Stall question for ysi?

2012 ss, forged internals stock stroke
Vortec ysi 23~ psi
Meth
93 octane
4l80e.

My question is what do you guys run for converters. Iv never been around a supercharged setup so this is my first.
I know turbos you'll run a smaller stall to get it to boost easier.
But do I need to run a bigger one since vortech is belt driven and to keep my cam up in power band?
I know it's a broad question but insight would be helpul!

Yes. A centri with big stall is a common combo. IMO the best one for drag. I think Scotty had a 3600. I am not yet at the stall part of my build and am still undecided.

I got a big stall on my 6L80. Launches way better than my 26-2800. Unfortunately I'm having shifting issues at the track. Daily driving its perfect. On part throttle RPMs stay up. I plan on going 4L80 and also plan on a 3600+ stall. I say the bigger the better but tuners keep telling me 3500 is good for drivability. I don't care for drivability but for some reason they do.

If your talking about ScottyWheels he had a protorque 3600. I got to talk to him a few times when I was researching for my YSi and he said he would have liked a bigger stall. 4000+. That's when I decided to get a big stall and get what I wanted not what they offered.

I have a 3500 in my 6l80 right now and truthfully wished it was bigger lol.
But I keep hearing big as you wanna drive. Ill find the video I watched today of a 4l80e swapped 5 th gen with a 5200!!

Exactly! I didn't plan on running less than a 4000 if I go 4L80. A big stall makes my setup feel like its suppose to. Tuners have actually told me its harder to tune. Maybe that's a good reason why we don't see too many high stalls

Im leaning towards either a 4200 or 4400

Do you feel like your getting all you can out or better driveability with the smaller stall? I'm not talking hp numbers I'm meaning times etc.
