Cam + Headers + E85 results Finally got my missing exhaust pieces and got the car on the dyno. These numbers are with a stock air box and filter, plus the added forged pistons result in a little heavier rotating assembly. Car is an automatic.
I did not opt for a CAI because I will be adding an ECS kit very soon.
Here is the graph breakdown:
Baseline --- 391/414
Cam + Headers (no cats) + pump gas --- 432/424
Cam + Headers (no cats) + E85 --- 458/442
Cam + Headers (no cats) + E85 + stock air box opened without filter --- 471/450 (5th gear pull, not 1:1, probably another 20hp or so in 6th with the A8)
There were lots of changes made to the car and it sits at 4,000 miles now on the odometer. Most of the changes were to make things stronger for forced induction such as trunions, pistons, LT4 injectors and pump. So most of the expense did not yield any change in power this round. Most were made preparing for the next round

Nice work man. I should have mine back mid next week. I too went with the Vengance pistons and aftermarket forged rods and ported lt4 heads. Did the stage 3 cam from vengeance as well, and a lt4 blower. Can't wait to see my results (around the corner) Been a very long and frustrating 4 months but finally about done.
