You should also post the type or manufacturer of the dyno since some dynos (like dynojet and other inertia dynos) give inflated numbers because they calculate the torque rather then measure it like a land and sea or a mustang dyno (brake dynos) so just remember that when looking at some dyno sheets because they can be as far off as 30%

I agree with you there.... Back in highschool we got a dyno at our autoshop and it had slightly skewed numbers. It was funny because all the muscle-car boys jumped all over the dyno and immediately started posting 200 hp, 250 hp, etc... They were all stoked because there big mean V8s put out soooo much power. I then suggested we put my moms 88 Toyota Corolla on the dyno. My moms Corolla had a factory claimed 90 hp engine with about 76 ft/lbs torque, on it's 1.6 liter motor. My mom's Toyota posted about 185 horsepower on that dyno! All of the sudden we had a bunch of cryin muscle-car boys.

Same question as two up.. Where to hook up the pickup for tach? Ran on a Mustang Dyno last Sunday...

Running just the upsolute chip on my 2002 NB Auto TDI I recorded 4 runs.

1st run 97.4 WHP
2nd run 109.7 WHP
3rd run 97.6 WHP
4th run 97.9 WHP

The cool part is the 3rd and 4th runs were on Veggie Oil!! No loss is no bull [img]/images/graemlins/smile.gif[/img]
They want me to come back when I or they figure out how to get a tach signal. I logged with VAG-Com and if I did the calc right, I'm guessing my Torque was over 195'lbs??? Someone give me another calc, as that CAN'T Be right????

The difference from run 1 to run 2 is a little high. 195 for torque is very believable. RPM can be picked up using a piezo pick-up on the injector lines or by using an optical sensor on the injector pump sprocket.

I was just discussing a Mustang dyno with a local shop here - they were certain that they could determine torque from wheel speed. I guess if you had the proper factor to account for the gear ratio this would be possible if the dyno software allows for this - probably not as accurate due to variation in rolling radius from tire brand to brand.

The mmustang dyno I used calibrated the rollers before the pull to several points on the tach.

I don't think they have the right pickups for either of the options. They do say they have a VERY sensitive pickup that they use for the coil packs on the 1.8t's. I wonder if that would be sensitive enough to pickup off the Alternater signal for the Tach? Either way, I get a free run on both fuels if I can get them a way to pickup the tach signal. I was thinking about the VAG tool they use to pickup the signal off the bell housing on the older ones. I just don't remember if the A4's have that??? Either way, if someone knows a positive way that doesn't require custom parts, I'd be eternaly greatful.

BTW, acording to the FAQ. My next performance option is the .184 injectors. Is anyone certain that the '02 Auto TDI's don't already have this? If so, anyone have a set lying around they want to sell cheap (OK, Cheaper?)

To my knowledge and experience with Dynos, there is no signal under the hood of an ALH engine that a Dynojet 248C can pickup with any of their (primary or secondary) sensors. That's why I build the little combination of equipment I did to capture the injection signal based on the Ferrett Injection Pulse monitor.

Haven't spent any time on a Mustang dyno but if you can calibrate RPMs to MPH, then it should pretty accurately determine the Torque.

I run on a DynoJet today. We got a tach signal using a pezio pickup on an injector line. Only made one run, but got an idea about what I have.

Hey Robbie did you ever dyno Tessa's A3 with these chips in it? I'm itching to run down to Thunder Valley sometime soon and do some runs for fun [img]/images/graemlins/smile.gif[/img]...see if I can get that 7 second 0-60 at least. I figured out why I was boiling my tires at Dzljet's...my battery was in the trunk, and I figure that 40-50 pounds taken off the top has to make a little difference with grip, think? Not to mention my refusing to let up cause I enjoyed the tire spin so much, snicker.

Your right runonbeer, I had a custom burn Upsolute installed two weeks ago. And got rid of the box.

I haven't had the A3 on the dyno, I've been tinkering with it though, its amazing what IQ does for you when you've got a fat pump to play with.

i dynoed the other day.. they were unable to get a torque reading... but i got 102.8hp on a stock 04 PD jetta [img]/images/graemlins/smile.gif[/img]

my baby made me proud... the guys said the power curve was unreal... absolutely unbelievable... cant wait to mod thehell out of her!

Stock A4/Mk4 12V VR6 dyno (for comparison):


Baseline dyno
ALH, B.184, 10mm, racepipe, custom IC and piping, 2.5" exhaust



ASV, RC3.1, B.205, 10mm, racepipe, custom IC and piping, 2.5" exhaust


Doing the math reveals:


Notes:
-values as at the wheels
-uncorrected
-elevation ~3400 feet
-baseline run in 4th, chipped dyno run in 3rd
-heavier wheels for chipped dyno run
-custom IC and piping because it's installed in a Rabbit.
