AMG E Power

@weistec, I know you say it has ran on the m156 with no problems but this is the m113K.
how many miles/hours/years ?? have you tested on a E55 AMG with a stock supercharger ?

Weistec

This was discussed earlier. It has been ran on many test cars for years and countless miles.

Aside from price as theirs seems to be more money with the tune being part of it. What would make this a better setup than say the one ams offers? http://www.amsperformance.com/cart/a...e-upgrade.html

Just two different ways to skin a cat? genuinely curious.

AMG E Power

good to know ! last thing someone needs to worry about is the pulley coming off and damaging the crank shaft. u guys have instagram and youtube videos, would be nice to see some e55's using the pulley on youtube or something

V TO E55

How does your 170MM pulley compare to let's say a ASP 172MM?

cij911

2mm different

V TO E55

LoL...I could count

Just wanted to know how the compare since this one is lighter then a stock balancer etc.

Wanted to know if it mite need to be retuned if swapped from a ASP172mm to the 170mm pulley

cij911

LOL you never know on these forums...As for needing a retune if you change the diameter of the crank pulley, you should know the answer to that too....But you could always install it and just look at your datalogs, since I am sure your have a wideband and datalogger.

Anyone running one of these yet? Feedback, opinions?

Weistec- Will I need larger injectors to run your 170mm along with the smaller S/C pulley?

HB_Steve

I have ordered the 170mm pulley and look forward to getting it installed soon.

V TO E55

I have the 170mm with a smaller clutched pulley...I used to have a 172mm ASP pulley with the same set up...it's deff a little slower then the 172mm but for some reason the s/c engagement is more rougher then my old 172mm pulley..

I mite try to order the 180mm ring from Weistec and see if I could get the power back but scared about the harsh s/c engagement cuz it's very annoying during daily driving..

I love the look and quality of the Weistec 170mm pulley plus the ability of changing pulley sizes quick

Any more reviews on this I'm about to order this deciding between an ASP 172 or this 170 stepping down from a 77mmFSP/175 ASP because of over boosting. My new combo will either be 172/ 83clutched or 170/83 clutched or should I just do a 180 and be done with it. A lot of people believe even that's too much for the stock blower. I can keep it running cool enough (KC/trunk tank/meth) but don't want to break another keyway or piston.

Weistec

We have many customers now running our modular crank pulley with great results. In terms of breaking a keyway, it is very common when spinning the supercharger at high RPM's but this issue can be completely illivated via our crank pin kit.

Not to mention you also get the fluid dampening technology that isn't offered with any other crank pulley system. Let us know how we can assist. Thank you!

Thanks guys I'm definitely going to pin it. I guess I'm wondering about the benefit of pinning an oem style (ASP) vs your fluid dampened. Also figured out I sheared off the two locating pins on the blower snout, this last setup really did a number on my car!

What is your opinion on injectors with your pulley?

smartyin

i was making decision between ams and weistec pully. but finally i placed order to weistec because seems weistec guy more dedicate in their job..

i hope here some people can educate me what is the different between ams& weister pully in design...

anyways,i just placed order for 180mm and tune. hope to get it soon. and very excited to see the result.

and does this kit work with 3.0L superscharge? i consider to update superchrage later..once my stock goes bad.

I'm running the Weistec 170mm crank pulley. I've done about 3,000 kms on it so far with no issues at all. The product looks good and I have no reason to doubt it's quality. Also nice for those wanting to experiment with boost/different sizes as you need only switch the outer ring which is secured with ARP bolts

ajm55

I'm running the Weistec s/c with their 170mm crank pulley and 62.5 mm upper pulley. Boosting just over 17psi at 5,500 feet above sea level. For you more fortunate guys at the coast, a less aggressive pulley combo would do the trick.

smartyin

bro, can make some video??

TheTherapist

Really nice looking part though I echo what other forum members have asked - is there any chance of a video showing the pulley in action?

smartyin

do you guys order the crank drill tool and keyway from weistec which cost extra $100?

i have no idea how to use this tool and keyway, seems it is a big job for this little parts...??

ttt! both myself and AJM55 are fighting issues with shredding belts with this crank pulley, mine is on a stock SC with a clutched pulley, his is on a weistec blower with a fixed pulley.

Did you guys experience any issues shredding belts in your testing? what should we be looking for to alleviate this issue?

anyone on the board running this crank pulley successfully with out shredding belts? Trying to diagnose here, nothing more...

johnny_b

I recently purchased a weistec crank pinning kit does anyone know if it will work with my 180mm asp cp? I called weistec and they don't know if it works with other pulleys besides theres

AMG_55_cruiser

There is a lot of talk about these. Did any of you who went Weistec route need to change your injectors to help compensate?

These have been out of stock for almost a year and confused if there are issues and thats why they aren't offering any longer?

Thanks

spastik monkey

Would also like to know when these will be restocked.
