is it true that if you run a TURBOCHARGER at VERY low psi you dont need a intercooler or injectors mod??

Question

By low psi i mean 5 or 6 im asking this because i dont wanna modify my truck extensively AND expensively! plus i have ram air ducts on the hood to get a good amount of fresh air once going. So really i wanna know if this is true.

Thanks!

Answer 1

this is is correct but you will still need the computer reprogramed to suit the turbo application.All the intercooler does is makes the air that pass through turbo cooler,hence more power...The injectors can and pump can only handle so much before it wont work...so you will have to get the trubo set up to match your pump and injecters.then get the puter reprogramed to deliver the right ammounts..Its all relatively ez if you do your research.

Answer 2

Ram air ducts are not going to help with a turbocharger; it recycles exhaust gas back into the engine. I mean they will lower temps somewhat in the bay but may not affect the intake charge temperatures if your intake itself pulls air from underneath the car or near the wheel well.

In theory you can run a turbo at low psi and not add an intercooler but it would wear quicker and might damage the engine. Cars like audis and volvos run low psi small turbos and even then they have intercoolers so...do the math and decide. Worst case scenario is that it costs you 350 for an air to air with ducting and you install it yourself.

Answer 3

If you run a turbo that low why do you have a turbo,you could get the same effect from a cold air kit.I think someone misled you on the purpose of an inter cooler for a turbo,it's purpose is to cool the air going into the manifold cold air is easier to compress than hot air because it has smaller and tighter molecules.If you have just put a turbo onto an engine that did not have a turbo on it when it was new,you are going to have running problems anyway,engines that came from the factory with a turbo have a lower compression ratio than normally aspirated engines so you might want to rethink the turbo thing.

Answer 4

The heat transfers at the turbo it's self before it goes into the engine.
The intercooler cools the air AFTER it goes through turbo, but before it goes into the engine.
