Mark
purchased this beautiful 2003 Cobra brand new and has taken it through several
different configurations in search of his ultimate ride. Most recently,
Mark moved up from a Whipple supercharger to the HP Stage II TwinTurbo, and the
results are incredible. The car was tuned at Performance Dyno @ 15 psi
with 11.5:1 A/F ratio and 16° timing.
"Just turned 1000 miles on this
new VT Darton 324 and decided to get a baseline dyno. Here are the specs:
15psi
93 octane
16 degrees of timing
I was kind of in a rush so I was only able to do a little tuning on this car but
I wasn't there to make a number. I was more interested in getting a feel for the
new setup and getting some experience tuning a turbo mod motor.
So, here are the results: 739.62rwhp/700.05rwtq SAE
Don't forget, this motor is tight (only has 1000 miles on it). Also, it needs
more timing down low before the boost kicks in to increase the torque. This will
help a lot. I don't see any reason why this combination can't hit 800rwhp SAE on
15psi and pump gas." - Mark Chiapetta

SAE @ 15psi on pump gas !!!
"For fun, I attached a dyno
graph of my car with the three different power adders that it's had throughout
it's life. The first run is the stock motor with unported Eaton running 16psi.
The next run is the stock motor with Whipple at 16psi. The third is the VT 324
with crower stage2 cams and twin T-57s. Enjoy this one!"
