lol . Its going to depend on what you're tuning with and more importantly who is doing the tuning . I run 10 psi on a stock motor with 167k . And there are plenty of people doing more without issue because they use reputable tuners.

If your tuning sucks, blow up on 4psi. If its tuned well enough, run 15psi indefinatley.

And parts don't fail at a certian psi, they fail at a certian hp. 300whp used to be the commonly accepted "limit" for stock b series bottom ends ... but its steadily rising as tuning/tuners get better.

Search up the "highest horse power on stock block" thread in the FI forum.

 

I HEARD that you can run up to 14 pounds safetly. That was in a honda-performance book. dont think i would though

 

that is crap once i accidently boosted 15psi on my motor and bent a rod it was stock , 10psi for stock is ok but lower it if no tune

 

if you tune ive seen 25 psi and 400 hp on a stock engine...DO YOUR RESEARCH SON&gt;&gt;&gt;&gt; YOU NEWB

 

you also have to factor in the size of the turbo not only the PSI.

 

dude you dont no crap you cannot boost 25psi on stock block you will fry your rings and bend your rods i bent my rod into a C shape only boosting 15psi and on accident and my motor had great compression and run like a champ my friend blew his motor and was built with 300hp on 15psi YOU do ur reseach, ive lived and experiened this stuff dont go buy what you hear or what people say experience this **** on your own then you can talk just like me cuz ive seen this stuff happen and i want to see you boosting 25psi on stock block maybe it will last a couple days then what??? bOOM!!! turbo size matters too but your stock block wont handle 25 or 15 on stock , well my friend in his ls turbo teg boosted 15psi on stock block and it went for almost a month then blew it up

 

point is for this thread is for it to last not see how much hp you get then boom needs to last so you cant boost too high

so you have a few friends whos had bad experiences id say. youre telling me psi matters but you havent explained to me the physics of why. think about it like this. a larger air compressor usually works much better than a smaller one with the same conditions. this could be comparable to a turbo system which also uses psi as a unit of measurement.

and who tuned your friends car at 300hp built? thats a pretty sad number noting that stock blocks have made that for years without problems.

yea you can

ive seen 575whp on a stock b16 block at least at 25psi. sure it might not have lasted years. but it hit the dyno and the track making those numbers.

 

all im saying is 25psi on stock block is a NO NO.

 

no **** you can make those numbers on stock block but the point is for it to last not blow up next week or day, im telling you that on the 25psi it wont last thats what this thread is about man

in general, yes 25psi on any turbo is practically overdoing it on a stock block.

a smaller turbo at 25psi probably wont even withstand it very long AND a larger turbo will make too much power for the block to handle.

psi is only relevant to what turbo that is being run. the reason people are flamed for this is because they ask what amount of boost levels can be run when in reality, it would be dependent on the setup they have.
