Hey all,
I've got a 2012 Cadillac CTS-V Coupe that I've raced at the Texas Mile in March '13, October '13, March '14 and soon again this October. The car is a 6-spd manual (t-6060) and currently puts down 600whp. The mods are 2.4 upper pulley, ported supercharger snout, lid spacer, CAI, long tube headers, cat-less X-pipe and ID850 injectors.
Thus far, my fastest speed has been 169mph (March '13) but that was with a healthy tailwind. That speed was achieved when the car was 100% showroom stock. Last March, 600whp, it ran 168.6 into a 15mph headwind so I'm expecting an improvement assuming more ideal conditions.
One issue that I ran into back in March was that my IAT2s were getting high enough at the 3/4 mile mark that the engine started to pull timing. This is normal for an LSA and occurs when IAT2s reach 140*. To address that, I will be upgrading the factory h/x and installing an ice box which should allow me to complete the full distance under full power due to keeping my IAT2s in check.
The only other mods I have planned for the event next month are taller rear tires, 315/40/19 Hoosier R6 and a ported LS7 throttle body. The tires should keep me from having to continue to shift into 6th gear (around 3/4 mile) as soon and the throttle body is larger than the factory one. Hopefully the larger tb will help with airflow and thus create more power.
The car seems to have two large issues which are weight, (+4300lbs) and an unfavorable drag coefficient of .036. That being said, it's my current weapon of choice and I love the car. So, I'll be making due with what I've got even though there may be better choices out there. That said, if anyone has any tips or advice for a newbie, feel free to share. I'm open to ideas and I'm looking for advice on how to maximize what I've got before I throw more money and hp at he car.
Thanks,
Jay
