| Post subject: | on power problem |
hi guys, got an issue with my t3, every time i hit the throttle the rear end steps out, and hard. and once it steps out the car does a 360, i cant do anything to stop it and bring it back under control. it has absolutely zero rear grip on power... its not really a problem with my setup, but rather an odd thing that seems to happen only with my car. A friend with exactly the same gear and setup doesn't get this happening at all. it almost feels as though something bottoms out and causes it to snap really hard. the only way i can accelerate is to straighten up and then get on the power. so has anybody ever had this problem? any advice would be great. and it does this with all kinds of different setups on completely different tracks cheers ben |

Hey Ben Hows your rear diff ?? if this is too light it can cause this problem also check the driveshafts arn't catching the nut on the rear diff maybe a bearing is tight too |

diff feels like butter, definately not the problem. and a mate with the same gear in his car doesnt have this problem, so if my driveshafts were hitting i imagine his would be too, causing the same problem bearings are a month old ceramics, they feel fine.... |

Hey sidecarphil, yeah am having the same issue here on my new T3. All my other friends have enough power on the car through the corners and I spin out. Hope someone can fill us in. |

Ben I came to a decent setup today, you may want to try it, am running sweep 30's tires rubber. Plenty of rear end grip with this setup. xform/index.php?act=view&ID=1711&setup=t3 |

Hi Guys, i had the same problem on my T3. i did everything to find out what the problem was but didn't find it. it only happened on very slow corners when you acclerate, on every other parts of the track car was perfect. i finally go back but to the t2 2009. i did the euro last week. what i really think was my problem i made cyano on every hole under the chassis, and if there is a very small amount of dirt you can already get some tweak in the car. everything was straight on the car, rebuildt other things again and again, did some testing.... and the other problem from changing to lipo, modified racing with variable timing, a speedo which was set to agressive and all together made the car really hard to acclerate after slow parts. when you are using sweep tyres or xenon, the problem can be reduced or even is away but next time you put sorex tires on (which really have more steering) problem is still there. my first race was ets in warschau with both cars (T3 and T2 009), track was not easy and poor grip, modified with 2009 was very nice and in stock with my t3 it was really hard, and on every race i had the problems still i sell it. this is not a solution but i did it. but can't wait for the nice new xray. other t3 from my team mates works amazing greetings joe |

The diff was Ben's problem, it felt fine off the track but on the track you couldn't put the power down. |

Not currently a risk for me as I have a SPec-R diff with 3000 oil in it. The rip out of corners is far better. Skiddins |

hi guys, on the euro the drivers who used the spec-r diff run on 1000wt oil. the harder the oil inside the less turn-in you get. |
