US stall converters
The car in its current state is a VY commodore LS1 4l60e with PAC 1218s, 3.91 diff, full exhaust, OTR and a tune, runs 13.1 @ 108mph with a 2.2 60'.
Currently looking at a comp cam 228º/232º .588/.595 112+2, now im thinking of a stall around 4200-4500. Now i was looking at a Circle D 5c, which was going to cost me 1000 USD to my door, but the guys im buying my others bits from sells the vigilante converters, which i have'nt heard to much about, but going that option is saving me about 300usd.
The car will only ever get used every 3rd week due to working away, its going to be used for street/track.
So what do you guys reakon?
Now Yank is slipping in customer service and "supposedly" machining.
So Circle D is the big dawg now. I personally just purchased the 5C 4000-4200 Converter from Circle D. It shipped today

Certain parts are your "core" and should not be cheaped out. I Personally believe the Converter, the heads/cam and the rear should not be overlooked and went with what was cheap.
The Precision Industries Vigilante Converter you hardly ever hear anything about them anymore. And when THAT happens, there is USUALLY a reason. Just stay away from Vig'
There are a few companies over here selling circle D, but their prices, looking at an extra 400, so yeah, ill buy from the US thanks.
So a 5c will match well with that cam and gears?

OP, Vigilante has a solid reputation, as does Yank. And Circle D does as well from what I've heard. I think all 3 of these companies make a solid product. I will say that a 4200-4500 converter may be a bit much for that cam. I have a very similar cam with a 4k and its about as perfect as you can get for a street/strip combo. I honestly don't think there would be much to gain by going up in stall speed much above about 4k.

When thinking 4k+ stalls think high 23x or 24x duration cams. There is no sense in stalling the engine up PAST a cams power band or even too far into it to start. A 228 is a low speed torque cam that builds from 3k-6k. If you want to jump in to the 4s or even mid 4s in the revs then do it with a cam that builds FROM 4k-7k+.
So if you can wait a bit you can order from your local dealer

Find me the small cams in the stock bottom end record lists.
Nobody said it wouldnt work. It will just work better with an appropriate cam. Nobody said anything about driveability wants or anything else, so its assumed, that all that matters here is 1/4 performance. Especially considering OPs mods like 3.91 gears in an A4.
