And what would an IP check accomplish? Wow... Let me see... if I do an IP check on myself, I find that I'm homed to Memphis, but I actually live in Birmingham.

 

Just for the record. The picture of the damaged pulley was not a UR Pulley. 3rd post down by Trijicon on page 4 of this thread:

Internet 101. An IP check goes back to the ISP that's being used, that in turn can pull a company name (if it is a company account), user name, and address. All public info if you have the IP address. Sort of like skip-tracing, but much easier.

 

thank you - I was wondering when someone would point that out

 

If you're talking about 1st gear and 2nd gear, then yes, torque is sustained a little longer; however, when factor in the gears that are used in 1/4 mile race or road race, you'll see that the only real advantage of the flywheel is far easier rev matching.

Here is a great article that highlights the advantages and disadvantages of a lightended flywheel (12lbs vs the 26lb dual mass stocker) on a 95 M3.

This article furthers what I've been saying all along. The lightened flywheel/pulley will make upper rpms gains in the lower gears; however, there is a loss in power in the lower rpms. Also, the reduction of inertial mass hurts off the line acceleration. Finally, the gains of the lightened components are basically nill in 3rd+ gears. If you do the calculations, you'll see that a slight gain in 1st and 2nd will do nothing for performance in the 1/4 mile because 4 gears are utilized through run and you spend most of the time accelerating in gears 3 and 4, not 1 or 2.

 

I understand the mechanics behind IP. But an IP check is worthless if his IP comes from a DHCP pool, which is likely the case. Like I said in my previous post, when I was posting from home, a reverse IP lookup suggested I was posting from Memphis, when in fact I was living in Birmingham. An IP check would not prove his identity.

 

Well technically the ISP should have logs of who was assigned a given IP address at a given time. Though getting that information from them without a warrant might be difficult (privacy and such). If you are really concerned that the guy is not who he says he is (though I see no reason for him to lie) then call UR and ask for him.

 

yeah because someone is going to take the time to impersonate the owner of Unorthodox...

Having known Shawn for 10 years now, I can personally vouch for it being him who posted

 

No one from UR is posting on here, you can rest assure from that....

Back to discussion -

I find it interesting that someone is claiming that by having a lightened flywheel there is no power gain from 1st and 2nd gear and nothing from 3rd and 4th...

Unless I'm reading it incorrectly...

I would agree that though a power gain would be nill in any gear, the mere fact that you can now spin the crank faster due to less weight on it and less resistance against it, you in return get more power faster...for what it's worth I think a lightened flywheel is always a good idea unless the crank is balanced with the flywheel on it, which is highly doubtful....

 

I agree. That's why I questioned the use of an IP check in the first place. I really didn't mean to derail this thread so far, but an IP check would be completely useless. That's all I was pointing out to gothchick.

 

you are completely, utterly, absolutely wrong

Shawn posted here because I called him yesterday and mentioned the thread - don't believe me? Call him yourself and ask him

631.586.9525

 

Moment of inertia and gear multiplication. That is why there is no measured power gain in the higher gears. There is an elaborate physics equation you can use to calculate it which takes into consideration the mass and size of the object (flywheel/pulley) and gear ratios for each gear. Apparantly this is equation and physics fact is way above Shawn's head at UR because he still preaches that the car will be faster in the 1/4 mile with his product.

 

why would I call him? I have Brian's number and if I needed to speak with anyone from U/R I would talk with the Marketing guy as we know each other...

also, somewhat abrasive don't you think, just calling out a potential customer and telling them they are..how you say...not something a little more pc like, i disagree with you.. or something along those lines? yikes, don't get all up in defense mode

 

That's interesting... I have a JWT flywheel and I certainly did notice a tenth faster consistantly at the track, but nothing to the point that I wouldn't sit here and preach it's the end of all being....

 

What's so useless about tracing a company name, user name, and address from any given IP? It's public info. The ISP WILL give it to anyone who asks. I've done it. It's nowhere near as useless as the reverse lookup Trey is pointing out. Please go back to Internet 101, Trey.

 

Have you considered that the guy might not be posting from his business? Possibly from home, or an airport, or a Starbucks hotspot? ing.

Wriiiite. I guess you're the expert. Maybe I should evaluate my career and my experience. I guess in my 11 years of professional employment I haven't learned anything.


And tell me something: how many of these so-called IP checks have you performed? How many requests to ISP's have you sent? How many have responded? Giving away IP addresses of customers without a court order, or even the threat of a court order, is a big privacy issue, and something unlikely to be done by an ISP lightly.

I think you may need to revisit Internet 101, as you call it. Domain registrations are public information, user/ip mappings are not.

 

No sorry, you won't get "PC" from me. You stated that I was lying about Shawn being the one who posted...as if you knew actually knew. Being that I do know that he was the one who posted (as if it even matters!), I felt it necessary to correct you in your incorrect assumption.

Again, I know it was he who posted because I am the one who called and spoke with Shawn yesterday, and suggested he participate in the thread. He obliged by replying to this thread yesterday afternoon.

If you, or anyone else is that overwhelmingly concerned that it somehow was someone else pretending to be Shawn, again, call him and ask him yourselves

 

Another one on lightweight pullies. My God this is a dead horse, and I can't believe Z1 got sucked into yet another argument about this.

I don't like them, and I think for sustained rpm use, like road racing your daily driver, they are stupid. There are SAE papers to buy and download if you want to see the math. However, most street driven vehicles won't see any extended wear that will come about before some other critical piece fails in the engine, and race engine's get rebuilt every weekend, or at least every season, anyways. The posts above cover my feelings in detail and every other opinion a person could have on this. I'm just amazed at how this mod maybe frees up 2-3 hp but is the most controversial thing on this forum after the Dreamwerkes supercharger.

Doesn't matter. He still has to authenticate against his ISP to get to the internet from where ever he is. ANY IP he uses will always log back to his ISP.

The only reliable way to mask an IP is by using a Proxy server to bounce around to different country's before popping back to your own locale. And those tend to be s-l-o-w as ****.

Didn't you mention you've been an IT professional for years & years? You should know this stuff then. You're not as Anonymous online as you think.

Totally not true. It's public domain. Nothing private about it. Like an "IP Phonebook" with addresses & names. Think about that next time you show your @ss online. The only thing saving you here is the Mod only has access to IPs.

Here - give me ANY valid IP that YOU used to log to the Internet (non-proxied, scrubbed, or spoofed) and I'll mail you an Internet 101 manual. And don't worry, I'm too busy with my own life to stalk someone else's. Hehehee! :-)

 

I suggest everyone read this because Resolute really knows what's he's talking about and it's always good to get a second opinion, especially when that first opinion is coming from the maker of said part.
