In lieu of the v6 forum being broken up into LLT and LFX sections, it only makes sense to have our own Dyno #s thread here.

Stealing from the LLT thread (credit to bmorecam's original thread)

To add your dyno times, please do so in the following format:

Type and make of dyno: (ex. dynojet model 248x, mustang, etc.)
ODO at the time of the dyno:
Gear used(3rd or 4th):
Correction used(STD or SAE):

Here's our spreadsheet for keeping track:

There are over half of dozen corrections that can be used but here in USA we only use 2, the STD and SAE. Since there seem to be so much confusion surrounding this 2 calculations I will try to make this as simple as I can for you guys that want to know more about these very important factors that is part of every single dyno.

First, lets understand why these corrections was created in the first place. The correction standards were developed to discount the observed horsepower readings taken at different locations and weather conditions. It is obvious that an engine builder in Colorado could not produce as much horsepower as a shop at sea level. There is just less oxygen for the engine to burn at the higher altitude. What are less obvious are the other weather condition effects on the engine. So in order to compensate for this all advertised horsepower is "corrected" to several different industry standards.

"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg of dry air and 77 F. This SAE standard requires a correction for friction torque.

STD is Another power correction standard determined by the SAE(society of automotive engineers). Power is corrected to reference conditions of 29.92 InHg of dry air and 60 F. Friction torque is handled in the same way as in the SAE standard."

To sum everything up, both correction factors basically mimic a preset condition which was created by the society of automotive engineers. So... although the SAE correction factor is recognized today as the "standard" correction in the automotive industry, this does not mean reading a dyno number with STD cf is wrong. No matter which correction factor your dyno shop use, you should get an accurate comparison as long as you compare SAE vs SAE and STD vs STD. Never compare a dyno run with two different type of correction.

Here's an example of the format to post:

Type and make of dyno: DynoJet (unsure of model)
ODO at the time of the dyno: 9,995
Temperature: 82*
Manual/auto: Manual 6-speed
Gear used(3rd or 4th): 3rd gear, 4th was hitting the speed limiter
Modifications: Cold Air Inductions' cold air intake and RX catch can. Otherwise stock.
Correction used(STD or SAE): SAE
Result: 270 hp / 232 tq

I just got my numbers today :thumbup:. Could you add me to the list.

Type and make of dyno: DynoJet 248E
ODO at the time of the dyno: 20,510
Temperature: 89.5*
Manual/auto: Auto
Gear used(3rd or 4th): 3rd gear
Modifications: Cold Air Inductions cold air intake, V Max ported throttle body, Corsa cat back exhaust.
Correction used(STD or SAE): SAE
Result: 277 hp / 239 tq

Thanks for posting, really expected you to have slightly higher numbers since
Meissen had 270hp with cai only. 87 octane?

HP Turbine 09-15-2012 10:02 PM

yeah me too. I was hoping for at least 280. He has less loses with a manual.

IneedAZ 09-15-2012 10:14 PM

So the exhaust gave you around 4hp based on the original tb tester got 273 with cai and tb.

HP Turbine 09-15-2012 10:44 PM

I guess so. I believe corsa stated like 6 hp, buuttt I could being pulling that number out my a**.

HP Turbine 09-15-2012 10:47 PM

as for octane I had a bit under a half of tank of 87 and I filled with 91 the day before.

IneedAZ 09-15-2012 10:58 PM

Wonder if the 87 hurt your numbers. Maybe the ecm retarded the timing cause it still recognized 87

HP Turbine 09-15-2012 11:03 PM

not sure. I tried to burn that tank of 87 out and I just couldnt do it.

IneedAZ 09-15-2012 11:06 PM

Jegs back ordered my exhaust a couple weeks but hope to have soon and will do dyno. Want numbers before doing a tune.

HP Turbine 09-15-2012 11:14 PM

I'm debating the tune now. Actually was just looking at the JRE page. I can't just leave my car alone :facepalm:. I'll dyno it again if I tune it. For $75 I got 5 pulls. I'd love to just skip all the little stuff and get some FI!

IneedAZ 09-15-2012 11:21 PM

I have been looking at the IPF and Triffecta Tunes? IPF claims 10% increase, so i would like to see some dyno results showing that.

HP Turbine 09-15-2012 11:26 PM

Everyone seems to love their triffecta. I was going to look into that too. I'd need to see the numbers too.
