    That's pretty rich coming from someone who picked Boralogist as his internet handle ...

    Brief experiences? Hardly that. I've already documented some of my experience driving this car at high speed and that was just my forays to and from that race over a 4 year period. I've owned mine since 1987 and have put 40K miles on a car I bought with less than 3K on it.

    If you have such a superior knowledge and experience driving this car how about sharing it with us. I share a lot of stuff about my experiences with my cars in order to help other hobbyists.
    I'm not making any money doing this.

    Take another look at that video which is of horrible quality and pause it at the front end shot where you will clearly notice that the headlamp buckets are being pushed up. That's another indication of airflow issues with air having trouble flowing through that tortuous radiator path.

    I spoke with my friend (former Bora owner) again yesterday and he thinks he's finally figured out why the Bora can sometimes get air into the cooling system. Pump cavitation is one of the things he worked a lot on eliminating in his Bora. It has a straight vane impeller which is very efficient at pumping but at high rpms is likely to cause cavitation more easily.
    My friend owns a company that's been in the pump business since the early 1930s. They now design and manufacture the cooling system servicing adapters and tools for companies like Snap On and others. Recently while developing a prototype set of adapters he was attempting to draw a vacuum on a cooling system found that he was drawing in more air into the system via the radiator cap's vent. So he wonders if you run the engine up to high rpms in 1st & 2nd then perhaps the pump cavitates and pulls air into the coolant via the cap on the reservoir creating lots of bubbles? Until those bubbles separate from the coolant and exit the system efficiency is reduced.

    It's something to think about.

    Hello---

    Have a tiny chip on my windshield which has led me to research a replacement.
    As we all know the Bora and the Merak share the same windshield, which lists on various websites for approx. $1,500-$1,750 in various currencies.

    What I did not realize until a few minutes ago is that the period De Tomaso Pantera also shares the exact same glass, green tint and all, with our cars!
    Please see:
    https://www.eurospares.co.uk/parts/maserati/bora/bodywork-lighting/bumpes-and-glasses-30329/117%20BT%2073479

    If so this becomes a relatively painless few hundred dollar proposition.

    Thoughts?

    Regards.

    Bob, I had to watch just to look for you. At 38:22 with the Bora. Great fun.

    Thanks B.,
    Not sure how I missed this post! Scrolling through the inventory box on the EuroSpares website had me a little confused, but I found what you're talking about at the bottom of the parts list: 695.- GBP vs 1,195.- looks like a nice savings..

    Have you gone ahead with the order and done any of the work? Let us know what you find along the way - any problems with windshield gaskets, trim, etc?
    Best wishes for the New Year,

    Hi Art---

    Agreed.
    Once I realized the Pantera connection, then things got even better:

    Amazing!

    Wishing you a Happy & Healthy New Year as well!

    Regards.

    Gorgeous Bora!
    Hoping that one day you would consider a full Euro bumper conversion!

    Regards.

    Thanks B,
    I've been thinking about it - I'm of two minds that are not yet reconciled.
    1.) It would entail major downtime. It's been almost 7 years of enjoyable privileged ownership, and a major refresh is coming.. A full conversion with revised silencers, rear sheetmetal and all, would be the only satisfying way to do the job. There are myriad hidden flaws that I'd be compelled to rectify while doing the bumper work. My last restoration of a running car, took 6 years. The complexity and diligence required to do the Bora correctly implies down time that would be painful to endure.
    2.) I could keep driving it. The US bumpers go pretty well with the dark 'Cioccolato Sfumato' paint, and I don't see the bumpers during the many hours I sit in the driver's seat, so I convince myself the bumpers have no tangible impact on my psyche. Out of sight, out of mind. Plus, the car would remain unmolested. No Bora will ever be converted to US spec, so the US bumpers are not getting more abundant. Maybe I'm hoping the more you all convert to Euro bumpers, the more I'll be the last one left.
    Cheers,

    I know of someone who had a damaged rubber bumper on a 75 fixed perfectly if that's what you're getting at?

    In one of the Bora threads I pointed out someone's rubber bumper adjustments which I thought looked pretty good. I beleive the car was in the UK and colored roso rubino.
    Otherwise you ARE looking at some pretty hefty frame changes in the rear to make it authentically European looking. The transaxel and exhaust mount very differently.

    Good question, Bob..
    When the time comes to restore the Bora, it'll be the big decision - Euro bumpers or not. I hadn't considered whether I'd restore the US bumpers or not.. Retaining the US bumpers would reduce the workload getting me back on the road sooner. What's needed mostly is underneath - it has some old welded repairs done below the battery box and along the rocker panels that isn't right, the rear lid gusset plate too and these areas are showing some surface bubbling, so some corrosion is setting in.

    Ivan had decent results drilling and collapsing the gas shocks in his US bumper spec Bora.
    Cheers,
