Can an intercooler off a Volvo 760 Turbo flow enough air to work with my setup? The size of the IC is very close to the 928s radiator; however the core is only 1 ¼ ” think. Since I don’t have my AC anymore and the condenser is already removed I was contemplating to put this IC where the condenser used to be.

The overall IC dimensions are: Width (29” at the top, 23” at the bottom) X Height 18” (this might be a problem) X Thickness is 2 ¼ “, In/Outlet is 2.5”.

The core dimensions are: Width 18” X Height 17” X Thickness 1 ¼ ”.

Any help is greatly appreciated!

Is that the 2.4 liter 180 Hp Volvo ? if so then I think you need to run two of them

Funny you should bring up that Volvo IC. I was talking to Jim Page about an air-air setup to run on my track car, he mentioned a few Volvo units he suggested I try. Quality of these units is excellent, and they are very easy to find in junkyards (see cheap).

Yes, it’s the 2.4L one. There are no other Turbo Volvos available here in North America. My rational was that they run at around 10psi stock in the Volvo and since I’m only running a max. of 6psi it might work. The only reason I’m contemplating this cause the local wrecking yard has one for $65cdn!

They are bit on the think side but the over dimension of the IC is pretty big.

Is you track car a 951 or a boosted 928? Did Jim Page mention anything to you on the capacity of the Volvo unit? I just want to know if they are good enough for my application.

1979 928 - no boost (yet). I made a comment about boosting it and going air-air. He brought up the Volvo unit since he knew the overall size might work well in front of a 928 radiator. He doesn't have any data on the capacity. The idea did not go any further than him mentioning it. I'd give it a shot, what the hell, it's only $65 (plus the plumbing, instal......)

As a rule the capacity of an intercooler on production cars tends to be on the low side to limit the lag associated with pressurizing the entire volume of the intercooler and associated plumbing. So If Volvo designed the intercooler to the 2.4 liter displacement and about 180 HP it is probably too small for a 5 liter engine at well over 300 HP. But for that kind of money it might be worth a try !

Hmmm I think Jim, you are right. This IC might not have the required capacity to feed a boosted 928. I wish there were some better (thicker) OEM choices available. Almost all the turbo cars are 4 cylinder except for a few and all the 6s have ICs in the fender not in the front. A diesel 6 cylinder car with a front IC would be the best candidate. Unfortunately, 6cylinder diesel engined cars are very limited on this side of the ocean.

If anyone has any recommendation for an OEM IC that could work, please chime in!

Imo, the idea is a good one. I think issue is engine temp also ... adding this huge obstruction to the rad may cause the heat to affect engine temp. Flow would also be less than one ould want through the two (in the case of an ac car, 3) ... IMHO.

heinrich

try, see what happens.

If I'm not mistaking the car this IC comes from,the swedes use the stock IC in tuned applications well over 300 hp... Bigger IC's don't make lag. Restrictive IC's make lag. The increased volume is filled so much faster by not having a restriction between the IC and turbo (read: small IC/pipes) that your lag is probably less with bigger pipes... that is,unless you go overly big (4.5" pipes) of course...

In my case with the condenser already out, one Volvo IC would not cause any over heating problems. Two might.

I could perhaps use two Volvo cores welded together and build some end tanks to fit the 928, but by that time the cost will be the same as buying a generic IC from ebay. The Isuzu truck, NPR, ICs (small version) would also be a good candidate, but they are very hard to find at a reasonable price.

Imo000

Hmmm, now there is something to think about. If a Volvo with 300hp can still utilize a stock IC, then this just might be large enough for me. A 300hp Volvo needs a lot of air and if the stock IC is large enough to flow that much (high pressure lower volume), then my low pressure (larger volume) system might be a good combination. Now that I think of it, is it possible that a 300hp Turbo Volvo would flow that same volume of air as my boosted 928? If the volume numbers are close, the Volvo IC could very well work.

hacker-pschorr

You beat me to it. These motors (volvo's) are good for well over 14psi with stock parts.

Imo000

What the heck, sounds like this could work. Since its only $65 cdn, I’ll buy it.

Now let’s see if it can be shoehorned into the 928.

Unfortunately I will not be able to test drive it till spring.
