New dyno results!

[ALLTHECAMS]

After replacing the fuel pumps I got my car on the dyno again. With headers, exhaust and a Marc Haibeck chip it made 374rwhp and 362 tq. After top end porting it now makes 409rwhp and 371 tq! I couldn't be more happy with the way it turned out.


Here is the graph:

Good job and looking good too!

Did you just port intake manifold and injector housings or heads also? Been looking at doing this as of lately as I am getting unamused with the power level it is at.

What type of dyno?

Why does the description show a supercharged mustang in the file type?

Nice numbers!

Nice results from those mods....Of course each dyno is different ( mustang,dyno jet )over 400 to wheels wakes this car up..

Its amazing though when you look at some of the results from modded C6Z06's and modded C7 Z06's....550-700 wheel horse is common....

The new C7ZR1 w mods is seeing 8-900 wheel HP......Crazy..

Nice numbers!His computer saved the pulls to the wrong file. Probably the last car he dynoed. He had that car in his shop still and it made 800+.
The dyno is a Dynojet.

Link to the video. At the end it shows 414 rwhp but that was a false reading from hitting the limiter.

Car sounds great! Which exhaust do you have and are those 18" wheels?

[EvanZR1]

Nice! Love you Shelby wheels, have those myself. Paint job on the engine looks great!

[ALLTHECAMS]

Saw this bad dad today. Really good looking car. The white plenum and valve covers is brilliant touch.

Nice improvement but you're running dangerously lean in the upper RPM range if your AFR graph is correct. Suggest you add fuel to get it into the 12.5 to 12.8 range.

I would not characterize the AFR in the upper rpm range as dangerously lean.
13-13.1 I believe is fine. Frankly, I would lean out that “sag” in the mid range and probably take out a bit of AE in the upper part of the AE table. I would try a bit more fuel in the top end just to see which way the power goes as a trial.

What was the SA for these run? Did u check for knock?

[Top Toy]

Per the comparison chart, the AFR is hovering around 13.3 in the upper range.

[jss06c6]

Good numbers! My results on our Mustang MD100 dyno were 406/374 at wheels. My mods are exactly the same, ported top end including port matching heads and a full Stainless Works exhaust from headers to tips.. congrats, now get her out and enjoy it!

Fyi, I dialed my WOT AFR in at 12.8:1.. you should be fine at 13.3 as long as you didn't see any knock..

Looking at the comparison chart, ur right Dennis certainly when the AFR was up around 13.8-13.9. Not as concerned at 13.3, but like u, I would feel more comfortable and likely may pick up a bit more power by dropping AFR further to ~ 13.
Again, would be very helpful to see if any knock was present and where.

SA is spark advance. You can advance the spark timing and make more power until you get knock. You kind of take it to the edge where knock begins and then back off.

Well as an additional margin of safety, it would be prudent to monitor for knock.
I do my own calibrations but concurrently monitor AFR and Knock.

The LT-5 is not prone to knock at the top end. If u keep advancing timing say in the 6-7500rpm range, you will find that it simply loses power. However, there is a point between 4000-5500rpm where u will see knock if timing is too advanced. Also, it helps in terms of adjusting the AE (acceleration enrichment) which may also cause knock if insufficient.

So as a rule of thumb, good idea to datalog not only AFR, but also the ALDL
stream if u can.

Marc advances timing about 10% or 2-3 degrees.

I have used EASE Diagnostics, but now ALDLdroid which is a tablet based datalogger. U can also use TunerPro.
