Whats the deal...my car revs straight to 6250!!

[BlownStangGT]

I know most stock 5.0's like mine are not supose to rev straight to the rev limiter. My car is a freak of nature. Most 5.0's I know have problems revving and they seem to not all be there when they are stock, no one ever belioves me that my car revs straight to the rev limiter, I think I have an abnormally strong car...hm...anyways, can anyone explain this posisbly. If I am not paying attention and rem it in first it will hit the limiter if I dont pay attention, but people tell me there is no way possible with a stock motor, how comes my car does rev that hi? I dont think it has a cam, I bought it 5 years ago and the only thing it had was flomasters welded in place of the stock mufflers and no air silncer, i dont think the owne would have had the knowledge tio put a cam in since it was all stock, some people told me I could have 1.7 rockers....anyone know? I think its stock, just half a freak

My car hits 6grand pretty easy...

When I first bought my 5.0L Stang it was pretty much stock, and it reved cleanly past 6000RPM(Hit 6300RPM) Although I discovered that by accident twice. Once missed a shift, and the other time spinning in second it reved up so fast I didn't shift fast enough. (No I'm not a bad driver, I had just bought the car and had no experience) Anyway when your spinning or missing a shift like I did there is not as much load on the engine and there is alot of momentum so it should easily rev up that high without a problem. As for the rev limiter I don't even know when the computor start's cutting out spark on a 5.0L. Does anyone know?

I just installed Auto Meter tach and when the auto meter is at 5400 (wher I shift) the factory tach in the dash is bouncing off of 6500. Dont trust that factory gauge

Rev limiter on a stock mustang is 6250rpm.

You will notice that in first and second (especially if your car has gears) that you will hit 6,000 pretty quick. By third you will notice that once you hit 5K that it seems to take a lot longer for the engine to get to 6K (if you have stock intake). That's where the stock intake/heads start to hurt the engine's top end.

The factory rev limiter is at 6250rpm,and its not cutting spark its cuuting the fuel.

If stock cars couldn't hit the limiter at 6250, what would be the point of setting it there?

 

[eric88gt]

Any stock 5.0 will run to the rev limiter, the only problem is that it's not being very productive at that rpm.

 

[redterror302]

I have hit 6250 a number of times. Mostly by accident, but oh well. I hit it a few times while spinning around in a parking lot, and its not very hard for me to hit it in 1st or 2nd gear either.

Have you ever checked to see what gears are in it BlownStang? Just count how many times the drive shaft turns with one turn of the rear wheels. Dont forget to make sure they're both turning, and not just one side. 3.55's will turn the drive shaft a hair past 3 and a half turns, while 4.10's will turn the driveshaft a bit past 4 turns. I'm sure you might know this, but just in case some one else wanted to know how to do it.

2.73s in that mofo....with my autometer tach I cruised 70 at like 1750 or so, we checked before...Im getting 3.73s in june....its gonna be niutty!!!!!

Let's just say, if any of my cars DIDN'T hit the rev limiter when I floored it I would soon be tearing into it, to see what was broke!
Factory stangs give out around 5300-5500, taking it much past that will only slow you down.

My car will rev to the limiter instantly like it may as well be 3k. If i'm not paying close enough attention in 1st i'll tickle the limiter a little while shifting.

 

[2NDTIME]

They will all rev that high. The first time I went to the track I was shifting at 6k and my car ran 14.6-14.9 around 95. After I got to know my car and learned how to drive it to its potential I dropped shifting to around 5200 and dropped to 13.7 at 100.


Get it dynoed, that will show you how the power is falling off up there.

If they don't rev that high, something is wrong. What's unusual is for them to have the balls to hit that rpm in 5th gear, especially with stock rear gears.

Is that possible?

i remember reading something about the potential top speed of a stock Mustang with a 2.73 gear, i cant remember the facts but top speed would be something like 170+ if it werent for drag and the fact that the motor isnt powerful enough to push it that fast.
