  1. Glad you all enjoyed it
  2. Adobe premier elements.
  3. haha, oh yeah. Was just a rush job though. Not a massive amount of thought went into it.
  4. I was bored so I made this http://media.putfile.com/mcrae-gathering-hype-vid Enjoy!!
  5. 1 Yogi 2.tank 3.Pistonbroke2 4. 5. There must be more than the 3 of us turning up?!?
  6. Is your brake fluid turning black? if so, its time to change
  7. I would never take the scoob to one, but the 'Mr Clutch' places are very very cheap.
  8. Get a video on here of it mate, I might get one
  9. I'd love to do this, my misses hates camping though
  10. Lol, so, did you pick it up then?
  11. Lol, I've actually done that before on a mondeo subframe bolt. Took an age to get the thing out too. Have they welded in a new bolt and closed the hole? You were lucky with your flywheel, I've heard that if they shatter while doing high RPM, not a lot can stop the bits as they fly apart, I've read that they can smash through the bell housing, through the transmission tunnel and into the cabin of the car, closely followed by the drivers legs
  12. Pain in the ass?, I thought you said it took "them" 7 hours to do. Or did you do the work yourself?
  13. Unlucky, or lucky. Depending on which way you look at it. You were less than 5mph away from a ban
  14. Welcome to the fray, Ill be seeing you around as I'm just down the road from you.
  15. Ok, I submit, seeing as you have first hand experience and you actually own a lightened flywheel. My argument is negated
  16. Asking google the question about engine braking effect shows a pretty clear answer that it seems to increase engine braking . http://www.google.co.uk/search?hl=en&q...aking&meta= EDIT- it seems it depends on what actual engine braking effect we are addressing. Riding the gear using the engine to slow you down will have a greater effect. But, coasting with the clutch in then engaging the gear will not initially slow the car down due to the fact the flywheel can spin up easier. Once engaged however, the engine will in fact slow the car quicker than it would if it were to have the heavier flywheel.
  17. I've been scouring the net for a definitive answer on this. I'm still pretty sure a lightweight flywheel causes GREATER engine braking effect due to LESS rotational momentum carried from the flywheel (which effectivly is storage for forward momentum) and came across this. Flywheel Upgrades How does a lightweight flywheel improve performance? A transmission can be thought of as a fulcrum and lever in a car. First gear has a really long lever; second gear has a shorter lever, etc. The lever represents the mechanical advantage that gears give your vehicle. When your car is moving, you have two factors that are present during acceleration, one is driveline losses, which are constant and the variable, which is vehicle weight and the mechanical advantage supplied by each gear. While changing to a lighter flywheel will give the user little to no changes on a dyno, the apparent changes are quite dramatic due to the greater mechanical advantage. Consider these made up figures for consideration: Drive line losses, 45 pounds and vehicle mass (weight) at the driveline (remember your gear's mechanical advantage reduces your actual car weight). We know that within reason, vehicle mass is a constant. Now imagine if you reduced the driveline loss from 45 to 35 with the use of a lightweight flywheel. Since the engine has less drivetrain losses to compensate for, this means the "gained" horsepower can be applied to moving the vehicle mass. Using mathematics, one can realize that the higher you go up in gears, the less effect that a lightened flywheel will have to the overall equation. How much will a lightweight flywheel affect my car's performance? This Excel document will allow you to find out for your WRX or STi application. Are there any downsides to a lightweight flywheel? While the performance characteristics of a lightweight flywheel seem to be the perfect solution, there are compromises: a. Low end performance is affected. This usually means that higher revs are necessary for smooth starts due to the reduced rotational mass. For drag racers, this can be a BIG issue. b. Missfire check engine lights on the WRX. What causes a missfire CEL with lightweight flywheels? No one is really sure. There are theories though. One theory is that the Crank Position Sensor senses the rotational speed of your crankshaft. Since a lightweight flywheel reduces the rotation mass of your engine, your crankshaft accelerates and decelerates quicker than OEM specifications. Another theory is that there is a missmatch of information from your Crank Position Sensor and the Cam Position Sensor during acceleration and deceleration. This may or may not be caused by the slow reaction of the belt tensioner which will cause enough belt slop to give erroneous readings to the ECU. Since missfire CELs (due to lightweight flywheels) do not occur on the STi and the STi has two Cam Position Sensors, this adds further evidence that the missfire CEL has something to do with the Cam Position Sensor since there is only one on the WRX. Which lightweight flywheel will not throw a missfire CEL? In truth, there is no lightweight flywheel that will not throw a missfire CEL. The odds of you throwing a missfire CEL are higher the lower in flywheel weight you go. Even with a “heavier” lightweight flywheel, you may throw a missfire CEL. To date though, STi owners can use lightweight flywheels of any weight without throwing a missfire CEL. Will the use of a lightweight pulley increase my chances of a missfire CEL with a lightweight flywheel? Yes. To a smaller degree, lightweight pulleys also decrease rotation mass, adding their quicker acceleration and deceleration into the equation. How do I fix a missfire CEL with a lightweight flywheel? The safest course of action is to use a portable OBDII code instrument and clear the codes frequently. Once you know the frequency of the missfire CELs, it will aid you in determining if this is an actual code or perhaps something to investigate further. While the missfire CEL code is a "safe code" (just an indicator and won't throw your car into safe or limp mode), it is never a good idea to drive around with the CEL on for extended periods of time as another, more serious code can be present without your knowledge. Additionally, it is not a wise idea to remove the missfire CELs via engine management software. Missfire codes can be an indication of a problem and removing their presence will remove possible symptoms of an actual problem. Who is a good or a bad candidate for a lightweight flywheel? Arguably, the users whose driving technique is most highlighted by the benefits of a lightweight flywheel are people who autocross frequently. Many people are also genuinely happy with the performance increase in their daily driven vehicles as well. The only group that is generally dissatisfied are people who competitively drag race as the reduced rotational mass does not lend itself to their severe launch techniques.

  18. Are you sure about that Granby,? I thought Lightweight flywheels make the car lumpier due to the less rotational mass in the flywheel. You also get more pronounced engine braking with lighter flywheels due again to the lack of weight in the flywheel carrying the momentum of the engine.
  19. Sorry to see this, I really can't understand the mentality of these idiots. Be careful with T-cut, especially if you have metallic paint. Solid paints are fine with T-cut but you need specific metallic T-cut for metallic paint. If you use standard T-cut on metallic paint you'll mess it up.
  20. These need to sell as they are taking up too much space, open to offers.
  21. Make me an offer mate and you might bag yourself a really good deal !
  22. Lol, reminds me of the Ka adds
