I only saw a 1.25-1.5 psi loss when I went from aftercooler to a FMIC (AP1, 11psi pulley)

My IAT's went from 180-190 (AC) to 100-110 (FMIC)...well worth the slight loss of psi in my opinion.

 

WOW 180-190 IAT's!!!!! and you drove the car around? I only see ~100-120 at 22psi (over spinning the blower) with the SOS 2.5" thick racing Heat Exchanger.

 

Yeah something must have been wrong with your after cooler/heat exchanger for IAT's that high. I usually see 90-110 when it's around 80 degrees out. Highest I have ever seen is like 150 sitting in traffic in a super hot sunny day.

I did get an ebay heat exchanger and have had it for a couple of years now with great success. I contacted the seller I bought it from but unfortunately they no longer sold this one anymore as I had someone else looking to buy the same one I got.

 

sweet, good info from everyone, I will totally scope ebay for that heat exchanger over the next while

 

are you talking about this one?

I wish i knew the exact one to get or atleast the specs it should be.

 

Thank god someone asked this because I am on the verge of gettin a SOS sc setup but it comes with fmic only and I was curious as to how much of a difference it makes. Finding a ac setup for cheap is gonna be a pita now

 

yep thats the one I got but I bought it from here.

Thanks for the link! I will be using this to build my own little custom intake as well.

 

Check out my intake if you search my name for my upgrade thread and you will see my custom intake built using all parts from www.siliconeintakes.com you can get piping, tbolts, and a larger heat exchanger for cheap from them.

 

those water to air intercoolers they sell there look suspiciously simular to the ones that are provided int he vortech/comptech kits!!!!!!!
