I don't understand the question. There are no correct points. Why would they cross at 5252? Remember, this is NOT a NA motor...this has a blower. If you tune it at say 12.5 to 1 af then cold weather will stuff more air in and lean you out. There has to be some room on the tune for variables. Heat, cold etc.dawgs77 said:Can you explain why this dyno does not cross at the corect points. Too me....the numbers are not fully valid.
If the Dyno is calibrated right...the dyno should cross at 5252.
Man your on the rich side....pretty safe...but there is more power in there if your that rich.
No, they allow it to shift into 3rd gear with od off and roll into it WOT so it doesn't downshift. I have no idea about all that math stuff. It makes what it makes. It runs strong and beats many people.dawgs77 said:Another point...how did you start that dyno at 2,000 rpms????? Do you have the ability to lock your transmission in your 1:1 gear on a automatic tranny?
I don't doubt that that engine makes that amount of power but something wasn't set up correctly. Dawgs is absolutely right, all dyno runs should have the hp and tq curves cross at 5252 rpm because that is hp is a function of tq, and when plotted on a graph, two numbers that are functions of each other will cross at the divisor.fepony said:No, they allow it to shift into 3rd gear with od off and roll into it WOT so it doesn't downshift.

My rear gears are 3.73 if that is important.
Google this... Call Tony and ask him... http://www.hp-performance.com/ BTW he is the guy doing my motor swap. Feel free to call him. That is also the very same dyno i was dynoed on.ablexus said:The plot thickens...
I googled "HP Performance" and on their web page, they have several dyno sheets. This one is not incorrect as far as I can tell, there is no tq curve plotted:
But these are definitely not right:
Anybody care to speculate as to what is going on here? :huh:
None of those 3 are even by my tuner. They aren't my truck nor do i even know what they are for. I posted mine and where i got it done. I don't have to lie.dawgs77 said:Dyno 1 up there shows HP and the AFR..not Torque
Dyno 2 shows two HP curves with different mods
Dyno 3 shows a MAJOR mod and change in HP.
