Less weight always helps

I thought it was best not to shift past 4th in the 1/4 in these trucks? Or do you run out of rpm and gear and have to shift to 5th?

Nice Henry!! Good to see you getting the results you worked so hard for. Can't wait (hoping) to see future results with Twins!!:coolspot:

Unless you have an extremely slow truck or extremely large tires you will definately need to shift to 5th in the 1/4. If you shift at 3500 RPM you will hit 5th at about 90mph on 32" tires. On 32" tires 107mph puts you around 3100 RPM in 5th. On 28" tires like what Henry has 107mph puts you around 3700 RPM in 5th, and he is going alot faster than 107. As long as he still makes good power over 4000 RPM he can likely get a better ET by not hitting 6th.

I see.. So just put it in Manual and put select 5th gear and let her rip??
