i've had my 2.3L whipple since march 2008 in my 2007 mustang GT. i got it thru Jared at Lethalperformance, thats a great place to get mods from. anyways, my whipple is doing great, no problems with it at all, except some belt slip and pulley squeal on the accessory pullies not the whipple, but i fixed that with a 8 rib belt upgrade.
the other mods on my 2007 GT are:
whipple 2.3L SC
BBK LT's and o/r x pipe
MBRP muffler deletes
pypes M80 mid mounted mufflers
CF DF clutch and CF steel flywheel
spydershaft 4" aluminum 1 piece DS
TA performance rear end girdle
FRPP 4.10 gears
pro 5.0 ST shifter
8 rib BGG performance kit
thumprrr tensioner
SOS triple gauge pod
innovate WB a/f gauge
autometer z series elec fuel pressure gauge
autometer z series mech boost gauge
20" shelby razors
and i think thats it
i'll post pics later
