    I would try programming in the same curve that the original distributor had, as that would be the correct curve for your engine.

    Would love to know the curve values Col. Would they be in the service manuals? Or does someone have this on hand.
    Don't forget we have the alconi 675B cam.

    What are the numbers on your distributor? I will have a look in my books and see if I can post up the curve here or you can PM me your email and I can scan the appropriate pages and attache to an email for you.

    It's a 16 ts 807 - 6 motor Col. Not the 17 807 -10
    This block was from an automatic R16
    i'll check the original dizzy at work tomorrowthat came from the 807 -10. It's a Ducellier 673 from memory but don't rely on that

    The 17TS had weird curves because of the injection and the computer. I have them in the manual if that is what you want.

    Hi Sunroof. I thought about the TS but with the injection, it may not suit. But would be interesting to have a look and compare to others like 12/17G curves with carbs if others have those curves too.

    Just sent you a message John with advance curve info. Hope it helps. Was easier than trying to post a photo on here.

    Pm sent. Ebay job, no brand
    I also went to jaycar and bought a usb power socket and hid that under the dash so it's permanent and no cable everywhere. Ali bracket I cut up and painted black which just tucks in that gap between the dash and steering cowling

    Thanks Angru, really appreciate it. I have made up a blank curve, printed it off and using the info you sent me came up with a curve with values for the crank degrees and rpm. Really, I have no idea but it's a start.
    Anybody, feel free to comment and critique. Incase you see a ping staring at you

    I can have up to 10 points within the curve on this 123 Tune ignition.
    It's the vacuum advance that stumps me though, as you set this as well on this unit

    John are you still after the R17TS/G curve and or the R12G curve?

    Yes please. All of them. No harm in comparing

    With the better breathing of your engine, considering the bigger cam and sidedrafts, there will be an increase in efficiency, generally then less advance than the standard motor with little downdraft will be suitable. My modded 807s have varied cams, but one with 10.5 comp ratio and a 35/75 cam with 435 thou lift at the valve and twin 40s with 34mm chokes ran 32 degrees total, all in by 3800 rpm, with 10 degrees initial at idle, given the valve overlap.

    All of my 807s, despite the mods, like between 30-32 degrees total advance, on 98 with no vacuum advance fitted, although at light throttle openings you could perhaps run a total of 38 degrees, but with mechanical distributors I was getting a half second of pinging when I stomped on the throttle when I had a vacuum advance unit attached. I thought the pinging was caused by the distributor not being able to reduce its advance quickly enough.

    My next incarnation with the 16 powered 4CV is to fit programmable fuel injection and ignition, with a milder 30/70 cam with 400 thou lift at the valve with only 35 -55 thou lift at the valve on overlap, guess maybe 115 Hp at the wheels, we'll wait and see where it ends up. Given the 4CV only weighs 650 kg, and is 63 Years old, how much power do you need?

    Why is your speedo not working? They're not that hard to fix.

    I agree with Alan on the timing after spending time on the dyno, road driving then track testing at Eastern Creek and Phillip Island.
    I run twin 45 DCOE on two cars, both are most comfortable with least hesitation, good cold start and smooth progression at 10 to 12 initial and 30 to 32 degree total at 3000. I found if you move off the sweet spot by about 2 or 3 degrees they fall off in responsiveness quite obviously.

    In regards to how much power you need, I found that you have enough if you can spin both rear wheels in every gear until you hit the brakes at the end of the straight in top gear at anything over 280 kph.

    Just want to clarify your meaning of spin.

    1/ Spin rubber on tarmac or

    2/ Spin rim on rubber or

    3/ both

    Spin very wide soft compound rubber on tarmac of course. Tarmac is for racing, dirt for planting potatoes.

    Thank you Alan and Bustamif. Most informative. All I know, but learning more, is that this engine has 10.4:1 and the 675B Alconi cam which specs I don't know.
    Can anyone comment on the curves I added earlier?

    Agree, My race car runs 30 degrees at 3000rpm, 12degrees at 1100 idling and then 16 degrees at 900 rpm.

    I've seen this on a dragster's toolbox: Petrol is for cleaning parts, Alcohol is for drinking, Nitromethane is for racing.

    My R12 G replica ran Alans timing as does my R17TS with two by 45 DCOE Webers. My 17TS cam was to be standard 42/75/75/42 but I got a 42/75/75/53 for some reason only known to the cam grind man. That leaves me with lumpy miss at idle. But starts and runs fine. I spent a lot of time trying to get rid of the lumpy miss only to find the 53 degree ABDC exhaust opening instead of 42 degrees and have assumed that is the cause and not worried about it anymore. I'll try and get copies of the curves back on here later today or tonight.

    John finally got the R17TS graphs but I am sure they will not help much. What I have been looking for is my R12 G workshop manual that would have been better but I think I must have loaned it out and forgoten who to. Some one returned books to me after twelve years recently and I had forgotten I even had them until he turned up with them. Go for Alans figures are my suggestion.
