#featurethis: Twin Turbo Hummer-powered Benz

Today’s #FeatureThis submission is a rather wild one, and not surprisingly it comes from Northern Europe where mental car builds are the norm rather than the exception. The car in question is a 1980s era Mercedes Benz 500SEC submitted by Speedhunters reader Kimmo Blom of Finland.

This what the SEC looked like when Kimmo’s friend Petri Lemmetty began the build – a solid and clean example of what was at one time Mercedes Benz’ flagship coupe.

In its current state, the SEC doesn’t look terribly different than it did before the build began, but beneath that classy bodywork it’s been transformed into a completely mental tire roasting beast.

Like most of the crazy builds from this part of the world, the goal was to have some fun at track events, so the big Benz was totally stripped down and rebuilt to what is essentially full race spec.

During the process of the build the car was converted from left hand drive to right hand drive, something which Kimmo says is the opposite of what’s typically done in Finland.

In order to make the old Mercedes chassis better suited to going to sideways on the track, the car was outfitted with both front and rear suspension from a MKIV Toyota Supra.

When it came time for a powerplant, a six liter GM LQ series V8 from a Hummer was decided upon. With plenty of horsepower and torque available it’s the perfect choice for the big body Benz.

But there’s no way a simple naturally aspirated V8 would cut it, right? The big Hummer motor is fed by a pair of Holset HX40 turbos with custom-made manifolds, piping, and intercooler.

As you can see from the dyno sheet, the car puts some very healthy power and torque numbers.

The car was originally running a Tremec TKO600 transmission, but that gave out during the dyno session was then replaced with a NASCAR style Jerico four-speed.

Let’s not forget the big Wilwood brakes at each corner either…

Here’s a clip of Petri testing the car out this summer. Naturally, the twin turbo V8 sounds brutally cool as the car slides around the track with total ease.

I’ve always thought about how cool it would be to take an older European luxury car and build into something crazy. In most places they can be bought cheap, they look cool, and their big engine bays can fit damn near anything you can think of. Petri’s SEC is a perfect example of this idea being fully executed.

Thanks for sharing!

Cool build

 

for the kids debating about  this hummer engine. It's Gen III architecture.... Which is LS architecture... You see a composite intake, GM coils and referred to as an LS1 or LSx and think it came from a f or y-body... funny how someone calls it a truck engine and suddenly it's "cool" and "different" to you.

 

Go buy some green and purple shoes and a bright yellow hellasomething shirt, kiddo

 

- pretty sure all this coffee kicked in after "Cool build"

am I really the only one who was bamboozled into thinking this thing was sporting an old 6.2 diesel? I read the word Hummer associated with cars and I automatically picture an H1 HMMWV. lol

Is it RHD due to special suspension/engine part clearance?

I know this is a merc but do BMW do a equivalent model ? E39 7series coupe? If so that would be a cool build as well!

Now this is an original build. LQ engine instead of a LS and twin turbo too. I like this one.

Ever since I drove a friend's brand-new '93 R129 500SL at the Memphis track during one of my instructor warm-ups, I've wanted to build an R129 track car. One day...

The long Scandinavian winters give birth to the most crazy builds :). What about turning a stretch limo in to a drifting beast....would it be possible?

This is an awesome build. Great workmanship. And twin turbos on any V8 is nothing short of catastrophic self enjoyment. However, this LQ series engine itself is a chevy "parts bin" iron small block vortec version not far from an LS series engine. It is just silly to parade it around as being Hummer Powered. In fact I think it takes away from how awesome the build really is. Then again, I am not from Finland, and if I was I would probably be calling it Hummer Powered out of the humor of the chassis I pulled the engine from. Yes, I am talking to myself, through the form of a SH comment. How much of this are you going to keep reading? really?

Whoa. Cool. Is he running electric steering? Looks like the pump is in front of the right side turbo.

would love to see something like this in fd but it probably wouldn't pass tech for some stupid reason

shouldn't there be a cross-over point where TQ falls below HP?

Effin sick! Now why the US has only peeps that do LS swap in S chassis? Take a note and start thinking with your own head :)

Hummer eh? I thought I read that wrong. Respect for thinking outside the box.
