what can I expect out of a 150 dry shot at the track. Right now the only mods to the car are true duals and a slp lid, spec3 clutch. Best time so far has been a 12.6@112 on street tires with m6 I won't be spraying out of the hole so slippage wont be very bad. Thanks

 

I don't know if this will help, but a 125 wet shot took me from a 13.5@103 to a 12.1@119. This was in a stock stalled auto with 555r's,lid,Loudmouth

 

Here is my results from a 100 wet shot,all stock .
13.2 @ 104 1.99 60ft stock n/a
12.3 @ 114 2.1 60ft F1 tires and all.

Seems to be 1 second and 10 mph for a 100 shot.
1 question though,a 150 DRY shot? What year car and how are you getting away with that much on a (stock????) fuel system?
Better make sure you don't lean out on that much of a dry shot. Wet kits are better(IMHO) for that much spray,unless it is set up for it, Bigger injectors-tuning etc.
Good luck and post your results.
