Consolidation of mods, dynos, and track times

FlimFlamMan
'05 CC XE 4x2 (no B/T or O/R)
Air box mod with stock paper filter
264hp and 327tq

That means approx 316hp at the wheel? Not to shabby.

A/F varied from 12 to 12.5 (they commented on it being pretty flat. dunno what the hell that means... lol)

The dyno also used SAE correction.

I'll post the sheet on monday. Dont have a scanner at the house.

Next week I'm gonna get it done again with the Injen intake installed.

The term is "fat." It means it is running rich.

Here is my dyno sheet (stock). Hope it is legible.

Can someone dissect this info a little more (if you feel necessary)?

One thing for sure... when I go in next Saturday I am going to ask the dyno dude to graph the rpm range from 3k on up.

The green line was the first run (guess he was trying to figure it out... I dunno)
The blue is second and red third. Third obviously being my best pull.

Thanks,

Flim

It does look pretty rich all the way through. I am surprised the air fuel is basically a flat line at 11:1. You have a bit more power in there if you can lean it at to ~12.5-12.8:1. Looks good!

Thanks for checking it out and giving me your analysis.

I'm thinking theres a good chance a CAI will help lean it out some?

I hope so!

The Dyno numbers are your wheel values. Therefore the answer to your question is: No, you do not have 316Hp at the wheels.

However, If you had you dyno done on a "Mustang Dyno", they are approximately 10% lower than "Jet dyno" and to get the close SAE equivalent, just add the 10% difference.

Heh... I just realized that was a major typo. I meant to put 316hp at the crank. I took 264 x .20 to get an estimate at the crank. Doh!

Thanks for pointing that out.

Here are my numbers with the Bank and Injen combo.

It is simpler if you just do 264 / .8 to get an estimate of crank power (though I dont think there is that much power loss through a modern driveline unless you are 4x4).

Your Dyno looks good

My .02 if it's helps
All of the Titans are running rich at WOT when you go into open loop and the ecu presets are rich about 11:1 if you get a Adjustable Fuel Pressure Regulator, Adjustable from 30 to 75 psi. with a vacuum port to allow it to reduce fuel pressure under high vacuum conditions such as deceleration and idle. You will be able to adjust the fuel pressure down at WOT to 12.5:1. Your A/F in close loop will keep it at 14.7:1 to 13.5:1 for cruising, the CAI will not change the way the LTFT works BTW the return from the regulator can go to the rubber hose from the gas fill to the tank it works I have it.

Interesting, everyone that I have talked to stated that
the Mustang dyno was a little more optimistic in the
numbers. They say the DynoJet is the most accurate
chassis dyno made. Who knows!!

Many of you Titan guys have sweet air/fuel numbers. I
am pretty sure my 11.7 average hurt my HP numbers.
May have been the Superchips programmer. What I wish
will probably never happen. A bigger bore throttle body.
Because the TB on the Hemi is not mechanically controlled
at all a aftermarket TB will probably never be a reality for
me Is one possible for you Titan guys? The best way
for me to lean out my air/fuel is going to be with headers.
Probably my next mod.

Actually, a mustang dyno is closer to "real-world" numbers since it puts a load on the engine comparable to what it see's on the street. This means lower dyno numbers (but more accurate) than you will find with a dynojet. However, dynojets are everywhere and is pretty much the standard when comparing dyno numbers.

Times are updated!

Here's my dyno results from last weekend.

SAE Corrected = 287 RWHP & 342 RWTQ

Equipment: Dynojet 248c

Mods or settings that had potential to affect results: Flowmaster American Thunder split dual exhaust w/ 70 Series muffler; Stock 2WD resonators replaced with Magnaflow bullet mufflers (2.5"); AEM Dryflow intake; Nitto tires (55 lbs each); 87 octane; VDC was "on"; ECU reset done one week prior.

I have a TBS but did not have it on during the dyno.

I have a question. It's hard to believe my HP numbers from my dyno run. Seems too high compared to everyone else. All I added was intake and exhaust. Could my numbers be wrong? They were done at Stillen, so I assume their dyno is good. Anyone have a guess?

Compared to the other Titans that day, I had the highest (aside from those Stillen Supercharged!). Maybe the force was with me on that day...

Yeah...yours are not SAE corrected... I'll pm you later with the STD vs. SAE on my runs.

Cal Titan ....GOOD NUMBERS!
