A Front Mount Intercooler will increase output?
I'm only running 6-8PSI and and wondering if an FMIC is even worth it.

How much boost is needed before...

mmmmm ... turbo
if your turbo is adding heat to your intake charge, a QUALITY fmic WILL add power
the best way to figure out if a front month is worth it is to simply check your IAT readings
-1% HP per 10 degree temperature increase
+1% HP per 10 degree temperature decrease

Does s/c and turbo make a difference with intake tempartures??? I would think A turbo would produce hotter charge temps since its compressing the air AND the exaust is running so close to it. unlike a blower which is just compressing the air.
SHOshop ran the 12 psi kit with no charge cooling (15psi too). I would say 12 would be the max though w/out some kind of charge cooling. Anyways the colder the better.

Depends on the turbo or S/C setup, but the air temp raises dramatically and exponentially as you reach the efficiency limit of the setup.
For example, the temp between between 6-8 psi boost is much less than between 12-14 psi. It's not a linear scale.
On my SHOShop setup, the air temps (before aftercooler) really start getting insane at 15psi. I feel that's the efficiency limit of my setup, which includes the Vortech S-Trim, and the intake piping.
Sure I can get even more boost past 15psi, but I feel you get less return for investment and safety
Will 12psi setup work without intercooler? Sure. But it's not too smart IMO.
Having an intercooler, even at low boost levels, really increases the overall reliability of the motor. Plus you will always have room to boost more!

Ive known/know plenty of people running ebay intercoolers on some pretty high horsepower setups. I'm not talking 600-800hp im talking 300-450whp. Even still, they've yet to have any problems, i think one guy with a high dollar s2000 had the welds bust on one but he was running alot of boost and ive yet to see it again.
Heck i live in a small town and i can find a good shape used FMIC for fifty bucks, at, the very worst they're brand new on ebay for 100. At that price, i dont see why you wouldn't.

I personally wouldn't run a turbo without an intercooler, but thats just me. I'm sure you could get away with around 6-7 psi without one. With a supercharger, I know people that run up to 12 without them. And they havn't blown there engines yet. However they might not be making as much power as they could with one.

Gas is $$ WALK!
I've seen plenty of cracked pistons on the SC cars that do not run charge cooling.
I do not run an intercooler, but I don't have the room with my massive oil cooler. I do run water injection and have been happy overall with it. It takes a little more tuning as to boost/fuel/water/timing mix, but it can really make a huge difference.
With 6 PSI, a good tune and STREET driving you'll be fine for the most part. Hot days and long runs would yeild caution on 6-8 PSI.
Turbo's and SC's that compress air are FAR more efficient than a roots blower. The heat output from a roots blower is tremendous when compared to the boost levels they push.

I didn't know that. But I have talked to people that are running the sho shop 12 pound blower (thats what I was told by the guys brother) without an intercooler. He never had a problem. But now I am informed that you can break pistons. Thanks YamahaSHO.
You can break them VERY easily in fact. PanamaPat had a total of 3 pistons cracked on two separate occasions. If the SHO Shop tune is used, it's almost a wonder why they don't break sooner.

Liquid to air cooler?

A vortech after charger would feel right at home with his setup. Not really that big and he could mount his heat exchanger up front. I plan to go to a water to air over the winter.
