There is also a detailed story with many pics on Johan's website about the reman of the engine.

Last year my wife and I got a chance to see Carroll Shelby's personal AC Cobra after it sold at the Barrett-Jackson Auction in Scottsdale, AZ. It was sweet.

And this replica looks awesome, but where the heck is the fan?

Actually it still has the original 750 radiator
Only positioned much more to the front. Cooling is done with an electrical fan instead of the visco coupling.
Here is the story about the engine rebuild.

Ditto!

I'd love to video of this thing run.

What an amazing writeup!!!

that's really cool. i want to hear it run with those side pipes. what's it sound like?

Shogun, thank you so much for sharing that with us. Do you know Cor and Sean? If so, tell them that I'm naming my children after them.

That has to be the all-time best write-up I've ever seen, ever! That project should make SportsCenter's Top Ten Plays of the Week.

The part that really impressed me was this broken bolt recovery. I was on the edge of my seat!

It looks great! I didn't realize they had gotten this far with the car very neet, tho he complained about the hood clearance, all he had to do was switch to dry sump like I did and he coulda dropped the engine 6+ inches. I have almost 12" from the intake ports on the heads to the inside of my hood.

yes, you did it nicely with the dry sump

Can't find the pics of the dry sump anymore, maybe you post the link again.

Edit: found the pics, here

thanx, engine is upside down but here's the new oilpan and second pic is the original pan.
They coulda gained a ton of clearance, still a cool project, I just prefer the dry sump :)

Hi, what's a dry sump?

In a normal wet sump oiling system there is a oil pump inside the engine in a wet (oil filled) pan. The oil that isn't under pressure in the engine is in a pan at the bottom of the engine. In a dry sump system any oil that has drained to the bottom of the engine is sucked out by an external pump and stored in an external tank. Doing this allows the the engine to be closer to the ground because there doesn't need to be a pan to store it. The stock pan on the bottom of most engines has to be big enough to hold 4-5 quarts of oil. The use of an external tank allows the oil to cool down and allows air bubbled to dissipate, which means there is a better chance of an uninterrupted flow of oil at all times. AND keeping the oil away from the bottom of the engine keeps it off the crankshaft which also helps improve power.
The downside is it's expensive, but what isn't on these engines? lol
I run a 3 stage external pump (two sections suck oil out of the engine, one pumps it in) two filters and a three gallon tank.

I read his write up and it is great. I wish my engine looked like his after he beed blasted and cleaned it. Plus that cobra must fly!:buttrock It weighs 1100 Kgs and that equals 2420 lbs as to the 4500 lbs it weighed in the 750 hold on for your dear life.

This definatley gets cool points but in a car like that it seriously lacks power and possiblity of adding more power. Before I built my 561 rwhp rx7 I considered getting a cobra kit from factory 5 racing. I even toured the facility in mass which was really close to my uncles house. Anyways one of these cars will attract ever performance car owner ever to want to race your cobra. So you are going to need 450/450 on average to keep your average stock muscle cars, ie new vette, cobra, gto. Now with the modded car schene you will need all of around 450 to play with what's out on the street these days with all the advancements in turbos and superchargers. I say you will regret not dropping a crate ford motor with a kenny bell supercharger in this car.

A stock M70 engine has about 300 hp, but Jimmy had a good point about how light the car is. I think this car could handle a rear differential with an insane ratio, and that would really make a difference against heavier muscle cars.

And maybe you could even cram a supercharger in there.

One thing that's worth noting is a BMW engine like that will last forever.

You lack vision because that motor has the potential to be a beast but most domestic tuner type people lack the experience/resources to make it happen. I really hope you don't consider a stock Ford Mustang GT to fit in that catagory of muscle car because my 18 year old 7 beats them all day long with a slush box automatic. Also if you read the article then you would have noticed that the guy, Cor, wanted a different motor from the norm and almost everyone and their brother with a replica cobra has a Ford crate motor like the 427.

I am willing to bet that a M70 with intake, cams, head machining, port and polish, and exhaust can make over 450 horsepower and torque. Any takers?

can anybody dig up videos on this car?

that is probably one of the sweetest rides I have seen in a while. The v12 has HUGE potential even with mild tuning and machine work.

M70 - V12 SOHC 24V. 1988-1994. 155kg 341lbs
Used in E32 750il, 850i
5.0 (300bhp)

300bhp in a 1200lb? car must feel like you're attached to a rocket. :D

Thats an awsome car, it's cool when people try something different.

I hope you give me enuff credit to know the difference between a 2004 mustang gt and a 2004 mustang cobra. I never said the gt was a muscle car. And also the numbers I was listing were rear wheel hp, not "crank hp". Monster difference. I do give credit for trying something new, but I will recommend looking into adding some boost to this car because remember you added this engine to the "holy grail" of all race cars. When you are at a light no one cares or even knows you have a experimental engine set up, all they care is they stompted a shelby cobra/replica.

And trust me you will have everyone from classic rides to turbo honda civics wanting a run.

From the looks of the vehicle, this doesn't look like it will see much street, or even track racing, therefore it may end up being strictly a show car, which then an "experimental" motor setup will be greatly appreciated.

Cool,
I did want to sound like I was giving you guys are hard time.

A local older gentleman in woodbridge, va has a kit with a 90 5.0 mustang donor. The sales people who sold it to him must have told him with that stock 5.0 engine he would have the fastest car ever known to man. I saw him one saturday in the parking lot of the highschool and he had set up cones and was kinda doing his own autocross so I stopped with my rx7. He tried telling me some bullshit about how he was "tuning" his suspension. Then I asked how are you going to do that, you don't have a adjustible suspension. Then he gave me some shit about how rotaries sucked and the asked me how many cubic inches my "little" car had. So I told him 1.3 L. Then he reminded me that he had 5L. Then he was a little confused why it looked like I had 2 engines. Which I had to explain to him, one is the engine the other is a turbo with a hps cover and it seems to be about the same size. Anyways we were both headed up to the steakhouse to watch football so we made a wadger for beers and lets just say he lost horribly. The funny thing was the whole time at the bar he told everyone how his motor was on its last leg and next time we all see the car it will be supercharged with a new "built" motor. So I guess I cost him about 7 grand.

a TT swap with over 600 Hp should help you keep up with most street fighters out there.........the M70 loves turbochargers....

Or this car (http://rover.ebay.com/rover/1/711-1751-2978-71/1?AID=5463217&PID=2518995&loc=http%3A%2F%2Fcgi.ebay.com%2Febaymotors%2FTwin-Turbo-BMW-750IL-DINAN-VERY-FAST-SLEEPER_W0QQitemZ170158529307QQihZ007QQcategoryZ60 09QQssPageNameZWDVWQQrdZ1QQcmdZViewItem) because no one in their right mind would think an old beater 750 would be such a rocket ship.

Bukwild: If you want a really good race in Woodbridge VA then you have to find a guy named Alex Lane because he has multiple cars that would stomp almost everything: 650whp Drag setup Camaro, Blown E46 M3 Convertible, and a Blown 1000bhp/875whp Corvette. Also a 5.0 V8 Mustang motor only came with 215bhp and 300ft-lbs originally so unless it was pushing a lot of boost then it has no chance against any real performance engine.
