Yesterday (02/02/06) I went to Logan Motorsports in South Elgin, IL. They have a dynanometer that connects directly to each of the front hubs, so the car turns the machine from the hubs. I was expecting to see one of those roller dyno's that I've been more exposed to, but they said that this kind of dyno would be more accurate than a traditional roller dyno.
In the end, they Advancing both of my cams 6*.
122.5 WHP @ 5400 RPMS
137.1 ft/lb WTQ @ 4200RPMs
At my peak WHP (122.5), I have 119.8 ft/lb WTQ and that's at 5375RPMs.
I'm quite pleased with the results and I think that with a little more tuning time I can squeeze out a few more hp/tq!
They had two machines there (that I saw), they removed the front two wheels and connected each machine to a wheel hub. That way when the gas pedal is pressed, the hubs move the machines.
I talked to Karl at Massive Speed System and he said that if I were to go to a dyno with DynoJet, I would see around 140WHP and a lot more TQ. Karl said he goes to this dyno because it gives a more accurate reading as it is directly from the wheel hubs.
That's exactly why he goes to this particular dyno; because it's more accurate. Though the reading on a DynoJet may say that I get 140WHP, that will not be an accurate reading. So [] I should find a DynoJet and compare the results though.
(By the way, I used 140 WHP as an example #, I should have mentioned that earlier)
lol now im really confused...is the first pictures in your gallery a different car? Cause later on i see the automatic shifter but in the first few it looks like a stick...lol
I do have an automatic, but I dislike how they look stock. So I put a MOMO Aluminum Shift Knob, Leather Boots, RS Hand Brake, and some other goodies to enhance the look of the interior. Sorry for the confusion.

it's an ATX with a boot and different knob. that's someting that i think i'm gonna do to mine too. how much did that whole thing set you back brad?
Logan Motorsports charges $150/hour, or $85 for three pulls. It's also a little bit extra (range of $25 - $50) for SCT tuning, A/F Sensor and things like that. I prepaid last week with the amount of $200 and I'll either pay the difference or they will refund me back X amount. Money very well spent though. Everything is running so much more smoothly.
The only problem with a dynometer is that it cant put a load on the wheels like a dynojet can. That is why you will see more from a dynojet because it measures and calculates based on the load.
I'm really suprised about how much more TRQ you have over WHP. I had more TRQ with the stock cams in but when I upgraded to FR Stg 2s I got more WHP than TRQ. *shrug*
Thanks for the comments guys. Perhaps on a dyno day G2G or if I find a DynoJet dealer in my area, I'll get a few runs in just to compare the results of the two different types of dynos. I <3 my torque monster [thumb]
I have been looking for the flywheel bolts for the 03 zetec 2.0 motor. I am about to do the clutch and main seal, but I can't seem to find a clear answer on these bolts. Can anyone help?
As mentioned, I have lost ground at the seatbelts, the e brake handle, and also my ABS light stays on.
I have replaced the seat belt actuator, alternator, instrument cluster, added ground wires to engine. Upgraded the alternator wire to a 2awg.
Checked all the ground wires at the A pillars...
My car started having problems when i was accelerating at full throttle the car died and bogged out. At half throttle, it sounds like a bad miss in random cylinders, at idle, sound of the miss stays the same if not worse and the rpm varies. I started with the MAF, no change, ran my OBDII on the...
I'm tempted to run some Torco SR-1 5W/30 in my 2003 Focus with Zetec DOHC 2.0L engine.

I ran some Mobil 1 0W/20 Synthetic back in 2007, and it leaked out the valve cover and some other places after some hard driving. So I ran the Motorcraft 5W/20 blended since then with no...
