Mods
This is with Injen CAI & PowerTech Muffler. The weather was terrible. 97% Humidity & 79 degrees.

I have a video if someone can host it for me.

 

What Cattman mods are ya getting? Headers? Y-pipe?

Those look like good results by the way... 228 whp with only an Injen....at least, that's what I think with my limited experience....

 

great numbers cant wait to see the gains

 

you have one healthy maxima there....most people i seen dyno with only an intake do about 215whp....and i know that muffler isn't giving u much hp....stock muffler is already pretty free flowing.....228whp with just an intake is real healthy.....especially in those weather conditions....btw are these #s sae corrected? i'm gonna assume no becuz 228whp sae corrected is real high for an intake 5.5 gen 6spd....or maybe your a factory freak?

 

Same question as ^ Are these SAE corrected?

 

what does it mean when somethong is SAE corrected?

 

Cattman Mods Installed as of Saturday:
1. Cattman Headers w/Y-pipe Combo
2. Cattman B-Pipe (Mid-Pipe)

"Correction Factor
A key element to producing comparable dyno charts on a global basis is the Correction Factor, SAE Standard J1349, which applies the following weather station data--atmospheric pressure 29.23, air temperature 77 degrees Fahrenheit and humidity 0 percent--to all tests. These exact figures allow apples-to-apples comparison of runs from different cars, different facilities, etc. So graphs with SAE-corrected power were made to this standard. The dyno in question must have a weather station and the proper software in order to generate SAE-corrected data."


The results are SAE corrected.

The "Dyno Jet" figures are estimates based on what the approximate differences in WHP between the "Mustang Dyno" and a "Dyno Jet" which "Dyno Jet" numbers run 10%-15% higher than "Mustan Dynos."

Yes, I was surprised at the results as well. But I remember speaking with Brian Catts and he told me he ran ~225 WHP in his stock 6 speed.

So who knows. I know that my best time with just the CAI and PowerTech Muffler has been 14.5 (which really sux.) So I'll see how I do with the Cattman mods next month at the track.

 

cattman got 225whp in his 6spd? I would like to see his dyno.....and once he proves me wrong.....then DAMN! thats one factory freak....

 

Hmmm... all this makes me wanna get my car dynoed too... just for the heck of it..

 

Your "estimate" of 10% looks about right. IMHO anything above that is wishful thinking.

You need to dyno again now that the new mods are done. Get an AFR with this one and see how it looks, it might be time for an AFC.
