Would like to run 11's- 6 speed, full weight, 3.42's
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".

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.

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

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.
