Default Got boost?

<center><img src="http://img.photobucket.com/albums/v663/jeanvang7/Maha_1.jpg"></center><p>Hi Everyone,

We are having a special on our Stage 1 chip this month for $495.00 with free AFE drop in filter and shipping. The chip was tested in house on our MAHA dyno on a 2004 B6 A4 Ultra Sport and put down a honest 195hp and 227 lb/ft to the crank. Don't be fooled by other dyno numbers or excel graphs, had this been done on a Dynojet or Mustang dyno,
the numbers would have been significantly higher.

Default I may be wrong but how can you get "Honest" chp number on a wheel dyno?

It is impossible to get "Honest" CHP or CTQ numbers from a wheeled dyno, best you can do is estimate. If you are using an up conversion factor (multiplier) then you are meerely estimating the CHP regardless of how optomistic or pessimistic your figure or dyno may be.

Default well the idea/design of the Maha dyno is to measure drive train loss during roll-down back to idle

after a pull. So it's an approximation but it's more accurate than %loss concept. The green line represents the measured drag on the rollers/dyno during the coast down (clutch disengaged).

Default For those who question the accuracy of the AMS MAHA...

<a href="http://www.advancedmotorsport.com/maha/R32_STOCK.pdf">Stock R32 Dyno Run.</a>

<a href="http://www.advancedmotorsport.com/maha/WRX_STI.pdf">Stock WRX STI Dyno Run.</a>

We have also seen that more than 95% of the European companies use the MAHA as a benchmark for the power tests.

The Calculation of the MAHA vs. other Dynamometers

Taken from our website:

The second type of dyno is a chassis dyno, which merely requires driving the vehicle onto the rollers and strapping the vehicle down, so it doesn't run off the dyno, and then measuring the amount of resistance/work it can overcome.

There are 2 main obstacles when using a chassis dyno, the first is airflow. Most fans used on chassis dynamometers are taken from
contractor suppliers and struggle to simulate a 10-20 MPH road speed, which is equivalent to your doctor asking you to submit to a fitness test while in a sauna. Needless to say, your score will be low. The MAHA approved custom built,"AIR 8" fan on the AMS MAHA dyno, flows over 80,000 CFM (cubic feet/minute) or a road speed of 60-70 MPH!

The second obstacle, is that most dyno's only measure "wheel horsepower" - that is the power that isn't sapped away by everything
located after the clutch (transmission, differentials, driveshaft, axles, even the wheels and tires themselves!). And since wheel
horsepower readings are dependent on the temperature of your transmission and differential oils (cold oil is like molasses and warm is like water..warm oil eats less power) and tire temperature (cold tires offer less resistance than warm sticky tires) so driveline loss can be inconsistant or as an expert refered to it as a moving target !

Many people simply add back a "guesstimate" of the parasitic drag of these components anywhere from 10-20% for FWD or RWD cars and 25-40% for AWD or 4WD cars. The final numbers are only as accurate as the tuner's best guess.

AMS and many OE manufactures have felt that was an unacceptable platform to tune a vehicle from and went in search of something more precise and reliable.

The result of our search was the MAHA LPS 3000.
The inherent beauty of a dyno system like the MAHA LPS 3000, is that after it has measured the wheel horsepower, it measures the resistance of the entire drive train from the clutch to the tires So instead of dynoing a vehicle with a reported 200HP and measuring only 150HP at the wheel, and ASSUMING that 50HP was eaten up by the drag of the drivetrain and wheels The LPS 3000 actually measures the drag loss during the coast down phase. In fact, if the drag loss is only 30 HP, you know beyond a "guesstimate" that your engine only made 180HP, or if the drag was 50HP, you will know EXACTLY how much power your vehicle is really making. However, with a drag measurement you can rest assured that you have isolated ONLY the Engine's HP and not the engine's power minus an unknown amount of drag. The system also corrects for enviromental conditions.

Thus far every stock production car that AMS has tested from Audi, VW and Porsche has dyno'ed within 0-5 HP of the factory crank Horsepower claim. It's that accurate!

We invite all European car enthusiasts to visit our facility and make use of this amazingly accurate tool to make your vehicle the best it can be!
