Don't like you Spearco IC anymore? I guess one of the benefit of a bigger fmic is the efficiency of handling high boost.

Colder intake temp= more HP. nuff said. Is it going to be water-to-air or just air-air?

Just look into water-to-air, you will thank me if you get it, their is no campasison between the two, water to air is better period.

This is firsthand info. My brother had a typhoon. 4.6 ltr turbocharged gmc blazer. It had a water to air aftercooler on it, and driving only 45 minutes would heat soak the aftercooler so bad you almost couldn't touch it. When we went to the track he would have to let it sit for at least an hour with water and ice in it to cool it down. The only reason, you would want a water to air is for drag racing only. that is it.

i agree, i would stick to air to air if its a daily driven car. I have the type 24 intercooler from greddy and i love it. its huge. personally my engine doesn't really need it because i am only running around 8 psi, if you are running more than 10 get the big one and it will help you out more than the spearco one because the lines are thicker on the greddy one. its nice and shinny too! expencive though, but if that doesn't matter go for it, but only if your running more than 10 psi

Did your brother have a seprate radiator for his aftercooler, or did he just share the water supply with the cars radiator. If they are only for drag racing how come some Subaru's come with them stock. Air to Air aftercoolers are only effective at high speeds, and I am not saying that they suck, I am just saying water to air are more effecitive.

if the ic is too big for the turbo you will loose power, and efficiency, because of loss of pressure etc.... i heard it somewhere, i would do some research on it before buying the biggest one greddy has to offer.

You are right BoostedRex, if the aftercooler is too big it results in power loss, so get one in accordenc to the amount of boost you are running.

i am running at 13lbs right now daily driven??would it benefit me?

bmilescrx · 06-02-2002, 02:50 PM

you all have forgot a very important piece of the puzzle, Its not just about how much boost you run, but about how much air flow you run, i.c. sizing is based on air flow requirements, not just psi ratings.

your best bet is to look up on a compressor map for the turbo you have and find the flow rating for the psi your running , and then calculate how much air your compressor can run, then with that number you can find out how much (theoridical) hp you are making.

roughly 1 lb of air =10hp so if you compressor can run 30lbs of air @ 15psi of boost you would want to buy a ic that is rated for roughly 300hp , granted you are not running that much air (more like (22lbs of air @10psi) but its much better to have to big of i.c. than too little of an i.c..(within reason)

I have personally gave myself about 100hp buffer on intercooler sizing, it give you alittle room for future upgrades and will prevent heat soak from comming on too quick. however if your turbo will run 40lbs of air and your currently running 20lbs of air and have no intent on running 40lbs, my recomendation is to get an i.c. that is good for 30lbs of air/or (300hp). you get the idea just do the math and youll be all right

good luck
