Sonic Dyno Thread

Updated results.

cndctrdj- you've got a 93octane tune correct?

Did you update my stuff in the 1.8 section ?

Yep, got ya in the dyno section. You're the 1st 1.8 submission.

Looking at this thread, since I found a dyno near me and plan to finally get some wheel figures sometime soon. But I see that PID numbers are of interest, so I thought I'd get started there.

VT reports 206 hp/212 lb-ft

ZZP intake with insert removed and honeycomb added
DDM high flow 2nd cat, and catback with resonator delete
#42 bosch injectors
Buick Regal alcohol sensor
Forge BPV
VT rebuilt turbo, clipped
32F weather
80% ethanol content according to PID (E85 says it can run anywhere from 85% down to 70%)

Still fine tuning, so I'm not really ready to pay for a dyno, but sometime in the next month I hope to get some "wheel" numbers and a nice chart to see where the delivery of power really lies.

You have the vt turbo "upgrade" ?

 

[Swordsmith]

You have the vt turbo "upgrade" ?

Yeah, its a stock turbo that's been modified, not an actual turbo swap. In his words

We offer an upgrade for your stock turbo where we machine the housing to accept a larger compressor wheel and clip the turbine wheel. This will gain enough flow to support ~220hp on ethanol fuel.

.

I've only gotten to 206hp, but it looks like it's as dialed in as it's going to get without increasing the valve spring pressure.

Talking to Brian at VT about going to the dyno now that we're set up, this was his comment

I would leave it there for now and you could certainly dyno it now to see where you are at. Going up to larger injectors is one option, but if we can not run higher boost pressure I do not think it is necessarily worth the effort for you at this time - your logs were showing that you can flow up to ~170 g/sec with the larger turbo (but we started floating your valves) and you currently are flowing around 158 g/sec at 21 psi at 6100 rpm (12.5 degrees advance and IAT = 81F, turbo wastegate is running 90% duty cycle). You could probably pick up another 8% at the wheels from where you are now if you could push the turbo to it maximum flow at higher boost without floating the valves. The numbers above are what you are shooting for on the dyno - but we often can not reproduce the same conditions on the dyno due to higher loads and intake air temps. Make sure to record logs when you do your dyno runs so we can compare the conditions for each pull, paying most attention to getting your intake air temps down between pulls. You might want to try recording a couple of runs in 3rd gear instead of 4th to reduce the loading a little, which helps to mimic real road conditions better. Just record baseline runs in both 3rd and 4th so you can make meaningful comparisons to your tuned pulls. I usually do the tuned pulls first since the baseline runs can still hit their peak numbers at higher intake air temps when the car is hot and you do not have to wait so long between pulls, versus doing them the other way around and the car is heat soaked while doing your tuned pulls. Paying attention to these kinds of details is important if you want meaningful data from your dyno time.

I've never put a car on a dyno before, so any other tips as to what to ask for would be of interest. At $100 for 3 pulls, this isn't screamingly expensive.. but it's not car-wash cheap either. He's suggesting what looks to me like a minimum of 4 pulls (two tuned, two baseline, one of each pair in fourth and one in third?) And I'm also interested in seeing the numbers using gasoline versus E85, which means running the tank nigh unto dry, swapping fuels (which I don't normally have to do since I am just as happy on 20% E85 or whatever) and coming back for another set.

Make sure the dyno operator uses the correct correction for a turbo charged car and put a fan on the front to keep heatsoak in check.

 

[Foxbox]

No real reason to do any pulls in third gear. Fourth is the optimal gear to use for this.

2013 sonic RS
mpfab intake
mpfab anaconda
Forge BPV
Custom Performance AutoWerks hpt tune
base run is with parts installed and stock tune

 

[sx sonic]

I'll update in a few days.

 

[Preloader]

It takes you that long to learn to use a new phone?

 

[Sonic]

Are the numbers and info being maintained regularly?

I've been slacking a bit, no WiFi where I'm at so I can't use my laptop.

Should get things updated today when I go to my dads.

Edit:Results updated!

Legend

One suggestion on the 2nd post is that of the 'Legend'. It seems like it would make sense if the 'Legend' was in alphabetical order. So 'AM' for the airbox mod should be listed first whereas the 'Tri' for the Trifecta tune should be listed further down when it gets to the letter 'T'. I was trying to find order as I kept looking at the mod list and back to the legend. As the mod list continues to expand and grow, it would make things easier to find as it would be order in the searching/looking.

Great thread and good posts!

 

[Eric Smit]

Myx, could you PM that to the OP? if you don't get a response in three days, just give me a holler. I'll try to remember.

 

[sx sonic]

I'll try to remember to change it in a few days when I get on a computer.

Good suggestion.

 

[mitdr774]

While updating I feel it would be in the best interest of the group to remove my PID information. While I was still dealing with my tune issues I was informed by a Trifecta representative that the PID numbers are not accurate and I can not rely on them to judge what the tune is doing. Some day I will actually get my car to a dyno and have real numbers. I need to sit down with someone that knows HPT far better than I do first.

 

[Stew]

Alright, add me to the dyno list!

151 HP/ 201 TQ

Dyno graph is in my build thread here:

Power related mods are:
- HP Tuner tuned
- Ported intake manifold

Had a dyno at my car show yesterday, thought I'd run it.
1.4 manual in 4th gear
117.7HP as stated in image, 145TQ (if I'm reading it right)
stock tune - Mobil Super 93 octane
Temp in mid 70's - Humidity was 70% or more - Elevation 130'
Dyno Dynamics portable
Operator said it was corrected by temperature sensor
K&N Intake
ZZP 2nd cat delete
ZZP no muffler-catback with 22" Magnaflow round underneath, and Vibrant 10" Ultra Quiet resonator out back.

Time for an update. Had another car show yesterday, and had the dyno back.

Changes since last year include:
Trifecta full tune
NGK copper spark plugs
DDM Works silicone charge hoses
ZZP Midpipe
Removed Vibrant resonator, and installed the ZZP muffler section
All the humidity (occasional misting) and same temps.

noted 145.4 hp (27.7hp increase)
about 198 tq (53tq increase)

 

[biged83]

I had my stock dyno. the guy doing the dyno was very shocked and so was i. lol
138hp 154tq on 93oct on a mustang dyno

I will have the charts up tonight

 

[94383Z71]

stock as in the car was stock? good numbers, but know that Mustang dynos are known for usually being optimistic.

Looking forward to the graphs.
