I dont see this as a pot shot, seemed like a reasonable question to me. I was thinking the same thing

I am not Hubie 
but there is more in store. We did some cam testing and will post info shortly. Its pretty good stuff! We have a few more things we will do with Mary before we are done.

I like how FTR did this, before and after results with soley the head changed. Anybody can figure it out.
I assume that plenty of drag strip testing will be performed before the October NHRA event. Should be a blast, 9's perhaps?
Great job!

CAMSHAFT TESTING
Decision in camshaft design is influenced by numerous factors. Compression, displacement, usable rpm, cylinder head flow, driveability, and reliability all factor into the equation. Profile and geometry come into play as the lifters ramp and un-ramp quickly and valves are reseated as gently as possible. We have designed and tested countless variations and finding that perfect balance has been a never ending process. Project "M" will ultimately transition into our race program, so we limited our cam testing to very specific grinds since none of the stock exhaust or supercharger components will ultimately factor into the final power equation.
We decided on two profiles, CAM A and CAM B, to be tested in Project "M". This decision was based on the current configuration and our goals for Stage One of the project which is maximizing the output and efficiency of the M45. CAM A is on the aggressive side and the results of our testing was disappointing, but not unexpected. The factory hydraulic lifters were unable to cope with the aggressive profile and collapsed on the first pull.
The noise from the valve lash as well as the ugly dyno graph verified the problem as power fell off immediately as rpms increased.
Fortunately, there is always a plan B and we had our CAM B ready and waiting. A quick swap and return to the dyno resulted in exactly what we had expected. Unfortunately, our expectations of CAM A were quite high so it somewhat dampened our enthusiasm for the gains achieved with CAM B.
Increase in HP from CAM B:
Graph of DATA:
Overall, the cam shifted the powerband upwards with an increase in WHP from 8-13, depending on comparisons at different rpm points. Peak torque and low end WHP dropped due to a few factors, but mainly because of change in cam profile towards our needs at higher rpms. Peak boost fell slightly, as expected, but we are excited with the results considering no other changes were made and we look forward to our scheduled pulley change.

maybe someone's already suggested it as its so obvious - how about Project Madonna - keeps the smack on other vendor's intact, doesn't step on toes (may still be uncomfortably close to Mary), although it does have an unfortunate reference to certain pop star... hmmm, project virgin? That won't be confused with that pop star..

I have seen this before during cam testing RMW's did on my car.
You can see that it picked up power at the top (starting at 6500) but killed the TQ down low. It looks like a loss of 10lbs of TQ until 4200. You don't gain any of the TQ back until 6500.
I know what this is like and drive-ability suffers greatly. With the loss of TQ the time it takes to get to 6500 is now allot slower.
Why did you increase the RPM's again?

Besides, I am only hesitant in sharing the super "ridiculous" top secret data until we are ready to let the world know how much power we are really making.......

******NEWSFLASH******
Today we broke new ground!! With a couple small changes and a few tweaks to the black turbo car we 513WHP , yes that is correct five hundred thirteen WHEEL HORSE POWER!!
Charts and video to follow.

How do you drive a front wheel car with that much HP? Very carefully
