Default New intercooler to replace A&A

For all you fine gents that are smarter than I. I'm looking to find a intercooler to replace my current A&A one. Its a great i/c, but I can't help but think something with a little more capability will help me out some.

Does anyone know exactly what my current i/c is rated to cfm wise?

Where would I go to find a better replacement? I'm also not worried about inlet and outlet sizes as I am redoing all the piping and can step up if need be.

I'm not worried about engine temps as this thing runs really cool with my current radiator and fan settings, even in the OK heat.

Which A&A intercooler do you have? The first gen cooler? or the newer ram air cooler?

The A&A cooler flows enough to effeciently cool 1500 cfm. I think it does it's job really well.

It's the best comprimise between flow and cooling without losing too much psi through it.

What are your current IAT's now, with the existing A&A intercooler?

If you have not logged them under a good, hard 3rd to 4th gear pull, as Arun said, you may not gain anything by going bigger, other than increased pressure drop.

1500 is a solid number, but a YSi at full tilt is 1,600cfm. I agree that it is a great compromise, but I'm looking to 86 as many compromises as I can.

On a 100* day I have logged IAT's at almost 170*. On a 80* day I see 150ish. Both of those numbers are w/out water/meth.

With the water/meth on: 100* I see 90* at the end of a long pull. Same on a 80* day. Can't get 'em below that.

If you at those temps with the meth I would even change it buddy. Not worth it. Give the V11 a little time to get done and then look to change out the system.

Those are pretty good temps-mine are around 30-40 degrees higher.

Your not spinning that blower fast enough!

Send a PM to 4DRUSH or Digivex, they are moving on from A/A and have our std intercooler and cradle. It's frame rail to frame rail. Of course we have them in stock new, but it's not like they are a wear item so if you can find it used...

Kidding, If I remember correctly (please dont shoot me if it's not exactly correct) but I think it's 28" long-3.5 thick-8-9" tall core, with a US made high flow core. There is a big difference in who/where the cores are made as far as flow goes, so dont just go by size of the cooler.

My new A/A intercooler is 4.5" thick and flows 2400CFM. I hope to have my car back together by next month. It's at the body shop now getting some cleanup work.

If I didn't have the tigershark nose, making it possible for me to cut the bumper some and move the intercooler way up front, I wouldn't be doing such a thick piece, but I feel like (and hope) this will be the ticket.

I'll report back my findings when I get it all going.

Let us know, I have found going to thick on the core reduces the flow threw it so it will be interesting to see.

I plan on also testing the A/A theory I have of being useless after a certain boost number. I think we talked about this if I remember correctly, I'll let you know what I find on that too.

I was looking more for the rated CFM of the unit. I'm not worried about the size of the cooler, I want something with low psi drop and rated to around 2,000cfm for when I upgrade later.

Brett, PM me or give me a shout about your new one whenever you have time. I didn't know you had it done already.

I agree with JMBLOWNWS6, keep spraying the meth!
Those are really good IAT's.

I can understand the desire to go bigger to handle your potential upgrades, though.
Good luck, man!
