Has anyone on here installed one of these on their E500? I'm considering the Evosport setup but wanted some first hand feedback from people who have installed one.

Here's the one I'm considering:

Website states up to 12hp, but on our N/A V8's, I'm not buying it.

Anyone?

I personally did not have good experience with underdrive pulleys, on my M3 and from a different tuner on my 540i. The car will run hotter in the summer(hp loss because it is running leaner) thus the cooling fan will be on most of the time, which equals to the alternator being on all the time; therefore it equals to big HP loss all the time, since the alternator is trying to catch up with with charging the battery. In theory, there is a small gain at top RPM, but in reality there is a big HP loss, unless you are constantly above 2200-2500 RPM. Now think about what RPM our cars are at most of the times? If anybody designs a 10-15% reduced crankshaft pulley, on a naturally aspirated engine, I will definitely try it. I hope this will help.

plus if you run an aftermarket sound system or even just a set of subs the alternator wont be able to keep up with the load and youre going to have a lot of dead battery issues

Yeah, I certainly understand that a cheaper setup could, and probably has caused problems for people in the past, on their past cars. I'm specifically asking about the Evosport setup on an M113 engine. I can't even count the number of W211 E55 guys who have them on their cars with no problems. Even though E55K's are on the M113 platform, we all know that they're more than a tiny bit different.

From what I can tell, Evosport is one of the best in the business as far as pulleys go.

So, nobody with this setup?

well while i have no experience with evosport so im not knocking theyre products by any means i have run unorthodox pulleys in the past,which in no means are of low quality,the concept is basically the same slow down the accessories i.e alternator,water pump,p/s pump in order to reduce parasitic drag on the crank thereby freeing up a few ponies.

From my experience, aside from product quality, the one area to be cautious about with aftermarket pulleys is that they turn the alternator and waterpump fast enough at idle so as not to discharge the battery in traffic on a rainy night and/or cause the engine to overheat in traffic on a hot August afternoon. Provided these items are sorted for the M113 engine, I would estimate about 5-7 HP, but every little bit helps.

You just might end up with a record for the fastest NA stock internal E500 at the rate you are going.

If I still lived in Maryland, I think you'd appreciate the new toy I picked up last week, not a Benz, but a better package vs. C63 for the same dough. I can't wait to see what a pully change will do for it after break in.

I think I may hold the record already (13.49@102.5). Not that it's fast, it's just that not that many people really do HP mods on these things. It's just so expensive for not much gain. It's so much smarter and cheaper to go with a stock W211 E55 than mod out an E500. But I've never been mistaken for anyone smart or cheap.

Anyway, just hung up the phone with sales at Evosport. You're pretty much on target with the 6-8 RWHP gain from the pulley setup. So, it's $379.00 + 3hour installation ($300.00) = 679.00 or so, for 6-8 RWHP. Or you can do the install yourself. But efff that, it's 9* outside right now.

This is why I'm the only E500 on dragtimes.com

Car goes in for secondary cat removal and x-pipe installation tomorrow.

More on this, please.

surprise no one has done this mod yet

Benz-O-Rama

Good to see you around, David. Are you gonna become a sponsor here, too?

For those that don't know, David and D.C. Designs are the ones responsible for the current look of my car. They did a great job on the AMG conversion and painting my roof black.

Still get compliments almost daily.

13.49-----What is the car supposed to do stock?

Benz-O-Rama

It's like 14.10 - 14.20, depending on which magazine you read.

buffyclk500

i have the pulleys on i feel no big hp but 4 only 350 it is not bad but just so u no they r a bicth 2 put in

MB211

All I see for mods is ECU tuning and mufflers----you are telling me you shaved 6 tenths from that?

Benz-O-Rama

Yes sir. I ran a 14.10x @99 at the very same track when I was stock. I have a timeslip and many forum members were present during both runs.

Let me know if you want me to post it.
