Went to dyno the yesterday and 344RWHP/356RWT SAE. 352RWHP/365RWT STD. The dyno guy said that was not bad for a bolt on car (02, M6). What is the diff between SAE and STD? This was a Dyno Jet. I have Dynoed as high as 362RWHP/370RWT at another Dyno a few years ago, dont know if its was SAE or STD (lost the sheet).

 

I think it is something like uncorrected too. SAE Factors in weather temp out side, where STD just gives a solid number. They are both real numbers I use STD on my numbers.

 

STD and SAE are both SAE corrections but are corrected to different standards.

STD (or SAE J607) is corrected to a 60°F day with 0% humidity and a barometric pressure of 29.92 in-Hg. SAE (SAE J1349) is corrected to a 77°F day with 0% humidity and a barometric pressure of 29.234 in-Hg.

 

sae is better

 

sae is more percise

 

SAE compares apple to apples, STD is bragging rights

SAE

 

Most people use SAE. That'd be the way to go.

 

So how are the numbers?

 

What is your full mod list?

 

Just a bolt on car. lid, hedders, cats, cat back, ported TB
