Is it possible to boost without intercooler?
 

I've read this on one of the threads and I just wanted to know if this is really possible and at what safe PSI?

Ummmm.... Safe? The answer to that will vary, but most people will probably say about 5psi is safe without an intercooler. I wouldn't run anything without a intercooler. Are you thinking about turboing an N/A? If so, many people might think that 5 psi is pushing it.

So it is possible then. I'm just curious about it that's why I asked. I won't take the risk of not running an intercooler if I will ever add turbo to my NA ;) how hot does the air gets between the turbo and TB?

depends on the boost level, but pretty hot. I think the intercooler brings the air from the mid 200's to the mid 100's, and that's the stock top mount!
It's even more important on an N/A, that higher compression ratio makes detonation prevention very important.

If you inject inject either fuel or preferably water into the compressor or scroll then you can run all you want without intercooling.

Works very well if done properly

Til you run out of water.

yes it is possible.. i have a friend with a 86 shelbycharger running 14.8 at 13 psi wit no intercooler..it wouldnt be healthy tho

13 psi :crzyeye: did he bust the engine yet?

thas alot of boost.........ouch and no ic

Don't be lazy. If you going to all the effort to add a turbo, don't just do half a job. You'll regret it when either (a) you realise you've reached the project's low power potential, or (b) you don't realise and blow it up...
