scalbert,... good call on "http://www.obd-2.com", it's almost half the cost and will show as much as Autotap because it also only shows OBDII mandated values.

if i missed or repeated anything tell me cuz i didn't read everything...but like you guys said comptech never advertised their boost amount. They said their S/C was probably gonna run about 5.5 lbs of boost and give about 310 to the wheels. If scalberts calc. are correct and he's running 4.41(or the accord) then comptech was pretty much in the ballpark. Besides given the higher compression ratio on the Type S (10.5:1) wouldn't you want the boost to stay low. I mean im' sure you can put 6lbs and not worry about frying a ring or detonating or somethin, and i dont know if i missed this but scalbert what is your air fuel ratio around? i thought maybe for a supercharged engine like allmotor was saying you figure you'd want around 14 so this way you reduce the risk of detonation(even though this could happen at any point without forced induction if i'm not mistaken, that just ups the risk). well i'm done blabbing, just curious though

Well, I just spoke to Shad at Comptech and discussed this matter. The official boost pressure is 3.0 - 3.5 PSI on the CL-S6. So I am right in the specified range. The original kit was pushing mid 4s but they found that by backing off they made the same or more power.
They suspect that in other regions such as mine, higher boost could be run for more power. So the higher boost pulley will be on the agenda for me.
As it turns out, I am running right where I should be.
I still want to try out a suggestion which Jens had about the IAB valve since I am running a lower temp stat, but that is later.

?? Better fuel quality, elevation,....??

The IAB is the intake air bypass, it is used during cold starts to supply additional air at the injectors. This is supposed to help cold atomization. However, I am running a cold T-Stat and Fan Switch so the IAB might not be closing all of the way. If not it would be dumping some boost back into the intake.

Steve. I saw similiar results where the performance gain from an incremental raise in boost pressure... say 3.5psi to 4.5psi is hardly noticeable. However.. 3.5psi vs. 6.5psi, is a noticeable gain. In terms of power output... pressure-aside, the volume of air forced into the motor plays a role as well. The Comptech blower is a pretty big unit and pushes a pretty large amount of air for a given pressure. One of the things I regret about my turbo kit was that I couldn't use the GT35 turbo... it would have probably made more power at the 5.5psi than the T3/T4... ah well!

Actually the blower used by Comptech is almost too small for our application. I would have prefered the M90 instead. But the M62 works fine for this application at lower boost levels. It would also keep the costs lower since the same blower is shared with other products.

Hey Jens, I isolated the IAB but did not bring home the calibration gauge. I'll try to re-test in the next few days.
Got any good recomendations for one way valves?? I'd like to isolate the EVAP system also as you mentioned. Thanks...

I was going to put a one-way valve in-line with the EVAP. I was tee'ing my boost-guage from that line, so every now and then during idle it would 'blip'! A one-way should prevent that!
Have you installed your springs yet?

Scalbert I will in the course of today into tomorrow make up a list of the various oneway valves I used to accomplish what I did in the Miata.Allow some time I have to install a VORTECH supercharger into an S2000 today and that is eating all my time .Thanks ,Jens

Higher boost would make more power provided there is no knock. But with a little pinging the ECU will back off timing to a point to where power could below the lower boost output.

It is ironic how I planned on doing the springs first and ended up slapping on the blower.

hey scalbert why am i getting steady 5psi on boost with my auto meter guage hooked up directly to the blower vaccum line and the throttle body i teed it in.and jens used a vaccum guage at work and got same results.what do you think why im getting more boost and could that be why what were talking about the past few days is happening?
