Took my car to Akuma to get some installs and a tune.

Everything is nice except for a check engine light caused by the 3port (o2 light was fixed, but had to leave) and a loose ground to the wideband. Fixing that next week.

I made 307whp and 297 torque on their mustang dyno @ 25-25.5psi
I am having an issue putting the evoscan log through virtual dyno though.
Attached is my run log off evoscan on the final pull on his dyno. Nothing is altered.

I tried to convert using VirtualDyno.
Numbers look inflated as hell.

Would anyone mind doing their own conversion for me with virtual dyno? This is the exact log run from evoscan off my final pull.


This is my mod list:

Power:
AMS intercooler
AMS resonated testpipe
AMS o2 widemouth downpipe w/bung
Buschur LICP & UICP
Tial Q BOV
ETS intake w/ heatshield
GM 3-port solenoid
Greddy Racing Ti-C exhaust

Not to be a jerk but that seems really low for your mods.

 

Well the mustang dyno reads real low hence I made the conversion to virtual dynojet.
But now the numbers seem real inflated, and that evoscan run log hasn't been altered in anyway and was given to me right after the run.

Originally I was told to expect to never break 300 on their dyno.

Anyone care to take a look-see at the attached run log and provide some insight?

 

As long as your happy with it thats all that matters. Isnt that what we all want is overall happiness with our cars

 

yea i was tuned by Akuma and made 300whp i am happy with how the car feels i don't get all wrapped up in number chasing, if that was the case i would drive to Fl and put my car on their dyno and make 400whp stock turbo lol (dyno humor)
keep in mind a stock X on their dyno puts out about 210whp, it is a heartbreaker dyno.

 

393hp/402tq in VD seems freakishly high for stock turbo, especially given the mustang numbers (which don't seem too bad unless people expect every dyno in the world to be a florida dynojet). Dynos are a tuning tool, but virtual dyno should be a fairly good comparison. I'm wondering if those were run down hill Adjust the car weights and use the SAE adjust to get a better idea from comparison.

What's your boost limit set at? looks like you're near 27psi. If you notice in the VD results, the one run that didn't spike boost got the best results. the stock turbo is most efficient around 25psi. going over that is just blowing hot air.

 

Boost is @ 25 - 25.5psi

I got it figured out.

This formula is derived from a post made by john @ akuma and can be found here:

He ran a test of the same car on his mustang and a dynojet.

This was his result:

Mustang = 286/299
DynoJet = 343/350

Thus, making a 57/51 difference in numbers.

If I ran @ 307/294 + added the DynoJet difference I would be @ 364/345

I think I can sleep better now lol.

 

sounds about right. if you use percentages, its about the same too (368/344)

 

Don't think your gonna be able to convert based on logs from the dyno... I tried that a long time ago on a dynodynamics... a load bearing dyno controls how fast the car accelerates... at least the DD does, not sure about mustang... since the power calcs are based on time between rpm point and the vehicle weight..... logs from the dyno are useless for Virtual Dyno.

 

Thanks for the post. The dyno does read very low. The logs Tehsteve has are from the tuning session. Blk-majik is correct, I do not like running 27 PSI on the stocker. That run also pulled some timing up top so changes were made and tuning commenced. You get the idea.

Overall the car runs well. The gauges are OK, just a misunderstanding on how they functioned, so we cleared that up today no problem. A very nice STG 2 car.

John
