V8 Highway RPMs?

[kylebacc]

OHHHH ok Chris. I worked it out now. For some reason I read your post the first time as saying that at corrected 80 I should be at 24-2500 rpms. I don't know why. Now what you're saying makes more sense.

Also, you do think because of the S/C I could go with about the same or a few less RPMs (as opposed to what you said for others, a little more)? Because I'm fairly confident I'll have enough torque to not need to worry about wind, hills, etc (within reason, of course).

I just looked at your t-case ratio calculator... Good stuff. I did ok for swaggin' numbers in head
:cheers:

Haha I just did it too and returned right away to tell you that. Guess you beat me to it! :flipoff: Thanks a lot for your help. And everyone else. I guess I'll try hunt for some 4.27's. Didn't realize they made those. I don't know a whole lot about gears. Can you tell??

:cheers:

EDIT: I guess since I have a Toyota I'll be hunting for 4.30 gears?

One last thing... If you do get the gears makes sure they put in the 'solid spacer' when the gears go in.

The stock design spacer can crush and cause diff failure on big tired, high torque applications. This is one of several threads that references it, read shabaka's post at the bottom of the page. truetrac, LSD, ATRAC, TRAC - Toyota 120 Platforms Forum

Many of the 3rd gen e-lockers, Diesel Prado rears and some others have had failures probably wouldn't of occurred if it had been a solid spacer from day 1. It's a very low-cost 'hardware' component.

Got it. Thanks for the tip and the link. I have been reading up on the gearing thing and the solid spacer seems to be a reoccurring theme. I will make sure to get them (it?). Do I need it for the front too? And now that I think about it, how does my ARB rear locker come into play? Are the lockers universal to the gears? Or do I have to get a new one to match the new gears? Sorry for the seemingly obvious questions.

 

[CJ3Flyr]

I believe it applies to the front also even though the front doesn't seem to have issues. Given you have the ARB you probably already have the solid spacer, it is worth confirming though.

As far as gears go it shouldn't make a difference. The ARB setup retains the stock ring & pinon gear unless the person chooses to change the gear ratio.

Cool, thanks a lot.
