Now that I've got the final location of my turbo(I'll see if I can get pics up this weekend) I've been thinking more and more about the intercooler idea. I really like the idea of having both the inlet and outlet at the top. It would seem to constitute less of a piping nightmare. This would be going in the a/c condenser space under the radiator shroud.

Is there a disadvantage to running a two core intercooler one right next to eachother with the airflow running down and 90 and run back up? This solves the problem of having the end tanks hit the hood ribs on a normal left to right flow intercooler with two port on the top.
I figure you can get twice the cooling distance this way making the intercooler more efficient and you can keep the air velocity up more than just making one large intercooler that would slow the air down to expand all the way across the radiator area. Lets hear some ideas.

Brian,
It all depends on the size of the cores.. putting them in series if too small will cause a big flow restriction and the mength will cool well, but the cost might not be worth it! but the inlet outlet on top of the shroud would be highly beneficial!

I got the measurements of everything yesterday. The thing is going to be about 27.5" wide by 14" tall. You loose 2-3 inches of height. by having the thing tilted, but there is no other way to make it fit.

I'm pretty sure that I can get a 2.5" pipe between the radiator and the hood, but it's going to be REALLY tight with some grinding needed. hopefully I won't need a custom oval tube on the output side. I think it might help with not having to speed the air up again, but it would be alot more expensive.

 

I just talked to a turbonetics intercooler guy and he told me that when the air has to do a 180* turn with an end tank like the picture above it causes a 4-5 psi drop.

He suggested making it flow side to side and making shorter so that the intake piping can snake around the ribs of the hood.

One of the big problems is 3.5" core is going to be really tight in where the IC goes if you make it as wide as it could be. Putting it right against the radiator doesn't seem like a good idea.

Not sure what I'm going to do but the price quote came in at $1165. I think I'll have to do some figureing.

 

Chris,

Is this the intercooler that you were looking for???

 

Brian,

Yes.. it will be very similar.. with the exception that the bottom tank will only have one inlet. amnd it will probably be a little b******! where did ya get that or is that now your intercooler? lemme know!

and tell me some more about your turbo location.. share man share!

Chris, I found this at http://mall.toohighpsi.com Remember the '93 ruby red with the twin stroker and mufflers under the front of the car. That's what this IC went for. I've been trying to get ahold of these people but with no luck.

The more I look at intercoolers the more I've found out that I can't have my 1000hp IC. I think I'm going to be stuck down to a 1000cfm IC. But it will fit and make the plumbing come in and out of the top. I think I'm gonna go with Griffen core. They retail for the entire assembly for around $520 for a 1000cfm IC that will support 700hp. If I really want more I'll just turn up the boost. The psi drop increases but at that point so does my turbo efficiency so the extra boost may not hurt.

So for half the price of Spearco I think I'll be happy. I'm not sure what the wait is on Griffen, but Spearco was a 8week wait.

Now I just have to figure out where to mount my ATF coolers...

As far as the final turbo location it is mounted in the same direction that BTF has his. Mine is just back a little bit and more over to the pass side. I'm trying to talk my housemate into letting me borrow his digital camera, but I'm leaving town for a week to do the thanksgiving family thing so it may be a bit.

 

You can definately make the 1000hp intercooler fit.. All you need is a tig welder and a little immagination!!! I have the Turbonetics (spearco) 1000hp core and it fits nicely in front of the radiator. The trick is to take out the stock radiator shroud and stand the radiator straight up and down. Seriously, the best advice I can give you guys is to buy yourself a good Tig welder (I bought mine used for $1,600) and learn to use it. Having that Tig has opened up many many possibilities during my buildup. If you have to pay someone to do all of your fab work (sometimes more than once) you'll go broke in a hurry. My Tig has paid for itself many many times in the year since I've had it.

 

Tony, are you talking about the 3.5"Dx20.8"Wx10.5"H core? I can see how to make it work, however, not with keeping both the in and out on the top of the shroud. Where do you have your pipes running in and out of?

With the core that you're using is there enough room to get a pipe along side of it to an end tank on the bottom? If so that might actually work. The only thing I would be worried about is the large end tank on the bottom blocking airflow to the radiator. And the end tank on the upper side. There'd be only 10.5" for air to get through to the radiator.

As far as welders go, I've got a good flux welder that gets me by with just about everything I need. I definately couldn't do this project without one.

 

My blower outlet goes to the intercooler via under the radiator. I made a wide flat (relatively speaking) inlet to the bottom of the intercooler. You can see this from looking at my pictures on the Procharged BB thread. All I can say about the end tanks is we'll just have to see what happens this summer... I am thinking about making some air directors to keep the air in the rad instead of taking the easiest route around it... We'll see... I'm not sure which turbonetics core I bought... But if you go to there site it lists for $800-900 and flows top to bottom...

 

I thought about going under the car, until I looked at my skid frame rails. They are all scratched up from bottoming out I didn't want to take the chance of doing that and damaging the intercooler or even worse sending metal shards into the engine.

I'm gonna be going for 15psi tops on my 393ci so I shouldn't need too much more than 1200cfm. 800hp seems like an adequat goal for now, maybe. Its better than the 0hp that I'm making now.

 

If if you bottom out and dent it (which could absolutely happen), the aluminum would most likely dent or tear.. but not shatter.. Even if it does shatter I doubt any pieces could find their way through the intercooler to your motor...theoretically of course. And I definately hear you on the Zero H.P. thing. I am finally getting everything put back together with my new rad. shroud, cog set up, replumbed intake, and monster Spal fan... I think I'm ready this time. Just wait until you see the intake to the supercharger......!
