All:

Anyone have any Stage Zero dyno charts with cat that I can compare? I'm just wanting to know if I'm average or not.

Thanks,

Make sure they're on the same Dyno... your #s would be a lot higher on most other dynos... (eg. If you're at 244 on DD, then you'd be maybe 280 or something on dynojet...)

 

Right. It doesn't matter.. I just want to see some numbers.. Dynojet or DD.

here's a pic of my stage 0+. this was tuned at 17psi, because I had a mbc installed at the time and it was interferring with my Xede.

Wow.. 13whp more? Did you have a cat? Is their DD calibrated the same as Shiv's? Or is it the 93 octane? Hmm... Can you post the AFR graph too?

that was tuned at dyno4mance. I'm pretty sure andrew and shiv have there dyno's calibrated as close as possible. that was catless on 93 with only 17psi falling to about 13-14psi.

here's the graph

Ah, that makes sense then. Catless with 93 octane can definitely see the 13-20whp gain.

And actually your boost stayed pretty consistent during that run. You only fell slightly lower than 15psi at the upper rpms. Your car ran a lot leaner than mine too..

Cool! Anyone else?

Sure... Xede with WORKS 3" DP, HF CAT, IP and ABM (Axle Back Muffler).

 

What does the mustang dyno read in comparison to the DD? I see 293, but I don't know how to evaluate that. Was it on 93 octane?

-M

 

Yes, 93. I know there is a conversion factor, but not what it is. On the day this dyno run was done, another car with similar mods made about the same. So, this is representative of a Stage Zero+ on a Mustang Dyno, I think.

 

That would be me. I have a megan racing down pipe, stock cat, custom 3" catback and an XEDE.

I laid down 291.6 @ 7000 RPM & 282.1 @ 4750.

The difference between lowkey's car and mine is the HF Cat. His torque shows up earlier. Otherwise our graphs are nearly identical.

 

you can figure a 10-12% higher read out on a mustang compared to a dyno dynamics. basically take your DD number and multiply by 1.10-1.12 and that'll give you your number. for DD to dynojet it's about 12-15% higher.

my DD at 12% (260x1.12=291.2) is almost identical to the mustang numbers listed above.

Gotcha.. so is there anyone that got a Stage Zero+ on 91octane? That seems to make a drastic difference actually.

-M

 

Just xflash no mods baseline was at 210 on 91oct

click me

 

Yea, your running stronger than normal. I think Shiv says the baselines do like 190-200whp. Good results. I think I was probably around 220whp with just Xflash.
