Id also like to know what ur shifting at... i went a 13.1@103 letting out cuz i was scared of the driveshaft... that was also on a 80-something degree night, if not hotter... im confident i got a 12 in her as she sits but ima wait till i install my 2pc driveshaft...

 

Check the videos on the previous page

 

gotta love that stability control/traction control light haha. seems like 1-2 is about 6k, 2-3 is about that, 3-4 is around 5600.


hopefully you work it out, its definitely got more in it.

 

Did you get back to the track?

 

Haven't had the chance. Probably won't be until January before I have the time.

 

are you doing the tuning yourself? i was just wondering if you asked for any assistance from whipple for your issues, cause if they don`t know if the issues exists, then it will be a problem for those of us wanting to buy this kit in the future....

 

great question,whipple should be asking you for feedback and more than willing to at least share a tuning file even though you opted out of their tune, a hand held I am guessing???? did you ask who did there tune?

I have see all over the forums guys blowing driveshafts on dynos,why are you carefull about your OE 6sp shaft blowing on the track.I dont know the threshold,im just interested in your concern at what point can it come apart? is it due to TQ ,shaft speed,MPH.If I do something to add 100hp should I be worried???

 

Not trying to answer for him, but it's shaft speed. Stock shafts aren't balanced to handle the vibrations past a certain shaft rpm (i don't know what that rpm is, though) that usually equates to 100 mph give or take.

 

Generally speaking, the d/shaft is balanced for the speed rating on the factory tires, about 100mph.
you can take your driveshaft to a good drive train shop and have it balanced to a higher speed and maybe avoid disaster.
do a search, there is lot's of stuff on the forum,
steel vs aluminum, one piece or 2 piece
and the longer it is the worst it can be , depending on 1 or 2 piece
