I added a RS575 Cam and Thundermax to what you have & got 93 Torque and 79HP SAE on a conservative dyno. After that added a D&D 2-1 Fat Cat, really nice boost in butt dyno results. Plan to dyno again after the pipe change if weather will allow...

Sae / std

So if my sheet was in STD vs. SAE what would my numbers be?? What is the percentage more for calculation purposes??

Depending on the weather about 3% less, but its only a number, a tune is a tune

So why have a dyno sheet at all if a tune is a tune and only a number? I wish there was only one standard be it SAE or STD.

The HP and torque numbers are for bragging rights, on my sheet to me the most important line is the air fuel ratio.

Wouldn't all the information be important!? Of course the AFR's are important but let's say you have a sheet that shows high HP but low TQ until say 4000 rpm....wouldn't that be important to know? As far as bragging rights rights I would say if you compare apples to apples it is a informational tool to see what components work and what does not, not just who has the highest HP/TQ numbers.

i can agree with you on that, measure of changes and such, But all things are relative since 2 different dynos will give different results

More comparable figures are the SAE numbers.

I'm not an expert so someone please correct me if I'm wrong, but I believe the closer to sea level and the less humidity the less difference between STD and SAE.
