooth out the kick, but you're still not going to have the same pull at lower rpm.
I haven't really ridden in a properly running turbo car enough to comment on the differences. I do know that my car has a lot less under-hood heat, it's already tight trying to replace the stock header, let alone a turbo manifold, I've seen turbo setups where you have to relocate componets (battery, a/c lines, etc.) and I haven't seen any turbo numbers that come close to 382 hp on 10 psi.
Interesting analysis and I agree completely.

I still have the CT setup but I went with a higher boost setup and switched to the AEM EMS. I set my Vtec to engage at 4000 rpm but only under high load (ie. hard acceleration) to prevent destroying my fuel economy and needlessly taxing the motor.

The unusually low Vtec engagement rpm was necessary to completely smooth out the power curve...now you can barely feel when the cam switchover occurs which is nice because it doesn't have any affect on the car's balance during a long sweeper (unless I use my right foot to purposely do something fun)...

I won't lie, more power at lower rpm would be nice but the KW kit wasn't an option back in the day. The higher boost CT setup does provide a bit more power at lower rpm but nothing like what you must be feeling with the KW kit or a well setup turbo kit. I'm jealous!

Congrats on the excellent work and results!

PS - A buddy from back east had an Inline turbo setup make 370whp on Inline's dyno at 7 or 8 psi...his name was Chris and I'm sure he's reading this.

Yeah, there's no question about it. The Kraftwerks setup makes more power everywhere at the same boost pressures.

Now, the new Paxton SC that SOS is using appears to be a much better centrifugal option for us Comptech guys but I think KW has hit set the benchmark for what any supercharger setup can accomplish on this platform (outside of crazy builds like Sideways, etc...).

So it all comes down to the blower then, is that what I'm getting from this? Is the Kraftworks using something similar to the new 1200 Novi that I hear Comptech is replacing? The CT and Kraftworks are both centrifugal SC right? But the Kraftworks kit is using a more efficient blower or what?

The kraftwerks S/C would be more comparable to a GT30r than a Novi 1200.

KW uses a Rotrex supercharger which spins @ 100,000 rpms which is more inline with turbo than your typical Novi (50,000 rpms). However unlike a turbo the Rotrex runs MUCH cooler and IAT temps are typically shown to be withen 3 degrees of ambient, which allows more timing to be run = more power.

The Rotrex also uses a planetary Traction drive instead of gears so it runs more efficiently and is far less noisy. Thats why I called the Rotrex the "Stealth Bomber of Forced Induction"
