[@adinaiscrack]

why would put the car on the dyno without a oil change and new spark plugs.You're not getting a true reading. The tuner/dyno guys should of told you that

[@sweetdreams1DIAM0ND]

vahag y they are not pro tuners, just got the cheapest dyno that you need to install your wheels on, (means you wont the get the right reading because wheels have rolling resistance into them and reduce the hp and torque, and Im sure you dont drive without rear wheels) to get the audio and other simple wired stuff type of customers to trust them and think "look they got a dyno so it means they are sooo good at smaller things like installing my $20 speakers"

[@Dazedviper1]

I hear ya. Since these do bolt up to your hubs they will give you a higher reading. ALso they wont ever slip or bounce off rollers. They have mathematical equations that would fix it. To be a real world numbers.

[@ShadowSkullinc]

Your car is making almost spot on power accounting for 15% driveline losses.

[@andrejkostovski5172]

Tristen Sanders well since its only rwd 15% is alot of driveline losses,right?15% more likely 4wd

[@JamesMotorsport]

drivetrain loss is never linear 15% is rough rule of thumb for 2wd losses.

[@andrejkostovski5172]

presteronetj then how much will it be for the 4wd vehicles?

[@andrejkostovski5172]

presteronetj i just think its a little bit too much maybe 10 % is more likely

[@Sam-iy7us]

Andrej Kostovski that's a pretty standard figure it's more of a average the new gtr only has about 10%. Drivetrain loss but there some Subarus that have in the neighborhood of 30% + Drivetrain loss there's way too many variables so most people just use the 15% figure

[@trebor229]

First thing i would do with a neglected car is.. change the oil.. Even before trying to start it.. or is that weird?

[@TheRazvy1990]

trebor229 yeees it is.....first you must do acceleration test.....maan !!

[@jamesmcivor340]

trebor229 no

[@tjeizzHD]

Do you even know when the oil was last changed? if not.. a dyno-run would be considered the smartest xd

[@demondhaas7401]

that was on my mind as well.

[@OMGWTFLOLSMH]

Judging by the neglect this can has suffered, I'd say the oil was last changed in 2009.

[@omarawad2161]

I'm sure this car is screwed somehow. I'd love to see the service records. I wouldn't be surprised if the carfax showed nothing on the service history. This car was neglected big time.

[@graemewilliams1308]

In Oz they go for around $A65,000 & up.

[@DPCcars]

ic pump, my e55 gained 80whp when i changed it.

[@filippopages5135]

dyno with no oil change?that's nice

[@cha7260]

I believe it runs rich like that in the upper RPMs to reducing the chance of detonation being that it is force inducted. Having detention at higher RPMs can be catastrophic. I'm sure the stock tune is more on the safe side and you can get a tune to lean it out a bit to extract some power.

[@christianknight9016]

Lmao I love the guy trying to come up with reasons to do another run @ 9:02 “maybe do another one so we can uh, you know, get uh, actual..”

[@biohazardshrimp]

I would do a compression test on that engine. $8,900 or not that rebuild may not be worth it. $8,900 right? That's what you paid? I can't remember.

[@apangurra2775]

BioHazard Shrimp Think it was close to $9000, but I'm not sure..

[@marcog.3488]

Big fan from Milan, Italy. Keep up the good work man your channel is great !

[@tavarish]

Thanks!

[@snowbaordguru]

It's dumping fuel in because there isn't enough air moving into the engine with only one fan. That combined with worn out plugs causes the computer to try and adjust for the lack of air and maintenance.

[@-Rambi-]

I actually raced against one of these last saturday, sounded terrific. Beat it but if we were going for top speed than he surely would have won. My car; Supercharged Opel Speedster; 860kg - 308hp

[@DaddytechEnt]

*put some E3 plugs in it and some 8mm plug wires on it and try it again also a K&N air filter and you may well get your 400HP out of it at that point. you're close as it is but the E3 plugs will make a huge difference. also put in Mobil 1, Royal Purple, or Rotella Synthetic oil and clean out your engine before the oil change with Seafoam all of those things i just mentioned may even put you over the 400 HP mark and they are not super expensive upgrades and they will not only increase performance but also keep your car running better for longer. those things made a HUGE difference in the performance of my 99 tahoe and each thing was more noticable as i added each different item*

[@svtbird9613]

The 493/516 is BHP, which is the engine by itself without accessories. Even the water and oil systems are fed with external pumps so the engine can put out as much as possible. With the drivetrain you can take about 73hp off automatically (15% rule, but may be a high percent with automatic transmissions), and the accessories can vary in parasitic loss percentages. Yes, 365 is low, but its not too far off. New spark plugs, changed oil, air and fuel filters and that should bring it back to where it should be. Probably wont hurt to run a fuel system cleaner as well.

[@unknownunknowns]

Looking at the dyno, you can notice that peak torque happens before 2K rpm and from then on is flat for around 2K rpm more before going down dramatically. On thing I've noticed with MB cars is when you tap the accelerator, you get INSTANT torque and you just feel that 'push'. That can explain why MB cars tend to have LOWER REVVING engines without sacrificing acceleration. It seems they can do that because they can make the transmission ratios taller causing the engine to rev lower. That might explain why MB doesn't rely on an outside company to supply them the transmissions like BMW, Audi, Fiat, etc. They build their own. Because MB has lower revving engines, that can explain why Tavarish and other owners haven't complained about engine failure but (LOL) electronic failure that are irrelevant to the engine. And Tavarish seems happier with his SL55 AMG compared to his Aston. Also, it explains why MB is also in the commercial vehicle industry. In the US, it owns the trucking brand, Freightliner, and the engine manufacturer, Detroit Diesel. Lastly, since MB doesn't have to spend its capital on maintaining its engines like its competing manufacturing brands, such as BMW, Audi, VW, and Porsche, it has the extra capital in making their models feel more comfortable and technologically advanced. The reason I bring up those brands is because they priced around the same as MB, but they are very DIFFERENT.

[@jackb2676]

new wipers for My $8,900 SL55 AMG

[@LTG1930]

Probably mentioned before, but is the intercooler pump working, its a common failure and the car goes rich when IAT temps climb; you should see temps at 35-30 degrees over the outside temp

[@simonculmer6624]

Tavarish. Re you increasing Dyno readings on the SL55 with subsequent tests, when I first drove an SL55 in 2002 when they launched in the UK, Mercedes told me that the car offered adaptive responses in that if you drove it gently, the throttle and brake feel reflected this but that when you started to drive it harder that they they firmed up to match your driving style. At the time when i started the test drive the car felt quite soft but as we went through a spirited test drive it certainly started to firm up. I have had an SL55 for about 8 years now but it feels the same all the time (maybe I drive it hard all the time), hoever, if there was some truth in what Mercedes said to me in 2002, could it be that as you push the car harder as in the Dyno test, that it remaps the ECU to reflect. Just a thought, anybody know. Loving your posts on the Mercs, inspiring me to wrench almost every day Simon

[@BrandanVenne]

Check and possibly replace your spark plugs. And get some K&N air filters or Green Filters. Both made a nice difference on my C32 AMG. I would also clean the throttle body and reset the engine adaptations with a compatible scan tool

[@TheTrYIn]

From a German point of view you have pretty bad gas in the us... so try putting in 100+ octane gas and do a large service on it!

[@Freimopp777]

US and Europe calculate it in different ways which makes US fuel look like it has a lower rating.

[@John1Brady]

Check the intercooler water pump. Check boost level. Of course check air filter. Should make apx 400whp.

[@SMG707]

I love those wheels imo. they look period correct

[@d1sturb3d119]

Seems like the motor is pretty healthy! Good stuff. Well worth the money at that price! Just goes to show, a smart car guy is a happy car guy!

[@04dram04]

Price and prestige aside. Which car do you think is better overall. The Mercedes or the Aston?

[@toonames]

before doing a dyno run, change the air filters, the gasoline filter, clean the injectors, replace the spark plugs, and that numbers will go up... and if u can change the oil in the kompressor to last longer...

[@charmamillion]

And also he need to split the cooling

[@lukelane31]

Can you do an engine bay clean video

[@tavarish]

Sure!

[@phantommedia9964]

great! I've been wondering what's the proper procedure for cleaning an engine bay!

[@harryhazeel5974]

Check the intercooler pump - the original ones inevitably stop working and the supercharger clutch disengages as a safety measure.

[@SardonicBastard]

Change those air filters! Not sure how that particular ECU works, but a lot of times at WOT they are "open loop" so it's not using the O2 sensors. If there is some kind of airflow restriction, you'll get less air but the same fuel, and it will lose power and run rich.

[@peterj5751]

The drop off in power and increase in fuel ratios says to me it is starving for air, probable due to the air cleaner being old and dirty. Yu could have quickly checked for this by taking it out for a dunk run. Better still, Change the oil, plugs, leads and air filter and run it again.

[@ezale08]

Yeah, i'm waiting for the roadtrip video

[@SpicyEggroll]

man... 5 videos about this Mercedes already, I demand 5 more videos

[@acollicott]

Hey if you're looking for wheels, I have some AMG Monoblocks for sale in Philadelphia. They're from a W220 AMG package. They're staggered 18 inch wheels. 245 fronts and 275 rears.

[@BHobbieIowa]

Still a really fast and good looking car.

[@chasevineland1508]

Spec wise it should be 493hp at the crank. This dyno requires the wheels to be taken off but I think the usual 15% drivetrain loss is still relevant here. Hence multiplying 386 at the wheel/axel x 1.15 gives you a corrected horsepower of 443.9 horsepower which is damn good. Put in new spark plugs and air filter and you may be closer to 450 hp which is damn good for a 10+ year old car.

[@jospi2]

It's more like 455 hp now. 455 -15% = 386.

[@nightkil13r]

With the AFRs getting richer as the RPMS go up higher, i would first do a boost leak test, before looking at replacing anything. from the AFR numbers it looks like its not getting the air it expects according to the tune(O2 sensors, unless they are wideband, wont pick that up if its too far out of range) on the ECU

[@Blue-ur1ii]

Change the air filter, change the oil and the oil filter also

[@jospi2]

New transmission oil would also help.

[@TsunoOkashi]

I probably would have fixed the oil leak first, but that's just me.

[@zangovu]

According to Wikipedia: 500 PS (368 kW; 493 hp)@6100 700 N·m (520 lb·ft) @2650-4500 Accounting for estimated average of 15% drivetrain loss, should be 419 hp & 442 tq at the wheels. Seems like you making a bit more torque than average. 419-386(dyno#) = -33 hp, that's 7% down on power. 442-468(dyno#) = +26 tq, that's 5% up on torque. Actual drive train loss for hp: (386/493) = .782-1.00 = .217*100 = 21% Actual drive train loss for tq: (468/520) = .90-1.00 = .10*100 = 10%

[@portonathanial]

Zango Vu its an automatic! more like 25%loss

[@edward569]

your guilty of good content. automatic thumbs up bro.

[@JShih-in4nw]

a clean new airfilter, new spark plugs and lightweight synthetic 5w-40 might increase horsepower

[@migz817]

check your intercooler pump. a lot of us e55 guys upgrade to the Bosch 010 pump

[@bioshockzoa]

4:28 what is this thing at the left side ?

[@KostadinDelizhanski]

before change of oxygen sensors ... just change the oil and filters ... and also clean the MAF (air flow sensor) ... it could be a simple thing ... but save you a lot of trouble wondering why no faults are present and the car is a bit low on power ... fast, easy, cheap to clean ... then try oxygen sensors if there is no effect thumbs up for the video

[@jordanberry4824]

That's still a crazy sharp car and with the blower/supercharger it's badass!!!!!!

[@bayezitsalgur3818]

Was the car leaking, or did it seem like that to me? Visible after 9:18

[@roberthale8407]

The abuse continues if you did not change the oil, air filter ect.

[@jackallen6261]

I thought "oh man, your worse than me!" Yeah I would have at least done an oil and filter change, lol.

[@freeandresrivera]

I suspect a tuneup would be in order as indicated in the video. I also believe ambient temps would be a factor. NJ is probably hot and humid now. Maybe ice the intake?

[@wizardindustriesusa]

Your AFRS are probably off the charts, which is bad news for a supercharged M113k.

[@logan86123]

Surely those hub dynos are bad for the drivetrain? By not having the torque of the edge of the wheel to assist it's a lot of stress right at the centre. Or am I just making things up?

[@ms_enj]

Tavarish's biggest fan makes an appearance at 4:04

[@Drtbiker88]

the numbers are jumping because the coefficient of friction is decreased due to the warm oil every time you run the dyno. I can bet that power will increase when you change the oil because I can bet the oil in there is the wrong viscosity- keep those piston rings happy :)

[@MrTetedefouine]

Love the " you guys need to wrench everyday " 🤘

[@annieworroll4373]

This makes me want to take my Grand Am and get it on a dyno. Results like yours would mean a broken dyno, still, it might be fun to know how close to spec it's running.

[@toonames]

please do that dyno run again with the engine in perfect shape

[@SamAbraham]

380 to the wheels doesn't seem bad at all

[@AMGmeister]

He needs to replace his I/C pump, the stock one goes bad. Car should make 415-425 whp stock.

[@SamAbraham]

AMGmeister for some reason I processed 380 as 480... Totally forgot these were already at around 500hp. Makes sense

[@PANZERSGARAGE]

AMGmeister haha glad to see you here my dude! 😎👌 love your videos on the w211

[@SamAbraham]

AMGmeister speaking of W211s, I'll likely be getting an E63 soon. I'll have to check out your vids!

[@AMGmeister]

Thanks!

[@kickblake]

It the motor revs at all past 5252 rpms, your hp should exceed your torque. I wonder if the air filter is clogged, and it just can't breath? Would explain the richness too.

[@PANZERSGARAGE]

Tavarish stock at the dyno. 400 ish and 470 tq is a healthy motor. your ic pump might be going dead. plus a tune up and coolant change.

[@EvanAxer]

Just had to say thats a dope AE86 in the background

[@Hack_es]

Did you already change the Plugs, and all the fluids? Could make a noticeable difference.

[@fsb1284]

Not going to get into driveline loss debate, but I do wonder what new Mobil 1 Synthetic, plugs, coils (assuming they're needed), and air filters would do? My standard M113 in my '02 S500 jumped ~3MPG city and hwy with its 100k mile "tuneup", which I did early due to age at ~90k mi last year. Seat-of-pants power improved too 👍 Not gonna dyno a 4000+ lb limousine 😂

[@komtgoed8330]

Great video! I'd like to see how you're going to get it up to standard spec!

[@TitaniumCountess]

Ouch, re: power. I think you need new plugs ASAP. And possibly O2 and MAF and air filter. Another thing you need to check immediately is whether or not your Intercooler Pump is working - that fails very often on these cars, and there is no warning from the computer, or any check engine light if it's failed. Way to test it is hook up an OBD2 scanner to it, and while it's hot, monitor the intake air temperatures. If it's over 140-150F consistently without hard driving, your intercooler pump has failed. You need to fix it ASAP because, one, the supercharger will not run when temps are that high - it will engage and disengage immediately...A stock M113K/722.6 engine/trans combo should be putting out at least 400HP and 450TQ to the wheels... My stock 2003 E55 AMG put out 412HP/467tq to the wheels...

[@MOBAutoBoutique]

change to the bosch 010 pump and put a pulley, tune, and headers on it!

[@bjk311]

great buy man and can't wait to see tune up and build. best of luck

[@jeremiahguerra8603]

4:30 What is that in the bottom corner

[@Pleasiotic1]

Are the original HP numbers based off of the old net rating system? In 2005 everyone switched to the SAE standard (J2723 iirc). If the OG numbers were Net that would probably explain the discrepancy a bit.

[@cheechychongs3450]

I love your videos man. Awesome cars for awesome prices lol

[@emmexfyv]

Cripes that Dyno looks like it would be a pain in the ass to use.

[@Zepherian]

My guess is it needs a service, a tune and I'm not convinced the engine is getting enough air also on that crappyish dyno setup. With a few more dollars it will be 95% the car it was new. I like these, agreed they're the prettiest SL. Even messed up it's nigh on a 400hp car. How much was it? :p

[@OMGWTFLOLSMH]

This car will forever need "a few more dollars".

[@azmike3572]

Someone should define "a few more dollars" for this car. Hint: it's always "add another zero".

[@brandonblair6868]

There is fresh oil in the engine before your run right?

[@davidkrueger3227]

The "power loss" you are concerned about seems normal considering that you are driving through a torque converter, automatic trans and differential. I bet that car scoots with that nice flat torque curve!

[@MarkKoolen]

They starting up the fan "lets walk with a sub woofer enclosure next to it" :D

[@000guruzinho000]

4:25 -4:30 GIANT SPYDER left bottom corner 😮😮😮

[@brapbrapbrapbrapbrapbrapbrap]

Tavarish I had a feeling you were at wired from the thumbnail. central jersey represent!!!

[@THEIIVADER]

Not bad for the state the car is in. If you change the oils, filters etc. and give it some good runs, I think it will pick up some horsepower. It was used as a boulevard cruiser so the engine is probably caked, one hint for that is the gain in power when it got some beans on the dyno. Still an incredible car for the price, with so much potential. Keep us posted and nice vid.

[@rowdy0190]

My 2006 E55 has a 180mm blower pulley and makes on the dyno 440Kw and 1000Nm of torque or 590 hp

[@r6vince164]

FYI, HP=torque*RPM, if torque curve looks right, then HP curve is right

[@AJGreen-cn8kk]

damn it, after watching your videos of this AMG, I searched all of Craigslist for one. Found nothing under 15k! You sure got a smoking deal. I'm really excited to see what you will do with this. The costs kinda put me off. I've backed out of two deals in the last month. one was a 97 sl500 and one an 01 E55 AMG. both even trades for my Harley. maybe your experiences with this AMG will be my motivation.

[@omarawad2161]

Honestly, I think there's so much more wrong with this car than what he has shown. On top of that, he pretty much bought this from someone who could care less about cars it looks like. This thing was abused to the max, which is probably why it's dirt cheap.

[@metparker]

Factory measures at the crank. 493 from the factory is about 395 at the wheels

[@sivanusiva3641]

Shoutout to the white ae86 and the black mr2 @1:14

[@greg4501]

you put premium fuel in it?

[@tavarish]

Of course

[@greg4501]

Tavarish hey had to ask lol oil change and tune up would be where I started. run a Lil seafoam threw it

[@Justin-ul9wo]

Is that power corrected to a more common Dyno measurement?

[@LordJesusIsGodAmen]

I would imagine the power went up after the first couple of runs blew some crap out

[@teamsleepnine]

maybe after major service,fresh plug,oil,air filter it will give a little more hp?

[@slasher9883]

Here's an idea for a future video. Everyone here is saying you should have changed the spark plugs before the dyno run. So do a video of you changing the spark plugs on this car. ALL 16 OF THEM, MOST IN STUPIDLY DIFFICULT TO REACH SPACES IN THE ENGINE BAY, WHICH IS SO TIGHT THAT YOU CAN BARELY EVEN SEE THE PLUGS LET ALONE SWING A WRENCH IN THERE TO RELEASE THEM FROM THEIR ABNOXIOUSLY LONG THREADS. Then tell us how you love your M113 engined mercedes afterwards. Oh and they are platinum, so you are looking at least $180USD for a set of plugs. PS- I own a M113 engined Mercedes, and I love it :-).

[@mindaugasrimdzius5463]

So you went on dyno without oil,sparkplugs or air filters change and wonder why its underpower?Smart..

[@redbullo560]

Damn you parked perfectly parallel to that white parking spot line, that amazed me :-D

[@GeoD7788]

I just found your account, and I'm loving these videos. Awesome venture.

[@dereinedahinten206]

[@Epd3mik]

I like those videos! Keep it up! :D

[@eduardsmetana8857]

Well technically, 360-370whp sounds about right for this car. If you factor in that its an early 2000's mercedes with an automatic, 25% drivetrain loss sounds reasonable and 493*0.75=370 so its actually really good considering the condition of the car.

[@Adonis909]

We have to see the straight pipe, you look old school and keep things oem but damn unleash this v8 to its true glory.

[@jmodic]

Isn't those hp specs from the factory crank and the wheel is typically about 15-20% difference? I mean know there not an exact science but that is true it is doing pretty good, right?

[@Renesis97]

That AFR... couldn't it be the air filter clogged?

[@alexarias44]

The reason it picked up horsepower after the cooldown was because it wasn't heat soaked. The M113k heat soaks its ass off.
