Millercarbon's Mega Moab Mod Meander


One of the all time great automotive engineers, Norbert Singer, was a key player in every one of the 16 Porsche LeMans victories from 1970 to 1998. His dominance was such that at one point Porsche had won LeMans more than all other marques combined. This was all accomplished by building on the already solid foundation of Porsche production models. The air cooled flat 12 in the 917 was really two flat sixes combined to make 12. This car so dominated motorsport the rules had to be changed to stop it!  

So Norbert Singer modified Porsche production technology to extract the absolute most for racing. His legacy is today’s Singer Vehicle Design https://singervehicledesign.com Norbert doesn’t make for a very good car name so they called it Singer. What is a Singer? It is a modified Porsche. It is in essence a hot rod. What Norbert Singer did was make the most hot rod racing Porsche. What Singer does is take that to the next level, capturing every aspect of Porsche right down to excellence of design and aesthetics.  

I am not anywhere near the level of Singer. But that is the spirit of what we are doing: taking an already world-class design and hot-rodding it to be even better. Well, better for me anyway- or so we hope!

The early modders started with substituting off the shelf parts to get more power or less weight. That is pretty much all we are doing here. Would be cool if some day people are doing this with a lot more sophisticated approach. Maybe they will. Maybe even I will. For now though we have the current crossover project.

My approach is pretty simple: better parts sound better.  

This lesson was learned back in the late 90’s with Linaeum Model 10 speakers. The designer had a new tweeter and told me how to modify the crossover for it. Simple mod, one cap, one resistor. Bought the parts from Radio Shack, put it together, sounded like crap. Absolute horrid crap! Called him up, he said those parts are crap. Said Musicap, Vishay. But they measure the same? Just do it. I did. It worked. Even though they measure exactly the same, the sound difference is off the charts.  

Even though they measure exactly the same. There is a lesson here. For those willing to learn.

So this is the essence of it: Eric Alexander has made a speaker the equivalent of a Porsche 911. Even better: an affordable Porsche 911! But after a while with my 911, after learning what makes it drive and feel the way it does, it was only natural to change the shocks and torsion bar and other items to bring out even more of what I like so much about the 911.  

That is what we are doing here. Hot-rodding a speaker. Thank you Rick for the metaphor!  

The parts are on order. Next week the fun begins!

millercarbon  I had a flexible car that I autocrossed at Porsche meets in Tennessee.  The track was a highly banked oval with cones down the straights, and a big drop off into the center X section that made it a figure eight.  My Supercharged MR2 actually wore the paint off of the door sills, because the body flexed so much that the door rubbed on it.  This was the bane of the SC MR2,  because they only came with T-tops.  BTW,  I did have a fast time of the day in my Turbo MR2.   My boy had a 90 advertised hp Subaru GL with the huge Buick Riviera type rear hatch window.  It beat a third of the Porsches.  That was fun. 
rixthetrick   OK, My Supercharged car was a first generation 1988.  It was not available in the states without T-Tops, although there were a few people who did add the equipment on their own to the non-blown car.  I lost to one at the Dog Wood Gran Prix.  Unfortunately, most people did not realize that the engine blocks were different, with the S/C engine block. etc. being much more robust, from a spec series race engine.  My Turbo was a second generation 1993.  You are correct, it was available with or without T-Tops. I owned both cars for a few years  The Turbo is the one I used at the Porsche Club events, although the few series championshipd I won weer with the S/C car.  A former Porsche National champion father and son had a turbo, and showed me a a few tricks for my car, but never quite enough to beat them.  I used B&W (box) car speakers in the former car, with a Soundstream amp. 
     I really like B&W's, having owned at least one set since my early 1970's DM4, which was interestingly a DM2 changed from a ported to a transmission line cabinet.  Both used the Celestion upper mid/tweet and the Coles super tweeter that KEF used in their speaker, as did the famous Rogers min-monitors.  B&W's first speaker was this KEF that was bought to improve the crossover to create their first speaker, the Domestic Monitor.  This B&W, and the KEF from which it was derived, used the squashed 6 x 9 looking KEF woofer that was used to make the cabinet narrower, in order to lower Britain's VAT tax on cabinet width.     B&W then came out with narrow stand mount models (DM 2/II, DM7, DM14, DM16, plus the powered DM14 called the Active One.  Both designs were originally created to lower this VAT tax.     (Added that to make the topic home audio related.)

I have always added off the shelf stuff to improve my vehicles:  Pipes, ignitions, supercharger (S2000), and suspension improvements.  For somewhat normal use, I do not believe in touching the inside of an engine.  Exceptions have been smoothing out intake and exhaust castings (esp. FZR1000), and the porting of two strokes.  My S2000 is the strangest engine I have had.  It has no power below 4500 rpm, just like my prior 1986 GSX-R750, but really wails between 7200 and 9200.  My office used to be across the lake/pond from Champion Porsche.  I'll never forget how upset these guys were when they had to skip LeMans the first time; almost as much as when the local Flea Market/Drive In Movie guy had the very first totally factory built, actual 917 in the world.  Yes, Preston Henn, the guy who was able to skirt the heat the Whittington Brothers got, because they did not have any proof of legitimate income as to how they supported their racing...  Not to mention Nobby Clark's stories about Don Aronow.  Good Times, all!
