That is a good question. Do you have any friends with a TIG welder?

 

I thought this was a good question.

 

I think boost would start building a little later in the rpms if you use a huge IC . But a drop in boost ? I wouldnt think so...could be wrong

 

why do you want a bigger intercooler? Are you running air to air, water to air? How much PSI you running? Whats your intake temp?

 

Well i am running an Ar to air and prob going to be running 13-15 pounds and last time i got my car tuned the intake temps were getting real HOT i dont rememeber exactly how hot..... so I'm thinking of upgrading to a little bigger front mount!!

 

Instead of the bigger intercooler, go with water/meth injection. You won't regret it. You will spend alot of money on a new intercooler and temperature drop with be negligable. Just my opinion.

 

was just going to recommend that... good advice.

 

I thought about that to but i also want the look of the bigger intercooler and it would prob be bout the same price no matter what road i went down.

 

...but your gains would be x1000 better with the injection.

 

This is also true HAHAHAHA!!! good argument!!

 

Again, as I have said before in many other threads, cross flow cores will generally be less effecient than a vertical flow core with the same width.

Obviously for kits like the Greddy you need a cross flow due to the end tank configuration.

It is better to have more shorter rows than fewer longer rows because you spread there air out more among more surface area with a greater temperature differential.

With this in mind, bigger an thicker is not always better.

Vortechs orginial design, IMO, was better than their current design for the intercooler. All except the fact that I believe the inlet tank was not baffled to equally distribute air.

The longer that air has to stay in the core the more pressure drop you will have and in the case of longer rows. With a longer row, the majority of the air cooling is done in the first few inches where the temperature differential is the highest. After those few inches you are getting less and less out of the row than you could be.

Now I am not saying that a cross flow doesn't work because obviously they do. Most kits come with them because either they need the configuration or because most people find cross flow to be more appealing.

Just something to consider.

 

+1 on Bell Intercoolers. A couple guys in my crew have had custom intercoolers built by them.

 

Corky Bell and Gerhard have excellent knowledge and great service. They will both be willing to help you design an intercooler to meet your needs. One of the nice things is that say your end tank that you spec out is a tad to big. You can just send it back to them and they will fix it for you. They actually do maintenance.

We just sent our 928 air/water intercooler in and had the inlet/outlet cut off and new bead rolled ones welded back on. Excellent turnaround time and since all they do is custom they seem to be right up your alley.

 

There are a lot of companies out there that make quality generic bolt on intercoolers, and will even customize end tanks and core sizes to meet your needs. For my own car I just went with a Spearco universal intercooler (largest they make), but they also make them to order if you contact them directly through a dealer.

And, well, I personally would up the intercooler before running water/meth to compensate. Sure you could make some great gains with the water/meth, but if you ran out of methanol for whatever reason it would kind of suck. You'll never run out of air. There are also other efficiency considerations like the inlet/outlet sizes on the end tanks... Just something to think about.

Oh, and Vortech sources the intercoolers from their kits to Spearco, which is the intercooler manufacturing division of Turbonetics.

 

That is the argument most people have against Water/meth injection and I understand it isn't totally convenient. With a decent size tank you have to fill it up for every 3-5 times you fill up your gas tank. You do remember to fill up your gas tank right? If you tune for smurf pi$$ then you can get it at just about any auto parts store. Some people just don't like the idea of water/meth injection and I get that. It's just one more thing to worry about but anytime you have a FI car you are constantly worrying about little things.

 

I had to think about that one for a moment. Very Funny. The hard part about "smurf ****" is that it is very difficult ot get the high methanol content stuff in the southernmost states. The lowest I have seen if Florida is +20 degrees F (10% methanol contect). The good stuff is the -30 degree F stuff (36% methanol)! And in spring, summer, and fall, you be lucky to find the 32 degree fluid (which has no methanol content.)....IF you are really lucky (live somewhere really cold!) you can get -45C (-49F) fluid.....that has about 62% meth content!

 

If you're still running the SC-Trim upgrade to an SI or T-Trim. You wont be spinning either close to its max like the SC and the temps should drop. The SPEARCO that comes in the kit is good for about 500RWHP. I would only swap it out for a bigger one if it has become restrictive. If you go with a bigger cooler core you'll lose some boost, which means you'll most likely re-pulley the blower to make up for it, which means you'll have to spin it even harder, which means you'll be generating more heat. Correct me if I'm wrong.

 

Well im not going to be going drastically big just enough to drop them intake temps a lil..... i say that becuase last time i got my car tuned my intake temps were getting pretty warm in the upper rpms and all i have on was a 2.87!!!

 

tuned on a dyno using a fan that prolly doesnt come close to replicating real world cooling conditions????

 

Does anyone think that this intercooler would work? http://cgi.ebay.com/ebaymotors/FMIC-...em350014384651
Dimensions are 30 x 7.5 x 3 They also have one that is 30 x 10 x 3
