Thanks everyone for the interest... I am waiting for the pullies to land here in Toronto so I can figure out our cost..

I'll post pricing as soon as I receive them.

The water pump pullies are already made and waiting..

Jangy: Sent you PM re: TB.

jangy

Got it and replied. My thread on a GB was shut down, since I did not follow procedure. I will try to get one up somehow, or people can just pm me if interested or I guess add to this thread.

Sep 05 build ... ASP / extra heat exchanger / VRTB / SC Phenolics were in place for some time (mbe 6 weeks) before I had tune done. Tune was Wetterauer.. VRAB was added after tune - but is currently off the car while getting its service.

I suppose the extra bits were able to use the ECU tune more than just the ASP on its own ? But I dont think massively more ? Only the VRTB would affect the power immediately available and not sure how ecu blends with the VRTB ?..?

Yes...please...we cant wait anymore...

Guys.. one thing everyone should be uniform on, and that is how pulley diameters are described and compared..

The ASP pulley is 175mm belt groove to belt groove.. It is 178mm LIP to LIP. The lip is 3mm all around and is raised so it holds the belt in place.

When you are comparing crank pullies, make sure you are measuring the same thing.. the only real way to compare them is groove to groove, because each crank pulley might have different variations in lip height. Just $0.02...

Sorry bro...didn't mean to hijack your thread.

Consider the rest sold. I can easily get 3 people from here to hop in.

Of the people that signed up, how many are in SoCal? Where do you plan to do your installs?

Does anyone know a good source for the Jaguar belts?

I got my Jag belt here.

Fits perfect on my ASP.

So are you telling me I should have sent 15 to California then.. lol..

Hardware

What? Im on the wrong coast?

vrus

LOL.. No.. no.. I meant I should I have sent more state-side than I sent to Canada..

Hi guy's I'm new to this site and just purchased an 04 E55. Interested in the pully also but wondering how much boost this will add and what else do I need. Looks like that belt for the jag will work for this pully? I had a ford lightning before and did a 6mm pully,cold air kit,and reprogrammed chip and the truck went from 14.10 to 12.98 with no tire changes. Was hoping to do the same thing with this benz but need help from you guy's for direction. Thanks C.

By the way I'm in Chicago Il.

Welcome!!!

This pulley is 175mm rib to rib and will provide +3psi boost.. I wouldnt recommend you run this size pulley without cooling upgrades.. It will generate way too much heat and the performance of your car will be worse than stock once it heat soaks.

If you want to jump right into a big pulley you need to do the cooling upgrade kit at the same time to keep IAT temps in check.

cgutowsky

Ok thanks where do I get the cooling kit and what does it come with?

vrus

Sorry it took me so long my kids keep asking me questions That kit looks great but before I get it I need to find someone out this way that can start working on this thing, do you know anyone I can contact? And 3lbs of boost is that it, I added 6lbs to the truck and never had any heat soak issues. You said this was a 175mm pully, but I thought you wanted a 178mm? Can you run a smaller upper also or will this car not handle that much boost?

vrus

Talk to Sunil @ Motorwerks.. He is an authorized installer and distributor for my stuff..

He has 2 install facilities; Michigan & Houston and also does remote installs.

You will find out that these cars are quite different than what you are normally used to. Heat is a major issue in stock form and adding bigger pullies just makes things alot worse.

178mm is the measurement from lip to lip.. 175mm is the actual pulley size measured from rib to rib.. Some people just measure the outside diameter in which case you are getting lip to lip measurements.

jangy

Do your research and decide what you want. This particular sized pulley adds about 3psi. There are also smaller ones out that give about 2psi. Either way, cooling upgrade will be the next thing you need to compensate for the added heat you are generating. The options are: Just upgrade the factory pump, add a larger HE unit AND upgrade the pump, and separate the cooling systems AND add a new HE and pump.

Whatever you do, get them to wire the pump to remain on all the time. The OEM ones had a short life and rather than address it, MB simply had the '06 and newer ECU flashes use the pump less, which raises our heat.

jangy

Keep in mind that we are running 12psi as it is. Raising that to 15psi makes a difference. These pulleys get to a point of diminishing returns and loss of practical advantage with size. For example, just bumping the pulley slighty gives you 2psi, but then you really have to go bigger to get just 1 more psi out of it. Then, it becomes an issue of the TQ that the belt must hold. It will end up slipping, etc if the setup can't handle it. Last thing, the 178mm is about as much room as there is. VRUS also takes advantage of shifting the water pump pulley size.

Some in the past have tried playing with smaller pulleys on the SC, but I have never seen success. Something about it being so integral to the SC clutch that it caused issues. I'm sure there is something to it, but nobody has bothered ripping the world apart there, yet.

cgutowsky

Alright thanks so is that the biggest lower pully that guy's are running? And if so is it because of clearence or is that all the more boost this motor will handle?

jangy

It is the largest that we can get. It is that size, due to literally fitting inside the face of the motor. It is NOT because the motor will not handle more boost. It is just that you have gotten to a point where the pulley would have to be HUGE to add another psi. That is what I meant by diminishing returns. A larger pulley will simply have too many side effects.
Don't confuse that with the car's ability to take the power. It can. The drivetrain is exceptionally strong as compared to typical cars. Many have run NOS and that should prove that the drivetrain can handle more PSI. I just think that we have maxxed out the Crank pulley. Even a smaller SC pulley would only make that extreme differential bigger. Sort of like a ten speed. You don't want to be in the big ring up front and little ring in the rear.

cgutowsky

Sorry you answered my question when I must have been typing. Now it makes sense I wasen't awhere it was making 12lbs stock. OK i'll take the pully if I can still get in on the group buy. I have paypail just let me know when and where to send it, Thanks for all of your knowledge and help.
