Biturbo V12 W124 Made by Stern Garage

That's beautiful. I'd love to see undercarriage photos / videos of all the custom heat exchangers up front (especially the relocated custom AC condenser).

Note this was a USA-spec car, it has the yellow emissions decal over the passenger side headlight. However, it has a metal VIN tag near the hood latch which is not standard on North American cars - why was this added? :scratchchin: Was this the car shown in an older video that arrived with major engine issues (I forget the details)...?

Looks like a custom-modified cluster indicator strip, no ASR light (replaced with "EXH TEMP") and a CEL added. Interesting. :detective:

If the speedo is accurate (they often are NOT accurate at high speeds), indicated ~305kph is ~190mph. More interesting is how quickly it pulls from 150-250kph (95-155mph)... indicated 10 seconds. That's insane. Estimated 0-155mph would be around 20 seconds?

Some additional data from the video:
~6 seconds from approximately 75-175kph (45-110mph).
~8 seconds from approximately 50-185kph (30-115mph)
Would LOVE to see real data from a GPS-based performance meter.

Note he mentions aero issues at an indicated 300kph: the hood lifting, and the sunroof starting to make noise as well. Next step is wind tunnel time along with pressure meters under the hood to streamline some of the airflow at Warp 9.

:jono:

@gsxr Good points and observation. I also suspected a lot of wind noise from the sun roof, maybe bad sealings?

But with this serious power in he would require assistance downforce on the front bumpers that was implied from my design and maybe could aid the pressure on the hood to sit down. But this build is an inspiration and amazing manifestation to witness in todays era which going in right direction for the future car enthusiasts/tuners.
 
Yesterday Stern Garage held a car meet (Benzbash) right across their workshop. The car was unveiled there along with a W140 V12 Biturbo build. Here are some photos i took of the car:

Thank you @MercEdi ! Indeed it looks like a single electric fan behind the radiator … and note the black panels to the left and right of the radiator which forces all incoming air through the radiator.

Nice detective work, Jlaa! that looks like an "SG Special" fan... not OE brushless with PWM control, and possibly not with proper shrouding either.

It's just incredible. I would be actually scared to drive W124 this fast. It was probably never designed to reach more than 300km/h. You can actually see the hood lifting around 180km/h probably because of worn out hinges. There is also something flapping around in the front left corner.

Besides that, this car just goes like nothing. No noise, no engine sound, it almost feels like an electric car. I'm more than impressed and my mind is blown.
 
Crazy performance! Love the firepower but am not a fan of the styling/visual modifications. To my mind it would be much more fun to do a 65 engine transplant and keep it visually standard as much as humanly possible. Think standard appearance bumpers and custom 19” eight-hole wheels to accommodate the bigger brakes with matte black 6 pot calipers. Standard interior, original two tone pain job. Much bigger surprise factor than anything else on the road 😍
 
@Kridre Would you mind sharing the time stamp where to observe that the hood is lifting? It is kinda hard to catch that one!

@TerryA It would have been a perfect match I believe! Especially the downforce is required on this modification. We shall see what future holds. The E900E kit will be made as soon I'm done with fittings and will be built late this year or finish at early next year.
 
Funny fact the Mechanik Gloves:-))))))))))but i think is a trick for or against GermanRules .When you take a race for testing Highspeed .You Brake The Law and can be Arrested.But when you do this allone it is under in certain circumstances the same.Also you want film this ,you muss feel as an Criminal.
For maybe 2year here for my Housedoor the A2.An Czech Guy with aBugatti Veron drove 400 .Film this and do this in internet.
Oh real schocking .the Goverment take on Investigation for race with him self for climbing max Highspeed.
But the German takes to big mistakes. First was not an indigene German Idiot.He was an Czech.and second the Veron was his own car.
Also the guy was an Millionär(Has Money enough).Also many bla bla bla in the Newspaper and after 2or 3 mouth Caase closed.
and so we are all criminals in our own cars:jono:.i can speak only for Germany
 
@Draginev Look around 3:50, maybe I'm just seeing things, but something it's definitively not right there.

Hood lifting at higher speeds it's not that uncommon, I had the same issue that was resolved by replacing two hood hinges with brand new parts.

I don't see it in the video but it is a common issue, the W124 hood starts to lift above ~280KM/H. It happened with the Brabus and they had to weld a reinforcement plate :D

I noticed the Brabus style navigation system integration under the radio.

Its a classy Restomod from Stern-Garage and credit is well deserved!

Is the issue the hood lifting at the leading edges by the headlights, or at the trailing edges by the windshield?

:124fast:
 
Pity there was no GPS to confirm vMax. The analog speedometer can be wildly inaccurate near the top part of the range. I recall seeing a stock 036 speedo that was within 1mph at indicated 100mph, but at indicated 160mph the GPS only read 150... that's a significant difference.

In this video, the indicated 312-315kph (194-196mph) could possibly be a record for any 124 chassis, if accurate.

In our case (well, first owner's) it was lifting from the leading edges. He said the locking mechanism bent the radiator cross member at ~290KM/H, so they had to weld the reinforcement piece below the option codes plate. That's not the only victim though, 3 turn indicators and a bird that nearly went through the windshield!

I installed the the OE filler panel on the sides of the Headlights.

Unfortunately the left side hood hinge with lock mechanism is NLA, although the early hood hinges without the locking mechanism is still available.
