How much boost can stock Intake Manifold handle?

Hi, I have done my research and concluded this:

1)For N/A the KMS intake mani is crap (you loose power)
2)For FI, it MIGHT give some gains ....

What I want to know is that if anyone is running a KMS intake with a turbo setup and if it provided any gains?

With a complete Turbo and Alcohol Injection setup, how much boost can the stock manifold handle?

Whats the max boost (with Alcy) that anyone has run with the stock manifold without any problems?

And is there any chance of the manifold 'blowing up' with turbo? (like someone's did with a 75 shot nitrous)

Thanks!

stop worring about the manifold...
the engine will blow 4 TIMES OVER ... before the manifold does.

and the manifold BLEW UP with NOS cause.. well HELLO... ITS NOS. its a highly explosive gas, hence why we use it, it probally predetonated in the manifold and BOOM.


there is no type of EXPLOSIONS going on in our cars (Turbo'd) that arent Factory Made.

what he means is how much positive pressure will our manifolds actually take. I doubt anyone knows but I've heard people running 12-15 on stock but dont hold me to it.

he is right, the IM blew b/c of "puddling". This is when fuel builds up in the IM.

n2o will only combust when mixed with fuel.
