Can a stock ls1 intake handle up around 15lbs?? i have heard rumors of stock intakes craking...just wondering if this is true or not... I was thinking about going with the weiand intake if the stock one will not handle the boost...is this a good idea or not??

 

Never heard of it. My car has seen 13 pounds with no problems. I definitely know many here had gone well beyond 15 pounds unharmed...

SC-

 

Mike Brown and Steve Turley are running 25-30 lbs of boost on a LS6 intake and haven't had any problems.

 

a couple of people around here said that heard of the plastic cracking under high boost... i wanted to see if this is true or not... if it is i am going to go to aluminum... but i don't want to spend the money if i don't need to...

 

so then use the stock one and if it cracks, which I seriously doubt it will, THEN go buy an aluminum one. why fix something that isn't broken???

 

you wont crack it. its fine.

mine has survived spurts over 30psi and continuous 17+psi use over the last two years

 

yeah these won't crack...don't go pay money for the alum. intake...

 

I would think that you would blow the gasket before you cracked the intake.

 

15psi on my stock ls6....

no problems

 

Yep, my stocker saw 18ish when i still ran it. No worries

 

My LS6 intake has seen 18-21 psi.

 

Yep, We have been to 30.5psi with no issues, except for the tires.
