Like on the series 4 and 5. I have an idea to do a topmount IC setup and was wondering if it had been done. I've searched with no luck

 

That would defeat the purpose of a long runner intake manifold (torque)

 

gracer7-rx7: What do you mean?

spekdah: I have a horizontal mount. Not quite the same...

 

Long intake runners allow for a nice torque curve...

 

I don't see how that relates to a Top Mount Intercooler (from the OP). I'm missing something...

 

1) won't fit.

2) heat soak.

 

Heat soak +1

Hot engine, heat rises. Also you wouldnt get much flow to it without a hood scoop like the Imprezas, but theres a reason that STi owners upgrade to front mount IC...

 

Unless you're talking about an air to water setup, I would stop this train of thought right here.

 

It would be the most stupid thing you could do, unless you where doing this to make a place to cook bacon while you are driving, if your doing for that reason then its awesome. Make sure you make a tray under the intercooler to catch the bacon grease, no one wants to clean that off the engine

 

mmmmmm bacon....

 

Its the king of meats, forget steak, unless the steak is wrapped in bacon, a top mount IC would be awesome for RX-7 meets, you could use it a a grill to make the bacon wrapped hamburgers and hot dogs.

 

I <3 thread jacks...

 

well, thats all great but you still haven't answered my question. Has it been done?

 

yeah , to go with their hair products

 

Actually, SR motorsports had one BITD.

I don't think it sold well, as it's not a good config with everything else that's under there... they're typically used w/ a hood vent/scoop.

 

This is the SR one, but it doesn't sit on top of the engine...

 

There is a reason why every car that comes stock with a top mount replaces and relocates them. Even with a hood scoop, the air does not have a good path to follow as the back side of the intercooler leads right to the top of the block, ie BLOCKED!

 

That SR one might work well with a scoote hood. too bad scoote hoods are not aesthetically pleasing to me...

 

It would work the best with a reverse scoop that sucks the air out.

You need a custom duct as well.

 

I have sth similar to the SR mentioned above by johnchabin.

The car will hopefully be tuned next month; and then I can inform you about the numbers I had, in case they help you decide what to do.

Intake/Outtake modifications for the air in the engine bay are definitely needed.
