haha thank you. I just picked up a PRB ecu and im getting ready to do Kpro next year. Just got a COMPTECH catback as well.

 

i should be expecting delivery sometime this week

 

maybe you can do a boost leak test to see where you are losing your psi.???

 

UR claimed their FMIC is for high boost set ups, so ill put it up to the test

most everyone that has tested this FMIC was with stock/low boost. im at 13psi

 

hope you get it figure it out

USDM EG, Sorry to hear about your low boost problem with Comptech Supercharger and aftercooler. I noticed that you had checked your supercharger belt tension and were able to rotate the belt 180 deg.; that is too much! Your SC belt is too loose. I have a CT SC & AC on my '02 S (AP1) for a year and half now. Comptech told me the quick way to check your supercharger belt tension is to rotate the belt with just thumb and one finger. Correct SC belt tension should be at 90 deg rotation.
I was losing some boost with the weak (plastic) OEM Honda PCV valve sometimes allowing boost pressure to leak past. Since the Honda S2000 PCV valve has a 90 deg bend, I was unable to find a stronger all metal valve to replace it. So, I bought a Toyota Supra Turbo PCV (straight/all metal) valve and inserted it in the stock Honda PCV valve hose. My S now has two PCV valves and no boost is lost through that vacuum hose! My Comptech Supercharger is now running the (AP2) 7 psi pulley. At 8,800 rpm, I am getting 6.8 psi at the intake manifold and dyno 295 rwhp. I am running the stock exhaust system, but could expect to get 15 rwhp more with a test pipe and Comptech catback exhaust system. It is my understanding that any boost higher than 7.5 psi requires an AEM EMS and other mods on the Honda S2000 engine. If your clutch is slipping, you won't get a accurate dyno reading. Also, my S was running too lean after the supercharger was installed. My tuner had to adjust the Comptech SC kit's fuel pressure regulator to richen up the mixture with the (AP1) 6 psi pulley and again when the (AP2) 7 psi pulley was installed. I hope this information helps....good luck.

thank you! Im actually going to be doing a trans flush and oil change on it today. So ill adjust the belt. I am also going to be having my car dynoed at King Motorsports to see what I can get on a non mustang dyno. I have a spare OEM honda PCV valve laying around that im going to install, hopefully taht will work, because I too also noticed i was leaking out the PCV.

thanks for the advise!

 

i installed the UR FMIC a couple weeks ago and it works great.

the power of the car feels the same. i do not feel any power loss. i havent dynoed the car yet but am happy with my purchase.

it looks great too

 

USDM EG, I am sure that you know the S2000 PCV valve is designed to allow the engine's intake manifold to pull a vacuum from under the cam cover thus sucking engine crankcase vapors into the intake manifold to be burned in the combustion process (reduces air pollution and releases crankcase pressure). The S2000 OEM PCV valve was not designed to withstand positive pressure (going opposite direction under forced induction) from the intake manifold. That is why I chose a PCV valve designed for a turbo engine to install in my FI S2k PCV vacuum hose. Since PCV valves are one-way valves, it is important that they are installed correctly to allow the intake manifiold to pull vapors from the engine and not block that flow (installed backwards).
I look forward to seeing your new dyno numbers! They should be HIGHER with the correct tension on the supercharger belt.
