First 9 second 1/4 Mile Pass, 9.97 at 140 mph Edition 1 Coupe
I ran my car at Beech Bend Raceway Park in Bowling Green Kentucky last weekend. The track was not prepped for street cars because they were doing bracket racing with a big payout and just needed consistency so traction was an issue, but I will try again on a better prepped surface in a couple weeks and hopefully get deeper into the 9s.
Quick mod list:
YP4 Turbos
3" downpipes
AWE Track exhaust
CF Air intakes
Comp Spec Cooling System
AEM Meth injection
Wavetrac LSD
2.65 Final Drive Ratio
Stock transmission tuned for more line pressure
stock engine internals
305/35/18 MT ET Street Drag Radials on CCW wheels
Full Interior
Fuel was 93 octane blended with 110 Renegade

Awesome achievement, congratulations!
Now it's time to race Brooks in his McLaren 720S!

Silly question, but I will answer it anyway. No nitrous is necessary to make 1000 bhp out of the m177 when using twin 58/76 turbos and no nitrous is being used. The car that went down the track is the same car that I drive to the store or to work, same tune, same weight, same power adder.

Through tuning we were able to achieve more transmission line pressure at WOT to hold more pressure on the clutch packs. The result is zero slipping and a big increase in torque capacity. There is no sacrifice in drivability because at lower throttle and load values the transmission is still running stock pressure. Just quicker Full throttle shifts and increased torque capacity.

Awesome. I heard a while back something similar from Andrew (power technik) about increasing the trans line pressure through tuning. Who did the TCU tune for you? And my understanding is it has to be loaded on-site as the TCU is located on the trans itself? Would love to see if the shop who did this for you sells the tune file that you could then load onto your vehicle locally...

And there are only a handful of people on this earth that can do it

Its definitely a fast pass but I can't help wonder why a 2.65 final was chosen ? Usually most would run in the 3. something rather than go down in the mid 2's . With my race car ( a 5.0 mustang ) I ran 4.11's with tall tires , making 1260 hp and ran mid 8's at 164 mph . Was the car more set up for 1/2 mile ?

I'm thinking the taller diff ratio was selected to reduce wheel spin and improve traction because of the torque levels, also would give higher terminal speeds

Taller diff ratio was so he passes the line in 4th gear instead of 5th gear

How do you like the YB4 turbos? I see many customers with great results. Do you have more photos of them on the car?
Do you think there is more left in improving your times? Have you thought about reducing weight? I know here in Gulf we can have option of light weight seats and so on.
Great job once again. First and only 9 second c63.
