Lol I can't argue your point there

But your sls doesn't run 8s your clk is in a whole different league
I understand what you are saying though

roadtalontsi

it doesnt run 8's because getrag and benz wont give out any service information on the dual clutch gear box or tools to service/assemble it.

One word... tuning...

skaarlaj

Turbos can be very quick, but usually requires a lot of other drivetrain changes to make them work right. A good friend of mine made 647hp to the wheels with his 3500lb turbocharged 6.0 liter ls engine chevy c10 pick-up. on the same day, my little fox mustang made 414rwhp, and is about 300lbs lighter.



Calculations would say I'd get my *** handed to me in my mustang with over 200whp deficit, But in the eighth mile drag race I'm ahead of him by over a second. Turbo lag does suck, and playing catch-up is a tough *** game to play for sure. Also, neither of us spun too badly off the line at the track.

I do not think it would be much of a problem to get a couple of turbos installed. Getting the air to and from the turbos, out to the charge air cooler and back will take some work.

Also keep in mind you will have to replace that intake plenum setup as well. The way the throttle valves are placed and that sheet metal ducting to get the air to them does not look like it will hold boost at all. That I think would be the hardest part.

I would love to see a Turbo package for the M156. Tuning is the magic word here though. Hopefully people pursuit it enough to get the tuning right.

All other major components to the build are pretty much off the shelf parts. Some fab work for piping / IC mount etc. But its definitely doable with the right tune.

I think if someone pulled it off, they'd have a dyno killer for sure. Hell, I'd love to see what 8lbs of turbo would do with one of these motors!! Probably equivilant to what 13-15 lbs from a blower would do hp-wise, but I'd still give the race to the blower at higher boost though.

I imagine a 6.2 on TT could run 1000HP+ easy on something as simple as a set of BorgWerner KKK K04's. Imagine a set of Garrett GT3071R's...

I'm not sure how well this engine would hold 10-20PSI, that's a lot of juice to shove down the throat of an engine built for high output NA power. Especially on a 11.3:1 CR.

and ya'll think the weistec kits are expensive. lol . Price out 2x 2500$ turbos, an *** load of piping, intercoolers, new exhaust manifolds/downpipes, supply lines for oil and coolant, return lines to drain back in the pan. The problem has been the transmissions. Making a 156 make the power isnt the problem. Keeping the trans together is the issue. Weistec could've been in 8's and possibly 7's years ago had they slapped in a motec and a powerglide. But you cant be the worlds fastest mercedes when your not using mercedes core parts. Even these 1500whp tt gallardos with billet everything transmission still dont drag race because they blowup almost everytime.

skaarlaj

Yeah it stinks that anything made by or for Mercedes has to be so damn expensive.


2.3 liter twin screw blower for my ford svt lightning or cobra costs 4K and change, same blower for this car, with an inner-cooler and recirculating system and manifold and all the sudden you're up around 13K???


SS headers with cats for 03 svt lightning 1,200. I paid over 2K for a used set for this car, and it feels like I stole them, hahaha. Oh, and the lightning will beat the snot out of this car in an acceleration race. Sorry for the rant guys, just kills me sometimes. Obviously an outstanding car in many ways, and does a lot of stuff real well, just costs more than enough to do so.


One more quick rant, I have a 91 fox mustang 5.0, that came from the factory with a traction loc rear-end to go along with it's 225hp rating, I buy a 450hp C63 that came from the factory with an open rear-end??? Because at 450hp it's an option, but on a little ford 225hp car, a posi unit is "what you get", wow Mercedes, "really"???

You make it sound like 8's and 7's would be easy with a Mercedes. I can tell you from experience it isn't.

roadtalontsi

hell no, not easy at all. but considering how far they've gotten with what they are working with. They are only a few tenths from hitting 8's, With all the effort they've put in, swapping to parts outside mb it could easily be in 8's. I've seen their cheesey traction control setup lol. Drag racing is much easier when all you have to worry about is putting the pedal down. The 7's are quite a stretch and wouldn't be possible without gutting out and in my opinion modfications that destroy a street car.

Im not even in 10's in either one of my cars. Mostly time and money restricted. Hoping to see 10's with both pretty soon.

ecampbell

Traction control? Who has this?

roadtalontsi

i dont know? perhaps ive said too much.
