Re: G5X-2 cam & head Dyno Numbers You know I do Jason....when you coming back this way? I haven't heard from ya in a while. Hell I might even have my car running by the time ya get here <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />
Re: G5X-2 cam & head Dyno Numbers Sweet buddy! I hope to be back in March...it looks as though I'll be living in St. Louis soon. A transfer opportunity within IBM has come up and I am pursuing it. I need to get up there and see my sis anyhow--she is a freshman this year.

Re: G5X-2 cam & head Dyno Numbers I'd like to know more, like what's the compression ratio being run on this car? Stock rear end?
460rwhp is very feasable w/ ls6 heads/cam and a stock rear end and 11.5+:1 compression......
I'm sure my car, Justin's and many others would put out similar numbers with LS6 heads, high compression, and a stock rear end.

Re: G5X-2 cam & head Dyno Numbers how do you expect to make $$$$$ you could make tons of cash by selling the cam kit & head pkg
i like many are not going to drive 2k miles to have unknown parts put in my car
when i can do the install

Re: G5X-2 cam & head Dyno Numbers Verbs,
Are you saying that even with identical gearing (4.10's) that just the mere fact it's a 12 bolt vs. the stock 10 bolt it would change the HP output that much? I wouldn't think the differences would make that much of an impact on the final #'s.

The axles are thicker and heavier, and so is the posi unit/gears. More rotating mass= less power to the ground.
What I was getting at in general, is that a bunch of little things can add up and make for a good dyno run. LS6 heads, a high 11.5+ compression ratio, a stock 10 bolt, dynoing through an open y-pipe, etc. all add up and make for good dyno #'s.
Not knowing the full details of what mods the car has makes it hard to pass judgment as to whether this is the ultimate kick *** cam, or just a really good cam with a fairly optimal setup.

Re: G5X-2 cam & head Dyno Numbers I'm shopping for a cam.
I will not buy a cam without knowing the specs.
When Someone cam doctors it let me know.
Lou- if you would like to sponsor the first
'cam only' 10 second M6,let me know.
I could sell a few cams for you. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
e-mail-minushuman@iwon.com
I don't care about dyno #'s,I care about ET.
...but there is a direct link between the 2. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Unfortunately those cam specs don't tell us ****. The lobe profile, opening and closing points of the intake valve, lobe separation etc are all extremely important and not covered with those pair of cam spec numbers above...

Re: G5X-2 cam & head Dyno Numbers Why only one copy of this car? It is going to remain off the track for another 2 or so months.
Would you mind sharing the the calculated CR?
The dyno is impressive. Thanks for the graph.

Re: G5X-2 cam & head Dyno Numbers Congrats on the numbers they are stellar. My guess is that these runs were made with a huge cam 238/238 .59x/.59x 108 lsa cam, C/F driveshaft, alum flywheel, stock rear, 95 octane gas (still technically pump in Texas <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ), and skinnies on the rear inflated to 50 psi <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" /> There have been people that gained 10-20 rwhp alone on dyno tricks it doesn't seem to far away from others numbers that have posted here.

Re: G5X-2 cam & head Dyno Numbers Well I can atest that it was a GM steel driveshaft, stock clutch, and 93 octane, and if anything the tires (295/18s not spares) were at most 35psi but more likely 30 since he is driving it back today.
So the ASSumption thing still holds true <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: G5X-2 cam & head Dyno Numbers Will this cam work on a stock headed car? Would valve reliefs be needed? Single or double springs?
Is the cam too big for a stock compression car?
Thanks
Jason

Re: G5X-2 cam & head Dyno Numbers Ya' know I think it is funny. All the Cartek guys (on Corvetteforum, heck on all the sites) come out to bash on Lou as soon as he makes the announcement. They griped that the dyno was rigged to get those numbers, that their package was better since they did their numbers in a c5 (etc...).That since the test was done on a F-Body the post should be moved out of C5 tech....
Now, that was not Cartek themselves (Julio, etc..), just their customers. Anytime anyone posts a big number they are all over it. Now, brent's car has dyno around 450 with a 4.10 gear. So, he is figuring his car will dyno 463 or so with 3.42s. Yes, Cartek IIx pkgs have run 10's in a C5.
I have yet to see the EXACT cam specs of a Cartek IIx pkg. They have been notoriously secret about what they are doing. I don't see anyone complaining.
As far as I am concerened all those guys can keep their numbers secret. They did the R&D, not you. Now, I would hope at some point the numbers from Cartek and others would come out, so we can add that information to all the other that is out there.
My reason, I want to have all the information possible, and I want to make the most HP with the fatest curve.
But, LGM did the research, and invested the time. It is no secret that stuff Lou has developed has been copied on several occasions.
I don't see any of the CNC shops handing out their data files on their cylinders heads so you can duplicate it at any shop you wish...
All I can say to you cry babies is grow up... Learn to understand what competition, and running your own business is all about.
To Lou and the rest of the crew @ LGM. Props to you guys... I look forward to a test of your pkg in a Z06 with your headers to shut up some of the others out there...

Re: G5X-2 cam & head Dyno Numbers Lou,
If you wanna have Louis get ahold of me on the indycamaro.com site we can make arrangments to put his car on my dynojet and have another 460+ rwhp dyno graph to post.
