first off let me apologize for the crappy video, I recorded it on my cell which was just hanging from my neck for most of the vids.
i ended up spending quite a bit more time on the dyno than I thought I would. (most of the morning in fact)
The guys at Steeda were a real pleasure to deal with and I would definitely recommend them to anyone looking to dyno their car. I can’t stand shady shops and these guys seemed more legit than any other shop ive been too.
GT500s, SVT Mustangs, all sorts of amazing cars there getting tuned that make my car seem like a turd lol
Before I went to the dyno I did several pulls around 16psi on the street and the clutch was just starting to slip.
I figured if I droppped the boost a bit on the dyno I would be in good shape.
In the first part of the vid we start off by trying to run 15.2psi and the clutch lets go right before 5000rpm. We confirmed 217whp before the clutch let go and the rpms jumped.
Luckily the steeda operator was smart enough to back off right away once the clutch slipped.
After that we dropped the boost .5 psi and tried again. First doing a pull to try and set the boost controller, then we would hit record and follow it up with another pull. the clutch would slip and we would repeat the process.
Running so many back to back pulls trying to find a boost level that wouldnt cause the clutch to slip was putting a toll on the cooling system, and more than once we had to stop and let it cool down a bit before starting again.
In the last part of the video you can actually see my overflow dumping its guts on the dyno right after my final pull.
It was a dumb idea to show up with my winter antifreeze 50/50 mix and only 1 cooling fan. Ill be running much more water with water wetter the rest of the summer.
Long story short we got tired of trying to get a 13+psi run in as the clutch just kept slipping(though the car was making more power below 5000rpm then I did on my best complete run at 10-12psi), so I set the boost controller to 12psi and we did the final 2 pulls.
According to my datalog the boost did not hold too well (it fluctuated from 10psi-12psi for most of the recorded run.) as we literally reset the controller, did a quick run through 3rd to try and get a quick setting before overheating, then i instructed the operator to just do the pull in 4th and try to get a good reading before the car overheated again.
AFRs were always safe in the 11.5-12.5 range under boost, but they can obviously still use some work.
You can see from the fluctuation of the dyno sheet the boost going up and down from 10-12psi.
Final number was 216whp on 91 octane running 10-12psi on the mustang dyno.
You can bet I will be going back with a fresh clutch looking to run over 1bar by the time summer hits.
Overall it was a great experience going to Steeda. They let ME do things the way I wanted them done, I felt like I was in control of everything the whole time I was on the rollers and their onsite operator/tuner was a really nice and knowledgeable guy.
All in all, disappointing that the clutch didnt hold well enough on the dyno to record a 15+psi run, but still satisfying to know Im on the right track with the tune.
