I am realllllly putting hard thought into either a ls6 cam, or a b1..

i am mostly looking for driveablity, and i want to pick up 25-40hp as well.. i know i could go with a 227/224 570+ on a 114.. and pick up alot more, or even go with the f1 cam or g5x2 and get 400+hp.. but thats not what i am looking for.

i drive an automatic, and its a daily driven car at that.. i dont have time or money to put into this car fixing it all the time, or trying to keep it tuned, or trying to get it started on a hot day, or trying to get the bitch to idle correctly. i want something i can put in, tune once, and never mess with it again till i add more mods.

but that brings me to my questions..

i know the ls6 cam will enable me to pick up 30hp or so on a mostly stock motor.. but i have heard adding things like longtube headers ect dont respond well with the cam, i heard someone with a z06 cam put longtubes on and only picked up 5hp.. i also read that it was because the ls6 cam is designed to respond well to a restrictive exhaust, and adding a free flowing system wont help much.

i am waiting to see what kind of intake manifolds are going to hit the market in the next 6 months before i take the plunge, so ill stay with my ls1 intake for now.

i want to acheive good low end, while dynoing in the ballpark of 385hp on the top end around 6400rpm..

my mods will be,

K&N FIPK
Maf Ends
Ported TB
QTP race style 1 3/4" headers (not sure about the collectors yet)
True Duals (not sure about h or x pipe yet) thru bullets, dumping before the axle.
3.73 gears, zexel torsion diff.
!egr, !air, TB bypass, LS1 Edit.

do you guys think ill acheive the numbers i want?

around 385hp up top, with a nice gain across the entire rpm range. or will i keep stock power till 5500rpm then get a little more top end.. maybe even losing some low end.

if the cam wont perform well over the entire curve, giving me more torque and hp across the board, and if it wont respond to a better flowing intake and exhaust.. then im going to pass on the cam. but if it will respond the way i would like it to, the price cannot be beat.. i can get the entire setup for under 400 dollars shipped. its hard to find an aftermarket cam for that price alone!

I'm a guy who likes to go pretty conservative on cams. I really value low-end torque and driveability. As I am running neither of the cams you are currently considering, I believe I can be fairly unbiased. You can see my "old man" M6 setup in the sig below. With my pulley I am probably making around 385 rwhp now. Note I have ported heads but no LT's. My cam on a 114 LSA might be a good choice for you.

I have to agree with chikn that 385 with the LS6 cam is going to be tough without heads, especially on an A4. I think 365-370 might be more realistic.

That being said the '02 LS6 cam is a good performer for the money. It offers excellent idle characteristics and good off-idle performance due to the low intake duration. Good lift and a wide LSA extend the powerband nicely for a good increase over stock in top end HP.

Nonetheless it will not give you as big a boost in HP as a cam with more duration, and will not provide as much midrange torque and "area under the curve" as a bumpstick with tighter lobe separation. The LS6 cam is more of a compromise toward stock-like driveability.

Given your HP goal and the fact that you have LS1 Edit (you will only have to tune once), I would probably think about going a little bigger on your cam. Obviously you will want to raise your idle and rev limiter as well as adjust your a/f. With 3.73's you should be able to get away with using a B1 and still have decent low-end punch. A bigger stall 'verter might have been an even better choice than the gears IMHO. Some newer cams such as the TR220 have more aggressive ramps and will idle better than the tried-and-true MTI/Lunati grinds at roughly the same .050" durations.

Good luck with your choice. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

you won't get near 385 rw with a z06 cam...

to get that your gonna have to go big...your concerns about engine life will have to take a back seat...you have to make a tradeoff

if you want 385 rw you better go with an x1, f1, or a big xer lobe comp cam...

your going to have to get a 230 intake duration to aid your ls1 intake. if that is what you want then just don't plan on getting a z06 cam to get there...

i tell you this stuff its like talking to a brick wall

There are guys on here that have made what you're looking for w/ a TR220. The B1 will probably give a little more peak hp, but will give up some lowend power/drivability because of its higher valve overlap. Advertised duration has a bigger impact on where power/how much power is made than duration at .050". The B1 is 280* and the TR220 is 270*, but both have comperable .050" numbers.
As for the LS6 cam...sounds like it puts down decent numbers, but I've yet to see anyone run good times w/ it at the track. Also, it doesnt add any power until 4000 rpms. Just look at some of the graphs on here. Another thing that I've personally noticed-you'll always be looking for more cam. I'm on my second one and could tolerate larger.

I agree with the comments about the TR220. In my opinion, that would be a better cam for what you're looking for. A 112LSA will help shift the peak power a little lower, which helps low end torque, but on an A4, it will hurt ride quality. This can be overcome with PCM tuning, but I don't know if you planned on doing that.

As others have said, you will not get anywhere near 385RWHP in an A4 with the LS1 intake and stock heads and stock manifolds....350-360 is the most I would guess.

How about LPE's GT2-3? Similar specs to the LS6 but with more lift <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . Same or better idle too! There are few guys I know with out heads using a similar exhaust set up making 380rwhp with some tuning. Great street cam with good power.

i think im just gonna go with a TR224 or something similar.

i hope i can find a good deal on it. all of this hype about the ls6 cam makes me want to run out and buy it right now.. but when you look at dynographs it makes me want to scratch my head..

i wish some halfway descent intake manifolds were available on the market besides the ls6 intake. i had my order form filled out 2 days ago, and was about to hit submit, but forgot that i might need the coolant pipe kit, so i came here to search for it and found another thread talking about new intakes on the market soon, so now i have decided to wait on that.

oh well, at least there are good headers out.

just wondering, but for those who want just a bit more cam than an LS6 but still want a stock like idle, how about that new comp cam: 212/218-.56x" on a 115lsa... should be smooth with the 115, make decent mid range power up to 6000 with that duration/lift and lsa and should run with stock programming and idle, no??

Chikn makes a very good point with the cost issue. I`ve been looking into cams myself and the LS6 seems to be putting up good #`s for most at a fraction of the price of a aftermarket cam/springs set up. I think the LS6 coupled with a set of Stage 1.5 heads would make for a tough street set-up. Sneaky too. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

you can get any comp grind, 918's, and hardened pushrods for $589 total

My LS6 cam swap cost me a tad over $300 and I have been very impressed so far with the gain. I am planning on a set of QTP LT's combined with a set of Stage 1 LS1 heads and a set of nitto's on the rear. I'm thinking this should be a very quick street car that sounds and drives stock. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
