I understand what you're saying sir, you're right. but to be able to test out inter-cooling in general will have its benefits. Yes it will heat soak shortly after I've started down the road. But the basic theory/set-up will get a test and in the process I can save up for a proper cooler that will cost more that 10x as much.

 

with it getting a little chilly, itll be better then running it mid-summer


but ya, the mid mount sounds better lol.

 

like stated above, your going to run into heat soak..

spend the extra bread now and not have to redesign the i/c system down the road bc you wanted to use a smic core some one gave you

 

This link gets passed around a lot in the 300zx community regarding side mount intercoolers.

not sure how well it applies, but it does have some nifty info about them.

As far as I know, the only real difference (other than mounting location) between a front mount and a side mount is the physical size. Typically, side mounts are thicker. The disadvantage is that cooling has a direct relation to surface area. Front mounts cool better as they have more surface area exposed directly to the air. But we have also seen how a smaller, but thicker radiator cools an engine just as well (if not better) than a bigger, thinner radiator.
I think that because you're sticking the side mount up in front, you don't have the radiator in the way, it can get plenty of fresh air, The only issue is going to be channeling the air through it. With some air guides in place to force the air to pass through it and not just around it, and a fan to help suck even more air through it, I don't see heat soak being that big of an issue. At least not at the lower levels of boost you'll be working with.
