cam swap dyno results inside cam swap and tune were the ONLY changes made between these two dynos. the dynos were done at different places (ARD AND CONLEYS), but both are dynojet and i had them both corrected the same to keep it as comparable as possible. ill be going to the same dyno shop for now on anyways since its alot closer.
all of this is through an A4 with a 9.5 3800 converte. 4.10 gears and 305/45-18 wheel/tire setup.
i swapped a 226/226 .584/.584 112+4 XER out for a 231/239 .617/.623 111+2 LSL. let me know what you guys think about the graphs. im not as keen on this stuff as some of you guys. and if anyone knows how to lay this stuff over each other ill owe you a beer

and look past the peak...im sitting 40hp higher at 7000rpm than i was with the 226 cam.
i shift at 6900...before you say that theres no need to shift that high it was track proven. it put down its best times with the shift points at 6900 with the 226 cam. i bumped the shiftpoint to 7k with this cam but there will be some trial runs on the shift points on the track, but thats where it feels good for now.

thanks patrick. i got bored and did a little homework comparing the sheets since i couldnt lay them over each other
its just not all at peak
gained roughly:
gained 5hp @5500, LOST 8 TQ @ 5500
gained 14HP @ 5750, gained 10 TQ @ 5750
gained 15HP @ 6000, gained 15 TQ @ 5750
gained 24HP @ 6250, gained 17 TQ @ 5750
gained 30HP @ 6500, gained 19 TQ @ 5750
gained 33HP @ 6750, gained 21 TQ @ 5750
gained 40HP @ 7000, gained 30 TQ @ 5750
new cams average HP between 5500 and 7000 rpm= 417 hp
new cams average TQ between 5500 and 7000 rpm=349 tq
old cams average HP between 5500 and 7000 rpm= 393.7 hp
old cams average TQ between 5500 and 7000 rpm= 334.4 tq
thats a little more research than i ever planned to do. its also giving the old cam the benifit of the doubt of hitting 390. it makes me happy with the results
the drivability and low end feel the exact same to my butt, but the real results will be seen on the track.

Hey Pat thanks for straightening me out. I was thinking the lift numbers were going have a greater effect on the gains but I guess not. Maybe had he gone 8 degrees more duration on the intake vs 5 there would've been a larger gain. Not knocking the swap at all, its always nice to gain power.
To the op, nice chart. I did one of those for my 346 vs 402. When you put the numbers side by side it really makes for a good visual vs just looking at a graph.
Any chance you might chart the 3000-5000 range? Thats where I was concerned with making power considering I am going to be on the street not the track. I learned my lesson chasing a peak number. Don't get me wrong my old 346 setup would move out, but call me greedy, I wanted power from idle basically vs waiting until 4000+ rpms. As if 360 rwtq @ 2800 rpms wasn't enough.

i would have loved to chart the 3-5k gains/losses but my last dyno started at 5500rpm. when you start the dyno in my truck the converter usually unlocks and flashes really high. all i had to compare was 5500 up

no they just stuck a probe into the cutout and did it that way, and it fell out. i was looking on a wideband 3 nights earlier and its sitting right at 12.8
