1/4 mile times

to start. Do not spend 2k on a verter. I had a custon built 9in stalling near 5k that is bullet proof that only cost me 950. If you want to change your gears post your specs (tire height, spool/grip/ open, 1/4 trap RPM, track/ street %, ect...)
what size is you fuel line now? i dont think you need a bigger line.
If you want to dump money i think a new 400 dollar verter with more stall and a bigger cam with near 550 to 575 lift with a low durration would help. But toon what you have with whats left of the season the make small changes in the off season.
