Typical Mustang Dyno Numbers?

[Rockz222]

Hi Everyone! I was wondering if these readings are typical of how mustang dyno's read our cars. I don't have much experience with dyno's and this is the first time that I have spent time with ECU tuning, dyno, etc.

Mods: AFE Drop in filter, Perrin Crank Pulley, HKS EL Header, Tomei OP, Tsudo FP + Catback. OFT Stage 2 EL OFS Tune.
Pump gas: 94 octane (no ethanol)

Seems extremely low and I read that mustang dyno's read (10-12%) lower than dynajets from the sticky. But this seems really low compared to the typical dynajet numbers that I see for this level of modification. Or are the numbers as expected?

Corrected to Dynajet numbers?

Numbers mean very little without comparison. Without a stock dyno run or even other cars running on the same dyno to compare to then you'll just have to decide whether you're happy with the way the car feels.

You realy need to know what a stock 86 puts out on that dyno and look for gain over stock. Maha dynos read rearly low as well

look for knock
make sure IAM is 1
and look at your afr and make sure it not super rich like low 11 you would be looking for arround 11.8 on petrol wot high rpm

in case you have an exhaust leak or intake leak throwing off afr

dynos in my counry read about 105kw stock 115-125 for bolt on mods with tune on petrol anod maybe 125-135 boltons tune and e85 fuel

Thanks for the comments. The shop did overlay a stock frs pull compared to my run. There were gains up top and in the torque dip region. I didn't get a chance to see my own car baselines at stock though.

I am happy with the way the car feels. I just don't know what to expect when looking a typical mustang dyno numbers for our car. I understand conditions play a part and same with AFR.

I was seeing mostly 1 for IAM but it dips to 0.98 momentarily and recovers to 1.

I have data logs here:http://www.ft86club.com/forums/showp...&postcount=516

Thanks, I will review the AFR WOT high rpm reading in my log.

I just hope the car is up to par with other 86's with the same level of mods. That was what I was really wondering. I understand that each car will be different and conditions + tune play a big part.

looks like its running a bit rich higher rpm so you would probably benifit from some maf scaling your getting to 11.2 which is rich limit of sensor so it may be even richer its safe but probably costing you some horsepower, you should be arround 11.8 ie whats in the OL fuel table.

That knock looks pretty minor just keep an eye on it if you do maf scaling and lean it out see links below have a look at @Wayno tunes you could likely copy one of those into your rom calid

Thanks Steve 99. I appreciate the comments and help.
