    Hi Tony,

    I´m in the final stages of replacing the original PI system on my 73 TR6 CR.

    I got a set of 2500PI bodies which I use to carry the injectors and a single throttle buy from a BMW 525i on the airbox.

    My concern are the original rubber hoses between airbox and throttle bodies. Mine are old but still strong.

    Did you experience any problem with collapsing?

    Regards

    Hi Heinrich/Graeme,

     

    I am now using 6 butterflies. I was concerned about the rubber connectors but your method certainly looks efficient. I changed back to 6 individual butterflies for better running. I now have instant acceleration and the engine is definitely more brisk. Interestingly, I had to re-tune my VE (Volumetric Efficiency) table as more air was allowed in... this is obviously more efficient than using a single butterfly with the plenum. I also fitted K&N filters to each throttle body and love the sound these make, very much like Weber carbs.

     

    I also made an overhead throttle linkage which makes it easier to tune my butterflies.

     

    Cheers

  2. Had a visit from Tim Hunt and his lovely wife Sue, great to meet them. We went for a spin in my 6 (1st video), and Tim had a drive in the second. Kudos to Tim, he was used to a TR4 gearbox and had a challenge going to reverse but soon got that sorted. Will definitely stay in touch Tim.

  3. Roger, I spent 3 days trying all sorts of adjustments...yes, I tried everything even elongating holes also moving the window channels to the point I had to remake them. I then made a template of the window from plywood (with smooth edges), and had them made. They fit perfectly and this would have saved me wasting 3 days. If there was a way of making the rake of the windscreen more adjustable it would have helped enormously.

     

    Cheers

  4. I've still got the mounting fitted to mine, even thou I converted it back to original style. I've never had any issues with them drilled into the body boot pan. Had them like it on a Spitfire, My TR6 and a few of my custermers cars have had them like it with no problems

     

    Mine is done the same, I also used large washers (2") on the inside of the boot. Have had no problems whatsoever.

     

    Cheers

  5. No Alan, he said it 'seems to be'. But...it could be coming out of the top if there is no felt washer (likely), and running down the tube appearing to be a leaky tube fitting.

  6. One of the biggest challenges in using a cam with a large overlap is that not a lot of vacuum is produced. This affects the MAP sensor (not to mention the brake servo), which tends to fluctuate which in turn affects the settings. I got over this by fitting an alternator from a 4 wheel drive car which has a vacuum pump fitted. This was connected to my brake servo and I now have good, constant brakes. I also made up a breathing system for the engine which maintains a negative pressure in the engine and has virtually eliminated oil leaks. The only slight leak I have on the car now is from the gear selector rod o rings...not a good design unfortunately but I'm working on that.

     

    cheers

  7. So its like chess: If you grab it you have to move it......

    Andreas, put your name on the bottom of your posts cause people don't know what to call you.

  8. Question to Microsquirt users:

     

    Do you use alpha-n for metering as it has no atmospheric pressure box

    or did you add it and use speed density?

     

    Question to all EFI users:

     

    Did anyone get the single throttle body solution work properly

    together with a wilder cam beyond 280 degrees?

     

    Hi Andreas,

     

    Initially, I used a single throttle body and it worked quite well. I then changed to individual butterflies (using the original throttle bodies), and noticed a vast improvement in acceleration and drive-ability. I have separate air filters on each pair of bodies and an air feed to the filter area. I have now made this permanent as it gives the oomph I wanted...and it seems easier to tune for some reason. I also use 'Speed density' and my setup maps are available to anyone.

     

    Cheers
