I love articles like this. It makes me think I am a little smarter now. Although actually I'm still clueless lol.
Anyway I thought I found a secret way to make my car faster. So will share it and tell me if my secret is so off balance or not. Oh any my secret is copy righted so no one can copy. Just kidding. Here goes. Don't know how to explain it but will try.
I had this thought. Air comes to the turbo via the air filter which gets air from outside the car or sometimes inside the engine bay. This air is then sent to the intercooler which sends it to the engine.
I was thinking of running a second intercooler. So basically air from outside the car or engine bay will go through the intercooler through the air filter into the turbo then into the second intercooler then into the engine.
My thinking was this will help the turbo suck colder air helping it boost better.
Am I totally off track or will this idea work.
Without discussing the fact that a second intercooler might not fit in the car. But the thought if it could. Will it work. Would the results be worth the cost.
Thanks.

That idea unfotunately won't work. The Turbo is so hot... there is pretty much no point in cooling that air down. The Turbo has got exhaust gases spinning it. Besides, its entire point is to compress air and make it more dense, the intercooler then cools the hot air down after being compressed (as we all know friction causes heat, so making air more dense heats it up anyway).
In theory it sounds like not a bad idea, but in practise its impractical and the gains would be non beneficial, if any.
They should run encase that Turbo in liquid nitrogen, then push air through it. Ha ha.
Think of how Nasa runs their rocket boosters. They need to keep the engine cool. How they do this, is have tubes running alongside the inside of the booster with their liquid cooled Fuel, which is like -1000 degrees or something, which pretty much makes the whole rocket booster safe to touch on the outside and above the blast. So they use the fuel to cool the engine before it gets ignited...
Pretty smart.
Anyway... enough rambling.

In theory its a good idea.
A few probs though:
When the compressed air leaves the turbo, it is pressurized, it is 'pushed' through the intercooler.
If an intercooler we on the intake, the turbo would have to 'suck' more in order to achieve the same results.
Therefore the efficiency of the turbo is decreased and the life of the turbo is decreased.
I have seen guys in the states run a watermeth kit with a small nozzle into the intake in order to achieve what youre thinking, it works, but its kind of overkill.
Rather have a correct size air filter that is placed where ambient air can be sucked in.

intercooler cant cool lower than ambient air temp so one after the filter will have 0 effect on air temp because the air is already at the same temp...
intercooler only works because the compressed air from the turbine is hotter than the air passing over the intercooler...

Lol. Well it was worth a thought. See lucky I asked before I went and tried it.
I will need to go back to the thinking lab.
Make sense why people put bigger intercoolers.
Now another question.
Can an intercooler be too big.
If I upgrade my intercooler. Is there a recommended size to upgrade to or is it logic to go as big as u can to get the best results.
Thanks guys. Very informational.
