Cadillac CTS-V - Head/Cam Install Results with Video

I have had my car back for a couple of days and have been enjoying the new power. I'm a little dissapointed with the numbers; but the car feels strong and is fun to drive. The valvetrain noise is a little much; I am looking into yella terra roller rockers to address that.

Goods List:

Ligenfelter GT11 Cam - Idles like stock
Comp Chrome Moly Pushrods
PRC Stage 2.5 Heads
SLP Heavy Duty Oil Pump
Lucas 42.5lb Fuel Injectors
etc.


The video will give you good idea of how the car sounds while driving around the city.

that is such a little baby cam with a painfully high lift

Noy sure how I posted this here...moderators please move. Thanks.

What kind of duty cycle are you seeing on the injectors?

I am not sure; I have a question to the tuner on that now. Why do you ask?

Because my tuner (Slowhawk) that the stock injectors will be sufficient. He's going to see what kind of duty cycle he gets on my stock injectors, and if necessary, we'll swap in the 56 lb LS9 injectors that I purchased in preparation for my TVS2300 build.

I knew the stockers were going to be maxed out and decided on these. I will let you know what I find out.

I'm curious why you chose the GT11 cam. It's traditionally a sleeper cam in bigger motors with improved air flow mods. Right now you are restricting the cam with stock MAF, TB and intake. I believe the specs are 21*/23* , .63*/.64*and 119 LSA, hence the sleeper aspect. You can barely tell its cammed with such a wide lobe separation. This is a good increase in dynamic compression from stock, you just have to get better air flow. This is a good supercharger cam, just not sure why you wanted that high of lift. That is where all of your valvetrain noise is coming from right now. With only a 21* intake duration but .63* lift, that is a very fast ramp.

Did you do the work, or did a shop perform the install? Sounds great either way.

It is my dd and I wanted as close to a stock idle as possible. I am looking into a possible LSXr/Nick Wiiliams TB 102mm combo to address the air flow and Yella Terra Rockers to address the valvetrain noise.

Speed Inc. in Schaumburg, IL did the work.

Thanks.

Rockers aren't gonna do much for the noise

Hah. I moved from Barrington IL out to the east coast upon graduating college two years ago. Back then, I couldn't give a rip about cars, but I do remember seeing Speed Inc.

You have no idea what I'd do for a Lou Malnati's pizza right about now.

You could have still gotten away with a 228/232 cam and kept the idle near stockish. I'd understand if you had a blower but that gt11 is so teensy tiny. Hello, the stock ls6 cam is 207/217.

Concur. My cam is 223/236 .612/.610 115 LSA and although it's clear that the car has a beefier cam, I don't think it's that noticeable. See for yourself:

I know. I had 6 little pizzas shipped here for about $160. Had fun with the dry ice they packed in there, too. Threw a chunk of it the toilet and freaked out my girlfriend.

Yours is readily apparent that their is a cam installed; mine not at all. I like yours; but not what I was going for this time. Me and my "tiny" cam will have to due. I'm working on getting some more air in her.

Glad you got your Lou's; I'd hate to see anyone deprived of that ;)

OP you run this setup at all? Looking for results with that cam.
