Quoting EmeryatStm:
About a week ago Dan brought the car to me to see what it made for power on our dyno. After a few small tweaks and about 30 psi on pump gas we were done. The car did OK but not what we expected at all. One of the parts I have been bugging him about was his cams (BC 280's), After telling him that we need to get them out of there ASAP we decided to toss a set of Comp 272's (smaller cam) in the car to see what would happen. Both cams were installed with stock cam gears and not degreed in.
As soon as the car started (Even at idle) we needed to add some fuel. I thought to myself, Well it was a 280 cam and it should make less power (take less fuel) down low....On to the tests.
We drove the car on the dyno and pulled a few degrees out of the timing just as a safety factor, in case the car went way lean, it would not hurt anything. As soon as boost started to build we had to let out and start adding fuel, After the first full pull, I had a smile from ear to ear because the car sounded so much different. I could tell it was going to make alot more power. Alot of fuel later and a few pulls on the dyno this is what we ended up with...
This graph shows the car tuned on the same amount of boost with both sets of cams.
Dotted lines are BC 280's Run 2
Solid lines are Comp 101200's (272) Run 1
Both tests were performed in the same conditions
I posted everything of importance but if you want info like what mods are on the car, a vid of the runs etc let me know...
