That's good to hear. So how did you get the ls9 crank pulley to fit the crank? I'm trying to run this system on an LS2 with wet sump and stock crankshaft. Are you running an LS6, LS3, or Ls9 oil pump? Any info is greatly appreciated. Thanks, Lyle

We did the measurements for a hub and balancer to line up with the LS9 accessories using an LS1 type crank, and had ATI build it for us.
Turned out perfect!
I'm just running a ported LS1 oil pump.

Assuming that you would control it with a reprogrammed stock ECM, I think you would just need and extension/adapter or two; nothing special.
Just treat it as adding any kind of roots SC.

Finally got a chance to get the car back on the dyno with the smaller supercharger pulley.
It made 610hp (up from 564 with the bigger pulley) so I'm happy!
Here's a couple vids on the dyno:

And a plot of one of the runs:
Now it's back to the track (when I get a chance) and see how it does!
The car is running good!

Have not addressed that yet Ian. I'm still running the TCI box on the trans while we work out some other R&D stuff.
Then I'll switch back to the T42 and log some launch data. I didn't even know some of the parameters were available for logging "TM Type" back then or I would have captured the data then, and might have had that issue fixed by now.

Took the car back to Muncie Dragway on Friday for RPM Transmissions Track Day.
I made some more adjustments to the Moser torque arm to try and eliminate blowing out the tires on the launch.
Good weather, good track, GREAT EVENT!
The car went 10.07, 9.87, and 9.94!
The car is running great and everything is working well together, so I'll keep tweaking it here and there and make as many trips to Muncie as I have time for as the cooler weather gets here!

I'll keep tweaking away, I'm sure there's more to be had! I want to play with a better IC reservoir to keep the water colder.
No cage yet Ian! It's no problem at Muncie, but if I don't put one in, there aren't many tracks that will let me run; at least not more than ONE pass!
I think it may hit 140mph when cool weather gets here. We'll see.
The biggest mistake I made on the whole car was waiting too long to put some good headers on it. I was trying to be the patron saint of stock manifolds or something, thinking they would do almost as good as headers.

9.79, 9.71, 9.75 sec. videos added! Took the car back to Muncie a couple of weeks ago.
Adjusted the tune a little for the 100 octane unleaded gas.
Car is running great!
Here are the videos of the three runs I made (in 1080p HD for your viewing pleasure).
