Hi,

I'm currently in the process of putting a V8 from a Vq into my Vl. The transmission is a Turbo 700. I am about to buy some bits to rebuild the Vl Turbo 3.45 ratio diff that I will be fitting.

I'm wondering what sort of RPM you guys with V8's are seeing at 100kph?

I have an opportunity to put some 3.7 gears in the diff, any ideas what sort of RPM at 100kph this would give?

Thanks

there are calculators on the net that give you answers. I have a 3.45 and it sits around 2,000 rpm at 100kmh. fuel usage is pretty good, i don't think it uses any more than having a 3.08 as it's not under load.
