ZZP Stage 2 cams. dyno proven difference.
Ok folks, I just got back from ZZP with a dyno difference between stage 2 cams and stock cams.
Background:
ZZP CAI
ZZP LT header and 2.5 catback
80's
ZZP E85 dyno tuned 360 whp 284 wtq
ZZP Stage 2 cams
Ported head
ARP headstuds
Supertech valve springs
Cometic head gasket
TVS with 2.7 pulley
RSFS
ZZP fuel pump
Dual Pass
Option B
Griffin
GMPP clutch
Wideband
Rotated Trans mounts
Fuel Pump Rewire
Here is the skinny. Ill include the dyno sheet. I dont have a scanner so I took the best pictures I can. The dyno sheet has both the old dyno and the new one. Keep in mind the enviromental conditions were different. it was much hotter (~85-90 degrees farenheit) on the day the stage 2 cams dyno was done. The sheet shows clearly that boost has dropped by an average of 3 psi throughout. Also the torque is higher throughout the entire power band. (some people had said it would be lower) Horsepower is higher throughout but the gap is higher at higher rpms.
The dyno sheet goes to 7500 rpms. for some reason the orginal pull would only show up to about 7000 so it doesnt show it going to 349whp but it did.

Nice man!!
I felt a nice bump from my S1 cams. It's good to see what the S2 cams can provide.
Sadly, I would not have an accurate dyno to compare like you, because my car wasnt dyno'd recently on the current setup before the cams. I am going to have her dyno'd in the fall though just to see where I stand now.
Make sure to add this to the dyno thread. I've been meaning to update it for everyone. I've just been very busy at work.

Although keep in mind my dynos were 3 months apart. and it was a lot hotter for the second one.

haha. so call me stupid but i'm having a hard time reading what the actual numbers are... it looks nice on the graph, like you gained around 30 hp but i cant follow the numbers you posted i got it confused. so your numbers were 360/284 before what are they now?

Oh well, this should end all of the assumptions (which is a good thing). Again, good stuff & nice numbers man.

The timing was only 24 degrees at 7500rpm, pretty conservative considering its running E85. Plus he didn't mention that I had to beat on his IC pump every pull, so the IAT2 temps were pretty high. When the IC pump is replaced the timing will be a couple degrees higher. 
With how it wants to rev it really could use an ATI balancer as well, but Nolan rarely revs it out so he should be ok for now.
The dynos correction factor isnt really fair to SC cars either on the super hot days, so I would love to redyno it on a 60 degree day.

Heat soak isnt the term I was looking for.. not sure why I typed that. I meant the intake air temp was 30 degrees higher to start so it wasnt as cool and I guess it was humid that day Tim said. But regardless I am not hung up on the numbers, It made good gains and is fun to drive. I know I need to get HPT but I dont know how to tune. but its on the short list of next things for the car.
