Densecharger vs. WMS CAI: My Results

Ok,

Let me give you some history. About 2 years or so ago, I replaced my Stock intake track with a Desecharger CAI (DS) and the stock MAF with a Pro-M 80mm Unit (PM80). This set-up yeild some decent gains (you could see some dyno charts on my website) and I was happy. Recently I decided to replace the DS and PM80 with a WMS Ceramic Coated Velocity CAI (WMS) & a 95mm Pro-M MAF (PM95). Also, it's to note that access to a dyno over here in Germany is very limited and due to the season they are closed. So, to help me with my quest for HP/TQ and to aid in testing I purchased a Mr. Dyno MRD)(www.mrdyno.com) & an Autotap (www.autotap.com) with all the software parameters for the Ford vehicles. I'm also working in aquiring an WB AF Data Logger and Meter.

The MRD is very in-deph little system. You must enter all types of parrameter in order to (IOT) be fully accurate. I have to say, that there are about 50 diferent imputs to the system.

Since I don't have all the time in the world I just used the system "as is" from the box and only entered the name of my vehicle and the weight. That was it. No weather, altitude, vehicle losses at RPM, vehicle losses vs. gear ratio, "Gs" at acceleration, etc....Again, just as is from the box. These readings will not be in any way accurate and using that term means "reflecting the ACTUAL HP/TQ vs. a BASELINE HP/TQ".

I explain: with the as is setting on the MRD the car produces (as example) 175HP/180TQ, that will provide me with a base line and I can use to reflect gains or losses when I do changes to my vehicle. I hope that explain it.

Any how, I have conducted about 19 runs with the MRD and IS VERY Repetitive and Accurate.

Ok, enough of talking and here are the runs.

This graph represent the following set-up:

DS & PM80 (COLOR BROWN), NO JMS Chip (is out getting re-burned right now to correct a RICH condition)
WMS & PM95 (COLOR RED), NO JMS Chip

Please notice that the RMP readings are off by around 300 RPMS (when you see the TQ/HP readings and they meet they are off by that number) LESS than actual.

Don't worry about the HP/TQ readings since they do not reflect actual numbers and I use them just as a base line.

Keep your attention on the graph.

This Graph here is represent the following:

DS, PM80 & JMS CHIP (Before I send out) (Dark Brown) (Top Graph)
WMS, PM95 & NO CHIP (RED) (Middle Graph)
DS, P80 & NO CHIP (Brown) (Lower Graph)

Notice the similar graphs, take a look on how the HP redings dips in the top end WITHOUT the CHIP, this is due to the stock computer making the car RICH from 6000RPMS-on.

The WMS & PM95 loss about 5 HP at the lower end but gaining over 18 HP at the top end when compared to the DS & PM80. When compared to the DS & PM80 and JMS Chip combo is down in power at the top end by about 10 HP at 6100RPMS and at o/a 6700RPMS by 20+ HP.

I figure once I get my JMS Chip back I should be able to surpass the DS, PM80 & Chip combo easly.

The test were all conducted in the same 3 mile long road, SUPER FLAT, and in really good condition (we are talking German quality roads here my friend!). I live out from the city about 30 minutes from Darmstatd and 15 minutes from Mainheim in a rural area, no traffic and just wide open.

Coments.

Just so everyone understand. I'm not saying that the WMS yeilded all that gain. Is just a representation of a gain or loss in the RPM range. I'm just saying that it showed a gain. That could be a few hp or 5/6 I really dont know, just a representatin of gain vs. loss. Not saying that the Chip is worth 40 HP and that the WMS is worth 20HP.

Just ensuring that you guys understand my point of view. I know someone will come up with some smart a$$ response about it and I want to avoid it.

Wow, cool stuff, Naz. Did your butt-O-metre seem to coincide with the Mr. Dyno?

Cant wait to see some comparisons once you get your chip back :banana:

Todd

It does feel a little stronger on the top end if that is what you mean with the butt -O-meter coment.

I swaped the DS again today and played with the DS set up and back to the WMS and the graphs are just the same. Just wild.

Naz,

when i pulled off my homemaid CAI and installed the same wms unit, i only gained a measly 4rwhp, but i gained 11rwtq. (this was long before the big bore). Once again, your car is proving itself to be quite the factory freak! :nice:

Hey Naz, any comparisons with the new chip yet??

Todd

Not yet.

Last week I spoke with the guys at JMS and the chip was finalized and reday to ship, but since I'm in Germany it may take up to 2 weeks for delivery, plus it has been raining and snowing over here as well.

As soon as I get the chip back and the weather permits will run some quick comparo test.

Will keep you posted.

Thanks for the info Naz.. I was thinking of going the Pro-M 95 route!

I'm curious to see what the results will be like on an actual dyno when they are back open..

BTW.. Did you get anymore info on your rich condition. I've been datalogging as well and I wanted to go over somethings.. you want, drop me an email and we can talk about it.

BlackSnake,

I have to agree with that. I'll be on a dyno next month and should be able to get some "actual numbers" by just running the DS w/the 80mm vs. the WMS w/the 95mm.

The rich condition.....Man, I checked everything. Replaced a couple of sensors (O2, AIT since I spliced the AIT a couple of years back when testing with a the old resistor mod and had a bit of "selant" on it), plugs, filters (fuel) PVCs...and 2 broken lower intake bolts that I had (may be it was leaking) etc and nothing.

Took the Chip out and wham.......the car ran great! Now, the chip should be back from JMS with a new tune fixing the rich condition. Before the new tune my AF was an average of very high 11:1 and dip a few times into the 10s (all after the installation of the headers). But the car did not ran like A$$ until I got to Germany. :shrug:

I have a bunch of Autotap data files with ALL the parameters from MAF to AF and O2 Sensors and a bunch other stuff. If you want to compare let me know.

Any how, the car is running very good right now and hope that with the chip will run even better. I'll get some AF at the dyno next month and will post some graphs.

How about you, did you figure out?
