i recently ordered a AMS crank pulley and tubular manifolds for my sons M113 engine. after ordering one of his friends told him that he heard all kinds of mixed reviews on his products. nobody has complained about the quality or service but they question R&D process and effectiveness of parts. this is info from benzworld. i have knowledge of more of the USA vendors. give me the facts.

I have the AMS headers on my clk55..... they are good quality and the car put down 415RWHP with a kleemann blower.... with all 4 cats in place...... they do make power.
I read some old threads about a harm damper having issues.... but I don't recall the mfr.
Good luck in you search.

I bought my ams crank pulley used with about 7k miles on it and since then I have put 13k myself. My e55 is my daily driver except in winter. When I bring it back out in spring I'm going to add the evosport underdrive pulley kit which is supposed to work real well with the ams.

Blackbenz - theres a guy who did the swap in his cls500, and he ended up losing some options due to wheel sensors and computer swap..... no lsd, no cruise control, etc.. Not sure if there is a way around all this?
If there is a way to keep all the options I'd be all over that option as those motors are coming up more and more these days.

powerplant swap
the engine, trans and wiring harness came from a 55k totalled rollover with 11k miles. i spent almost 19yrs at the santa barbara mb dealer who also handled bmw. audi, porsche, jaguar, rover and infiniti. it was a 7 month job even with the help of the shop techs. i had a vast knowledge base of help. some have since left the dealer and opened a specialty shop in santa barbara doing the same sort of thing for the public. wont give details because of sponsor conflicts

AMS pulley
i recieved the pulley via air mail. header are coming by ground and a few days behind. service and communication from ams has been good. Pulley is a very well machined item, also very strong. hard to imagine that this piece as light as it is will be as effective as the stock item thats so heavy. this weekend i will take it out to a local race shop. i am lucky to be a couple miles from ALAN JOHNSON RACING who runs the ALANABI NHRA team who dominated this and many previous years in both top fuel and funny car with various sponsors. blaine his brother a top fuel champion was killed a couple years ago. they will spin this thing up to 10k and see what it does. i wonder. these mb cranks are forged and a forged crank will flex more than a cast crank because cast will just plain give up and crack and forged distort/flex. being a ex roadracer i know the dynamics of rotational weight. remove a factory bike alloy wheel. replace it with say a marchesini magnesium replacement. 8 lbs lighter. a bike wheel at 100 mph, each pound removed from wheel is 16 at that rotational speed. a 3-4lbs lighter pulley at 6k is generating big numbers

AMS order
headers arrived and also look very well made. so far very hasppy with transaction totally. pulley spun to 4800 and held true with no balance or runout issues. engine does not spin to 10k and he did not have the proper fixture, so pulley was not spun to excessive speeds luckily because the manufacturer agreed that no need to spin it out of its normal operating range. headers are just plain nice pieces. good welds, beefy construction, smooth fit and very appealing to the eye. left flange was a bit hard to get seated on the manifold, but thats the alignment of the exhaust with everything in place. next step will be finish latheing out a billet 2mm undersize waterpump pulley and start engine. more info to follow

WRONG
takes more power to get a heavier object than a lighter object to spin, even though its diameter is not as big as a motorcycle wheel and have a hub portion of the weight and outer rim portion. the pulley is all close to point of rotation. very basic.
you will also loose a minimum of flywheel effect in turn allowing the revs to return to idle quicker because the rotating mass is not carrying the rpm and will slow quicker. less mass, less inertia. power increase may be minimum but the delivery characteristics will change.
