i have a 01 mustang gt with super 40 flowmaster exhaust, k&n fipk kit, hypertech programmer

how much horse power to the wheel am i putting out, my fastest time at the tracks is 14.45

i have about $ 250, what should i buy first to drop my et (cheapest horsepower) or should i just save for rear gears

 

i would guess about 250 maybe. i would look at some pullies or a throttlebody and upper intake.

 

About 10-30 RWHP more that stock would be my guess.

 

about 245rwhp... get the gears. 3.73 if 5spd ... 4.10 if auto

 

The best mod to drop your ET would be a set of drag radials. They will help a little now and a lot later on down the road.

 

definately save 4 gears

 

i would save for gears or as JD1969 said, DRs,

a good set of tires will let u launch the car and use its true potential

 

Gears, no doubt about it. Single most dramatic change in the cars performance will come from a gear change. I image your year and model would have stock 3.27's. Depending on your tranny and what your main cruising use is, 3.73's or 4.10's would be best. 4.30's just manage to make your first gear (or two) basically worthless and contributes to many replaced tires. 4.30's also tend to put a huge strain on your whole engine over time. You'd definitely need drag tires of somekind with the 4.30's as well. Little or no traction with anything less. Save for the gears.

 

You Probally have about 25 HP added now. With having only $250 get rear end gears. Do not get 3:72 they won't help with out DOT slicks, get 4:10's they will drop the ET into the mid 13's
