Went to the Pod yesterday with the slicks swopped for 888s, so sort of street tyre, and ran a best of 11.9/114 and 1.7 60ft. Well pleased. Excellent mate, well done Once Simon stops playing about on low boost he should see some 11s runs too Yes i moved to the darkside

Cheers Brett, yes I gather it will be next year before the Simon beast is revealed 'Where does the engine go?' |

Latest dyno results gave 215 bhp, then 277 bhp with NOS, and 288 lbf. ft. torque. Power held up well beyond 6500 although peak was 6100. I'm using an Avonbar PH1 cam supplied by Ian Hargreaves and although it loses some low speed grunt it does exactly what want on the strip, running between 4 and 7000 revs 'Where does the engine go?' |

well done steve ...what boost ? Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

Boost was around 20/21 psi. When I tried a bit more the dump valve started leaking, now have a stronger spring on the way. Hopefully with that installed I can tweak the boost to about 23 and hit the magic 300 bhp. Don't think the transmission will take any more. 'Where does the engine go?' |

Have you considered not running a dump valve steve ?

Interesting theory Robert, could it damage the turbo if I shift too slowly? My shifting is not the best, combination of old age and excess of mechanical sympathy.. Edited by steve1275 on 10th Jun, 2021. 'Where does the engine go?' |

So back to the Pod yesterday, managed a new PB 11.85 @ 114.7, off a 1.71 60 ft. Car felt good, but there is more to come, as i need to launch the car better. I moved the intake temp sensor to the engine side of the NOS injector, previously I saw 60C , now 20C, significant cooling effect. 'Where does the engine go?' |

Thanks guys, and yes it was a little toasty at times. I picked up a high speed misfire which I suspect was heat related. 'Where does the engine go?' |

So a stronger dump valve spring resulted in more power, and I practiced gear changing as instructed. Went back to the Pod yesterday and ran 11.78 at 115.3, so well pleased with that. 'Where does the engine go?' |

Hmm, took the head off and found this. Bit of detonation in no 1 methinks. Although I've been running higher boost this year I'm also using MS109 race fuel, and if the det was happening all the time I feel the damage would be worse. However I did run out of fuel half way up the strip once, and also did a couple of runs on pump fuel. The ali scraped off the bore quite easily, and although I can see scuffing on the top land, the ring appears to be OK. Thoughts? 'Where does the engine go?' |

Do you think that was caused by the car leaning out when I ran out of fuel? Normal AEM reading is around 12 on the strip. 'Where does the engine go?' |

So, back to the Pod last Monday, lovely day for it, ran 11.72 at 115.66 off a 1.68 60ft. Dump valve ok now I've realised that the MS109 fuel gets into it when i'm using NOS and this caused big wear and sticking of the piston if not cleaned out. I flush the rest of the system anyway.
