buying an Intercooler

Once we get some more solid info, this post should definitely go in the Good Stuff forum. Sorry anuindlight for the post getting jacked. ;)

Alright, I got a n00b question to ask. I plan on running a 14b/16g sized turbo sometime in the near future, and I have a chance to pick up an Evo8 FMIC. Would you guys reccomend this Front mount for that turbo size? I'm not shooting for 11s or anything, at least yet. Sorry if this totally screws this thread.

This thread was screwed long ago haha. Mods should cut it up and make a new topic out of all the theory talk.

At a certain point in a balls out application I think it is easier to pick up 2, 3, or 5 hp compared to the difficulty of dropping even a couple pounds. For something the size of an intake manifold especially, I would want aluminum.


Another thing I have to add is that aluminum is much better than SS at transfering heat, thats what all this discussion is about. But consider that it works both ways. Heat may be transferring out of your intake charge. When I touch my IC pipes after a run, they are often hotter than the ambient engine bay air. I assume the engine bay air is probably cooler yet when moving at 100+mph. Of course, the better your IC is the less you have to take this into consideration.

I can see it both ways, but after thinking about this, I'd bet the difference in charge temp between SS and AL piping would be a small fraction of a degree, due to the relatively small amount of inner surface area of the piping.I recently bought a bunch of various temp sensors to put in a number of different locations including IC inlet/outlet, turbo outlet/inlet, TB and to measure ambient temps in various locations.These are going on my new car/engine/setup, and I have a generic logger that will log all info and graph the results.I suspect in most setups, the intake charge will on average be hotter than ambient around the piping anyway.I also suspect the thermal insulation qualities(or lack of thermal insulation qualities) of piping material will effect flow, via different inner/outer viscosities of the layers of the intake charge, more than it will effect mean charge temp.

This theads theory talk is pointless now. Testing is obviously the only real answer to solving the mystery and it sounds like I won't be the only one doing it. The numbers will tell the tail.
