This might be a silly question, but I know that my 2004 SVT Cobra has a RPM limit of 6,500. Can someone explain to me what the car does if you try to exceed that limit. Is this change at 6,500 a timing change, or a fuel flow change or what?? What happens if you just keep your foot to the floor at 6,500? Actually, I haven't revved up that high before, but I read that a governor of some sort cuts in at the 6,500 limit. How does that all work. Thanks for the help....
The computer Rev Limiter is set at 6800 but can be bypassed with a flash tuner like the Predator and SCT as well as a custom tune! Many guys shift at or above 7K at the Dragstrip!
Unless your motor is built and with alot of mods, your wasting time at anything above 6200. My tuner guy said 6000 was plenty unless you have some major mods.

This is not true . take your car to a real road race track where you will go 160 mph
I made shifts at 7k rpms, You will to when a z06 is on your a$$
The car pulled right through to 7k.
I would never do this on the street but when you start racing these things you will
Your tuner is telling you that because you must be a street racer

A dyno tune will show you where you are making max power to the wheels. that's how i determine when to shift my car, also to set my shift lite. Anything over that is wasting time and slowing down.
Also don't bounce your rev limiter to much, that's how the FPMS craps out on these cars.

You must be smarter than a dyno. It tells you where you are making your best power and where a good shift point is. Anyone that has any racing background and anyone with any sense knows turning a stock street motor 7K when its not making power there doesn't deserve to even own it. Futhermore, a Z06 will eat you for lunch. I see alot of bull in your statement.

Its not a drag racing. Its Cal speedway a nascar track. And yes road racing over rev is used alot. Not perfect shift points. Just because your car makes the most power in one spot does not mean you will win a race if you shift in the spot. Sometime you are turning right at your perfect "dyno" spot to shift. And yes I did pass z06 vettes.
And the 7 k is what the tach said. Who really knows how close it was, but its not to far off. So where is the bull?

What difference does it make whether you race on the street, a drag strip or a road course? You make power at certain rpms. I don't doubt that you are substaining a constant speed at 7K but from you remark, you think that a "street racer" doesn't know how to drive therefore not knowing where to shift... whether or not this is what you meant... this is the way it comes off to others that read this.

This is how I took it but thought I would stay out of it... but I just can't. lol. My cousin bought a Z06 3 months ago. (I should have been a doctor as well ). A Z06 weighs less, has better handling, more power (unless your really mod.) and better aerodynamics and a much higher top end. How is this possible unless this guy just can't drive. With all due respect, if your out running him, the more power to you brother! Way to go. But I can see why he is calling bull as well. Drag/street and track is alot different so you both know what has to be done to win your type of race.

There is major differences between street and a road course. And yes if you have never been on a road course or to a driving class you most likely think you can drive until you attend, after you do you will see just how much you dont know about driving. I run slicks on my car with coil overs all the way around. The car has been scaled and set up for road racing . If you don't believe me about passing z06s. I don't really care. It did happen.
A 2005 z06 is 505 hp at the flywheel the car weights almost 3200 lbs thats 415 rwhp my car scaled at 3562 and dynoed at 456 rwhp coil overs , slicks, dtc hawk pads and a better drive 100% possible!
I also rode in a car that was in the TT time trials and the racer rev his car so high in the red I could not believe it. His car was a spec miata with a stock motor and suspension. The car red lined at 7k ,I think might have been 8k, he did not shift until his tach was in the 9ks at times.

these were early 2000s I never said they were 2010s
As my car heated up they would stay with me but I was still in front. When my car was just a few laps on the track I could pull away from them. Thats what sucks about super chargers

At first, you said you were outrunning Z06's. That opens the door to any Z06. Where the new ones are concerned, I called bull and thats why. Still, if your in front of any vette, then your doing the mustang name proud.

limp can tell you what happens over 6500rpm because he races at this point. These motor are tuff but turning one like this alot will result in a blown motor in a much shorter amount of time. If money is no object, let it rip.
the car never hit the rev limiter but the tach said 7k rpm. Its not like i held it there thinking thats fine. It just hit 7k rpm a few times while racing.

Maximum RPM's on an '04 SVT Cobra
