13.5 ...IF IT HOOKS
you didnt mention an intercooler so assume thats stock ... if so i seriously doubt youll finish the 1/4 with the boost at 17 without some octane in the tank or youll see knock shutting down the run and maybe it will be in the 15s

I'd say at least 13.3 I ran a 13.3@100 with similar mods on old good year gsa's had a 2.0 60ft, left at zero boost. It just hooked and went, that was @16-17lbs boost. That was my first and only run down the strip...so far, I've got some updated stuff so I'll be back to the track hopefully this year...Mike
13.1 with good tires,good driver with 1.6/1.7 60fts,cold air.14.50 regular tires, average driver,computer pulling timing,2.1 60fts
1 thing = RACE fuel .. turn the boost up.. if you have tires it will run 12's all day .. they aren't even the same car on higher boost

You have the combo to hit 12's But like everyone said its not gonna happen at 17# of boost on street tires, get an alky kit, a tuner, and some MT dr's and run out the stock turbo at 22#s or put on a te-44 and reach it much easier...and practice.

I will say 12.99 with some really good tires. I have run a 13.8 @ 94 with a peg leg rear end, Bald street tires, FP, AFPR, 50lb injectors, TT chip, ATR exhaust, and k&n filter on a 135,000 mile car.

The quality of the headwork is where you may get into the 12's on a stock setup. I never could in my stock GN, I ran best of 13.007 at 104 on pump gas, only had a chip, injectors, gutted cat, FPreg, hotwired redsXP pump and 28x9 slicks at 3710#'s. One time I added race gas and set the boost at 25. My 60 foot went from 1.8 to 1.6... so it was an easy 12 sec pass with that setup all else equal. I'd say just add alkycontrol and a new TT alky chip and run 12's "easily"

What was your boost?

Just for reference, my old 86 GN went 12.8@108 on a 1.8ish 60' (open rear) with just a gutted cat, 237 regulator, k&n cone filter, race chip, race gas and slicks. Boost was at around 22psi.
With your mods, traction, and race gas (or alky) you should be solid mid-low 12's.
