Eliminating Intercooler
What would happen without an intercooler at all? How warm is the air after the turbo?

Detonation. Lots of it.

Good turbo response, though.

Why would we get detonation? Can it be tuned to eliminate?

Yes, stay below 2,000 rpm and you will be fine :rolleyes:

You aren't going to tune for 300 degrees.

Remove the intercooler and run alcohol and you'll be fine. Only alky, that is.

But if you ever put the intercooler back in, make sure you wash it with lots of soap.

Perhaps, if you were tuned for e85 and never ever went into boost.

why would you want to

Weight savings.

Everyone knows if you make a car lighter you make it faster.

Its not that I would want to eliminate the intercooler. Its just that I'm curious as to what would happen. Or if anyone has ever tried. And also as to what the air temp is right after the turbo. With the volume of air moving through the turbo I couldnt imagine the cold side being that much warmer than ambient. If you have never tried how can you be sure it wouldnt work I know of a lot of tractors that don't use an intercooler although they are diesels.

diesels are very different, they dont have spark plugs they work by compression.

it might seem like our intercoolers are small, but it does work

They used to run intercooler-less gas cars in the 80s. They would heat soak like crazy, and you'd have to tune them extremely conservatively to avoid detonation. Like to the point where you wonder why you have a turbo.
You "could" do it, but it would be completely pointless and you'd need to do extremely careful tuning so as not to blow it up. I'm not sure that the 2.5 is built durably enough, old turbo motors were tanks (or they blew up).

intercoolers are for pussies. I run a straight pipe from the turbo to the intake manifold. I only do this when I'm washing the car because I don't want to get any soap in the IC, nor do I want it getting into the turbo or manifold so I block them with a pipe.
