Closest guess wins!
I'm taking my personal 2012 Shelby GT500 to Brenspeed next week to get the following done to it.
SHELBY GT500 2.60 PULLEY SET
SHELBY GT500 AUX. IDLER PULLEY 90mm
NGK TR6 SPARK PLUG
2010-12 GT500 JLT PLASTIC BIG AIR 123MM CAI
The only prior mods are 3.73 gears and Roush Axle-back exhaust.
You have to guess the peak HP after the dyno. The closest guess gets a free shirt! Sizes are S, M, L, XL, 2X, 3X
These are the shirt designs you can choose from.
If two people place the same guess, the first person in will win. Each person may guess only once. Just update the list periodically. Guesses will not be allowed after 5:00pm Tuesday the 11th. Go!
