Loving new Supra. Early experience and questions

[jchadwell]

BMW electronics/ computers are way more sensitive than a Toyota. Can't even leave things in the OBD port without it causing issues.

Would you want a Honda tech working on your Ferrari with out designated training?

Are you certain leaving something plugged into, say, a Dodge Ram OBD port wouldn't also be an issue? Look, if you are only comfortable with someone that knows how to handle a BMW working on your car, that's up to you. My only point is there really isn't anything special about our, $50,000, mass produced BMW Supras. Normal, every day vehicles today are packed with similar electronics and technology to that in our Supras. Hell, my wife's F-150 has as much if not more tech as my Supra and it was more expensive as well. There is no "F-150 tech" at the local Ford dealership. And don't get me started on the cost of a damn pickup anymore...

Anyway, let's not argue about something silly like this. We can both have our opinions and neither is really wrong. I will just close with this: changing a Supra's oil is literally a 15-20 minute job that consists of remove plug, drain oil, unscrew and remove filter, replace plug, screw in new filter, put in oil. That's it. The amount of issues people have with this is absolutely incredible and that a "Supra tech" is required just blows my mind.

The break in period thing is a gimmick, run boost through it for the next hundreds of miles to properly seat everything. If anyone says otherwise also, explain why race cars don't have break in periods. ??‍

I don’t own a race team or anything, Butch, but I reckon it’s because race engines don’t need to last 100,000-200,000 miles and are rebuilt every season, if not several times a season. Again, I’m not a genius but just trying to put 2 and 2 together.

Because an F-150 is a Ford. A supra internally is not a Toyota. No Toyota techs wants to touch the Supra. God for sake something happens in sue happy America. The owner is gonna lawyer up. It's all for liability sake.

I give up. You win. A Supra tech has to change the Supra oil to keep from getting sued...

I mean... you're not wrong... but still, every motor that i've put together whether rebuilt stock block/ FBO cammed or built block, we run boost through it and just do the good old 50,250,500 mile oil changes to inspect to make sure things are going smoothly and no abnormalities.. we run boost through them because that's how the customers will be using them; Beating the shit out of them. So far every motor has been a solid result and if anything, healthier than soft break ins. That's why i advise on hard break in because that's how the car will be spending majority of it's life..

Well said! I just drive the damn car & enjoy the shit out of em. Signed up for my 1st track day as soon as I got her. She’s still purring like a kitten in town and roaring like a lion on track… Regular maintenance required.

I’ll go as far to say I’d buy a used Supra from a track car guy over someone who’s babied the ? out of her. I think they do great when actually used. I have a buddy that is a car collector, has over a hundred cars. Talk about problems…. He has track cars too, regularly driven. Far less problems with those by far. Just my opinion and what I do. Go enjoy your cars and do whatever makes you happy! ? ?

If anyone says otherwise also, explain why race cars don't have break in periods.

Race engines do have break-in periods. Three actually.

Ideally, the first one is heat cycled by your builder. If they don't have a provision for this, you do it on the dyno.

Second, street miles, It's ideal to get ~50-100 miles on it before you really heat cycle it. Then you retorque the head

Thrid, after you push it. It's best to heat cycle several times, and re-check clearances.

Finally- we don't expect these things to last. A built engine probably has 50-100 passes on it.

The trans- even worse. We try to get 500-1000 miles on a new trans before sending it.

Word on the street, Toyota/BMW does a pretty good job breaking in these B58 stock engines (the one I‘m tracking).… Your thoughts? Thanks hombré

They're likely heat cycled; I don't know for sure. It's incredibly unlikely that every engine hits a dyno. The amount of time that would take is beyond impressive.

Even then it doesn't guarantee against failure. All the new Corvette Z06 engines are run through an engine dyno before being put into the car and we have already seen some early failures from them.

The engines dont go on a dyno. The car itself goes on rollers when finished and gets run through a simulated drive cycle with some full throttle pulls.

I can’t believe this to be true. Is there a source? Strapping a car takes 30 minutes. I’m happy to be wrong, I just don’t understand how this is possible.

Who the heck takes 30 min to strap down a car!? They need to be fired! I can strap a car in less than 10 min by myself haha.

You can't think of it as a normal dyno as this is a manufacture we are talking about. Think about the dyno being more like a jig to make a part. Car rolls on, you hit a button and it locks the front wheels in place.

No source. This is just a typical car manufacturing practice across all brands. I'll see if I can find a video to show you what I mean.

yeah. 30 minutes is egregious. When the GM plant was open in my old home rip, it was something like 1-500 cars were ‘drive tested.’ But nothing that would constitute engine break-in.

Yeah, you guys are a wealth of knowledge! Way more than I was expecting lol.

The only reason I don’t follow a long owner’s manual break-in period is because a local race team told me a long time ago it was okay. No engine mods or dragging however. And lots of good old fashion maintenance. Have 3k miles of mixed track and town driving on this one. So far so good…

Watch me blow up today when I pull out of the driveway ?
