Don't a lot of people raise the rev limit to 7500? How safe is that?

Kind of off topic (like it matters?

) but is it worth it to raise the rev limit on the Z and to how much? Will probably need an UpRev tune after I get HFCs early next year so I'm trying to figure out everything I want to get done with the UpRev.

Mine is currently set to 7800 with my UpRev. I know some people set it to 8000.

Do you think its made a significant or worthwhile difference? I only want to do it if it makes a difference and is relatively safe. If I do have it raised, I won't even go that high very often. Just when I'm at the drag strip or doing some spirited driving.

Tuning your car is never relatively safe.

Well since the Z is making all its power up high I dont mind being able to rev it a bit more. I kinda wish I went to 8k so I had more but I hit my limiter kinda often so I suppose its a bit safer, for me, to have it at 7800. I dont personally see a prob w it set that high and I have yet to hear anyone mention it being a problem either. All in all I dont think it makes much difference but its nice to be able to take it there if you want to, just personal preference I suppose. You wont regret gettin the UpRev though, its AWESOME.

I would raise your limiter based on where your car makes power. I make peak power at 7800rpm and it holds flat till 8100 so thats where I set it, I also have 4.08's so the extra rpm's can be useful.

Thanks guys! Looks like I'll have to wait till my car is on the dyno getting tuned to figure out what to do with the limiter.

I think you will wanna be at 8k. Like I said I wish I went that high. The car is making all its power way up there so it only makes sense. Getting it dyno'd was so much fun, I had a kid getting his 2012 STI tuned drooling over my exhaust note

Get the rest of your bolt ons on Blades and get that biatch tuned, you will love it.

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.
