Default SI5 cam only guesses?

Well I will be getting a cam swap done on my 2000 M6 SS soon and was wondering if anyone has any guesses on what it will put down? The car already put down 358rwhp and 366rwtq with boltons.

My supporting mods are:
Lid
Fast/NW 92/90
U/D pulley
LTs with an ORY and Magnaflow exhaust
built trans. with LS7 clutch
9" with 3.89s

Yeah, with the help of your bro Larry and watching your Dad's car at Byron is why I decided to go with the SI5. Both your brother and your dad are very helpful and great people to talk to. Speed Inc. will actually be doing the install. You own the SOM Malibu right. Your car is wicked!!!

What's the specs on an SI5?

I made 412 with mostly the same mods, with the cam in my sig. That's on a CTS-V with rubberized crap throughout the drivetrain (making it closer to 20% loss), and stock 3.73 IRS.

Depending on the cam's size, I'd bet you'd make about what I do, assuming you have stock 241's.

When are you installing & dyno'ing?

Nice choice on the cam! I'll guess 396 hp.

My a4 SS put down 420/388 with it, LS6 intake & TEA 5.3s.

had a customer of mine in australia get back to me with some cam only SI5 results.

I thought dyno dynamics were the "heartbreaker" dyno? From their conservative results.
