I have no idea what model magna the radiator is from, I went to pick a part to try and identify it but could not match it up. It has twin thermo fans and fits in the engine bay perfectly. also dead near fits the stock radiator hoses! I will try and get a better photo of it for you. I did a bit more work on the weekend and now all the lights work, horn works, heater, wipers, seat belts, doors, windows everything except for the tacho! Next step is club rego. hopefully in a few weeks I can legally drive it |

I threw it in the bin and bought a new one but I did trace all the wires and know where they all go and how they work so I can point them out to you. |

I spent a bit of time stuffng around with a wideband 02 sensor today and have the car running properly. it starts and idles perfecty once warm with an AFR of 14:1 any leaner and it pops slightly. here are the AFR's for rev range hard pull in socond gear 2000 - 13.5:1 3000 - 13.2:1 4000 - 13.8:1 5000 - 14.2:1 6000 - 13.7:1 (have not taken it to 7,000 yet) seems to taper off quite quickly from about 5,700rpm Here is the jetting and carb settings for the engine (wont really help anyone as the needles are MJN yoshimura needles and will be different to standard R1 needles. 1.75 main jets 17.5 pilots air mixture screws 3.75 turns out needles in the RICHEST setting I may have to step up to a richer main jet and lower the needles target AFR should be no leaner than 13.5:1 This was all done with a static timing of 15 BTDC using 98 ron fuel. there is no pinging but as soon as I connect the vacuum advance it detonates like hell! I thught about the idea of using a restrictor in line with the dizzy vacuum line to reduce the amount of vacuum seen by the dizzy in effect reducing the rate of advance. This is easily done. I have used restrictors in all sorts of applications in turbo cars before. You can use a MIG welding torch tip inline. I will play with this if I do end up putting it on the dyno. The car pulls pertty hard for a 1.8 NA engine and sounds pretty mean! using my mobile and racechrono, punching in the cars weight as an estimated 950 kg's with me in it and doing 0 - 100 takes 8.4 seconds... I thought it would be faster than this! I guess its got to loosen up a bit. it also estimates the horse power at 166hp. minus 20% for drive train loss and its a pretty respectable 132hp or almost exactly 100 rwkw! sounds a bit high to me, perhaps my guess on the cars weght is wrong or the software is nt that accurate. puncing the nubers into olline calculators give very close results so its possible! Will not know till I put it on the dyno in a few weeks. |

You would want a bit richer to allow for variations in ambient temps etc too. The 733a is good to 6000rpm. I found I could get to that easily on Lpg. Id guess its, the mixture leaning out. Bit weird about the vac advance, oh well just don't use it Isn't stoich 14.7:1 step it up to 1.8 or 1.85 on the drill bit. |

for outright power i to would want it abit richer. mine runs about the 13:1 - 12.5:1 and that seems to be a nice mix for my l18. wouldn't bother with vac advance just set it at 32deg @ 4000rpm. looks good should be pretty fast when your done |

The usual trick with webers an a hot L series is to have the mechanical advance come in quickly and forget vacuum advance. It may be possible for you to use vacuum advance, but the first thing I'd check is that it's connected to "ported" vacuum, not just a source on the inlet manifold. The vacuum has to come from the carby body (maybe bodies). The "ported" vacuum signal originates from a hole in the throat of the carb immediately behind the throttle plate. When the throttle is shut, there's no vacuum. When it's wide open the vacuum signal is negligible. When the throttle is open slightly (ie; cruise conditions) there is a strong vacuum signal. This is what you want so it pulls on the vacuum advance, advancing ignition timing to improve combustion of lean cruise mixtures (and throttle response when cruising). You don't want it advancing the timing under other conditions (like full load, idle or cranking). If R1s have no provision for vacuum advance in their ignition system your carbs probably won't either. While it's possible to modify them I doubt it'd be worth the effort. Hope this helps. Please keep the updates coming! |

fantastic explination guy thanks! I am just going to disconect vac advance as suggested and run mechanical advance exactly as avised. I got my pipercross filter today and a jet cut flange to fit to the carbs. Will post up some pics when its been installed. |
