Hi Tony,

I think that was one of DeltaP designs ?? I know they made some nice looking pulleys and brackets for Centrifugals too. BTW, what ever happened to them?

Unsure, but nice IC. Not blocking the radiator appears to be a huge consideration...not so on most japanese cars, but on the 928, yep.

My air/air experience was soley to produce a easy/inexpensive/easy to install way to cool the air, though not without it's criticisms. Rarely is the easiest/least expensive way the best way. I now know it works well, all without over heating, but you still have to cut holes.

Has anyone ever dyno tested the air/water setups back/back (same boost) & with temperature testing?? I was trying to do this on the dyno 3 weeks ago when I realized that this whole time I was running on a mere 3psi, but hey! 12.9 @ 110mph on 3psi!

Mark,

No IR testing while on the dyno, but 4 pulls with only a 5 minute break in between pulls left the intercooler VERY cool to touch. 8 psi, 1 aborted third gear pull (due to excessive wheelspin), and 3 in fourth. This was on a Dastech dyno.

The same car, after driving several hours in 85 to 90 degree heat is again cool to the touch. Within 5 minutes of shutdown though, the intercooler picks up the heat from the engine. No issues with Air-water after a year of street use.

The DeltaP setup is a good ides, but so much of the standard radiator is blocked. Show me one factory IC setup where the IC ducting blocks any significant part of the radiator. I doubt you'll find one. If you going to use an air-air IC in front of the radiator, your better off not blocking any portion of the radiator.

This setup covers the entire surface area of the radiator top to bottom. Not to mention the custom duct work guarantees every air molecule that enters the front of the motor has no where to go but through the IC / Radiator. Most aftermarket setups have the IC dangling out in front of the radiator. Sure some air will go through, but not much compared to how much air is going around the IC.
Air will always take the path of least resistance. Hitting an IC at 100mph is like hitting a wall, unless you give the air nowhere else to go, it will go around the IC.

or eliminating the headlight TQ tube and all the sheet metal he had to cut to do that.
While the set up is great, i think that is over the limit for the home DIY install thing.

Some SAABs and Volvos block a fair amount of the radiator. I think SAAB Sport Sedan intercoolers block nearly the whole radiator.

Matt,

You have to read Hackers post a couple o times before you fully understand his statement. He is not saying that having the intercooler "core" (the finned part) in front of the radiator is the issue, he is talking about the "solid" ducting and end caps blocking flow into the radiator as shown in that photo I posted. If you look at the photo he posted the "finned" area of the A/A IC is exactly the width of the "finned" area of the radiator behind it. Therefore no air flow blockage to any part of the radiator. If you look at any Turbo Diesel truck like a Dodge Ton Pickup you will see that the intercooler is as big or bigger than the radiator, but the endcaps and solid ducting are not obstructing air flow to the radiator "fins" behind it.

FlyingDog

Ahh... gotcha. Now I see "ducting".

What, are my posts not fully understandable? j/k
Bingo - I was going to comment on the Volvo / SAAB part until I read your response. Most Volvo Turbo setups I have seen the IC covers the entire radiator area. I am actually looking into using an OEM Volvo IC for my 928 track car. Might not be the proper size, but if it's anywhere in the neighborhood, it's a very well made OEM unit that can be used, and easily found in most junkyards. Why re-invent the wheel?

Most of what Jim and Todd do are well beyond any DIY install. They do not develop what they do for the interest of making a marketable product. They are pushing the limits of 928 design for the sake of making the most power possible out of a 928.

FlyingDog

I was told by a turbo Eclipse owner that they like the SAAB 9000 intercoolers. He said they're cheap, huge and efficient.

If you can ever use an OEM part vs aftermarket I will guarntee you it's better quality.

Imo000

Durability is always built into every original factory part. That's the beauty of using OEM parts. They WILL last.

TAREK

Not necessarily a rule. In many cases, the manufacturer is the same, and quality is not compromised. And in many other cases, the aftermarket part is superior in quality and durability, because it happened to be less restricted on cost, given the application.

Point is, it's a conscious decision manufacturers make, based on restrictions and demand.

Tony

...and that number is.
