that's brainy's old IC - so you know it fits

 

yeah i do, thats why i thought i might want to get one because i see it fits pretty good. Did it work pretty well?

which one? The small one?

 

he's had that small one and the big version- all in his pic links above

 

Yeah, thats why i am asking him if he saw any AIT changes with the big one.

 

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.

 

wow, thats almost half the temps.

 

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??

 

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.

 

I made did mine a few weeks ago. Here how it looks.

 

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

 

its 2". I will take a pic of the cuts later. they are not too bad actually and were really easy to make with a dremmel.

 

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.

 

Rushin WTF are those in your grill?

 

those are badass hella supertones.

Seriously,

 

yes, stock horn crapped out and i had a set from my wrx left. They scare the **** out of people that are in my way.
