105 - 107 mph ?
what am i running in the 1/4 mile if im crossing at 105mph - 107mph?
i checked the ET database and didnt see anything relating to the trap speed.
the local drag strip doesnt have the times up but they do have the track open...

If I remember correctly hp=trap speed and torque=et. So it's hard to say. Where did you get the mph from. was it trap speed or was it your speed as you crossed the finish line and you just looked down at the speedo.

If your speedo is showing 105-107 when you cross the 1/4 mile then you are probably trapping 102-104. In an A4 with a decent hook (2.0 60' or better) that is bottom 13's.

That's an easier question to answer for A4 guys. I ran several passes of 13.2 to 13.4 @ 105. I also had a 13.1 @ 106 (2.0 60'). But that's for an auto with 3.23's so all I have to do is hit a decent launch and hold down the gas pedal.
M6's like yours will also have to factor shifting into the mix. But with decent conditions and a good driver the car is high 12's to low 13's. With most drivers (average skills) and or not so perfect racing conditions it'll be 13.3 to 13.6 I would think.

Trap speed is a correlation of a few things. One how your hp/torque curve is. If it's flat then you are going to have a lower trap speed than someone without a flat curve. Most forced induction cars will trap higher than a n/a engine that runs the same time. Trap speed also deals with traction. You can get a real good 60' and have a low et but also a fairly low trap speed. If you spin a lot then you will have a high trap speed.

I've since fixed a lot of that.
The 01, (identical stock form to the 00 except of course the LS6 intake & EGR) was putting down similar times the same day. After adding a lid it's best runs so far are mid/high 13s also trapping in the 103-104 range.
