i have a 99 stang with 3.73 in it, anyone no what the top speed is with these before ill blow them out and my tires fall off? someone told me like 130mph but i wanted to check here

 

If your engine is "mostly" stock then you will not overpower your rear gears

 

i have a bbk cold intake system, bbk headers with flowmaster system, performace chip and new pullys? will i blow the gears with haveing this stuff, and what do you think the top speed is. its also an automatic

 

Your top speed when racing (at WOT) is going to be determined by your gears and your tire size. You're not going to blow out the gears or the tires. You'll redline long before you do any damage to the rear end. I'm not sure what your tire size is, but my stock tires with 3.73 gears will cause me to redline in 3rd gear (1:1 ratio) at ~118 or so MPH. Anything past that and I'm into teh red and closing in od the rev limiter. Of course, that's at WOT. It's different when slowly accelerating because I would be able to use 4th gear then (which is something that you're not gonna do when at WOT.)

 

What do you mean by "blow the gears?" You aren't going to damage teh gears you have in there unless youhave some very unusual circumstances. They're not even close to the weakest link.

 

I had a kid tell me that he was driveing at about 120mph and his gears blew out and the rear end locked up and he almost hit a wall, which is what brought me to ask these questions on here, i have 285/40/17 on the back and 245/45/17 on the front, im just tring to find out if speed will kill me by my gears

 

he was probly low on fluid or something like that to lock up the rear end, or maybe a bearing seized. as stated above gears are definatly not the weak link!

 

well guys thank you very much for all your input and advice its greatly appreciated.
