power curves
Any one have the power curves for an HP500 and/or 525efi?
If not the graph, then just the data will be fine.

Re: power curves
Okay, it's fine now.
I like the nice flat torque curve along with it's starting and ending rpms.
It should be interesting with the 305's. Is there a cam change being considered?

Re: power curves
Russ,
Yes I picked out a new custom ground cam and talked to Bob Madara after the fact and he liked the specs. I would be very happy if I can get 1.33 hp/cid like you did, but I have a much more conservitive number in my head and it is over 600 .

Re: power curves
Stormrider,
The only thing I did was mill off the choke horn and do some mild blending in the carb. These are 1998 factory sealed HP 500's with 270 hrs on them. I never even changed the ignition timing. Jeff
