I would like to get into the 11's with stock gears, cam only with bolt ons. Not sure if it can be done full weight or not. I'd run on DR's. I'd like to know if there is a cam or several cams that can lay claim to this. A good friend has an 01 Z hardtop no power options with the Trex, bolt ons, no weight reduction, 3.42's and ran a 7.80 @ 95 on ET streets with a crazy launch once. I see cams all over the place on lift and duration and most seem to make low 400's to the rear with the LS6 intake, so I'm wondering if there really is a big difference between the 22x/22x 560-580 cams vs 23x/24x 590-610 cams. I ran 12.05 @119 with a weak launch and 4.10's with the 224/228 581 112 XER, so I don't think it will get it done with 3.42 gears. Thanks for any help as I know cam threads are quite old and annoying, but I have a specific goal in mind until I get the money for a 9".

You can do it pretty easily, just get any decent sized 224 or up cam and set the suspension up right and you'll be in. you'll need drag radials though

Yea, I'll run DR's. I never touched the suspension on my last car except to install Hyperco springs. I also do not want a drag only type set up, like 50/50 90/10's. I'd do lca's, relo brackets, etc. My overall goal would be 10's with a 9" and 4.30's.

Goodluck going 10's with CAM only and no weight reduction.

I'll do some weight reduction, probably from front end suspension parts. Whenever I get the money for a 9", the other mods will be lightening up where I can without detracting from the car's safety or street driving. Like I said, my ultimate goal will be 10's, but for quite some time, I'll be working on getting to 11's.

LCAs, DRs, Panhard rod, tunnel mounted Torque Arm, the hardest thing will be learning to slip the clutch right so you don't hit the tires too hard, and not bog the motor down off the line. And if that doesn't work, just spray it.

I would gladly give up 10 peak hp for a cam that's super strong all the way up as that's where it's at for me. I just reread my dyno sheet from 2.5 years ago and my 224/228 made 373 rwtq, so I'm sure there's plenty to be gained there with a newer cam.

You'll defintely have to get a custom grind cam to get "alot" better rwtq numbers compared to what you have.

Talk to Predator-Z or PatrickG about a cam, they'd know best.

If the traction is there you can do it with right at or less that a 230 duration. Its all about the combination, and if you get everything working in harmony I dont see this being a problem.

The PatG cam was 230 with slightly higher lift and a lower LSA than my old 224/228 cam. Deciding on a cam is a pain now that there are so many that make good numbers. I know he knows what he's doing, just haven't seen too many numbers from his cams. I know his cam physics and descriptions should work on paper, but would like to see some proof.

This is on a A4 with stall (cam only) + bolt ons

Redlinez

A4's and 6 speeds just can't be in the same discussion IMHO. I'll probably just go with the PatG cam. 230's duratation 590-610 lift and 110-112 lsa will all yield about the same results I guess.

PREDATOR-Z

That is a pretty presemptuous comment and ironic. That is why 90+% of top track dogs are Autos, yeah I see what you mean.

statement was probably made because auto's have a way bigger advantage on drag strips and launches, thats all. Nice numbers at the strip are def. harder to achieve and maintain at the strip, but im sure we all know that already...

PREDATOR-Z

With regard to cam specs:

>Autos will be harder to tune on high overlap Vs M6
>Autos like more advance in cam like +4 instead of +2 for M6 (Autos don't like to rev too high) at least on A4s
>The rest on durations and lift are compatible between both because being a pump the motor can only ingest soo much air once optimised for said cubes and other mods.

And what I meant ^. Autos have much more torque multiplication and already get out much, much better. Not to mention, there are LS1 series that have A4 classes and M6 classes. I mean, with a converter and bolt ons you guys can run 11's easily.
