RPM at the end of the 1/4

[turbojimmy]

Hi all,

I'm running 27" Hoosiers and 115 MPH at the end of the 1/4. This puts me at 5200-5300 RPM at the end. How much more MPH can I get out of this combo, or I guess how much more RPM do I have left? I'm locking the 3400 stall 9x11 at 90 MPH.

Thanks,
Jim
