mild cam w/stock stall doable?
http://www.ls1gto.com/forums/showthr...819#post477819
is this really doable...I'd like to put a TR224 in and run w/no stall for a few months if it's doable.

Pretty choppy and lopey down there.
Driveablity...The car drives very well for the cam size with no stall. Rolling up to a stop it finds its idle ok, but with tuning that will come easily... At the stop light you can let it idle, but its very choppy which is to expected, but not bad IMO. Driving can't even tell the cam is there. It pulls away from a stop very easily and is very easy to drive. Little to no surge, only experienced it one time and never again. Haven't had a chance to really swing it up through the rev range yet, wanting to get the 921's broken in good....
Overall, I would say its not bad at all, for a 228, 112 cam with no tuning in an A4. It should be tuned in about 2 weeks when he gets a new version of Tuner Cat OBD2. Also I just closed a deal on a PI VIG 3600. So I will report back with findings of those changes to the car....

Right now I'm running the gmpp ASA cam (226/236, .525/.525 110 lsa) with the stock stall converter. I'll tell you this.....it's not ANYWHERE near as bad as everybody here says. Running on the stock '98 tune it ran absolutely fine, but it would try to stall out when coming to a stop so I had to "two foot it" a little. I drove it for a month on the stock tune. Now that I've tuned it with HPT, I've got it idling at 700rpm in gear and it runs freaking awesome....hasn't even come close to stalling out. I can be in gear at a stop light with the a/c on high and both radiator fans running with no problem at all---and it hits sooooo hard .
Now even with a 700rpm idle, you will be pushing harder on the brakes while stopped in gear--but it's just barely more pressure than stock.
With that said, you will want to put a converter in eventually. A 3000 (or higher) stall will wake that cam up big time. With the stock stall, my car is nowhere near a dog in the lower rpms....I actually don't think it's that far from stock. However I know my car would be a ton faster with a big converter. The only reason I haven't done it is I think I'm swapping to t56 pretty soon. Enough rambling....my advice--freaking do it!

Since I've tuned the car, it has not come close to stalling. I drive the car every day and the only thing I've noticed is there is a TINY TINY bit of surging at about 1600rpm under light load. My wife can't tell, but I'm extremely **** so I can feel it. I'm still fine tuning the car so it's easily fixable.

It's so much easier to have it run right after a stall then to be surging and stalling with the stock converter in there.

I like to drag race, but in Austin, no one ever does...it's all about roll racing here apparently
so I'm seeing which will help me the most, the stall or cam, so I wanna do the cam if possible

Believe me when I tell you, these fellas that are telling you they are "just fine" with 224 and larger cams in their stock converter cars are trying to convince themselves more than they are you that their mismatched setups are ok.
If you want to do things properly, get what you're paying for with the bigger cam, and not get pushed down the highway when you try to brake, do it right and put a higher stall torque converter in your car. Besides all that, between the two, you'll get more for your money performance-wise with a converter swap than any cam you'd put in your car, especially when that cam's potential is hobbled by the stock converter. Name one cam that you can shave .4-.5 seconds off your 1/4 mile ET with. If you can, you should run right out and buy it, but the fact is, you can't. That same .4-.5 second reduction can happen with any decent-sized converter and for that reason alone the best choice should be obvious.

Get a converter first. What's with people nowadays wanting to do things all backwards? Do some reading/searching and once you have actually learned more about these cars and the mods that work for them you will realize the importance of modding in the correct order/way. That being said I had a A4 with a stall in my last WS6, so I'm not just some M6er spewing off at the mouth.
Two choices here: listen to the veterans and get a converter, then go out and WAX these guys that have a stock stalled cam only car, or join there club and PRAY you don't meet up with someone that does it right!!
