Hey everybody who answered: THANKS! I am going to look into some of the options suggested.

Anyone else?

As was said above, it's pretty much custom - depends how you want to route the blower pipes, what size, etc. Best bet is to mock something up (cardboard, etc.) and then match it up to an available core.

The other issue to consider that was just lightly touched on is the bar/plate vs. tube/fin design. I am far from an expert, but it looks to me like the bar/plate, for an equivalent core size, should give you lower temp (it's a more effecient design). It will also be *much* more resistant to damage from rocks, gravel, etc.

The downside is that it is normally heavier, and more expensive. Usually more expensive - I talked to griffin also - all their intercoolers are tube/fin, but they actually came in more expensive than a spearco unit for me, and other than the weight issue couldn't supply me with any technically valid reasons for going with the tube/fin style. Griffin does warranty their intercoolers for a year, and in regards to gravel damage, etc. they said (though I guess no officially?) that as long as I wasn't in a front end collision, etc. it would be covered.

That said unless weight is an issue (~1.5x the weight from the numbers I have seen) the bar/plate is definitely the way to go. (and that doesn't take into the fact that you can achieve the same cooling with a smaller bar/plate - which might bring the weight back in line - though I would preferr the maximum amount of cooling).

When mocking up you should also consider airflow to the radiator as well.

I'm picking up one of the intercoolers jordon mentioned above, with a few slight tweaks.

 

They don't really do F cars as their main business but give the guys at Indy Race Cores a call...I believe they still do a lot of custom fitting if I remember right, and they deal with guys running 25+ psi so I don't think that will be a problem

Thanks again! Good info.

Pics of an intercooler we helped design for Griffin:

That's about the biggest off the shelf air/air intercooler you can fit in our cars.

I think some folks were talking GP and the price was around $700.

 

Very nice. That's an off the shelf Griffin? Do you have a pn?

Not offhand, but email mbell@griffinrad.com to see what sort of pricing they have.

The engineer is jburns@griffinrad.com, and he has a LT1 Camaro so he's sympathetic to our cause.

 

I used to have a price list for Griffin cores, but it's old(6-8 months). I could send it to you if you'd like. It'll give you a rough idea on price.

 

Another option might be an intercooler chiller. They are becoming popular with DSM's. Basically you just run a shot of N2O through the intercooler. When I say through I dont mean on the inside I mean on the outside. They have kits that can be bought but they use N2O and it can be expensive. You can make your own out of old N20 parts or paintball parts. I would use C02 instead in N2O alot cheaper to refill. I like these because they are not as complex as an air-to-water and they are only on when you want them to be. Could be a cheap alternative.

An intercoopler spray bar is by far the best thing u could do for your air to air intercooler. Almost all the rally cars use them, the new Subaru STi uses one and countless others on the street.
I have one installed on my Dodge Daytona and it works well.

Now dont use N2O its way to expensive to do that. Either use a CO2 like boostedinaz said or use a water spray bar.

Basically its a simple system you just need to be able to mount the coolant somewhere. Have the spray bar in front of the intercooler and you can have it rigged up to a switch inside the car or to your throttle for it to come on at WOT. On the STi its worth 25hp in short bursts. More on modiofied cars.

Griffin said that I should expect my IAT's to be lower by 20% because of the intercooler.

I looked at spraying C02 as well, but that would be an experiment for next year.

Every 8-10F drop at the motor is equal to a point of octane. (90 vs 89).

 

I have been talking to Griffin about designing an intercooler for my car and it seems like they are waiting to get dyno sheets from Pro Stock JOhn before they start producing more.

 

They might be waiting a few more weeks since I am still waiting for FAST to work on my ECU.

 

What kind of problems are you having? Tuning?

 

FAST w/b was reading 3 full points more rich than dyno.
