Cadillac songs

I have been on a music writing rodeo lately, so I figure I’ll slide in some Cadillac related songs.  Now of course I am not a professional song writer, or musician, or singer, so there are hurdles.  I like to think of it as having plenty of runway.

Cadillac has been a great meme for a lot of tunes already of course.  But since I am fascinated with  song writing, and I have an interest in all things Cadillac, it seems natural to mix the two.

Upbeat Blues numbers with a bit of swing appeal to me as tying to Cadillac’s roots and history while staying forward-looking.    I think my song Cadillac – Baby We Got a Problem manages that.  There is a lot of ground to explore; anything that helps get Cadillac further into the public eye and consideration seems additive for Cadillac and our community here at CaddyInfo.

If you have some Cadillac related songs or other art you would like to share with our CaddyInfo Community please let me know.

Stock Cadillac STS exhaust flow: 308 CFM

Found this interesting info graphic from a Corsa performance ad on a Lingenfelter site:

Corsa vs Stock Exhaust for Corsa 14157

 

The graphic shown is for the 14157 system versus the stock 2005 Cadillac STS system. This is particularly interesting for the STS-V since this is the same Corsa system that D3 sells for the STS-V.

The text notes: * Flow bench-tested 42.3 gain in exhaust flow vs. stock muffler.

This I read to mean that the graph is for flow through a single Corsa muffler versus a single stock muffler.  So in other words, the dual Corsa mufflers probably flow around 437 x 2 =874 CFM and the stock mufflers flow around 308 x 2 = 616 CFM.  Recall our target is 2.2 CFM/HP for 0 backpressure, so with a modified STS-V making 500 hp plus S/C load we would need 560 hp of exhaust or 560 x 2.2 = 1232 CFM.

I am guessing that the STS-V stock exhaust flow is similar to the STS stock exhaust flow.

We can see from the numbers then that the stock exhaust flow is insufficient, and that the Corsa’s are an improvement, but there is still some margin for further improvement.

 

Cadillac August 2011 CTS Sales up 39%

Good news — Cadillac sales overall were flat August 2011 compared to August 2010.   Why is that good news?  With the DTS discontinued, flat sales means that CTS and SRX sales have stepped up to hold the line until the XTS, ATS, and ELR arrive.

CTS sales blossomed at 5.8K for the month, a 39% month vs month, or 34% increase when the number of sales days are factored in.  SRX sales continued to show strength at 4.6K for the month.
