First trip to the track, followed by first flatbed ride

Filed under: 2005 Cadillac CTS-V (Caddy)

Took the car to the local "test n tune" night here, first one of the year. Really hot out 29c and an effective Air Density of 5400ft. Did 5-6 runs kinda trouble free... A few wheel hop starts, one slow shift. But came out with a 13.5 @105 as a best (corrects to about 12.7 @112 at sea level).

Then I went for a run with the traction control turned off because I could feel it hurting me in the 2-3 shift where even if I had a touch of spin it would have been quicker then the tc kickin in and dropping the revs. Anyways launching with the tc off proved to produce the most wheel hop of the night, followed by a loud BANG. It then felt like I wasnt in gear but I was, I then realized I just blew the rear end.

No biggie really, I 1/2 expected it, this car had not been babied by me or the previous owner. It just sucks having an audience for such an event, then I sat for a couple hours for the flatbed tow truck to come get me from the parking lot.

Now it sits.... awaiting my decision.... put it together with another stock rear end or build it bullet-proof? I'm leaning towards the latter.

Dyno #'s

So a couple months ago I took the Cady to a Dyno for base numbers, to see what its got as I bought it.

420hp 361tq, kinda low on the tq for being S/C'd but oh well.

In talking to the originator of the tune on the car he said that was over a 2yr old tune and he's made leaps and bounds since.

So I purchased a second PCM for him to reflash with his new tune, and had it swaped in a couple weeks ago.

This morning I just got the new tune Re-Dyno'd with nice gains, 40hp and 40tq

460HP 403TQ at the rear wheels.... still through the stock exhaust, and thats the next thing to go.

Then this "Huge" 3.0" pulley needs a diet :)

Got Fuel?

350km trip, each way.

Spirited driving, playing with a few vehicles on the road, constant W.O.T..... Whole tank of gas GONE!

15mins of "rabbit chasing", gave up cruise set at 125kmh, arrive home 1/2 tank used.

Moral of the story, Heavy right foot = lotsa dead dinosaurs go to "waste"
