    supercharging a carburettor

    Yes, must be https://victorylibrary.com/tech/supercharger/super-carb6.htm distinguishes both methods A 1340cc Harley with supercharger has 32.5 pilot and 172.5 main jet in a single 42mm Mikuni carb, blow-through.
  3. I have a 6N that is blowing a dark grey/black foam through the air vents, often into my eyes. Grrrrr! I assume this is a filter between outside the cabin and the air vents so it is quite important. My questions therefore: - is this indeed what it is? - a part number would be amazing. - is it easy to replace? I hope the entire dash doesn't need to come out. - do I need it? Thanks.

    MS3 and Trigger Wheels

    My understanding is that it's only MS 3/3x which will give you full sequential but one of the other MSs give you partial sequential whatever that means. Is it possible to fit a later hall effect distributor to the mech head? Good luck with the clutch end trigger wheel. Please let me know if it fits well because it's something that I may consider for the future on my MN block. If you have problems with your MS there is a lot of support on their forum. Every question I have ever asked is answered very quickly. Although their advice when I inquired about the possibility of having different maps one response was that I should be more careful on the accelerator!! So I am hoping to have 2 turbo boost tables which I will switch from the dashboard. One table will have higher boost. It's not entirely clear how many signals are necessary from the cam but mine is set up so one signal gets to the MS every two revolutions of the crank. Is that enough, I don't know.

    E10 petrol

    i think there are different ways of blending in the ethanol and it can be more oxygenated. Perhaps France has different blend. Needs more research. Water in my tank might have been rain dripping in higher pinholes than the petrol dripped out, but I think it was just the very long period car mostly stood with not much fuel autumn to spring. It's vent to air tubing was dodgy state so no inverted loop connected which might work as simple vapour trap. Modern (90s) cars have unvented tank with carbon filled capture canister for petrol/ethanol vapours. Damp air should not get in - even when filling you'll notice the trapdoor for the nozzle. I always thought it was to stop mis-fuelling with diesel, but now I'm not so sure. The canister stops evaporative emissions harming environment , the vapours are let into combustion once engine warmed and some people delete them. Maybe French MOT checks you have not done that? Guess. If it's an open tube as the petrol goes down, (possibly damp) air gets sucked in. But surely people plug the tube when they delete the canister?

    MS3 and Trigger Wheels

    Thanks for the info Phil. I don't really want to use a bolt-to trigger wheel as I want a factory looking install and not worry about making brackets and stuff I mis-identified my MS and its MS2 with V3 mainboard. Still sufficient for what I need. I won't be using full sequential to begin with so I assume I can bin the distributor off. This is my ideal solution as the dizzy I have doesn't have a hall sender (it's an old meh head)

    It's reading reviews on amazon that made me jump on here for other peoples xp. I know there are people out there that buy somethin for dirt cheap and then get "surprised" when it rocks up and is pretty much what they've paid for.

    E10 petrol

    Interesting, albiet concerning, stuff. I suppose the question for most people with older vehicles is going to be the availability of E5 and whether or not we're going to be forced into buying 'fancy' unleaded just to avoid the higher percentages of ethanol. I'd be relatively ok with it if all I had to change on my '93 Mk2f were fuel lines, filters and o-rings but the problem of water absorbtion and separation in cold temperatures is concerning - how is a modern car supposed to handle that? Light aircraft owners using modified aircooled petrol engines have long known about the dangers of ethanol - i remember my instructor telling me to watch out for water separation when checking fuel contamination. You pop a little flask over a valve on the tank or carb and draw out a sample to be checked visually for water droplets but if the bottom of the tank is all water you can easily mistake it for fuel (smells like fuel too!). Surely we would all need fuel filters with a water trap to be checked periodically? Thats an excellent article - thanks for the link. I wonder what the experience in France has been like since the introduction of E10? I always see heaps of '90s cars around when I visit, but perhaps they're mostly diesel?

    Watch out for cheap Sparco fakes. https://www.amazon.co.uk/SPARCO-SPC1012-Voir-Photo-16/dp/B007JFLTL8 check the reviews.

    Okay. That's a +1 for the Walser's then. I'll be sure to check out the Sparco ones too. Not seen them in the lists i've checked out yet. I'll be wary of the clips though.

    E10 petrol

    "First-generation direct-injection fuel systems with aluminum rails do not tolerate ethanol (ETP 2011). Corrosion product of aluminum forms a gel" might explain the Vw 2000 era incompatibility.

    E10 petrol

    Really good info here https://www.iea-amf.org/content/fuel_information/ethanol/e10/e10_compatibility#ethanol_cars (was Seat Ibiza sold in Brazil) Oh yes, vapour forming, using Momentum99 in July I found I had to insulate my fuel line from heat, but that might be a coincidental vacuum leak.

    E10 petrol

    Oh yeah, carb needle valves are usually brass. Maybe okay up to E10 concentration. They are a wear component, so it's hard to know if ethanol or wear is cause of any anecdotal reported leakage. No it is okay page 14 of Tomkins dissertation says brass is safe in Ethanol. but water in the fuel is bad

    Rubber pipes needs to ethanol proof SAE r80-j9 ? O-rings should ideally be viton. https://fbhvc.co.uk/storage/downloads/page/34/Dissertation pdf.pdf

    E10 petrol

    On pre 1990 car, yes, I hope so. On a carb, small adjustment to idle, slightly larger main jet, small advance to timing is probably sufficient to achieve optimal running (plus moisture precaution especially if not driven regularly). Though ethanol is. not kind to brass, so twin weber DCOE may suffer. No issue with Pierburg, Weber DMTx or others with plastic floats. Dunno what Solex PICT uses. My dellorto floats are nitrophyl so safe. Painting the float (with thinned POR15 or similar epoxy paint) will stop it being eaten and be the few percent heavy to let it have less freeboard for less dense fuel. (or the tang can be bent downwards) Either of these actions is probable new carb gasket and rubbers kit time. As for EFI. I need to understand why a Vw Polo from 2000 won't work on E10 or how E10 may cause damage, but Seat Ibiza from 2002 onwards is fine. Was Spanish fuel already bio-based back then? I imagine no engine management change, upgrade or compensation is possible for the changed combustion properties. The RAC data is mostly statistical, but draws on manufacturer compatibility coding declarations and assumes people will carry out recommended manufacturer mods if they exist ( a big if ) . https://www.racfoundation.org/wp-content/uploads/The_impact_of_E10_final_Wengraf_July_2018.pdf (i must try and find a Porsche Model Missing in Practical Classics).

    Stateside Polo

    G40 wishbones should have a rose joint on the inboard end - they're not so easy to find new. If normal polo ones have been fitted, simply replacing the bushings with polyurethane items is the next best option. Easy to find too! 😎

    Stateside Polo

    Looking to order new control arms (wish bones) for both sides of the car. I haven't been able to track down any OEM pieces, ant input on the best aftermarket brand? Or am I better off popping in new bushings into the old arms?

    Hi guys, looking for a passenger door to help with my rebuild had bought one on eBay but the guy didn’t send it after two weeks so got a refund 🙁. Also looking for a rear window seal as I accidentally ripped mine.

    NO VALUE SPECIFIED

    E10 petrol

    In your opinion is this likely all most of us will need to do? I've read that the gonvernment was consulting to 'force large vendors to offer E5 alongside E10' but it looks like that was done under Grayling so I won't hold my breath!

    Seat covers

    Walser's are good, had some that lasted about 5 years. (not allesandro). Before that I had a set from Lidl or Aldi that looked like real leather. Headrest covers are a waste of time. Now switched to some Sparco branded, but I have transferred the metal clips from the Walser as these new ones have rubbish plastic. Got a big hole in the side for the seat airbag I don't have in a 1984 car.

    MS3 and Trigger Wheels

    I put the trigger wheel on the pulley end on an adapter that bolts to the 4 holes that the pulley normally bolts to. There is enough clearance in the adapter for the crank bolt that holds on the cam belt pulley. The alternator pulley has been narrowed by about 4 mm so the flange has now gone. When the trigger wheel bolts up it supports the pulley and is hard up against it. The trigger wheel came from EFI co.uk. I am running MS 3/3X which gives sequential injection and fully programmable ignition. The ignition will be wasted spark so the distributor will only supply a cam signal. Let me know if you have any MS questions and I will attempt to answer them.
  23. Many thanks for that breakdown. That makes perfect sense. Nice one 👍

  26. Idle stability hysteresis breakdown I think what happens is this. If the plate movement is sticky and it does not close up when it should more air is sucked in by the engine's vacuum of descending pistons with open inlet valves than should be, so the lambda senses the mixture is weakened and lengthens the injector pulses, then engine speeds up more and overshoots, so cuts injector pulse time, and it repeats giving hunting, surging rather than smooth idle.
  27. Gave the throttle body a damn good clean and it seems to have done the trick Cheers Four associated error codes cleared too. How can some gunk on the walls of the throttle body have this effect on the idling ?
