How fast am I going at 6500RPMs with 4:10s in 5th Curious to know how fast I was going last night. I was doing 6500 RPMS in 5th, I have stock 245/50/16.

Re: How fast am I going at 6500RPMs with 4:10s in 5th I wouldnt suggest doing that to much with 4.10's. The amount of friction your are creating inside the rear end with those 4.10's is unreal. I wouldnt doubt it if it was seeing temps close to or above 300 degrees.

Re: How fast am I going at 6500RPMs with 4:10s in 5th As a side note. It seems that many factory tachs are off by as much as 300 rpm (mine is). I'm not saying yours is wrong, it may be perfect. Sometimes the tach is not a very good speedometer (and sometimes it is). I'm fairly certain that you have plenty of horse power to turn that MPH.
Be safe!

Re: How fast am I going at 6500RPMs with 4:10s in 5th Hmm I calculated 161.9 mph. firechicken, I wouldn't worry about it with the 9 inch & 3.89 gears. NASCAR uses 9 inch rears and they run 200 mph. As you know I've had mine up to 161 with no problems and that's a 9 inch with 4.11s.

Thanks for the info. That's what I was thinking about doing. I just need to find a place to put it.

Re: How fast am I going at 6500RPMs with 4:10s in 5th There is PLENTY of room to tuck it under the rear bumper or to sides of of the bumper. With the built on fan you dont have to have it in the path of direct air flow. so you can even mount it facing the ground back there.

Just having cooling fins on the cover is not enough. the amount of heat your rear end generates at speed is extremely high.
