Effect of higher stall on dyno numbers? I'm set to pick my car up today from my tuner. It's finished I just haven't seen the sheet on it yet. I know this car isn't going to wow anybody with it's dyno numbers but it should run pretty strong at the track for what it is.
All I changed that should effect the dyno numbers is the cam, lid, and converter. Previously it had a 224 r cam and a yank ss3600 converter. It made 409 on the same dyno, same tuner. Now it has a super yank 4600 with a btr stage 3. I'm thinking that if it still puts down 409 I'm lucky. I'm not so concerned about the dyno numbers unless they are way low and indicate a mechanical issue. How much would the converter swap hold it back on the dyno?

Depends on the percentage of slip the old one had and the new one. If it made 409 through an auto with a 224r cam you can bet it was locked (and still a happy dyno).
Assuming the tuner locks the new converter as well there should be little to no difference in the converter. That said the dyno is a tool and it's only as good as its calibration and input data. It could vary day to day even with no changes to the car.

It was locked. I was able to be there in the shop that day while he did it. He actually let me make the pulls while he watched the data. We'll see what the sheet says I guess. I'm planning to hit the track on Saturday, I just want to be sure everything is working as well as it can be.
Truth be told the old setup went as fast as 11.38 @ 119 in good weather but on your typical day it'd run about 11.6-11.7 range. Hoping this thing will run low 11s if not run 10.9 in great weather.

It ended up making 380 at 6000 with the converter unlocked. He said it'll probably pull to 6500 but he just never pushes street cars that hard on the dyno. We'll see what it does Saturday at the track
