Here's Why The E55 AMG Is Still A Relevant Euro Super Sedan. New E63 AMG Power With Easy Bolt Ons.

After doing a bunch of big power modifications on my 2003 Mercedes-Benz E55 AMG it was time to hit the dyno for a remote tune from Tony at Race iQ. After gaining some nice power with the new mods, I was surprised to see that one mod caused me to actually lose horsepower. I think I can make some changes to gain it back though so comment down below how much power you've made with your M113K powered AMG Car.

Scroll down the page to "preferred customer" and click "learn more" to get the deal!

I go over the mods in the video but if you want to see me install a smaller supercharger pulley, larger throttle body, a water/methanol injection system, larger Heat Exchangers and more than check out my E55 build playlist below.

How much power does your M113K Mercedes make? List power mods.

Good to see the E55 again! I'm glad you don't get too caught up in dyno numbers like most, consistency is the key... as we all know from back in the day, the street is the great equalizer! The most important mod is the driver mod, that's how 500 HP cars can end up walking 800 HP cars.

Boost varies a lot depending on IAT's since there's no boost regulation in those superchargers. I've even seen up to 13psi on the stock pulley on very high intake temps. Realistically the stock pulley makes around 8 or 9 psi, and the 77mm pulley makes 10 to 12psi. Spikes slightly higher during gear shifts.
I personally think the engine becomes pretty knock limited after 15psi, but with your setup with the water/meth and headers you should be fine with a few psi above that. Really like the build so far. Looking forward to see how much more you get out of it!

Those pulls in 3rd gear are huge and the look of your car makes me wanna buy an e55.

[sethfrancissimracing]

Shots fired #Tavarish 💥🔫💥🔫 1000 hp guaranteed!
Haha, that was pretty funny.

[FLPLASTICSURG]

Unique, practical, professional and always entertaining! Thank you for your efforts!

[staxxafool]

You should see if the guys over at Weistec will hook you up with a supercharger!

Finally another E55 video! There is a video on here of an 05 I believe, doing a 4th gear pull (don't remember the mods) that hit damn near 200mph.

[timek]

The stock pulley car made 492hp 518 torque, 83deg weather 4th gear 160mph with 306 gear. 498hp for race gas. 122mph traps. at track.

You really need to get rid of the stock exhaust. Less restrictions can only mean more power.

Awesome video Alex, thanks much for rep'ing RaceIQ Performance, guys make sure you take advantage of the discounts given via LSC.

Cant wait to see more from you in the near future 👍

[akkayalogistics]

E55 is a beast. Love the stance and look on them.

Hey Alex. Thank you so much for doing the no-wmi vs wmi dyno runs. Plenty of data on its effects on post-blower IATs on these cars, but I think you're probably the first to test and document this on a dyno (or drag strip). Can't wait to see what kind of times you run at the strip.

[ryanmccormick]

Your E55 is a really cool car! I'm not surprised your almost at 100k subs your channel is excellent Alex I'm sure you'll hit 1 million subs in the not too distant future 🙂👍

[StoneCoolds]

LSC one of the few channels that you give it a like even before the video starts, quality its quality xD
In a few months im going to gather courage and mod mine and i will send you the numbers :)

[gtobob]

15% off? Man! This cheap Serb can't wait to get my dialed Yugo on the rollers!!

[Dailymercedes]

That’s some good numbers I have vrp primary HE and secondary, 76mm pulley and tune, bwk, I made 460 wheel and 560 torque soon to get longtubes to reach that 500hp mark!!

[sergiowolfpac]

Ayy thanks for the race IQ tuning discount!

The issue is any small drop over a grid on the left hand side front (near side)there is a bang and my dash sounds like its coming out but the rear feels bad on the left also. its like the rear left has more travel down pot holes and the right is solid. on the right hand side driver side it always feels solid. really don't no what to do I have almost rebuild this car underneath at the cost of 15k. is their anyone in the uk that could maybe shed some light. what is your thought alex please help or going to end up selling it because its p$%%$%^ me off but I love it to much its like having a beautiful girlfriend that you know is bad for you.
