The Highway Patrol are using the SS Camaro and HEMI Charger out in West Texas for patrol cars.

the D3 pics are cool. even have a shot of motor with heads off. just like the old days when you could work on motors in car without cursing the gods for no room. but i would be hesitant to take off top end of my new STS-V to do a little work. i assume the cts and sts both were going to be certified so the extra price for the warranty was factored in. would not want a new sts-v with no warranty. i see some folks refer to the blown cts-v as a cts-v2. 2nd gen?

Mike- not having read the guru's posts about the cai, I am guessing that would have been adding a cold air only, not being any performance upgrade. I am willing to say on the record that my car is FASTER/quicker. I did install the reprogramming module as well. I understand that changing the air/fuel ratio may even make a car slower, if it was previously optimized. I suppose you would have to be willing to believe a tuner that his dyno numbers are accurate and not influenced by other changes, but d3 has the numbers showing a 48 hp gain on an xlr-v.

I am also an old guy playing with my car and I do remember the quadrajet sound!! I still had one 2 years ago, and if you guys liked that sound you will also love the sound of the caddy supercharger. I have absolutely no use for an aftermarket exhaust these days (old remember), I do not want loud, but the supercharger sound is perfect. I once drove a hemi 40 miles to the track with open headers. I can't imagine doing something like that now. Mike

Mike that may be true for the STS, but the guru was specifically referring to the STS V, see his write-up here. The factory tries to balance performance with the noise, so it may be true about the 48 hp on the V, but I would be surprised, the guru seemed to imply that it was very free flowing stock

I dont care for a droning exhaust either, I want to be able to hear the stereo and talk

Mike, as for the air filters being under-hood on this application, they are in front of the radiator and somewhat isolated from the general under-hood heat. The serious applications have the filters ducted from the lower grill, something I am not willing to do at this time. A certain amount of cutting etc.. I may do later when and if I feel I can do it and still put it back stock and unnoticeable. For kicks i just weighed the parts removed-22 lbs. I bet that is worth about one billionth of a second in the quarter mile.:paint2: I was just awestruck by the weight. Pics follow of my car.

Pretty setup. Does this also give an aggressive intake sound and a louder supercharger whine? My V does not have much supercharger noise, but another one I tested had a loud blower. Now I wonder if it had been modified.

BBF -- you know I like the Guru's writeup; my impression is the quoted figures are for a tune and intake together, not just the intake. And his frame of reference is likely the NVH (noise, vibration, harshness) targets for Cadillac, not the aftermarket louder-is-better ethos.

Bruce I will have to go for a drive and listen particularly for the intake sound. I have been so smitten? by the supercharger sound that I really didn't pay attention to the air intake sound. I know that at idle and with light throttle acceleration their is NO additional noise. Just a caddy tooling around. Maybe a third of throttle u start hearing the whine. Mine was not noticeable previously.

Mike if you would, check out the d3 site and let me know what you think. I wonder if the article is 5 or 6 years old and things have progressed since. I personally think adding just the air filters would be a waste of money.

I just went to their site and they have no claim of hp increase with the basic cai setup, and the complete setup like I have states that a tune is required for proper performance. For what its worth the sts-v site claims 10 hp increase for the basic cai.

Mike, that is great that the intakes are in front of the radiator. Where is the PCM in that car? By the way, that is one beautiful car wow, I love the XLR. I didn't know you had the V, wow...

Ill check out the D3 site

Bruce, I am a little confused isnt the guru speaking of the stock intake?, Ill check his write up again

Yes, he considered the stock intake well designed and unlikely to require an aftermarket CAI. However, aftermarket CAI kits have been an attractive buy on the LC3 engine because when combined with aftermarket tuning they offer a HP boost.

Okay, it's official love the Cadillac Certified Pre-Owned Program Refueled.

* 2008 CADI STS-V

Most recent payment: $1,500.00

Received on: 05/14/2011

Got an email from Ally that my online access was ready, so I logged in to find that the CPO program just mailed in a check for the $1,500 jumpstart, as opposed to sending along one payment a month etc.

Cadillac is bolstering the program with competitive financing options. For May and June, Cadillac will cover the first three monthly payments on interest rates as low as 1.9 percent for qualified buyers.

Thanks Cadillac!

I may have to revise my opinion here. The D3 and Spectre intakes apparently offer higher flow (in CFM cubic feet per minute). In one test of the D3 intake this by itself allows another ~1 psi of supercharger boost and so adds some 10+ hp. Spectre says their intake with no reprogramming adds 44 whp (hp at the wheels). Still studying this topic for more info.

"THAT" would be something to seriously check out to see if true...

That would put you at over 500HP... :yupi3ti:
