YouTube - 2009 Hennessey Cadillac CTS-V Dyno Run:...

Here are the details: The V is an auto and has about 900 miles. Our V650 package includes: 4 inch cold air induction system, 1 7/8 stainless headers, high flow catalysts, upgraded midpipes with x-pipe flowing thru a stock rear section exhaust (reasonably quiet at cruising and idle, aggressive at wot), new billet supercharger pulley upgrade with modified blower snout (14 psi), 180 degree thermostat, re-programmed computer and intercooler system upgrade. OK, those are the general details and I am sure you guys will have a lot more specific questions about all this stuff.

Let me just say that we will do our best to post pics of these new items as we can. We will sell each item individually or you can buy a package from us. We also welcome any other shops or tuners to buy from us - we will take care of you. We are using the EFI Live software and have been very pleased with the results.

The V650 package will take a professional mechanic about 15 hours to install. Cost for the complete kit is $5,950 plus shipping. This is for a gain of 71 rear wheel hp and 60 rear wheel torque - these are peak gains over stock. At lower rpm's we are seeing closer to a 100 rw torque gain! You can really feel this in driving the car on the highway at part throttle.

We should have some 1/4 mile numbers soon.

What does the intercooler system upgrade consist of?

(I am assuming it is a larger front heat exchanger...)

i am still amazed to see the hp/tq curve for this car. Its so ideal and balanced.

correct. more details coming after we take some pics.

right now all i can tell you from a combination standpoint are all of the items listed in our V650 pacakge. some owners may want to mix and match parts and we have tested every combo. i can tell you that the heat exchanger upgrade does lower inlet air temps faster. we will be doing more testing on it soon to give you more info.

The car is so fun to drive. It is a night and day difference compared to stock.

Dave, I can' imagine the V being a real highway terror now. Low down traction is always an issue but at 60mph this thing must take off like a bat outta' hell.
