Need help with why my 1/8 MPH is so low compared to my 1/4 MPH.
As you can see I go 107 in the 1/8 and 148 in 1/4 and this is missing 3rd gear on this run. Any ideas whats going on. (Car 187)

 

Early shifts.

 

Banging the limiter before shifting? What rpm are you shifting at? Log your shift times to see if your shifting too slow and falling out of boost between gears? Could be a multitude of issues. Need more data.

 

Yeah in the video you can hear me bang the rev in first gear. Car is set at 9250 only cause the tranny is stock gear rations and I need the RPM for 4th gear. I am going to try to short shift firat gear next time to avoid hitting rev.
