In Reply to: What RPMs are you guys launching AT?? posted by M3 on April 29, 2000 at 11:53:29:

ratio for my Turbo, I found that launching at anything under 2800 RPM bogs me out while anything over 2900 RPM and I spin in 1st and 2nd (and a part of third if over 3300)-not much room!! This is at about 15psi boost with >100 octane fuel. I now have a remote boost controller which will allow me to launch at 5-6psi then switch to max boost when I shift to 2nd. I am hoping that this and my drag radials will allow me to launch at higher RPMs to avoid any bog.
