I have 35s/4.88s and I blow the doors off of 4.10/stock tire trucks... I have a stick, not an auto... I spin 3550 @ 90 mph...

What is the point of you guys saying you turn x rpms at 90mph? How about a more useful speed like 60-70mph? I think most use 60mph as a standard, so even I should go back and check that and post.

Oh and are your speedometers recalibrated for the larger tires?

Well let me think of this for one second? well if we are doing that at 90 then the RPM's are alot lower at 70 I dont know where you drive but the speed limit here is 70. My speedo is recalibrated too.

If the ratio b/t tire and gear ratio are the same as stock then you don't need to re-calibrate the speedo for tire size.

For example on my truck, i had 4.10's and 35's so I recalibrated it correctly for that setup. But now with 5.13's and 38's it's pretty close to stock and now the speedo is wrong again.

60? 70? I live in California buddy... If you don't run atleast 80mph your getting run over by F350's on 44's on the freeway. I drive 90-100mph most any time I am on the freeway and traffic isn't stopped, and I still get passed by alot of cars.

It's not a matter of what speed you feel you gotta do...it's about getting a standard that everyone can relate to. And 90 certainly isn't it. I'm pretty sure the charts for re-gearing generally use 60mph as a standard.

You're missing the point.

I don't cruise around the highway doing 60 either. NJ, like CA, and probably every other state...if you're doing 65 (or posted speed limit) you better be in the right lane (doesn't happen!). People will easily get passed doing 80+mph on most highways.

But point being, to collect data you need to set up a standard. Else, everyone starts running off various points (2700RPMs @ 75mph / 2000RPMs @ 50mph / etc) and this doesn't help.

Or you could just multiply his 90 mph rpm's by 0.66666and have a very close aproximation of his 60 mph rpm's. Seems easier than argueing.
