Most Boost Stock Bottom End?
Who is running the most boost on a stock bottom end? I'm not looking to turn this into debate on what it will hold. I am just curious. Include some more info about your setup as well.
Going off My autometer boost gauge I see 18psi at close to 7k rpm. This is a t-trim v3 with stock heads,intake, hi-flow cats, and stock TI catback. I suspect I would see closer to 15psi with some good heads and a 6600rpm shift point or so.

Most wehave EVER done was 13psi, but we had upgraded the rod bolts with Katech rod bolts. Other than that, we stay no more than 11.

I ran 14lbs on my C5 with only internal being valve springs.Was like that for 3 years on straight 93octain.
My buddy's 5.3L Avalanche is running 16lbs on the stock shortblock and has for the last 30k miles.
Tuning is very important to keep it together.
