G500 test car for Performance Crank Pulley

[omeyhomey]

Hey guys,

I am looking for a W463 G500 to be a tester for a performance crank pulley. The pulley has already been tested and the production model is out, therefore I would like a G-wagon member to test it out just to see how they like it and report back to the G-community. If interested let me know (via PM or this thread). Thx

I did some calculations in order to get an Idea of just how much in fuel savings the pulley would provide. Based on my calculations (estimating 3mpg increase on stock MB, $3 gas per gallon, 20 gallon tank, avg 12k mileage per year). You could save $400-500 in fuel savings alone in the first year so the pulley actually pays for itself in gas savings. Honestly 3mpg is conservative in my opinion but you get the Idea. So really theres nothing to lose. I know you G-wagon guys would love some extra mpg

There's a fair number of gear heads on this site... not to speak for them, but a little more description of the performance pulley would be great... and for the non-gear heads, what it is... and why the vehicle wouldn't consequently run lean or lose power, or shrivel up and disappear... who knows! You wont find anybody who wouldn't mind a little better economy. Where are you located?

Did i miss it...but how much is it??

I have no engineering background, but perhaps the seller should be asked:

1. Where the independant testing data supporting his claims is?

2. Whether he is supplying the 'testing' pulleys free of charge?

3. Whether he'll pay reparation in case of engine damage?

4. Why he posted the same (offer?) in the following forae:
W163M Class
W210 E55 AMG
W211 E55 AMG
W220 S Class
G - Class
W208 CLK Class
W129 SL Class

A few things,

How does the size of the tank make a difference in your calculations? It should be irrelevant.

A 3 mpg increase on a truck (G500) that on average gets 15mpg is a 20% increase! If it were as simple as a pulley swap, I think MB would have done this already. I hope you understand my skepticism, but a 20% increase in economy is HUGE, and I would need to see empirical data supporting this before buying into it..

Good luck with your endeavor.

The reason MB does not do it is b/c it is prohibitively expensive, and you could make that arguement with any part of the car like intake, exhaust and everything else. At the end of the day they need to make $$ and they always leave that extra envelope for the consumer to take the car to the next level, great question though.

MSRP is $549, but special introductory offer is $499 for a limited time. Not bad considering most MB crank pulleys are $900-2000 .

Hello Leon,

Size of the tank DOES make a difference because the smaller it is the more it has to be refilled per year hence more $$ spent which is why it was included in the calculations. I tried to get an avg MB gas tank size + avg fuel mileage (some AMGs are much lower but roughly 15 is about avg for in city driving). 20% is not that much, you can get same results from intake & exhaust. Anything to improve engine efficiency increases gas mileage (with the exception of fuel mods like injectors, they directly decrease mpg).

if you don't believe me heres proof....

(15 mile avg, steady rpm @ 70mph, level ground)
Mods at time: K&N, Royal purple in drivetrain, X-pipe & AMS CP.

There's a flaw in your logic WRT tank size. If one drives 12,000 miles per year as you state. It makes no difference if one has a 10 gallon tank or 50 gallon tank, one will use the same amount of fuel to drive those 12,000 miles. The number of stops to refuel is different, that's all.


I'm not sure what that photo is supposed to prove.. What car is that display from? What was the mpg prior to the pulley install; assuming the car has a pulley installed.

Also, if you have the proof, then why do you need a donor car?

Peace,
Leon
