Re: Dyno sheet from Mesa
WoW looks like you 'll have me... I'm getting scared.... well maybe not as scared as your Bravo's with 720# of torque at 3300rpm...
Sounds good Bob I hope you have fun.

Im really not to worried though. with the kind of boating we do and the Lake that we run on, either bravo will probably be alright if the cooler stays full (know what I mean)
Besides, thats what I bought a spare drive for...... just in case

Bob,
Very impressive numbers. I hope that everything comes together great for you. The boat should be sweet. Still planning on hitting Sacandaga this summer? July 23rd?

Las,
Nice numbers. Question, you have a similar drop in torque that I have noticed in several other engines ranging from 502 to 588 CID in and around the 3100 to 3600 or so range. Do you have an opinion on what it may be?

Very good numbers! Some details would be great! Compression and cam would be good to know. I know some of this stuff is proprietery!
cstraub,
Do you think the slight dip in torque is is due to the transition between primaries and the secondaries? Just a thought. It will be interesting to hear what Laz has to say!

Craig,
You see that dip at various points in both N/A and forced applications I have been looking at this in many engines for some time now trying to figure the relationship in the range of the dip and the mechanical configuration of the various engines. I think it has much to do with the interaction of camshaft overlap and exhaust design. Perhaps on N/A it has to do with mild combustion chamber/exhaust imbalance at a certain frequency, and blow thru in a forced application. You see it in nearly every engine. Great numbers Laz.
