supercharger torque converter what would be a good stall size for a supercharger? street/strip. i heard that a 3000 stall would be good because the supercharger will raise the stall.anyone think thats too small? should i go bigger?
I have a Y3000 stall with my procharger setup and I have no complaints. If I were to do it again I would go with a 3500 stall. Does not matter anymore really as I am switching over to an M6 soon. 
I have a 3600 stall. As soon as I step on the gas it flashes straight to 5000 rpm, then half a second later I am at the rev limiter (very frustrating). I am currently in the process of changing the cam, so that I can extend the redline to 6800 rpms and get into the meaty part of the rpms. My 3200 performed pretty good on the street but was not enough for me and it sucked at the track. Something to consider.

you have an inefficient converter if its doing that. get one with a multiclutch disc and it should hold. Whichever you choose go with a multidisc clutch so it will hold. TCI, Fuddle, Yank are a few, just search around and see who can give you the best price.

I run a Yank SS3200 in my car & it's fine for street driving, and flashes to ~4k when I nail it. Shift extension is about keeps it up around 4500. Ask the Yank people & they will steer you in the right direction. All the torque from an FI motor will push the converter, so lower is better IMO.

Stall depends heavily on hp produced. My Vigilante "0" pump 2800 flashes to 5400 at 20 psi boost. Since the hp peak is at 5800, I'm shopping for a new converter. Back when I was running 13 psi from a Vortech, the flash was only 4000 rpm.
Mine is 4500 or higher, I forget. I was cutting 1.3's and trapping almost 145mph.
When you look at converters, keep in mind the higher it flashes, the harder it will hit off the line. But if it's too loose for your combo, you will be out of your powerband too fast during a pass.
Also keep in mind, when you run too tight of a converter, you will not have as much shift extension. That means, let's say you shift at 7000, and you have a tight converter. The revs could drop down to 4000 which might not be optimal for a track car being shifted at 7000. In fact, on shifts with a combo like that you might want the revs to just drop down to 5000, maybe 5500.
kp's car has a 8" converter, I'm sure he has nice shift extension in that car.

I went through a Y3000 and a TCI SF before switching to a converter that held up to the blower setup. I now have a custom built Continental converter - I'm overjoyed with it and it's holding the power great - but they're not a sponsor here. PM me or Google.

I ran a Yank and now a TCT, prolly should not have switched. If anyone was interested in my TCT, holla, should be great for a 8.9-9.9 car running big boost. Heck I might run the car again before it gets torn down.

It was out of warranty so I had Yank rebuild it and then I sold it. Not sure if the power was what caused the failure but since I was replacing it I went with a little higher stall and a more sturdy build. I'm sure Yank has something that would have worked but I went with Continental as they're local and build converters for many ProStock cars - supposed to be good to 1000rwhp and I believe it - they also came highly recommended by Rob@Strictly who does the work on my car that I don't do personally.

It's tricky to find a converter that works with big power. Fastest I went with my Yank was 10.3@136 but I had belt problems. Fastest with my TCT is 9.4 and 144mph. 5.999 1/8th @ 116mph.
