Hey guys I'm planing on getting a Comptech SC and I saw this on ebay. And i want to know if this is better then the aftercooler or what looks really good the air temp is really low and will sound great. Has anyone done this and if u did can u give us a feedback. Thanx a lot

Sounds like the air to air may work better. Comptech has a very small heat exchanger to cool the water. If they ran the car a lot and heat soaked the water I can see why there is such a big difference.

It should cost less to have someone build the same thing for you. Much less that 1k shipped.

 

It will more than likely be more efficient than the Comtech aftercooler? I've never put my eyes on the heat exchanger core though. Intercoolers and Aftercoolers can only get as cold as the ambient air. I always preferred the look of an Aftercooler in an S2K which is why I'm going the route I am.

If you like the look of a FMIC then have at it. People have experienced a pressure drop using Intercoolers which is likely. I would suggest a 9lb pulley with a FMIC, you would possibly be looking at around 8-8.5psi.

You can get a larger heat exchanger core for your Aftercooler though, they sell them on Vortechs site and I'm sure a butt load of other sites. I haven't looked. I personally will be using the stock heat exchanger core that comes with the Vortech kit. It's very efficient and I can tolerate it with my day to day driving and it can tolerate me as well.

 

Not worth the pressure loss IMHO. If you want your car to look like its turbo charged then put a turbo on it also my opinion.

 

^^ Your opinion but I feel like that is quite an ignorant statement.

Less pressure but cooler air which makes more power and you can always compensate with a a new pully. This piece has been spoken about extensively in this forum and it looks very promising. I am just waiting to see someone with hard numbers before I take the plunge.

 

Idiot comment.

You get pressure loss with a turbo also. It's a universal scenario. Just because it's a SC does not mean a Intercooler is not meant for it. Stop posting if you don't know what you are talking about. Your useless information should not leave your fingers. Your opinion and IMHO is not valid. Stop polluting this forum with you uselessness uneducated comments.

Most big time drag cars that are turbo'd run Aftercoolers fyi. In most cases it's better to run an Aftercooler. So many scenarios make so many differences. IMHO!

 

There was a thread on here about this and a guy did an actual test on the dyno with pressure drops and the difference was .5 psi drop going to the UR FMIC kit from the aftercooler. But there were significant charge temperature drops using the FMIC kit rather than the aftercooler. They advertise 75.3*F drop at redline with the FMIC kit against the aftercooler.

 

drag cars also only run the strip ONCE......
I'm sure you could use a liquid nitrogen in a water to air exchanger and pull air temps that would be ungodly low and make massive horsepower, ONCE. Hell you could probably pack your air box with some dry Ice chips and lower temps... ONCE.
What I'm getting at is the aftercooler can become saturated after some driving and then looses efficiency. I've seen the test and I'm not trying to knock aftercoolers, but the saturation is at least something to consider. Air to Air has its own problems as well of course.

Full on TOP fuel drags don't have radiators either....... but I wouldn't suggest that.

Also I'd take a large temp drop with a .5 psi drop ANY DAY. It doesn't take that many degrees POST compressor side to make a huge difference in power, def can be enough to make up the .5 psi drop that's for certain. DEF 75*F drop!

Think of a cold morning vs a hot afternoon, I'd weigh that alone very heavily against .5psi.


This is just IMHO though

 

Mino8123.... don't feel like it's your fault when you hear on the news someone was shot and killed in their home due to a big argument on a internet forum about aftercoolers vs intercoolers.

Hope are arguing has really brought you the answers you needed haha!

oh another thing to consider is that intercoolers only work when air passes through them (I don't have fans on mine) so that means only when your moving 30mph or so does it become efficient. *35mph* is a number I pulled outa my ass of course, I've found thats when people say the fans on radiators do less work then the wind in general, so I figure its a good estimate for an intercooler as well. Also remember if you want the low charge temps of a non-heat soaked aftercooler then you can always try spraying your FMIC. There's a few options out there to give you a few pulls with extra low temps.

****** Has anyone upgraded their FMIC in a big way size wise to see hp increases?*****

I've been thinking about it and its a rather small core, I wonder how much I could help my HP numbers out. Certainly if the flow was better and the temp was lower I'd see an increase.

 

Or you could get a front mount radiator and have lower temp+no boost loss+front mount look. And for less than half the price.

And by the way, on a cool night, after running the car hard, I can put my hand on the aftercooler and it will be very cold compared to the rest of the engine and the SC.
