Ralliart Flywheel and LSD!!!!!!!
JAJAJAJAJJAJAJAJ!!!!!!
lol
me disen ke ahy 2 o 3 en la fiebre dando duro, ESO ME DISEN, yo nose, jeje

People say in mayaguez are 2 or 3 RA kicking every one but's...
DAMN my english SUCK!!
, hahahaha

OK guys from this post on, im going to change the topic,
I JUST DONT WANT TO MAKE A NEW TOPIC CAUSE MODERATORS SAY I DONT SEARCH AND THING LIKE THAT, SO IM GOING TO TRY TO USE THIS ONE, I DON THINK THIS WILL WORK HEHE
What are your opinions on phantom grip???
people say it will it the differential and all that, but do you think I will have problems with it??
Also I know Quaife make an LSD, and RRM are selling it, BUT its too expensive for what i want to spend
thanks

If I had the choice between flywheel or LSD being turbo, for sure get LSD!!! I have to baby 1st & 2nd waaaay to much, especially coming out of a corner. Flywheel is good for quick spurts of acceleration and dare I say str33t r@cing, but not for 1/4 mile due to lack of momentum from a heavier flywheel keeping the rpm's from dropping so quick and staying in the ideal boost range.
OK, to continue this :
"NOT GAINS in HP and loose in TQ with a FLYWHEEL" converted topic, hehehe, still have no answer for the original topic, but anyway
This Is what RRM says about their UDPulley:
RALLIART MIVEC ENGINE UNDERDRIVE PULLEY KIT
This pulley kit yielded an improvement of around 6-7whp and around 9ft/lbs of torque. Both the lighter construction and smaller size helps improve power. Comes with belt and pulley. That is all you need. See below for details.
Correct me if im wrong, but it is the UD Pulley does exactly the same as the Flywheel, and this is taking off weight of the engine so it can move easier
So why does the UD Pulley give you whp/tq, and by what you all say, the flywheel not??
Explain because its the SAAAAMEEE!

The modification itself doesn't "give" you hp.
I mean, a CAI will give you more hp because there is "an increase in the diameter of the air intake, allowing increased airflow, hence more power."
A pulley on the other hand doesn't provide you with more hp. There is nothing about it that governs a way of producing more hp. It just frees up hp. The rotational mass of the pulley is by far much more responsive because the "the underdriven/lighter pulley is .58lbs and the stock unit is 3.911lbs. This is nearly 85% lighter."
Thats what I believe RRM means when they say there is an "improvement of around 6-7whp".

I will copy and paste an IM conversation I had with another member the other day explaining all this when I get home, I'm not typing it all over again. Check back later tonight!
Both the UDP and the Flywheel, FREE UP horsepower that was wasted in rotating the flywheel/Pulley.
I have both items and the only thing I regret is that my tranny's synchros are broken. The acceleration is downright silly. I havent dynoed yet for the flywheel, but with Injen CAI, old downpipe, stock exhaust and pulley I dynoed 171 hp and 166 tq. Give around 5 more for the wheel(being REALLY modest here).

It appears I have lost that conversation. I'm not really an IM kinda guy
Summary:
The pulley is a large portion of the mass of the drivebelt system, not to mention the smaller diameter which both decreases it's rotational mass and allows the pulley to do less work on the drivebelt system. That is alot of HP to gain, and there is nothing you can do to add load on the system except run the A/C.
The flywheel, on the other hand, does not decrease in diameter. inertia is partially dependant on diameter, which is +1 to the pulley. The weight decrease is great, if you want crank HP increases. With the clutch in the flywheel is 100% of the drivetrain weight, and the decrease in weight with the lightweight flywheel is a great difference. However, when the flywheel is connected to the rest of the drivetrain through the clutch it is a much smaller proportion of the mass of the system.
All of this contributes to the fact that while the flywheel will gain you BHP, your net WHP will be negligible.
Forgive me if I am mistaken, it has happened before.

The outcome is that the car will accelerate quicker, but the force you feel when you shift a great shift, will diminish somehow, the only gear when this is noticeable is second, the crappiest gear of them all. The only thing is that you have to know how to shift GREAT to really harness its power
ok man. the flywheel is connected to the engine, not transmission, so when you are shifting the shifter between gears it is not affecting you at all. you won't gain WHP.(negligible as I said before) I have been over the eddy current vs. inertia dyno argument before so I won't start it again, but look at the comment I have quoted below. In the event you where to test this on an eddy current dyno your net gain would be negligible. Come up with some proof man, or take my research and knowledge and learn from it. Anyone can seen removing weight will make your car go faster, I am just trying to get you to realize your explanation is wrong.regarding VERY light flywheels in some pretty fast vettes from vetteweb.com. you will be interested to know that in a 400RWHP car the gain was only around 12HP and 20TQ, that doesn't translate to much in a 140FWHP car, especially on an inertia dyno.
At the conclusion of the tests, Reese shared his observations with us about installing the Fidanza and SPEC components into our test cars. "The important thing to look at in this test procedure is the time to speed relationship, not necessarily the increase in horsepower. Keep in mind the test device we used was an inertia dyno. A flywheel does not make any horsepower, but it shows up as a horsepower gain because you have reduced the inertia on an inertia dyno. So you need to look at the reduction in time to speed that was created by the reduction of inertia. We went from 14 to 11 seconds to 145 mph on the stock Z06. What that tells you is how the car is going to feel on the street. It is going to accelerate quicker to the redline."
I can't be any clearer than that, someone else's turn.
