I think you are roughly describing the “floating seal” design that we are using to seal our rotary valve. The oil really isn’t as much for sealing as it is to help prevent wear on our expensive and hard to replace valves. The valves alone consist of $5000 worth of machined, ground, and coated components. They are…

I guess it depends on the vehicle. I found it really quite easy to get the drum brakes off of my 61 Austin Healey Sprite. However it probably only has 50k miles on them. I am not looking forward to the day that my 99 Oldsmobile 88 needs the drums taken off, they look properly rusted on.

I spent 3 years of my life with an e39 M5. Many people are wrong that it will be in the shop constantly, but it will be there 1 or 2 times a year. They are truly wonderful cars in every qualitative metric and most quantitative ones. That being said, to use one as a city Uber car would be difficult as in the city I…

Best this year had to be yesterday when I drove a 1980 Grumman Box van with a stock 454 Chevy V8 and a 4 speed stick. We found out with a little prodding, it did impressive wheelies.

Fully agree, I have wanted heated shift knobs for a while now.

Fully agree

Reliability mostly.

100% designed ourselves. Built about 50% of the machined components. Sent the other 50% to some local machine shops that we worked for and with over the years. They did the big stuff and high tolerance stuff that our machines were not capable of.

You absolutely nailed the beauty of 90s cars. Modern enough to have reliable fuel injection and electronic ignition, not new enough to have complex infotainment and extras you don’t need. My family has a fleet of 90s vintage design cars. It wasn’t until recently that we upgraded one car to a 2013 Mini, which is…

I concur. I daily drove one for 3 years. The first comment from every first time passenger was on how beautiful the interior was. Granted mine was a stunning caramel example with highly polished red wood type trim. It was comfy too compared to most modern vehicles, the seats actually had some padding.

The smoke really isn’t an ecu tuning thing it is much more based on how much oil we have drip feeding on the valve. At this point we are using very little oil on the engine but the catalytic converter is so plugged with oil it is not burning off to quickly. Thankfully the cats on the car appear to be brand new along…

If you changed the valve geometry and the speed at which they spin, yes you could, same principles apply to a normal cam driven engine.

I am glad we could peak your curiosity! Curiosity is a large part of why my brother and I did this.

I can disclose pretty much all of it. Nothing is really novel and new here, most of it is even patented.

You sir have good taste. I love the 5 spoke M3 wheels.

Heat prevents you from doing this. Though there have been a few outfits make cylinders out of glass so that they can study the combution process.

I guess I don’t quite follow what you are saying by throttle blades?

Meh, in the end of the day it is just a new 3 series. Where as for slightly less, I purchased a phenomenal to drive e36 for $3000, put maybe $200 into it to make every single last feature on the car work. It looks great, it was fun to drive, and sounds epic.  I am also not stuck with a new BMW with all the…

Yeah, that is the only thing not correct in the article. I managed to hit second gear wad the comment. Though once the engine gets up to 3000 rpm, it will spin tires in second on grass.
