(10-25-2010, 03:42 PM)Captain America Ok so I just got done talking with Pete @ WOT. We are go for a dyno day if you guys want to do another. He's got the optical sensor to get the RPM signal. He said that setting up the optical takes a bit of time so sometimes its easeir to set the engine RPM in the dyno computer based on roll speed which he said works out well. It would be $50 a car for 3 runs. He said with his schedualling a sunday would work out better (didn't think that would be an issue ). Also said that the gas Benz's with traction control can be tricky because the computer trips out when the front wheels are not turning, I dunno if this is a known problem or not... anyway, if we wanna come up with a date we are good to go. I would definitely be there with my POS so that would count as one.

Where are we with this? Let's do another dyno day at your buddy's shop! I have a new ignition controller I want to test thanks to GSXR, and you guys need to try this guy's Mustang dyno because of what I just read in Hot Rod: "Types of chassis dynos
Dynos can be categorized as either inertia, hydraulic, or electric. An inertia dyno can only do full-throttle acceleration runs, but the best load-bearing hydraulic and electric dynos can do step tests, constant-speed pulls, and even part-throttle testing so that full road-load simulations can be conducted right on the dyno."

"Inertia Dyno: These extrapolate rear-wheel power output by analyzing the dyno drum's acceleration rate using a sophisticated accelerometer and computer software. A vehicle is placed on the dyno with its drive wheels sitting on heavy roller drums of known mass. The car is placed in gear and accelerated at wide-open throttle. It takes a certain amount of time and force for the tires to accelerate the rollers. The acceleration rate is directly proportional to how much power the tires place on the heavy roller to get it to rotate. Inertia dynos have the reputation for reading "high." Generally, with mainstream vehicles in the 3,500-pound class, they'll yield consistent results with minimal setup time. They may have trouble obtaining accurate results with extremely heavy or light vehicles. Turbocharged engines won't build boost as they do in the real world. Dynojet is the most common pure-inertia dyno (some of its newest models have an eddy-current option)." (The whole article is here: http://www.hotrod.com/techarticles/gener...index.html

What this means is that all of you with turbos may not have gotten accurate info at our last dyno day cause that place only has a regular Dynojet. We need to go have a dyno day at Captain's buddy's place cause he has a Mustang dyno!

Totally off topic but this isn't worth starting a new thread over: Whoever that was at the 60/215/91 interchange tonight (I hope that wasn't you Captain), you didn't need to turn our little brawl into a full fledged road rage incident. My 400E is a 93, the last year without a cabin filter. I was just simply trying to get around you so I could prevent subjecting my wife and 2 kids to your prodigious diesel fumes. I also had a new air compressor in the trunk along with three tires with rims, and loads of groceries and other stuff. The car was packed solid but we still spanked you anyways. That area is heavily patroled by the revenuers (ask me how I know), so in the future, chill. If I didn't have the wife and kids with me I maybe wouldn't have minded, but you took it too far. No hard feelings, but please try to chill a bit. Getting laid might do you some good. Try it.
Regards, Eric

Haha, Eric. Wasn't me buddy... I don't have a diesel that runs at the moment. But I might this weekend! What car was it that fumigated you? I'm sure we can track him down...

The Dyno is still open for a day, whenever we choose. He is having a car show @ Norco High school on the 19th. I will be there...
