How much boost??? How much boost can the stock bottom end of an LS1 handle? Im this will be a steet car with some track time, but not like every weekend.
i deciding on if i want to buy a crate motor or beef up my top-end and slap on a procharger. However, I'm buyin headers next yr and only want to buy them once, so i need to make sure i get the right ones, and the "right ones" depend on weither i decide to go with a crate or a SC.
the car currently has 83K miles on it, and some piston slap (tho not that bad).

i read that sticky "the tru cost of forced induction" and most of it pertains to turbo's... does it cost just as much (potentially) to have a SC also...to do it right that is in order to prevent my motor from going into orbit?

i just want to kno so i dont get a different impression and end up over my head. I would want to do it RIGHT. And do it RIGHT the first time. Im not one to cut corners and half *** things.
so they are both the same amount (around)? In other words the "optional" and "required" items listed in that sticky apply to turbos and sc'ers?
i just want to make sure i have a clear idea what what is involved

yea ok

8-9 is safe with good tuning; the number 7 ringland will be the first to go if there are issues.
I guarantee you I can have an LS1 make 100psi safely. It may only make 400hp, and may have a 2.5" metal plate blocking 85% of the throttle body, but it will make 100psi.
Watch. I'll borrow your LS1 for a day. I will back the engine with a full guarantee, and I'll also guarantee you will see 100 psig. It will probably be slower than before, but what does that matter?

for the OP, about 600 RWHP seems to be the edge on the stock bottom end. Some make more with great success, some make less with disaterous results.
I personally made over 600+ for quite a while.

FieroZ34, we all understand your point about psi vs cfm. However, I feel that you are doing a great injustice to some of the beginners here. Leave the fluid and thermodynamics disussions in the advanced section, and let the "simple" questions be dealt with simply. The original poster obviously has a near stock motor, in which case 8-10psi would be pushing it. We can all throw out simulated variables for almost any situation. but that is irrelevant in the main forums. Since you are intelligent enough to understand that life isn't as simple as people would like, please explain your answers better, or put them in the advanced forum where everyone should already understand.
We have no idea what his engine is. All he said was a stock bottom end. So what are we left to assume? If his entire motor was stock, he would have said so. But he only said stock short block. So I'm assuming the long block components aren't stock, like it's a head/cam/intake car, like most of the cars on this forum. Thus his VE is most likely above 90%, meaning 8-10psi is A LOT, and probably pushing over 550hp as it is.
If this stuff is to complicated for him, he needs a new hobby.

Correct me if im wrong but i was under the impression that the procharger kit is a "complete" kit meaning not much hidden costs as far as getting the supercharger system installed and operating. Now getting your drivetrain to take the abuse is a completly different story.
