Data logs?
Vids near the car to check suspension action?
E85 and meth spray.. When do you start the spray?
That vid is so far away, it's hard to tell what's going on. Appears to be REALLY lazy on the leave. Tune is? Spool slow? [Data logs should help w/ that determination.]

the turbo is lazy... just as it hits second gear the turbo really comes to life about 150ft out
Lots of potential! Nice build.
I called Jakes for the first time a few days ago, left a message and Jake called me back that afternoon. Try leaving a voicemail if you haven't been. Good luck

Oh yea , something is off . Leaving on 5 psi with a t4 and a .96 a/r that thing should be obliterating the tires . Should really look at the tune . Definitely shouldn't be lazy at all .

Yes the car is intercooled big procharger cooler, rated at 1300hp
on the sat day event i was seeing 60deg iat at the 1/8 mile on a 92deg day
Congrats Kent! Very nice mph! So it was making 20 psi on those passes?
You're on the right track with a trans brake. Rossler in another option too. No turbo car should be without one! You need to be launching that thing on 10-12 psi (or more) so it can 60ft. A 2 step would be helpful too to get it spooled on a 5.3 and control your launch rpm.

Very happy with the mph on the car, the 10.2comp 365 forged engine will fly when i get this lil 5.3 dialed in.
