Not sure how safe 7,500 is. I wouldn't feel comfortable spending a lot of time up there. My limiter was bumped up to 7,300.

Yeah. I'm not looking to rag the car out....I do notice it pulls timing at around 6800 rpms, short of red line....

Just curious what is "safe"...seen guys at 7750 on regular 5.0s that seem to work....then again, I revved a stroked f20 to 11k hundreds of times with no issues, other guys blow em up with one rev to 9500....

I guess the 7300 limit you run sounds like a good compromise. Plus if your engine blows up, I can lower mind.

^^^ This (and the stock rev limiter kicks in around 6850).

Intake + tune and she pulls like a motherf*cker to [insert new redline here].

Yeah, it did. With the Steeda intake (and any other brand intake) that flows significantly more air than stock you really gain a lot of power up top. The car pulls hard to redline.

Yeah, I have seen people running 7500+ but they are more serious racers and don't really care if they blow it up.

I think 7300 is a good compromise.
