Aftercooler question about air pump
Im installing an aftercooler after getting rid of my FMIC set up and I have a question about the aftercooler connections. I have the air pump line removed and have a small K&N on the output of the air pump. Now on the aftercooler where that line would go I was planing to use a bypass cap. Is this ok? Does this hole suck or blow on the aftercooler. IM asking beucase if it sucks its fine but if it blows I think 11psi may push it off so maybe I should get that welded shut. Any advfise would be great
Thanks

Just put a cap on it...might want to use a clamp as well. Just out of curiosity...why ditch the FMIC?
Fmic's are not a good setup to run for sc s2000's. 3-4 psi boost loss is common plus much worse throttle response.

I've had both setups: the ct aftercooler with cobra pump and larger heat exchanger and also an authentic UR front mount intercooler set.
Both were with the ct blackbox, fuel regulator and Fb 340lph.
I didn't have a boost guage to measure the amount of boost for each, but a 4" pulley would get me a 12:5afr at redlinefor the aftercooler setup and a 3.8" pulley for the intercooler would do the same.
I believe I had more peak power with the intercooler. It was also easier to install and much simpler. During the summer I experienced no heat bog.
The aftercooler setup gave me better throttle response, but nothing significant. I did feel the power loss though.
Unless you are trying to max out the supercharger, i don't see why the intercooler is a bad option.

With a properly setup aftercooler/heat exchanger iats should stay pretty low. While driving mine usually don't go over 120 when 90+ outside.
Throttle response is a lot worse due to all the intercooler piping.
Fmic might work if your target boost is no more than 10 psi. To get that you would have to run a 12-14 psi pulley. 2.5-4 psi loss is normal for a fmic setup.
So if you want 12 psi with a fmic you will be overall ning the blower and making a lot less power since it will be blowing hot air.
