I found that a late turn in helped. Brake off a good bit of speed. Chuck the car in aggressively with a bit of trail braking and then power out. Easier said than done though as the LSD pushes the car outwards into understeer. |

I was in the same boat as ye, with the LSD exagerating the problem. A late and aggressive turn-in, and hitting the throttle a smidge before turn-in got the car pointing in the right direction quickly. This required a bit of experimenting though, as my first try resulted in a 270° rotation with pike and infield ballet. And to clarify, there was no-one within mirror sight when I was trying this. Also, I'm not looking to propagate the banter earlier in the thread at all but feel compelled to comment on what I read(and get Topaz to put more flange up ).... if I am comfortable with the other driver, I have no problem driving in close proximity with them at a committed pace. Eamo, Ludo, IanH, B318isP, Ger, the lad in the gorgeous white E46 M3 stand out to me as they are people I can keep with, and who are compenant courteous drivers who respect the ability of those around them who share track experience and are close on track speed. Essentially I am expanding on what I interperet Eamos comment on 'dicing' to mean, and how I don't think, in the context of how I have seen Eamo drive, it is dangerous per sé, even though he spun off. There are many other who don't go as quick as me around there, either due to limitations in car, experience, or by choice at the time. And sometimes passing can be more dicey that driving at a committed pace with those you know and love . the biggest scare I had was last April with a car I had never met out there before and was passing. Ludo got a bigger fright behind me as he was following me through. That was the only real incident I've ever had on a track and I've driven close with people and other than that I've always seen good driving by slower drivers out there. In fairness to Eamo, I've always admired his car control and ability to go from úber-pace to trundling as track conditions have dictated, where others including myself have tried to push through. And Ger gave me tuition on my 2nd ever track session that knocked 6 sec off my wet pace and had me lapping as quick as race Puntos in the dry by the end of the session. Both of ye I have enormous respect for out on the track and off, and my comments here are not a cloaked effort to admonish either of you. roll on Sunday! |

At the time he told me that he was watching a car coming up behind him at Dunlop and missed his braking point! |

My inexperience is one of the reasons I would be happy for Killian and
Eamo to come with me as a passenger for my first few laps. Nothing
takes away from their experience on the track and my lack of. I know my
limitations and I am going to be paintent as to learn and get the most
out of those 400 horses I will be riding.
Can't wait, too bad I don't get to hear my car from the outside. The 840ci will be loud as well, there is no replacement for displacement. |

I hardly used 2nd all day! 3rd and 4th was all I needed. Drove smoother and reduced my overbraking. |

@ Topaz: I hear ya! The BMWclub could become the TTclub (and I'm not talkin' Audis...) @ GStan: my Godsons 2nd birthday party is on Saturday, so I'm heading up Sat morn. I'll miss the convoy, but get a bit of sleep Sun morn! Serious convoy alright though.. mighty stuff. @ KBannon & B318isp:my yoke hits the ton in 3rd, but this time I think I'll short shift to 4th @ 85mph, as this drops revs to 4,000ish which is around peak torque and it seems to pull to 100 as quick as 3rd does, aswell as being easier on engine. |

@ T.J. are you around later? Better settle up for that limo oil with ya... Can make Carrigaline for arounds half 6 if that suits you? Don't think i broke the 100mph mark at all the last day in Mondello, just about broke 95. @B318isp: Did you brake the 100mph mark the last time in Mondello in the 318is? |

Call away - I'll be in & around Carrigaline all evening, and the oil is in the back of the car, so call when ever suits.

@ Ludo - I agree, and have always changed on the red. But a bit of scientific messing about seems to show that the speed increase in 3rd is similar if not a tad slower than in 4th from 85-90mph on (ie 5,500rpm), so 100mph is a bit of a slog in 3rd. On Sunday I'm going to see if I carry any extra mph short-shifting on the 3rd to 4th change. I've the OEM induction system & throttle body which I reckon is causing it. It rips up increasingly quickly to 5,500 and then assumes a linear rate to the limiter past that.

Nah. Might see close to an indicated 155kph (probably nearer a true 90mph) before tarzan but just don't have the power to get those kind of speeds. |

Thank god for that... Was pushing hard the last time and the best i got was just over 95mph. Was getting worried there, thought i was way down on power or taking moronic lines........ See you in Mondello B318isp Graham |

Ultimately, the exit speed from Lola is the main factor as it is a simple up-the-gears run down to tarzan. Being initially uphill doesn't help either. You can't be certain of the speed you hit as braking for tarzan suddenly takes priority ! Edited by b318isp |

2 reasons for short shifting (changing before max revs) 1 To avoid having to change up in the middle of a bend. This sometimes needs to be done before Stena Line (BOAC) 2 In higher gears (3rd, 4th) the power band drop off before max revs means the short shift may be worth it especially if there is an uphill stretch (end of main straight, exit of parabolica(Lola)) to get on the rising torque curve. Watch Stena Line if it is wet. If you get on the kerbs at the exit you can end up in the bank. Same applies but not as bad to the exit of Turn 7B (Tarzan 2) Edited by gjoconnor92 |

I'd still reckon that most petrol BMWs will have more torque at higher revs in a lower gear though... ...oh, your last point reminds me of a third reason to short shift: 3. To reduce wheelspin on exit from a corner! Edited by b318isp |
