Last week I drove 6 hours to get to Razors Edge Motorsports in Margate Florida where I spent the day with Tim and Paul of Razors Edge and Chris Johnson ( a good friend and owner of Superchips Custom Tuning ). Chris Johnson was doing the tune on the car. Tim and Paul meticulously installed the Whipple, the install and care of the car was top notch, second to none. Car covers were used, and all equipment installed was done so with aesthetics in mind without ANY prompting from me. Paul takes a lot of pride in his work.
The car is running at 17.5 pounds of boost, and Chris had the car tuned completely in 2 pulls. We made a third pull to add one degree of timing. The car was tuned ULTRA Conservatively as per my instructions, let me just state this before we go any further, I sacraficed a LOT of Dyno HP numbers to make the car as safe as possible. Also, the car was TUNED AT FULL OPERATING TEMPERATURE. This is a daily driver, I live in Florida, I want the car to show true accurate numbers of what it will do in the real world. Period. The numbers shown are from a Mustang Dynamometer, NOT a dynojet, therefore the conversion should be 10% to 15% higher to get the Dynojet numbers. I believe this would put it in the 605 / 610hp range as per Dynojet specs? I really dont know the answer to that one.
So with the car at its max running temperature, total heat soak ( no cool down on the final pull ), we pulled down 532hp / 587tq with the temperature gauge pointing straight up. I do not know what the conversion would be to a Dynojet, and with that said, I do not know what the conversion would be if we ran the car on a Dynojet with it completely cooled off. I suspect it would be dramatically different.
This car runs like an absolute animal. I managed to tangle with 3 people on the highway on the drive home, wide open area, nothing but trees around for the record. The closest car was about 20+ car lengths back within a few seconds, and I did nothing more that just press the gas in sixth gear only. I never downshifted on any occasion.
Many thanks to Paul, Tim, and Chris Johnson. Keith is a great mechanic there, and REALLY knows his stuff. I am now compiling a mini video of the processes that occured while there, and am attaching some of the dyno information as well.
Would I recommend the Whipple to other Cobra owners? You Better Believe It...
1st and Second gear... gone, forget about it. 3rd is like a stock cobras first gear on steroids, 4th is the never ending bye bye Z06 gear ( exaggerant explanation but fun none the less ). Fifth and Sixth are great highway gears, and they work wonders for killing ricers and imports by a few dozen car lengths with nothing more than a slight press on the gas pedal. Vector, and Wilson knows what I mean about that
Ok, as for the mods, that same day Razors Edge installed the following:

Ok, as for the mods, that same day Razors Edge installed the following:
- 60lb injectors from Performance Fuel Systems ( Alan Kennedy had those injectors flowed and matched prior to installing them ). The highest 2 flowing injectors went to pistons 7 and 8
- Accufab Throttle Body
- MSD Boost A Pump
- NGK TR6's ( .28 gap )
- Superchips Custom Tuning "Big Air" MAF
- Superchips Custom Tune by Chris Johnson
