Hey guys I mentioned this idea before and I tried to ask in the SRT-4 forums about effiency and they looked at me like wtf, shows how much they know. So anyways I know the stock POS intercooler sucks big. Now this guy got a giant front mount for his SRT-4 and has his stocker sitting there. He is willing to sell it to me for $150 and I can get a place to custom fit it for 100$ thats a total of 250$ for a good intercooler. Is it worth it, and how efficient or non-efficient is it?

The CFM requirements of the SRT-4 is probably quite a bit less than the FDs.

I say go for it, and let us know how it goes! At least it has to be better than factory.

Yea, do it! I wanna hear how good it is.

Just Do It...like Nike! Shoot, for 250, you can't go wrong..can't go away from stocker any cheaper.

Hey, I'm actually about to go outside and start installing one right now.

I happen to work for DaimlerChrysler and know some of the engineers that worked on that intercooler. They did extensive testing and cfd of the end tanks to make sure the pressure drop was very low.

As far as the cfm requirements for the SRT-4, the intercooler goes, srt-4s can make similar power levels as our cars using this intercooler.

Also, keep an eye on the srtforums site. Some people are finding out how good the stock srt-4 FMIC is because they are making less power with bigger, aftermarket ones.

Anyway, I figure it's got to be better than stock at the very least. And at 200 bucks or so vs. 500 or more for anything with a greddy, hks,.... name on it I think it's a deal.

Anyway, I'll take pics and let you guys know what happens.

do it, it has to be better than the stock one and its only 250. and if its not you can put the old one back on and you only lose 250 wich you can get back from ebay dummys easy. have fun

w00t, btw to those that said it flows less, how is that possible if the things are boosting 15lbs stock no?

maxcooper

Size isn't the only thing that matters, but I am just curious. How big is the core (not including the end tanks) of the SRT-4 IC?

ALOT bigger than ours, check it out in the pic if you can see it. GOt it from the Dodge site.

skunks

it is bigger, i say go for it. also see if you can get his seats, teh stock seats are kick *** for a srt-4!

Isn't that just a grill showing?

ExpensiveHobby22

I just measured it. 24x5.75x3 inches.

So far, I've got everything taken off, and I'm fitting it. Looks like it will fit well. I'll post pics when I'm done working on it tonight.

thats fairly gianmorus should beable to fill up the front part of a stock bumper which is all that matters.

True you get looks and function.

I'm interested in the outcome of this as well. When is it supposed to be finised?

250 + piping/couplers is much cheaper than 900+ for a greddy if it peforms equally.

hyper 7....where'd you get that information from? Pretty much everything you need to know for doing some real calculations.

ExpensiveHobby22

My work schedule and whatnot will dictate when it's done unfortunately. I'll try to post some pics shortly of where it's at so far.

ExpensiveHobby22

I can't seem to post pics right now....

As you can see it sits a little low. That's because the end tanks interfere with the frame rails when it's fitted right behind where the fascia opening stops.

Also, I have the opening pulled open a bit more (note the bungee cord and battery)

I think I can manage to get it far enough to completely fill the opening. I'm not a fan of how it sits now. It might involve cutting the fascia some or the very end of the frame rails, neither of which I really want to do.

Also, note that the way I fitted the intercooler is the opposite way it is oriented in the one picture. The end tank with the turn up in that picture will be on the passenger side pointing down.

This picture and the one 10 minute or so promo video I've seen for this car are so ridiculous I don't even know where to begin.

Expensive Hobby: Let us know how it feels and what not, notice any differences? How is the effiency, maybe you want to check the boost at the turbos then at the manifold.

Pressure drop normally has very little to do with end tanks, it's normally a function of the internal passage size through the core. Core height and depth are the factors that matter most for pressure drop. Based on the dimensions posted "24x5.75x3 inches" I'd say it has significantly more pressure drop than most aftermarket IC's BUT, and an important BUT it is, I'm sure it's leaps and bounds above the OEM FD IC. If you can get it working for $250 then it's an awesome deal. It's not in the same ballpark as other aftermarket IC's though, even the greddy 2 row.
