Not trying to be combative at all so sorry Doc. However, I do disagree. Your original question asked...

Also, it is here as reference for future members who search about heat cycling. The discussion can be useful showing all points including those that say it is completely unnecessary. Remember, keep an open mind! <cough>ATF<cough>

Is it allowed to assume that if others do it, they think it makes sense? |

Maybe it makes you happy that I work on engines since 40+ years, started at the age of 15 and spent a lot of time with somebody working as tribology expert in the oil and automotive industry. Unfortunately my English isn't good enough to explain some scientific aspects, especially molecular structures and how they change in a heat, cool, heat cycle versus the materials they inevitably touch or get in contact with. Especially in two stroke engines with their rather old-fashioned pistons. I accept all opinions and if you say it's completely unnecessary that is perfectly fine for me. |

What do you think on the matter Doc? I like to keep things simple.. Buy quality parts, measure tolerances on assembly, throw it together. Run to test for leaks, etc. Short test ride using some load on acceleration and deceleration to start bedding rings, and then ride it as per normal. |

I have a customer I deliver to had a Barra in his ute making around 1200hp, he pulled it last year and built a new one not quite so slow(allegedly) He hasn't dyno'd it yet though. |

I've kept mine stock as a rock as it's my daily drive and I don't have the coin to spare (not only tuning but also maintaining).. Relatively easy to get some decent figures with a fuel pump, injectors, valve springs, cat convertor, intercooler and a tune.. but most people then overlook the added wear and tear on the drivetrain. Especially if the tune is more on the aggressive side or the driver lacks mechanical sympathy. I think if I were going to do one up, I'd probably look at buying HP tuners, throwing in a couple of sensors and tuning it myself. Shame they've stopped building the falcons here |
