I'm trying to pick a good cam for my A4 w/ stock torque converter/3.23s.

Unless you know me, please don't lecture me on buying a torque converter or gears, this is my 7th LS1 car. =)

Thanks!

good call...hahaha

hmmm, my .02 would be to find a cam that makes really good low end tq and gets up to the max at the lowest possible rpm. reason being is that your gonna wann keep that cam were its making power with your stock converter or gears....since you will be stalling at a low rpm you want your cam to make power quicker then most....now im not a super tech guy so i cant throw out numbers your way but you might get some better responses in the advance tech forum or the internal engine section....sounds like someone is making a completely streetable stock monster dont worry i wont tell your secret....oh ya and one last thing after finding some numbers that you want you might consider talking with a sponsor about custom grinding you a cam directly for your specific needs, such as timing in the cam for the bottle or maybe slightly diff lsa or more intake and exhaust overlap...idk im jus talking off the top of my head but those are things to think of.

FWIW

It's less of a "stock" setup, more of an extreme budget / lazy configuration. I don't mind throwing in a cam, but I've swapped enough torque converters in and out to last a lifetime. I hate connecting those damn cooler line clips! =)

C. Lobe Separation Angle (LSA)


- LSA is defined as spread in camshaft degrees between the intake centerline and the exhaust centerline.

- Overlap is the number of crankshaft degrees that both the intake and exhaust valves are open as the cylinder transitions through the end of the exhaust stroke and into the intake stroke

- LSA is ground into the cam and cannot be changed without grinding a new cam

- Bigger duration cams will have more overlap then a smaller duration cam even if both are on the same LSA.

- The key to making overlap work is maximizing the power in the rpm band where you want it.

- Long overlap periods work best for high-rpm power. For the street, a long overlap period combined with long-duration profiles combine to kill low-speed torque

- Reducing overlap on a long-duration cam will often increase midrange torque at the expense of peak power, but if the average torque improves, that’s probably a change worth making.

those are a couple sections just concerning the lsa of your cam choice from the CAM GUIDE STICKY in the internal engine forum!!!!

hope thta helps a lil bit

Maybe one of the CheaTR cams? They look like they might work well with a stock converter. I know my MTI R1 wouldn't even break the tires loose with a stock stall and 3.23's, and would only 2.0 60 ft. MTI also has some stealth cams that look like they might work well with a stock stall.

Hi Terry

OK.. I won't lecture. But, I would still do a converter before a cam

A wet nitrous kit I bet would help it get moving with a stock stall.

Hi Terry

Are you planning to keep the 3.23s?

You would get double the gain with a torque converter swap for less money you know

Terry Burger

Yeah, keeping those 3.23s. I figure a TC would give me a nice gain, but I hate removing those cooler line clips.

I'm leaning towards the GT2-3, LS6 springs, and an UD pulley, provided I can find someone who did those mods and picked up around .4ths. =)

i can only say from what i've had. i ran my MSv3 with the stock stall (already had 3.73's) for about 3-4 months. it worked pretty well, i beat an 04' cobra with dr's when i was on kumho's by about 1/2-1 length. i never took it to the track without the stall so i don't know what it gained but driving was fun

the cooler line clips aren't bad :dunno: i pulled that heavy *** th400 out today, a straight slot pocket screwdriver is your friend

i would suggest a TR224 on a 112 or something similar....

Cut the tranny lines by the starter and put quick disonnects on the lines. Makes life 10x easier

Man, now you guys have me thinking of installing a Vig 2800 converter. If I do that I'll just go with a 229 cam, and I guess I might as well take some weight off... All I need, another huge project.... =)

whats huge about that project?

i think it needs a MMS 229 cam, yank 4400 converter, and a wood hatch!

;-)

Terry Burger

Haha its funny people still rib me about that hatch out here, hey, it saved like 60 pounds! =)

So, what is the best cam for torque from say 2000-4000rpm?
