Ever since I fitted the race battery the car has struggled to start. Obviously this is kind of expected with a smaller battery but it does a really slow first rotation, then suddenly kicks in.We were thinking it could be the starter motor on its way out? ________________________________________ Rallye Race Car |

We've never had to use the jump pack as it has always started, just sometimes after 2 rotations.Battery is behind passenger seat so approx 1.5m. of 170A ________________________________________ Rallye Race Car |

This doesn't rule it out but the HG itself doesn't cause slow turning over on the starter motor does it? ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

It's only done it since we changed the battery, before then it was absolutely fine so I don't think it's HG. Plus there's absolutely no mayo in the cap (although I know that isn't conclusive).________________________________________ Rallye Race Car |

Mine cranks a bit slowly too on a race battery. Never bothered me though as it will always start, i like the fact it takes a second or two of cranking before it fires as it gives the oil pump half a chance to get some oil round the engine, that may just be my backwards logic though.  ________________________________________ Goldie the track car. |

Castor_Troy wrote: Can do water doesnt compress Really? It's normally a small seepage that stays in there as condensation isn't it? If the cyclinder was physically full of water the HG wouldn't just be not sealing it'd be not there! Surely there'd be other symptoms before that stage? I'm not saiyng you're wrong I'm just asking? ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |

This sounds like a case of maybe bad earths, if the head gasket was bad enough to half fill cylinders with water you'd have other symptoms while it's running. I'd start by cleaning all the earths and go from there! ________________________________________ Team Running Engine again!Team Negative Camber! My Budget track engine build thread!

I'll have a look at the earths. When we moved the battery we connected back up to the original earth by running a cable back, I wonder if the connection is not that great ________________________________________ Rallye Race Car |

A new starter motor will help. I replaced mine recently, was 14 years old and covered 174k. The improvement was noticeable. It turns over a hell of a lot quicker and sounds healthier when cranking over compared to the old starter motor.________________________________________ Team Peugeot Sport 308 Gti�Black T'99 Gti - may she rest in peace - written off in a shunt on the A329m |

Is the engine standard or higher compression? Mine was always fine with a standard engine but when I put my new engine in with higher compression it was sluggish, but then it did always start. I changed my starter for a diesel starter which was brilliant but I couldn't live with the additional weight so took it off again. ________________________________________ Oulton Park in a BTCC 306 vid 1Oulton Park in a BTCC 306 vid 2 Lap of the 'ring |

Like I say, probably 1.5m of 170A cable to shouldn't be too bad.Think it might just be the battery is tired, started 100% with the jumper on it. Possibly not getting charged enough by the alternator ________________________________________ Rallye Race Car |
