Dry Sump M113

[e500slr]

Has anybody ever done a dry sump on the 5.4 M113 Kompressor? I know the SLR is dry sump but I was wondering...

This could definitely net some nice hp.

Not sure if dry sump actually gets more HP but it allows the engine to be mounted lower down and further back to improve weight distribution and reduce understeer and after eliminate oil starvation at extreme acceleration and cornering.

On the other hand I have a couple of friends with R34 GT-Rs and one of them dry sumped his and he said to have netted 40hp. I can't confirm this but maybe you're right. I can't see why though.

stock oiling system is second to none. Reason for it in the SLR was already previously stated.

Dry sumps are the best for absolute oil control. Being able to pull vacuum is one way to free up hp, and getting oil away from the rotating assembly is the other.

For our cars a dry sump would be awesome, but the net gain for cost spent is not worth it. I think in our engines you'd be lucky to get 20hp. If you start pulling more vacuum in a daily driver your going to be hard on parts that were not originally intended for scavenging.

I run a pro stock style motor with a six stage autoverdi dry sump in a drag boat. on a motor that makes 1150 hp on motor and 1490 on nitrous. we picked up about 40 hp over a conventional oiling system with a vacuum pump.

The cost of dry sump system was $6000, not to mention building the engine to take advantage of a dry sump.

I'd love to see the details of the SLR motor with that dry sump system.

Just did some research, apparently a dry sump will reduce pressure in the crankcase from the vacuum of the oil pump and so it adds power.

The SLR is quite a different animal. You can start with its closed deck block and equalized fuel rail.

Sorry didn't see your post before posting my "research"

Does Mercedes sell SLR engines or does an engine need to come out of an SLR? I can't imagine the guy in Dubai bought several SLRs to make the SLR engined G55, E55 and SLK55 so he must have some Mercedes-Benz contacts to buy the engine from. I would also imagine that Mercedes does sell them since it's not impossible for an SLRs engine to blowup. With the amount of money people are spending on mods here if the SLR engine was available and not too much then it would be the ultimate engine for this car. Just slap on the mods that Renntech did for the 9.6 sec car and it will be one insane E55. Personally right now I don't have the time and energy to start modding the car. I haven't even done the 63 conversion yet but to be honest I wouldn't mind throwing 40k at an SLR engine and selling my engine. With the SLR engine there's no more "backyard mechanics" and "ghetto cooling mods". You'd have the perfect M113. So what is the cost, I mean just the engine without the gearbox.

Here's a couple pic's of the SLR's dry sump system if you guys haven't seen it before..

Per my dealer quotes $40K will just get you the S/C and coolers from the SLR. Getting a used SLR engine would be the way to go, but will be a very rare find and still very pricy! You can get every part of the SLR with just a Vin#. Google SLR Vin# and whala! A brand new M113 cost around $60K so I can only imagine a brand new M155 would be at least triple that.

I just purchased a used SLR blower and thinking very hard about buying the SLR's coolers and intake to go along with it. Would be very nice to have the SLR's intake system on a modded 55K! Only issue is that my hood will have to be modified..

JESUS CHRIST!! I was going more like 40k for the whole motor!! What a rip off, I know the SLR is a hypercar but even with those mods the engine isn't exactly an engineering masterpiece. It's an amazing engine but it's not out of this world. I guess they charge that much because they can. As for a used SLR engine it's not like SLRs are crashing everyday...and in a way that the engine is completely unharmed or whatever...and SLR owners don't just decide to sell their engines 60k for an M113?! That's more than 2 GREAT E55s in the states. Considering Brooke and E55amgrocket have already made over 600whp from their engines there is no way over 60k is justifiable for a stock SLR engine. What a shame, it would be the ultimate E55 engine

EDIT: Plus for 40k for just a blower and coolers an E63 could slap on a Weistec and heads and exhaust and make over 650whp like JRCart's CLK63BS and other 63s like Weistec C63s.

SLR all around is just

[loudandheard]

From what I read, the system is run mechanically. The just add a special pump that is belt driven. I would imagine that this could be accomplished with the parts above.

Yeah I could look at that motor part pic of the SLR all day long....

I called my buddies at the dealer for s*its and giggles. A new sparkly SLR engine ready to plug in and beat direct from Germany.............This was years ago so I am going from memory but I am pretty sure it was.......

































































































120,000$

[_AMG_]

Would be a great idea but feel unnecessary for street use.
If this car is being driven on a circuit then its definitely worth it.

[.trunzx]

I remember when someone dropped a valve in an e63 while under warranty. They ordered a whole new engine. $75,000 for just the engine.

Considering I've seen some SLRs in the states going for just over 220k that is a RIPOFF!!! I mean seriously Exotic has already fabricated some pretty nasty mods for this engine and a few cars are pushing over 600whp already. Cooling is one of the biggest problems that should be fixed but other than that for 120k you could buy a used GT-R and slap an Alpha 10 (or maybe Alpha 12) kit on it. They're delusional I'm pretty sure you build a Top Fuel Dragster engine for 120k I know they can't sell brand new engines for like 20k because then people will buy E320s and put E63 engines in them but still, over 70k for a new 63 engine.....when whole E63s are going for 20k less....

Who cares about a closed deck block though right? I don't think the blocks are failing in these cars and blocks aren't an issue at 600-700whp when made my Mercedes which assume they're quality blocks. I know people who have closed deck EJ25s (STi engine) running 500whp while others with an open deck running 600whp. I think rods and pistons would go off before a block does. I mean open deck allows for better cooling so... Plus hasn't Exotic sleeved one of his blocks?

There isn't normally a windage tray in the M113K, is there?

I think it does.

There is indeed:

Even lowly GM figured out basic sump management on my Gen-IV LSx:

Good to see you posting again, boohooramblers.
I insist we catch up over a refreshing pint when next you’re out this way. :cheers:
