Want a cam....have some concerns...tuners help?

[BlownSS]

Okay.....i will preface this with my expectations of my car and how I use it.

It is a garage queen and I have no near-future plans of taking it to the drag strip. I do not do road course racing with it. I just like to take it out on some nice days and hear the motor and SMILE!!!! I am a huge fan of the sound of a semi-lumpy cam. I want it to be super reliable and easily driveable on readily available fuel.

So far I have the Maggie, Long tubes with high flow cats, MSD boost-a-pump, and Jannetty tune. It runs great now and when the weather is not too hot, it makes 546 rwhp. I do not want to exceed 600 rwhp.......

My concerns are:

1. Running low on fuel / leaning out in the high rpms due to not having a dual fuel pump.

2. the bottom end is not forged and I have no desire to spend the cash to do this if I dont need to.

3. starting something that i will be chasing problems forever.


I really want something that i can do to liven it up a little, get the lumpy sound and leave the car very reliable without the worries that im going to blow the thing up...I have heard that the ls3's will hold up to 650...some say 700.......just really confused......

Anybody have ideas what to do for a cam? General impressions for what i should do from here? Criticism? Dont pull any punches...i would rather have my feeling hurt and cry now rather than cry when my motor blows up!

I am kinda leaning toward the stage 2.5 Blower cam from ADM but wish it sounded a little bit lumpier!

I want a little "lump" but it needs to be wife friendly. I will be talking to ADM in the next week or so hopefully to decide....

ETMC Stg II Cam!!! Just installed one in my 06 112H LS2 GTO. The driveability is great. I havent had a chance to do WOT yet as i am waiting for a 100mm MAF sensor. But will have dyno results soon.

Tony on the safety side of things:
1: A blower cam helps reduce stress by evacuating boost. i.e. Lets say your at 9lbs of boost now, A decent blower cam might drop you down to 8 or 7lbs. The lower boost number doesnt mean you loose horsepower but show that your engine is now a more effiecent air pump.
2. As for a specific engine being good to a certain RWHP range is bogus! There are Stock Bottom End Ls1 with Heads, Blower Cam, Pullied TVS2300, E85, and Longtubes making 700+Rwhp. The reason is stated above ^^. Reducing Stress by making the engine a more effecient air pump!
If you need more info on the ETMC Stg II cam. Pm Me and i can get ya the info from Stephen at ETMC.


Here's a Soundclip:

Thanks for the input LJ, Any issues with fuel ? ......was just thinking about a cam and the rear cog drive setup on the maggie for now and calling it done at about 600-620 rwhp ........that should be good enough for the yearly poker run huh? the car sounds sick! Now get those tools off of your vette! It not a tool bench! LOL

I know that you already know this but you tempt fate with the mire stuff you do. I'm not saying that it will break but the chances dramatically increase as you increase the power. Im on my third rebuild and Ted does all my work so you know it's gd. Sometimes shot just happens.

yeah, the tools were off of there weeks ago!! This was the first start up so i was a little giddy to get it fired up. I havent had any issues with fuel. Just upgraded to the Siemens Deka 60lb inj. (Which was a PITA with the Maggie fuel rail on my 112 to say the least). But like I said i havent had a chance to do WOT test/tuning until i recieve a bigger MAF sensor.

I couldve went with the 2 bar Speed Density setup but didnt like the idea of it and would rather keep both MAF/MAP systems working together the way GM intended. If i was really pushing the car to be done i couldve raped the PE table after my stock 85mm MAF maxed out but really wanted to do things the right way.

superchargedss, when did you do 3 rebuilds? i know you messed up a lifter then put better pistons but that's only 2 times?

You make me petrified to even open my hood!!!!

[06x6spdGTO]

Alot of it is in the setup. Like the Stock Bottom End LS1 GTO I posted earlier. He has decreased boost as much as possible with a large set of ET Performance 265cc heads, Blower cam, and Longtubes. Making around 11lbs of boost. Then addressed the heat soak/detonation issue by running a cooler fuel charge (E85 in his case, Meth inj also works well). And hasnt went ape crazy on the timing/fueling to create a reliable Street Monster!! Personality and Driving style also play a huge role in making a power setup survive.

Heres a small write up on the car: http://www.ls1gto.com/forums/showthr...el+Chicken+TVS

It's not that bad! I just chalk up my problems to freaky occurrences. I had a stock lifter fail and then some gas so bad even meth and a gd tune couldn't save the number 1 piston. We have to pay to play. Just be careful and you'll be fine.

Look up the g6xb from LG Motorsports..

I keep landing on this cam, too...are there any sound clips posted anywhere?

Thanks for the link!

The ADM stage 2.5 has a little lump to it.

there is another guy that is on here that has about the same setup as i have now. I contacted him and am trying to figure out exactly what he did and whether it has been reliable for him. Like I said, my biggest concerns are lack of fuel and the bottom end. I am running the 3.6 pulley now ....i changed it when i went to the long tube headers....am I correct in assuming that i can go back to a 3.8 pullley since i wont need as much boost?......still confused!!

[Kilo-9]

Do you mean after the cam? Installing a cam should lower the boost because of the increased overlap.

Or, are you saying that the engine will make more power with the cam and will require less boost to stay at the same or similar power level as what you currently have?

[1bacamaro]

here is a video of my car on the dyno after cam install. the car has a tvs2300, kooks headers, flowmaster axle back and airaid intake, BOP.. car did 608rwhp on a mustang dyno. great power and my wife drives it everyday.

Yeah, I am saying that it will require less boost for more power.......Like LJ said above. it will become more efficient and wont need as much boost,.....I think!


This one is also highly recommended amongst most of the high end tuners!

i am running a 3.4 pulley and run 9lbs of boost. TRUST ME you will be happy with this setup. i can put the car in 6th gear at 50 to 55 with no bucking at all. i have yet been able to get the car to buck.

Ok, I understand now. I was thinking that you would want to maintain the same amount of boost you have now, which would require a smaller pulley. You aren't necessarily looking for "max effort." I'm think I would add the cam and keep the 3.6 pulley. You'll be making more power, yet the effective boost will drop from where you are now with the addition of overlap.

[1bacamaro]

same injectors that came with the maggie and yes i run a boost a pump. not sure about cam install because i did mine myself.
