it dosnt necisarily increase HP... it just frees up HP that is being "eaten up" in those places. The pulley's lighten the routantional mass of the pulley wheels, and the same with the flywheel.
More difference will probable be felt with a flywheeel, what a lightened flywheel will do is allow your engine to rev quicker allowing for quicker accleration. |

I've heard some people have had problems with their a/c and power steering...just something to keep in mind.
Flywheel will make ur RPM's faster, cool. This post has been edited by Supersprynt: Feb 21, 2004 - 7:19 PM -------------------- |

also wouldn't it help reduce the amount of stress put on the motor from higher revs and forced induction?

ASP makes them, unorthodox does not... they're a lot cheaper than Unorthodox... -------------------- "It's ok to be naked girl... I'm an artist!"

Pulleys make waste of the stock harmonic balancer, which balances your gears together to make sure they don't damage the crank. The aftermarket gears can potentially do harm to your crank, and thus I would not recommend them to you, especially due to their limited power gains.
However, they do work on the same concept as lightening a flywheel. and that concept is lightening rotational mass. Any time you lighten rotational mass, or the mass of things that rotate (duh!), it does a LOT of good for you car. A flywheel that's 10 lbs lighter than your stock flywheel allows your revs to fall faster due to its lower inertia. The lightened rotational mass means less stress on your engine to get that flywheel moving, which means more power to the ground, faster. Note: not more power created, just more already available power transferred more efficiently. Lightening wheels will make the same type of effect. You will get better gas mileage due to less work needed to turn the wheels around, your car will be faster than if you were to take of the same weight in frictional mass (like removing your AC or jack), you benefit in handling, and you benefit in braking. Cliff notes: Lightening rotational mass = GOOD! Ridding yourself of harmonic balancer = BAD! This post has been edited by MoralWarfare: Feb 22, 2004 - 3:41 AM --------------------  |

Most cars don't have a harmonic balancer that would be affected if you took off the underdrive pulley and put an aftermarket one on. You may want to check this page out... http://www.greghome.com/Greg's%20Garag...ve%20Pulley.htm |

I agree an underdrive pulley could theoretically be a problem. but a lot of people on this site, including myself, have the ur or asp pulley with no problems.

So u guys think the flywheel of Unorthadox is a good deal for our car, it costs about $400+ .

Honestly, in our cars...it won't be a problem. With such low power in the first place, the crankshaft should hold up. Also, the problem with our engines is in the top end not the bottom end. Our bottom ends are very strong and rigid...it's the top ends and sometimes the blocks that go in our engines...at least from my experience as well as from stories on the site.
I guess though, it wouldn't necessarily be worth the money to buy an underdrive pulley considering how much power you will actually restore...but I guess the same would go for an intake and exhaust on our cars. It's all about freeing up lost power, and every little bit helps. The flywheel, however, is an awesome modification for our cars especially as you add more and more aftermarket parts. As you increase power, you still are only getting a fraction of the potential power to the ground because you are on stock drivetrain components...but as soon as you upgrade your drivetrain then you will begin to realize how much gain you are actually getting out of those mods you've spent so much money on. Honestly, the best modfication I have done to my car is my custom torque converter followed by the S-AFC. I guess the best reason why is that you get immediate satisfaction out of drivetrain upgrades because the effect is very noticeable. Sorry I'm rambling, but I just got back from a SoCo party.

I personally say the UD pulley is a very nice mod to do. IMO, it's a lot better than things like short ram intakes, and exhausts. The lighter rotational mass will also let the engine rev slightly faster, and more freely. it's worth every penny, IMO.

ditto. probably the best mod for the money. an asp pulley can be had for about 100 shipped. |

i would probably not choose the UD flywheel as my first choice on flywheels. look around at the other flywheels offered, there are alot!

thanks for the links and info. I perosnally wouldn't risk damaging my crank, even if it supposedly wouldn't do it harm,just because the gains are so minimal. But, at least now I'm smarter!

ive only heard of the fidanza and the clutch masters, any opinion on either of those? they seem to be the most popular. any notable difference between the two? |

So can u list some websites that sell the pully for our car!!, PLZ By the way, do 90-95 Toyota MR-2 and Toyota Corolla GTS with 5SFE engine (normally aspirated) can also fit for our 5S-FE Celica GT?? This post has been edited by ST-204: Feb 23, 2004 - 3:12 AM |

The Corolla GTS came with the 4AGE. The SW MR2's and the Camry UD pulleys and flywheels should all be the same... so they will fit. The Corolla's won't fit the GT, but I'm about 90% positive the Corolla GTS 4AGE flywheels do fit the Celica ST's (not the pulley; slightly different locations). You'd probably need to change the clutch to match, but it should all bolt-up. -------------------- "It's ok to be naked girl... I'm an artist!"

So except UD's pulley, what u guys recommend??
By the way, in the flywheel, UD and Fidanza, which one is better?? In price, Fidanza is cheaper than former a little bit!! |

Yeah, the rumors about damage to the crank has scared me from getting an underdrive pulley. Even though I am almost sure they are false due to the numerous websites with proof that disprove the rumors, its better to be safe than sorry just for 5-6 horsepower, 7-10 torque (according to the dynos on UR's website of similar cars). |

I just got a Zex Flywheel put in my GT and yeh you can tell the differance immediatly. its just like BOOM I had to change my whole timing pattern for my shifting. I like it alot better now.

For my swap I wanted to get the HKS Flywheel, but it would have taken 3 or more weeks to get here. So I went with clutchmaster.
One of the cool things about aluminum flywheels is they come with a steel insert, every time you get a new clutch you just replace the insert instead of refinishing your flywheel. Aluminum Flywheels are made by clutchmaster, fidanza, and UD. Basically a flywheel is a flywheel! If it comes in blue or purple or whatever it dosnt matter because it is a non visible part! |

I have a Findanza flywheel in my '95 ST. It came in just above 1/2 of what the stock flywheel weighed. Definitely made a difference in how quickly the car revs and drives. It's been installed since January 2001, about 35,000 miles with no complaints at all.
Got the flywheel from Cyberauto. |

I'm not sure how much it'd cost you to have the flywheel replaced. I pulled my own engine/tranny when I installed the clutch, as I also needed to replace my timing belt. (Engine's quite easy to work on outside the car, heh) Sorry I couldn't be more helpful. |

a flywheel should only be installed with a new clutch, not mid clutch. so they already have to take out the tranny for this, its a matter of a few bolts at that point.
