Just raced this weekend with 03 cobra. Street pulley with 538 HP.
Launched at 3000 RPM and bogged horribly. Also having trouble with 2nd to 3rd.
60 foot times of 2.0, quarter mile at 12.2 at 118mph.
I know the car does alot better than that. Has polyurethane bushings, hard launch kit, Drag...
Just raced this weekend with 03 cobra.
Have the street pulley with the blowzilla with 535 HP
Poly bushings, hard launch kit and drag radials.
Heated them up good and launched at 3000, it bogged horribly and turned a 2.0 sixty foot time.
Could I potentially launch at higher than 5000?
Still...

600rwhp, 19psu pulley, 70 degrees, medium humidity:

Doesn't this seem a little low with the horsepower these two pullies give us? Thought we might be...
Just got the KB installed and tuned. With 19lb pulley, 600 RWP
With 13lb. got 530 RWP.
We have already broken half shafts when the car was stock at the race track. It will be raced more now. What next with this overabundance?
Just had the Blowzilla installed, on the dyno with the 13 lbs. pulley, it pulled 500 hp and 460 lbs. of torque. When the 19 lbs. pulley was installed it would slip at 5000 rpms. With the highest horsepower at 560 hp and 550 lbs. of torque.
What should be done to our pulley setup to eliminate...
Just got home from racing today with bad times. Last week we broke the half shaft and had it replaced under warranty. Picked up car, and raced today.
Stock cobra, 23lbs. tire pressure, taking off at 1200rpms, speed shifting:

Have an 01 Lightning with mods. Best times of 12.6s. Lately, after warming up the tires in the water (Nitto 555) the truck acts like it is flooded and will ocassionaly die. After restarting it, it idles terrible. Put it in neutral and clean it out a bit and it will either run better or act...
Ran the cobra for the first time today and broke half shaft.
Only took off at 1500-2000 rpm. Made sure TC was off.
Not sure how it happened. Should I have not givin it full throttle off the bottom? Not sure how it happened so easily. The car is bone stock with 570miles on it. Is this...
Just wondering what the purpose of buying a pulley kit with three different interchangeable pulleys are for?
If I am changing the pulley to get the most power, is there a reason that I should be changing it out again?
I guess what I am asking is, should I only be driving around with one pulley...
Just bought 03 Cobra and haven't got it to the track yet.
Can anyone tell me what to do with the traction control? On or off? Also, with the car being stock and under 2000 miles, what RPMs should I be shifting at?
Revrun
Just got new cobra. Never raced a new stick at the track, wondering what to do with the traction control? on or off?
