Agreed, I’m not sure who could argue against that. Having said that, I’m not too worried about the accessories and have the JHM pulley…
Now not to be defending issam, but I understood that he meant 1.) any 3.0T, including the 8 speed tip, and 2.) the 20-25 hp was coming from the pulley overdrive. Maybe wasn’t clear to everyone.
How the rest of AZ understands it? Who gives a crap. I bought the JHM pulley and don’t care what anyone else does. Why are you guys always worried about convincing the world? Let them buy it, realize later they paid more/waited for something that was unnecessary, and learn to be more inquisitive in the future. That’s a better lesson than what they learn arguing on the internet.
The way I read it is he thinks the pulley will make 20-25whp over any other solid pulley, not an OEM diameter vs an overdrive.
Also why are we talking about tractor engines and engines from the 1900s. These are German built internally balanced engines that run a million times smoother than anything that truly needs an external engine damper. IMHO without some ridiculous piece of test equipment to show the difference between dampened pulley and a solid pulley, the average person won’t feel a thing and the performance gain is either non existent and pointless or performance is possibly lost due to increased weight.
The argument does get ridiculous, but some people that are just reading listen and save their money, plus it always feels good to come back and say “we told you so.” I also don’t agree with the snake salesman making a dime off these idiots especially when he isn’t a vendor and the damn product doesn’t exist!
The driver or passengers don’t feel it ever. The vibration only is in the crankshaft. It was a little damper history sorry couldn’t help it. When a crankshaft is balanced it taking care of harmonic resonance. You will still have torsional vibrations no matter what It is just how piston engines work
I don’t care really, just wanted to put out there the facts about torsional dampers. The JHM pulley is a nice piece for sure, and if want more boost from my stage 2 I would go that route.
I think you misunderstood, and are as a result perpetuating the bullshit.
He was claiming that equal sized solid billet pulley vs. fluidampr would be a difference of 20-25 whp. Hence the uproar.
His biggest example was a VR6 car that made something like 30whp on the dyno with fluidampr. Explain that if you really think he’s talking diameter resulting in supercharger RPMs. There is no supercharger.
As for why worry about what other people are doing, that’s why there are forums. Otherwise we’d just sit at home and talk to ourselves.
Here’s his post from the thread about the JHM pulley (billet, OD)
[quote=Issam@INAdreaming]This is the MK5 R32 turbo crowd and history will repeat itself so I am going to call a prediction from now.
Audi B8 S4 with either a 7 speed DSG or 8 speed automatic going from a billet pulley with 0 torsional vibration reduction capabilities to a Fluidampr will see a 20-25whp gain on the dyno under the same conditions.

Here are his followup posts after people laughed at him
[quote]The claim I made was based on past experience with DSG gearboxes + Dual Mass flywheels and users going from rubber/billet aluminum dampers to Fluidamprs

Since you’re being a bit of an INA apologist and will probably try to ‘Making a Murderer’ those quotes into possibly meaning something else, this should be the final nail in the coffin…
your post made tons of sense, and I don’t think Euroswagr was having a go at you specifically…he’s pointing out that people are focusing on these great softening benefits of a fluidampr, however those benefits only exist on big, diesel, cammy, heavy engines. On a $60,000 german sports sedan it’s a non-factor.
Definitely wasn’t a shot at your comment littleredwagon, it was more of a shot at the idiots on AZ supporting the moron pushing the product without any factual information.
I think you understood most of what I said…but just to clarify
-The Fluidamper won’t be noticed from a comfort standpoint…so no advantage there
-It will not provide an increase in power, especially 25whp over a solid damper with the same sizing
-If it is heavier AND the same size as JHM or the OEM part, it may in fact HURT performance
-Torsional vibrations are minimal to begin with, even if the part reduces those vibrations, what is the advantage? The only thing they can show is a graph from a piece of measuring equipment. No long-term testing or a breakdown of a motor with 100k mile on it to see if the damper protected against bearing fatigue or a similar
We define items like this as 'snake oil" for a reason.
I completely agree that when dampers were introduced in the 1900s they made a huge difference and were a great advancement for internal combustion engines…this company is far from inventing the next big thing.
This is all true, especially the last part, they only way to quantify the results would be to pull a motor apart with high mileage on an un-dampened pulley and see it compared to standard bearing wear. Besides the fluid style dampers from what I saw are unnecessary on an engine of this size and the RPM where it operates. IF you wanted one you are better off with the rubber style anyway. Of course that is once source and I am far from an Engine Builder, more like just an assembler
