Hello,

I see this question has been asked before but technology in this field seems to be constantly changing so I figured i would inquire once more.

A guy in my area who has been doing work on LS engines for the last decade decided to open a small shop. I was quoted a fair price on install so I am considering having it done.

I have a 2005 C6 Z51 M6. The car is bone stock with the exception of high flow cats and a Magnaflow exhaust. Over the winter I will be installing a set of full length headers. My goal is to eventually install a supercharger; although my plans always seem to change and this car is constantly evolving (I have many body mods). I am not doing gears. The car is a daily driver, and I like to take long trips in it. I really appreciate the smooth ride on the highway and easy passing on sixth gear. I would hate to have a car that shakes and surges constantly, and shutters when passing in sixth. On the other hand, the one thing that drives me crazy about this car is how it sounds like it has no *****. My father has a 2004 ZO6... The LS6 sounds so much better and the power band is so much more enjoyable.

I am considering the Texas Speed 224R Camshaft. I also looked at the LG executive cam series and although they seem to be turning out some decent power, the idle is not much different than stock in my opinion. I am looking to pickup some torque and hp... have a little more of a noticeably aggressive sound... but still retain stock drivability....

Thoughts?

A couple of recent threads discussed this. "The 100 hp bolt on receipe" and "what type of cam" both covered what you're asking. I'd link it for you, but I'm pretty low tech when it comes to computers. Read those and I'm sure there are others. If those don't answer your questions, come back and ask. Lots of savvy folks here

If you know you're going f/i, I'd get something a little different than the 224R. I have a 219/231 .607/.617 115lsa cam that I like a lot. Mean idle and great manners. Plays nice with a blower too.

 

How close is the supercharger from happening? That will play into the cam selection unless you plan on replacing the cam again. The Lingenfelter GT-11 is a great choice and a friend of mine has this cam in his 2005 C6 M6. The low and mid range torque is great. The car starts and sounds great with no bucking/surging. I have driven the Vette and very smooth.

 

My thought is have a custom cam ground for your application. The cost is the same.

 

SNL VB cam would be a mild cam in a 6.0L and works well with the blower down the road. It's a 22x/23x on a 115 and will have an ever so slight lope at idle just to let you know it's not stock under the hood. Yet it has a negative overlap, so it will have smooth driveability. Feel free to call me with any questions.

 

Let me help..
OP - I just went through the same thing, and my cam will be installed later this week. Read this.. In my thread (the first one), I list the specs of the cam I am installing and why. Basically, driving on the street is more important to me than driving on the track...

Alot of really good posts here. Thanks for the input guys,

Well the supercharger was set to be installed sometime around Jan-Feb of 2012. I take the car off the road for the winter. I had a cowl hood installed to fit it. Generally I am just looking for more power. The car is already a blast to drive but i have had it a few years, and would like to go faster. I have no horsepower or torque goals. I find when you set a goal like that you are constantly throwing money at the car and never really happy. I have been happy with the stock LS2 for years, I am just looking to add some sound and a little kick in the pants to improve the fun factor. Supercharger is an expensive proposition, and I don't know what's coming along down the road. I am the type of guy... if I found a good deal on a nitrous setup or turbo's I would change horses mid race. Not the best idea for someone who is looking for a specific power goal. I figure the stock cam is junk ANYTHING is an improvement, I don't necessarily have to specifically Taylor a cam to a specific blower.

Again, not looking to squeeze every little drop of performance out of the car. If one cam made 30hp and i could order it off the shelf and a custom one made 33hp... it would make no difference to me.

In addition, I am not cam savvy, and haven't gotten involved in this type of modification since 2004. I am personally not even installing it. So my best bet is to stick with something tried and true.


I think we are on the same page... I will have to follow your threads.

I'm not trying to squeeze every last drop of performannce out of my car also. I want more RPM, more HP ...performance. But I'm not willing to give up the ability to go on a 4000 mile road trip and be happy. I dont want a cam where I'll need to change out the springs all the time. I have no problem leaving a few HP on the table to keep my car civil. Although, I did set a goal...Z06 power with stock reliability

 

So did you swap out the cam... and if so to which one... and how do you like it?

DG

 

OP: Here is the cam spec that I have in my 07 Z51 A6.
COMP CAMS LS2 CAMSHAFT (220/224, .581/.581, 113 LSA)
Overall I am happy with it, my car is a DD with over 115,000 miles on it.

Good luck with your build!

 

What numbers did you get out of this cam and what other supporting mods you got?

 

416 rwhp & 398 rwtq - All mods are listed in my profile. I still have the stock intake manifold, which is not ported.

 

Based on you mods that HP seems a little low. I would have thought you would be at about 430.
I would bet a Fast 102 will make a big difference for you.

 

Yeah, 416 for a heads/cam car (even with a very small cam) seems quite low. Having the stock intake is surely holding you back quite a bit.

 

Not yet. The cam is being ground as we speak.

 

I will need to either port the stock manifold or install the fast, and then retune the car.

 

I have to tell you that after seeing my car on the dyno today, maybe it is not such a low number??

My car has headers, intake, tune and ud pulley. I pulled a 359 on the mustang dyno. My sheet and video are in my thread asking about cams. It will be insteresting to see what it is after the intake manifold and cam, but with the addition of the torque converter, it will read much lower than actual.

 

Low readings can also be the dyno itself.
