my idea for intercooler cooling, will it work?

[finboy]

well taking a journey through pick your part, i stumbled upon an 280z. upon closer inspection of the engine bay, i found that there was an electric powered air pump (best i can make of it) with ducting leading to the intake manifold. this pump sucks in cold air and blows it ONTO the intake manifold, cooling the fuel rail and runners.

most people are using water to cool their intercoolers, but that requires aother resivoir, or using up windshield washer fluid whenever you want to cool the IC.

my thought was using this pump do do the job for you, simply have it on a switch, and turn it on when you want cold air on the heatsoaked IC.

thoughts?

the burgundy 280z? i was just there today, theres a mazda 626 turbo there (IHI) turbo

That air pump idea sounds really good, keep us updated if you do go into it :thumbsup:

well that wouldnt help as much as an intercooler, buts it is a good idea. iv never heard of it either.
oh and im kinda stupid, so whats a 280z?:D

the 300zx's older brother

Well the only ones i know are the 180sx-200sx-240sx-300zx-350z:D

datsun 280z the original fairlady

[kevie88]

Yep, it went
240z
260z
260z 2+2
280z
280z 2+2
280zx and 280zx turbo
300zx and 300zx turbo 1st gen
300zx, 300zx 2+2 and 300zx twin turbo 2nd gen
350z

I used to know all the years but I've since hit my head a few times :D

the idea of this is to aid the intercooler.

while the car is sitting in the pits, or staging lines, this pump could be activated by a switch to blow cool air on the intercooler, preventing the dreaded heat soaking effect.

hmm, I think a ghetto Home-Depot sprayer would work better. Water has way more cooling ability than air. I think that's what I'mma gonna run.

[finboy]

combo of 2 maybe?

[///M3]

meh i guess it could keep it from over heating, but i rather just get a intercooler that sprays water on its self to keep cool.
and over heating is not a problem in the pits, only f1 cuz i dont think they have a rad.

Something much more lightweight, simple, and efficient would be a Nitrous Intercooler Spray. Even a windshield washer pump spray on the IC would be lighter and more efficient (and quicker to draw off heat) than a fan.

does anyone know how well these worked on the 280's?

i'm starting to think it might be worthwhile hanging on to.

I've got a intercooler fan going on my intercooler.
Finboy is you need more information I've got a lot.

"Next I installed the intercooler fan from SCCoA and saw a significant improvement. With fan running and the car parked the ambient air moving through the intercooler has a velocity of 4.5 MPH. Although this is not very high it is enough to make meaningful improvements. I noticed a reduction in all temperatures throughout the system. At a 60 MPH to 80 MPH cruise the intercooler`s exit air temperature was only 67° compared to 100° without a fan. Around town the exit air temperature with a fan rose to only 75° compared to 112° without a fan. Also observed was a reduction of supercharger air temperature from around 175° to 123° at cruise speeds. This might seem a little odd at first but is explained by the fact the SC has a supercharger bypass which under no boost conditions circulates air from the intercooler back to the supercharger`s intake. This cool air cools the supercharger and tubing.

On the average this is an improvement of about 30° that translates to about a 3% improvement in power or about 10 HP, not bad for a $90 part."

The problem with running any sort of 'water' (I would use windex) solution would be at race city. The last thing the race city tec's are going to want is somebody spraying water anywhere in pit lane or down the track. I suppose it would be ok if you part your car but things are still getting wet and likely to drip.

well, mine crapped out and stopped working on both of the 280zx's I had, so it might not be worth it to hold onto it. Does the motor still work?

[finboy]

hmm, i thought about a fan on a switch, and then shutting it off once driving comenced, but seeing the drastic temperature changes you've seen, i may look into this again, as a fan will probably work much better than this pump.

i still might consider using the pump as an intake manifold cooling system, as the head is a non-crossflow design and the turbo/exhaust manifold are direclt under the intake.

i also heard race city doesn't like water anywhere near their track, which is why i was considering an air source.

i'll check and see, 12v source and ground i take it?

Well i guess you could use co2 or nitrous:dunno:

Yes but it matters what material the core of your intercooler is made out of. With mine if cooled too fast it can cause damage to the material. Plus these kits you buy become very expensive very quickly.
