Well, it was a good day. One of the local Chevy dealers has been doing a Grand Re-opening this whole week topping off today with a huge car show and free Dyno runs. They had a mobile DynoJet Dyno from a DynoTune Speed and Performance. Guys seemed to know their stuff and how to run things.

Anyway, the dealership was footing the bill for it. FREE dyno runs!!! It started at 9:00am, I was there at 8:50am and ended up second in line. The first car of the day to run was an '05 or '06 Mustang GT with an aftercooled Vortech kit only. Put down 463hp to the rear wheels. Not bad at all.

Then it was my turn. Told him to go at it and run it to around 6200 rpm. My car is a pretty much stock '04 with just JLT CAI and XCal2 tune from Lidio on the 93 octane tune and fresh tank of BP 92 octane (runs good with no pinging for the last 8 months like this). Weather was probably right around 50 degrees this morning when I ran.

Anyway, best of 3 runs:

Max RWHP: 260.5
Max RWTQ: 280.3

I am pretty happy with that. If you figure roughly 20% drivetrain loss from an automatic car (please correct me if I am wrong) gives:

Motor HP: 312.6
Motor TQ: 336.36

Roughly 10hp gain and 18 ft/lbs of torque from JLT CAI and tune. I was definitely satisfied. Especially knowing that some day this car will have a Trilogy on it to wake it up!!! Plus, it was one of the best sounding, stock exhausted cars up there today. The motor sounds MEAN with the hood open pulling at 6000 rpm at WOT!!!!

Just wanted to share. I hope you all had a good day!!!!

Good numbers for such mild mods, congrats.

They are good numbers, I'll bet your car runs sweet. If you are able post the graph.:)

I will try to take a picture of the graph and put it up as our scanner does not work very well. The car seems to pull well to about 5200 rpm, then a slight drop until 5600 rpm and pulls back up to the 6200 rpm cut off. Not sure what it would have done if I had him run up to 6500 rpm or so. Couldn't remember what the rev limiter was set to with the tune.

Also, AFR started around 15 and dropped to right around 12 from 3800 rpm all the way to 6200 rpm. Pretty much no movement what so even in that. On the run I got the 260hp it was just below 12 - maybe about 11.8 or so.

I never do my dyno runs above 6200 rpm, my car shifts at about 6150 rpms so I'm not going to use it. My dyno graph from a portable dynojet sounds very similar to your hp peaks, a drop after 5200 and a slight rise at 6000.

You wont get higher hp numbers in the high rpms until you open your exhaust, you have to start by replacing the stock exhaust manifold.

OK, here is the Dyno graph. I apologize for the quality. Our scanner is old and does not work very well and I am not sure why it did not do the scan in color. Obvioulsy the higer lines on the HP and TQ curves relates to the higher numbers. These are the 2 runs that got graphed.

That's great news Eric! I have the same setup (mods) as you, and that should be good info. as to where I am with mine??

Good numbers. :woohoo:

Very similar to mine, good numbers. I uploaded my graph from when I had a K&N drop in filter and DR tune only, if you wish download to your computer if you like to do comparisons at different rpms.

This is a good point. Just a reaffirmation that I want to do the full Kooks setup with custom cat-back from Lidio's guy that he uses and the 4.10 gears. I think those would help satisfy the current feeling I have of being used to the car and help me get by until I can go with the Trilogy in the future.

Nice numbers! Now the numbers game begins as you try to pull those numbers up to 300

I am pretty happy with where I am at since I don't plan to stay N/A forever anyway. I will probably do full exhaust and gears and leave it alone (power wise) until the forced induction goes on.

By the way, I have a short video of the run. Any suggestions on where to put it up at?

Try putting it up on Streetfire.net then just post a link. Thats the easiest

Done (sorry about the ground footage - still not in to video editing yet):

If you are sure forced induction is in your future and your choice is the Trilogy Kit, I only want to bring to your attention that gears are not needed. If you want then, that is another story.:)

I know. You and Tallboy keep telling me that....

My opinion is that if you get a Trilogy Kit and taller gears launching your car on street radials will become a slippery affair; if you plan on widening your wheels and using tires designed for drag racing then you improve your chances of actually going faster, in all honesty I don't think 4:10's guarantee you a faster car...if you really like them...do what feels right.:D

Personally I like the Overall feel of the car with 4.10's installed.
I can see how they wouldnt be needed when a S/C is installed, but its always nice to have that little edge.

By the time the Trilogy goes on the car it will no longer be a daily driver/commute vehicle as it is now (actually, hope to retire it from the daily 95 mile round trip commute and winter user WAY before the Trilogy goes on). My plan has always been to go with widened stock wheels and the Nitto DR's on the rear when the Trilogy goes on. I think the supercharger kit should be packaged with that setup included or offered as a package deal. :)

I think any gear setup from stock on up will have traction issues with stock tires with the Trilogy. But I want to get this boat up and moving. We will see what happens. I will definitely be adding the Kooks setup no matter what happens. Maybe do that and spend the gear money on some suspension upgrades for now.

Who knows. Only time will tell. And I do appreciate the input.

Nice numbers. You'll be surprised at the jump from the Kooks setup. Figure 30ish more on both peaks. As for gears, wait till after you do the exhaust work. Many here will tell you it's a good bang for the buck mod, but with a 95 mile a day commute, you may want to stick with the stock gears. I did, mostly for economy reasons as I drive a fair ammount. 1/4 mile numbers aren't too bad either, as I can taste 13's and 100's (best time so far is 14.040 and best speed is 99.79).

The drivetrain losses are slightly less than 20%. So probably more like 305 hp and 327 ft-lb peak values for the engine, assuming the dyno was run in 3rd gear w/ the TC locked.

I seem to recall a lot of bone stock dyno results being in the 240-249 rwhp range, which would correspond to a 17.5-20.5% range of losses.

(of course, assuming Ford didn't pull a "late 90s Cobra" and over-rate the Marauder's engine, which I don't think it did because my MM#1's best track results are in line with the advertised 302 crank hp).

Just remember the advice your Trilogy brothers are giving you is sound.
If I had to "do over" I may have skipped the 4:10's too!
Not that I dislike them, it is not necessary with the ample torque, that TMS offers.
Full exhaust & gears would be near halfway ($) to owning the Trilogy
