I'm not sure exactly how STD differs from SAE, but the dyno numbers in my sig, corrected using STD standards gives me 351.21 rwhp and 362.91 tq. If there is a direct correlation between the two, I'd say you are right around 335 rwhp, SAE.

Good numbers either way.

 

Ok there seems to be some doctoring on this Dyno, I calculated his correction factor to be 1.017 not 1.04, therefore; you only dynoed 343.24 RWHP, reason being is I calculated my dyno correction factor here locally & it was .097, my dyno sheet says .097 aswell, I calculated yours several times & its 1.017 not 1.04, your graph is doctored!

Using the formula as found in there i calculated the same 1.017 correction factor. So taking 351/1.04*1.017 gives us 343.4 SAE HP and 343.6 SAE tq. Not too shabby.

WHEW, nice, still over 340. Another FYI, http://www.superflow.com/support/cycledyn-theory.html
according to that, SAE hp is SAE J1349 standard of June 1990. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C).

STD hp is also a SAE correction, just to a different temperature condition. SO therefore if it says STD or SAE STD or STP it is the slightly higher (lower normalization temperature) readings. If it just says SAE hp then it should be SAE J1349.

Soooo.............I say funk the dyno and I'll just go get some track times

 

Thats not being picky Phil, that is being accurate in the information and results you present for others. I truely thank you for pointing that out, it was an honest mistake on my part that i didn't realize there were 2 corrections available.

I called the shop and he said "i'll get them to you next week.............." ripoff mustang shop bastards. I think the 343 SAE-J calculated above is correct though.

-brent

 

Still darn good #'s.I know it was an honest mistake.Higher than the 224/230 I saw yesterday.

 

On an XE 230/236 in a 383 LT1 I pulled 378rwhp and 383lb ft of torque through a 700R4 with a 3200 stall.

The dyno guys said if I had a T56 it would have been 400rwhp.

 

That's great. We are happy for you. But what is your point? I'm not sure.

 

No point. Just sharing results.

 

Where your numbers SAE ?

 

Mine are SAE: 224/230 STOCK bottom end, ported heads, ASM headers through a cat:

375/363 at the wheels.

 

Yup.

If it helps, I dynoed on a 84.2 F day.

 

Where'd you buy the cam from?
