Hey Everyone,

In the short time I have had my 997 I have managed to add a few modifications.

The specimin is a 997.1 Carrera S with the X51 Performance Package.

As far as performance goes it has:

-updated idler pulley and serpentine belt (shouldn't do much at all imo)
-IPD Plenum (they claim huge gains but I want to see it to believe it)
-AWE Headers
-AWE 200 Cell Cats
-AWE Mufflers
-X51 package includes dual inlet carbon airbox and third center radiator (OEM) and obviously everything else it entails.

Many people keep asking me how much power I am putting down and I really have no idea if I am at 355hp or 400.

I'll update tomorrow at 7-8pm EST assuming all goes well.

How much power do YOU think it will make?

John

PS- The said dyno is a DynoJet and I am told by the shop owner that it reads very low compared to a Mustang. He claims that it's a 100k dyno. I really have no idea how much truth there is to that other than the shop is about a year old and is literally 1 mile from my condo. I have always wanted to try them out, so I am looking forward to the opportunity!

Also, a couple of pictures attached of how the car currently looks.

 

fyi, u might be disappointed.

dynos are used to measure hp, tq, af ratio, etc with a nice graph..

but there are too many variables (different dyno machines show different numbers dependent on setting, weather, etc) to see what the actual HP number may be. In the end, it will be just an estimate.

IMO, Dynos are better used to determine the gains and the power delivery (via graph) from a specific mod. That means u should do a before and after (on a same machine with similar humidity and maybe even the same operator ).

u can also use the graph/AF#s to have ur ECU re-programmed for better/smoother power without dips & early peaks. It will better utilize all the hardware u added.

just don't get caught up in the HP number.

Nice car btw

Good response and thank you for taking the time.

The main reason I am doing the dyno is because, like you said, I can use the graph to assist in the near future tune of my car as well as be able to see a "before & after" of the actual tune.

Believe me, I know there are MANY variables and the tech I spoke to already prepped me for the fact that the numbers will likely come in low. He told me of a couple of things he uses special for 996-997 Porsches to help narrow down the variable rate and keep things as accurate as possible. He also explained that most Mustang dyno's read much higher than his and that therefore he has disappointed a few people who came to him for their fourth or fifth pull.

The cool thing about all of this is that I can get from my place to his shop in about 9 shifts (lol) and we will begin fresh with a car that hasn't been "driven" the same day. I am sure whatever number I get will be extremely accurate given the machine he uses and how knowledgeable he seems to be.

I would not want a dynograph done if it were not accurate and would rather get a close estimate than a higher number that doesn't mean anything.

PS- thanks for the compliment

that makes the two of us

 

Also, the current weather in South Florida is super hot and humid. Where are you located by? I live in Miami.

 

I am located in Naples, FL and it is definitely hot and humid... not much I can do about that though

I have dreams at night that one day I will wake up and it will be 55 degrees outside with a slight breeze and a fair sky.

 

Wait a few months and you will see that weather condition.

 

I'm definitely interested in your results. I'm surprised his Dyno jet reads lower than most mustangs. Typically its the other way around from all the dynos I've seen and done over there years. Like everyone has said. Definitely is a good tool to see if mods made a difference and to judge overall powerband. Makes sure PSM is off and sport mode is on!

I dynoed my stock C2S on a mustang dyno a few months back for the hell of it. It was during a dyno day a friend's shop was having and figured why not. At least this way if I do change exhaust and intake, I can see if there are any gains.

Good luck!!!!!!!

 

I chose a place called Gulf Coast Motorworks here in Naples, FL. They are an authorized DeLorean dealer as well. Pretty funky place. They were working on a true blue Ford GT40 (the real thing) and a few Countach's and F335's. Interesting people and place. Had quite a few old Cobra's and Cobra kit cars as well.

The machine that they used is called a DynoJet 424 LC2 with "links and Eddy load)... Please excuse my ignorance in this area.

We ran the car at 78 degrees with 48% humidity. It had JUST rained so actually was cooler than normal by about ten degrees

Anyhow, on my third pull up to 7,100 we were able to achieve:

340.66 RWHP
287.14 RWTQ

Needless to say, I am pleased with the results and also the graph itself. The power band is extremely even with only a very small dip around 5,100RPM. I am one happy camper! This car has proven itself in every way since I have owned it.

Nice. I bet you would make a few ponies more if there was less moisture in the air. Either way, nice numbers. Take any video?

 

Sure did! Just attempting to host it now

And thank you, I agree. It literally stormed 5 minutes prior but I feel good about the numbers
