I used to always see around 20-25*F delta in boost with the small one, now 7-10*F. Either case, it's still not bad at 12psi.

has anyone done a wrx style set up with the intercooler under the hood, with a hood scoop??? that way there is no block to the radiator?? i been thinking about it but not sure if a scoop would look good on a miata hood. ANY ideas??

Im sure it wouldnt turn out as nice as his since my welding skills arent up to par, but it would probably work nicely. Any reason more people dont do the side by side thing? He said he didnt notice any reduction in cooling, though I dont know if he tracks it or anything. Even though its a smaller rad, its not blocked at all by the IC. This way would make for very clean and short piping also.
Because as nice as Spestis' car is, a big radiator is still required for track cars. Big fans will let you get away with a blocked airflow radiator; nothing lets you get away with a tiny radiator and reduced cooling system volume.

I have thought about it, and proposed it when I was first planning my turbo kit but everyone advised against. Most popular reason, heatsoak due to engine heat.

Is that 2" or 2.5" piping. Lets see the relief cuts in the hood.

That is the one I used, but the 4" thick version with the 3" inlets. It is definitely more of a pain to fit and get good airflow with the extra 1" thickness, but has more mass and less pressure drop (hard to say how much). I was seeing IATs similar to what Brain saw.

Since the pictures I lowered it slightly in the nose, and added an internal baffle. Both seemed to result in some IAT improvements, but it is hard to say for sure since I made other changes at the same time (fan shroud, more efficient turbo) and have had limited test time with the new setup.

I plan to eventually add some nose ducting to force more flow through the IC. I have also added WI for when I run the boost at higher levels.

If I did it all over again, I might consider this one. It was not available at the time when I did mine IIRC. It would be about as wide as what I have now by the time you add the 90 deg bends for the first one. This one would not need the bends since it has top exits.

If you are doing an over-the-top, I would try this one as I think it will work as well if not better than mine. Hell, in a couple of months, if I get bored, I might sell off all my stuff (IC, unneeded couplers) and try this one out. Of course with the WI, I may not need to.
