I have a BilletFlow 2.93 upper and Metco 4lb lower on my vert, and I consistently trap 115-116, in the 1/4. That's at full weight, as I'm not to big into removing half my interior just to run at the track.
There is not enough weight difference to effect the MPH by more than 1 or so.... Any pulley, CB, CAI, Tune Cobra should trap above 120, but alot dont.... Expect 116-118 depending on your driving ability.
Not to highjack the thread, but where are you guys racing 1/4 mile that they don't require a roll bar/cage in a 'vert? Ennis won't even let me register without one so I get to bang around the 1/8'er.
How about 11.86 @ 108 on MT ET drag radials (fuel and spark plug issues). Also had 119 mph on a 13.4 run using 285 F1 D3s. I should see a low 11s in the mid 120s with everything right this spring.

I run at a local track on test and tune days or on street car nights. I woud not even try it on a race day. I say it runs mid 13s, and then just join the mix.
I hope to be in the 11s with my new mods. One of the tracks that I run the 1/4 always grabs my light bar and then lets me run LOL But that was also runnig 12.0s. I am not sure what they will say once I break the 11s, This particular track is also an IMRA and not NMRA. I hope to run true street at Commerce in April, guess we'll see what they say1?
