if i remember reading JDI racing's thread about the VVT-I system in our vehicles, they can give us a low rev but yet create the same powerband as a higher reving vehicle for emissions and increase fuel economy? correct me if im wrong. but heres the link https://www.clublexus.com/forums/sho...d.php?t=114233

Was the gearbox cold?

I noticed if my gearbox is cold the lock-up on the torque converter does not work and will rev at 3500 @80mph. With the gearbox warm the lock-up is fine and ticks over at 2,900 @80mph

You think that's bad, my RX-8 is at 4,000 rpms at 80 mph.... and that's in 6th gear!


Quick Reply: My rpm was around 3500 rpm at 80 mph on gear 5, is that normal ?
