Spraying Lt1

i was just wondering if this seems possible.
-say i have a low mile lt1 with basically stock around 285RWHP/311RWTQ
-if i where to upgrade the injectors/fuel pump with a wet kit and spray a 125 shot and had it dyno tunes perfectly will it be possible to put down over 400RWHP???and perhaps with the right rear-end/suspension go into the 11's???

thanks.

First off, a wet kit doesn't need a change in injectors. Fuel is added through the same nozzle that the nitrous flows through (hense the name WET kit).

I have a friend with a stock LT1 with CAI and a cat back system. With a 150 shot and a set of borrowed ET Streets, he ran a consistant 11.6.
