Forced Induction Dyno Chart Listing!

[TyperRspec789]

Maybe when I'm not at work, I'll post my stuff up.. I really wanna see what the most efficient kit is.

I think the main kits available are:
- P&L
- Accelerated Performance
- Full Blown
- Crawford
- AVO
- Vortech
- Innovate
- HKS Supercharger
- Treadstone
- D3

I'm sure that's on everyone's mind right now, but there are several variables that would probably make it hard to be totally accurate :

1) Wheel & Tire Size
2) Octane
3) Measurement of Boost (Depending on where the source is tapped from)

Some stuff to consider...

Yes all this info would be necessary to accurately determine differences between kits. Right now though what i am looking for is numbers, charts, and that info so that I can just populate this thread with real data.

Other things to consider is run conditions, temperature, humidity, number of runs on the dyno to get your numbers, etc. The more data the more useable the information, but i know that at this moment most dyno runs are being done by shops. Not by individuals going to an independent dyno to see what their car makes like myself. So that data is held by the shop and not the end user in most cases, and as you said most shops will be less than forth coming with the raw data. My suggested posting format is the bare minimum of data that i would like to see. Having wheel and tire info is good, but the only real determining factor is outside diameter of the tire. Wheel weight has some effect but not as much as the diameter of the contact surface.

On top of all this the idea of this thread is to get as many people on here with their runs posted so that people like me can figure out things like how in the hell does the Full Blown kit make almost 55 more horsepower with only 1.5PSI more boost. Things like this can spawn intelligent discussion about what we are doing to achieve the numbers we are seeing.

I've been looking at the numbers from the Full Blown kit as an example just because that kit is the closest design to my P&L Kit. I have noticed a few things that could account for such a large increase with such a small amount of boost. Such as the correction factor they used. My run is posted using SAE CF which equals 254.93HP, STD CF equals 260.46. Sure that's not a huge difference, but it brings the gap down to 50HP, take into account the fact they are running 93 octane and you can likely add a bit more HP to my number and close the gap a little further. Last but certainly not least I ran my car 3 times on the dyno back to back, posting progressively higher numbers (254.09, 257.00, and finally 260.46 with STD CF). If I were to run a few more times i may have hit a higher number, I was crunched for time as I had to be at work after I dynoed the car.

So this is the kind of information I would like to be able to share with everyone buying these kits, and tuning them. It's not to be used as a **** measuring contest, but as a tool for us to determine what we should expect. It's also to get tuners who are posting dyno charts to stick to a certain format to make comparisons easier between brands.

I haven't found this to be true, and I would never spend my money at a shop that would not give me the files. I have dynoed 7 different cars, and I have always gotten the Dynojet files on my thumb drive at the end. I will definitely freely post my graphs made in WinPEP and my DRF files for anyone that wants to see them. I will also be dynoing my car on both a Dynojet and a Mustang dyno for comparison.

While dynoing in 5th would be best, those speeds are not going to work for this car especially if you are reving over 7,400 RPM. I would say all runs should be in 4th gear which is pretty common for modern 6 speed manuals.

The gear also depends on the type of dyno being used. Mustang dynos won't show any difference whether you dyno in 3rd, 4th, or 5th.

I don't think we're going to see really good comparative data until there are more kits floating around. Then we'll start seeing same day, same dyno results from meets and dyno days.

I don't mind posting our dyno charts, or dyno charts of our kit by third parties. I do prefer to use the ones that have the baseline dyno run, on the same dyno and of the same car, so that the actual useful dyno data is on display. And that all supporting modifications are listed.

What I mean is, dyno's are, for the most part, just something pretty to look at without all the data involved. If there's no baseline, then how much was actually gained? Is one turbo/sc/e85 kit really better than the other if one was tested with a stock exhaust system and oem panel filter, and the other had a full 2.5"+ exhaust with no cats and an upgraded intake?

As a tuning tool, your use of the data is perfectly fine, what i am trying to accomplish is to get charts and charts of dyno figures of the different kits, so that we can figure out the averages. You know average HP output at 6 PSI vs 10PSI on 91 Octane. With more dyno information from all brands we can get an idea of where we can improve upon our builds. The reason I personally want to have access to this information is because I want to be able to have someplace I can look after I run on a dyno, compare my numbers to others, and be able to ask someone what they might have done different to achieve their numbers.

As it stands now, you have to filter through every damn thread in FI section, going through page after page, just to find a useable dyno chart. If i can get people to use this as a place to post dyno figures, access to this data will be easier and streamlined!

You know, if you are super motivated you can start an excel spreadsheet and start tracking every dyno result. You could build basic regression models once you have enough data. I'd probably just take into account ambient air temp, altitude and octane as independent variables in building a good normalized baseline for various dyno locations. Mods would obviously become the dependent variable. It's alot of work but doable. After a while, we could have a pretty awesome dyno database with a fairly accurate regression model people could use to plug different variables in and see the result.

This is the perfect thread, I'll be subbing it for sure. My goal is to be just above 300HP on pump gas. (91 here in Utah) So I'm looking for the Turbo kit that can do that without rebuilding everything, if possible. Just Turbo, injectors, headerback exhaust and tune, on top of my crank pulley, perrin filter, etc. Just trying to stay away from new internals.. for now
