Well for one would be the throttle response. Lose pressure but running a smaller pulley can compensate for that. Also wouldn't the sc been spinning faster for less psi causing more wear on it?
I'll try to dig up the heat exchanger I bought on ebay.

 

Also if you ever wanted to run say 12 lbs wouldn't you have to over spin the sc to get that since you would be losing a couple psi with the fmic?

 

The faster you spin your blower the more heat it produces which means higher AIT. The fmic can more then account for this as its cooling is efficient, but the boost loss sucks and I am not a proponent of spinning a blower faster to compensate. This certainly sucks if you ever want to maximize your blower later and make over 9-10psi. Aftercoolers are more efficient with SC's for this reason. And with an upgraded heat exchanger its debatable if the fmic would cool any better anyway.

I run my stock aftercooler/heat exchanger with 9psi no problems.

I guess your going more for the looks though I forgot.

 

ok so i guess i should get the fmic idea outa my head lol

 

Fuelly is simply a gas mileage website. I monitor my driving on my two cars.

The SOS kit is specifically for SC kits like the vortec, SOS and comptech kits. I had an UR FMIC. Its a WASTE of money. The quality was...ok. Fitment was an issue too. I lost 3-4 psi with that kit and I was overall not impressed. Im pretty picky though.

 

I am running an UR FMIC and I am very happy with it. It keeps the temps constantly cool on the track which can't be said about some of the after coolers. I have not seen the results of the SoS giant heat exchanger though. The aftercooler plus heat exchanger is also a lot more complex then a front mount, more things to go wrong. I am running a 4.0" pulley and getting 5-6 psi with my FMIC and comptech NOVI 1000. Throttle response is still good and it works well. The NOVI 1000 is also rated to 55k rpms if I remember correctly you would need like 3.2-3.0" pulley to overspin it.

There is a lot of hate on the front mounts because they aren't as efficient, but it's a solution that works very well for me.

 

got any pics of the ur fmic installed?

 

It works for you becuase your happy with 5-6psi.

 

It's a toss-up between both. Intercoolers are almost maintenance free while watercoolers need more attention. Watercooler in sc give more psi per pulley and better trottle response for lower psi's they are better. Front intercoolers should be more consistent in power than water intercoolers as the waterIC usually sits in the engine compartment gets heat soaked quickly. How many turbo kits run water intercoolers? Put a precision or spearco up front and you can run more timing than watercoolers that get heatsoaked. With front IC you loose .5-2psi of boost depending on pulley but allows you to run more timing in higher boost settings offsetting the pressure drop. For running 5psi of boost might as well put a elbow tube as there's not much heat there.

 

I'm intercooled 8psi and run close to 350whp SAE. But I acknowledge that a water IC provides more boost at the same pulley size but dont think it will provide more power reliably per pulley size as with front IC.
