No tune yet. Will be dyno & street tuned by John Vega of after the 1st ofthe year.

Full boost at 2200 rpm. Pulls real hard. Not much traction in 1st & 2nd at full throttle. Would expect whp to be in the 220-230hp range when tuned properly. Extremely fun to drive.

spools to 22psi at 3800, from 5800 up I set it to gradually increase to 24psi by 7200 (only in 4th and 5th gear. lower gears are set lower for traction purposes)

[Dyno Tune]
435whp 390tq at above mentioned boost.
I've made 420tq, but kept breaking gears so I lowered the boost in midrange to lower the peak torque below 400 and save my trans.

1funryd traction bar with skid bar and front torque mount - insane improvement in traction and reduction in wheelhop! so much more room for activites too! and best possible protection for the oil pan and exhaust
Motive Force Performance motor mounts- eliminated all remaining wheelhop
custom lightweight bumper supports
Sunroof assembly removed, Custom aluminum plate to seal the roof
Megan coilovers
shortened shifter

current record so far:
11.69 @123mph with a worn out clutch slipping every single gear. Couldn't even go full throttle until I was over 90mph.
Aiming for tens in 2019

[Future Plans]
mawr powa, duh
Bigger cams
bigger compressor wheel
bigger injectors
custom fuel rail
fresh engine with higher compression
Alum race seats
Aluminum exhaust for the street
more weight reduction
6pt cage
race harness
