how much boost can the stock internals handle?

 

I will go ahead and say 25lbs. But why would you ever run that? Its probably more than 25 but you'll have no reliability on the engine.

You'll never run that much on the stock blower and you won't need that much with a bigger blower. Also, if you're thinking turbo, then only with a small turbo would you see that much boost. Go big turbo and you won't need that much boost

 

Boost?????? Do you mean hp? Boost is not a measure of power

 

i meant boost, like the pressure put on the engine. And im not planning on going anywhere near 25lbs. I just had an argument with my friend who said that anything higher that 15lbs would blow my engine, and i told him he was wrong.

 

boost doesn't mean anything. power is what breaks parts.

 

It all depends if your setup is tuned correctly.

 

what are up you ss/sc or ss/tc? Its not all about how much boost, its also heat and the amount of pressure you are running into the head.... all about pressure, not boost.

 

4006 psi

 

i know about the heat, when i start my build i have plenty of cooling mods drawn in. Maybe a dumb question but is boost not the added psi that is going into your eninge.

 

0n an m62!

its 9006 for a 3071r lol

 

Nope. The PSI you see is intake manifold pressure. Boost doesn't equal HP. In fact, the more you are able to lower your boost, the less restriction you have in your exhaust, etc. I started off at nearly 20lbs with the 2.8 pulley and 7k rpm. Once I opened up my exhaust a tad, I was able to drop it down to 17lbs... which is a good thing and equals more power.

 

ok thanks man, im new to alot of this.

 

negatory on the 9006 psi.... i have metal shavings in the oil pan, do not believe there is much life left in the engine

 

tell your friend to end himself. boost is irrelevant. its about cylinder pressure

 

x2

 

So, when my car was getting 14psi out of a 2.8" pulley, that was less power than the guys getting 18psi out of the same pulley, right?

 

of course! moar boost fgt!

 

Damn, I knew the car wasn't as fast as it should of been. I could only just barely beat a C6.
