what would be a safe boost on a stock engine........and how much extra hp would 6-8 pounds give me

 

6-8 psi on d-series which it what im guessing you have

 

what motor ?? any fuel upgrades ??

Really depends on ur stock compression, how healthy ur motor is , what motor it is and what ur running for extra fuel

 

go to the forced induction forum

 

depends on the tune. breaking points usually come with power... most d-series rods wont last past 220whp, while b series engines can take quite a bit more stock.

 

It's pretty apparent that you're new to the world of Forced Induction...i'm not going to give you any grief because we all start somewhere. For you, that somewhere is the Forced Induction FAQ. It's at the top of the FI Forum. It will give you a lot of good information and answer many of the questions you currently have.

As for the question at hand...You need to understand that boost pressure (PSI) is a totally irrelevant measure. Asking your original question is the typical "newbie red flag." Just to reiterrate, boost pressure doesn't mean anything. The power created by a certain turbo is what breaks parts. The only time you need to concern yourself with boost pressure is when you buy a MAP sensor or when you're figuring out a turbo's efficiency range.

It's a fairly simple concept really...a larger turbo makes more power at a certain pressure than a small one due to the difference in air flow. The measurement that people generally use is lb/min flow rate. That's the only reliable comparison factor for most turbos. I would continue to babble away, but if you read the FAQ, you should have a pretty good understanding of what i'm saying.

Safe Stock Power Ranges
D series - 220-240whp
B series - 300-325whp

People have pushed them harder, but for the most part, that is the "safe" range. There are a few confounding factors that may change those numbers, but use that as a guide
