8 psi made 400 whps??

r u sure? or is it on Church's dyno??
as for SOS dyno graph, u can visit sos website.
Theres an entire build thread on the car. that was dynojet numbers on a very conservative dynojet. highest HP KW car thus far.

since when does a KW car run 8psi? hi boost kit was 9.5-10psi and low boost was 5 or 6

Ported head and big exhaust changes the boost #'s

i'm pretty sure they're instant if you're talking about a throttle response lag like turbo spool-up. but the boost is linear on a centrifugal, so at 4k rpm you only have half the boost you get at 8k. with roots you get it all early on, so you have a lot more power in the mid-range.

what do you mean? centrifugal superchargers have reduced boost at low RPM as boost is a roughly linear function of RPM. they also have some parasitic drag that drives the belt similar to having the AC on. but they don't have a spool-up lag like a turbo while exhaust pressure builds the boost from zero to max. did you miss my meaning, or am i off base on something fundamental there?

plz post link.... because i saw one of the thread about 400+ whps while back... prove to me that's was only 8 psi..

it was 8psi. psi is a measure of pressure, not volume. if the motor is more efficient, the measured "boost" will be less than before, even if the power figure goes up.

heres the thread, pretty old now.

https://www.s2ki.com/forums/index.php?showtopic=644509

Few things changed on the car as it evolved. Fcon and the 04 ecu didnt agree on idle strategy. SO jack and mase had a talk and the car ended up with aem ems on it. Jack can chime in as to the final numbers. The peak power wasnt much more 412 or so, but endyn head, 95mm pulley and vtec coming in earlier netted him like 50 or 60 more in the midrange.
Car was sweet before the water pump pulley bailed. Now its getting taken to the next level.

Leo, you have posted your dyno sheet twice already. We got the point

Ok, so why are you guys posting numbers to impress this guy on HIGHLY modified S2000s (Head work). I think in his situation he is looking for "bolt on" power.

To the OP. its nearly impossible to ever be satisfied with the low end torque on a honda. I'm not sure how mechanically inclined you are, but for the "average" enthusiast a centrifical charger would be ideal in my eyes. Every kit has it pros and cons. Seeing as power is all your after and if your willing to sacrifice the ease of working on your car, and modifying your car to make a kit work, id get the SOT kit. I'm not bashing the kit, but I have read a few threads about each kit and have come to the conclusion that the SOT and kraftwerks kits are problematic. The centrifical kits (COMPTECH/CT-Engineering, Science of Speed, and VORTEC) are the most basic kits. I have personal experience with the COMPTECH and SOS kits and I must say I'm very impressed with the ease of installation. The SOS is by far better than the older COMPTECH kits. You can swap out pulleys without unbolting the charger, overall its the best bang for buck. Just looking at the kraftwerk kit and thinking about working on it makes my head hurt. However, it does turn very impressive numbers.

My biggest advice is for you to get an AP2 with a 2.2L, especially because you want more torque.
