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

did it make a difference?

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. ;)

thats just the stock manifold falling flat on its arse, lol

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.

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

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

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.

Nah, datalog shows pulled timing. The bama guys confirmed that's how the stock limiter works.


The z was similar, pulled earlier, but less aggressively. My z pulled timing about 7100 rpms. A lot of the peak tune gains on both cars are from going to a hard limiter

Tuning your car is never relatively safe.

War on tea

troof

Mustang this and mustang that

M3 me M3 you

Z who Z me Z you

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.

I smell two more converts :rofl2:

You know what I meant though :p

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 feel like this anti-MD meet this Saturday is gonna be a 5.0 meet with me being 5.left out :icon17:

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

Definitely. Getting G3 intakes installed on Thursday and will probably get HFC's early next year. After that I'll be ready for a tune.

On the Z, for a relatively safe tune, I the max I would go is a hard limit at 7800. Given how the car feels above 6500 I wouldn't be too comfortable at 8k on a regular basis.

I'm never that high on a regular basis though. Don't really ever go past 5k while I DD. Probably only get close to redline like once a week at the most. I think I'll be ok with having it set at 8k for when I need it, probably just at the drag strip.

unless you are Twin Turbo'd.... :tup:

Well if you aren't there on a regular basis I don't think you need to run to 8k at all, especially if you are concerned about reliability. I ran mine to 7800 and that was fine.

Meh we'll see how it goes. I might get addicted to the higher rpms and the higher power up there with the intakes. :p

I'll go there when I want to have fun, which is pretty much just on the weekends.

/\ any word on if the overall dimensions of the stang are going to shrink a bit?

DD, the GTR is NOT more fun than the Z, it's just a big auto car that feels like it's being caged and pent up and you can't even enjoy 1/10th of it's potential on the street (legally of course). the Z is great fun to zip around town in, it's way down on power compared to the GTR, but you can use what power it has on the roads vs. not being able to even really begin to tap into your car's potential.

Our Z is uprev'ed to 7900 rpm. It made power all the way up to that point on the dyno as well. I feel it's safe but at the same time, i don't go driving around in 2nd or 3rd gear at 7500rpm everywhere either. A few trips to the raised redline here and there aren't going to hurt.

No way in hell I'd run the vq37 up to 8000. Nissan set the soft limit at 7 grand for a reason... setting a hard limit at 7800 is probably ok...but no one way I'd stress an internally stock motor that far....especially for the barely noticeable effect on power delivery.
V6's in general aren't really made to rev that high, and the vhr has worse balance than most. If you wanna see 8 grand buy an s2000.

It's supposed to be a more global platform going forward, so speculation is it will be a little smaller. Probably closer to the size of the 99-04 model, which was fairly compact.

They probably need to cut the dimensions down if they are going to save 250 lbs too.

All you Mustang owners think alike :icon08:

Well it's the truth. You really are stretching it, and you said yourself you are concerned with reliability, so we are trying to help you out.

I know, I'm glad you do :tup:

that's because we're all real car enthusiasts...:icon23:

:werd:

blades-- I just know you are dd'ing the car and don't wanna get screwed.

:tup:

that would be a good size, not too big, not too small, but with the 5.0 it will be crazy fast (er).

agreed. the new edges were a pretty solid size.

:iagree:

Though now that I've gotten used to it I'm totally fine with the current size of the car. It would just be nice if it was a bit lighter.

lighter is always nicer. If they shrink it, it will be the only car you see running autocross :roflpuke2:

Guess I need to jump on the 5.0 bandwagon to get promoted to a real car enthusiast :roflpuke2:

I kinda wanna test drive one now. Not to buy, but just to see how it is.

Yeah but I'm trying to beat my 1/4 mile time too :icon17:

Want to have it reliable enough for a DD, but also trying to squeeze as much performance out of it as I can without spending tons of money. Makes it more enjoyable for the fun times, which is when I really enjoy the car for what it is.

For the fun factor, you should be more interested in the tune bumping up your low and mid range torque. That will be the biggest difference between stock tune and uprev.

Yeah I just look at the rev limiter bump to be a bonus. Seeing what my other options are with the UpRev and what I can do with it besides the obvious.
