"MB design 20-25% slip with current design." Wow! They actually did this on purpose? Can you imagine the pulley doing burnout's on the belt? Yeah why not! belts are cheeper than s/c clutches hey. Now I finally understand MB's genius methology on saving the supercharger and clutch system.

In regards to the clutch slipping I had the same theory that loss could be occurring in this region as well so I locked up the clutch electrically and marked where they join, then in dyno mode I ran it through all the gears flat stick.

Surprise Surprise... No Clutch Slip with the proto wrap, aux tensioner and a 175mm pulley. It's only a matter of time before the second gen clutches have been street tested. I looking forward to feed back from the 20 or so happy campers.

Yeah cool, PM me your phone number and we'll organize to catch up on my trip.

Lysholm style compressor air pumps have been around long before MB decided to get their mits on them. The actual rotor length is designed to flow enough air to fill our 8 little pot holes. Volume is determined by rotor length and pressure is dictated by outlet size. After pulling apart the gear house and removing the rotors I noticed that MB have used massive high speed bearings and shafts which I'm quite sure it can handle all the extra stress.

An interesting s/c FAQ link with lots of info on engine wear and longevity: http://www.hi-flow.com/HP4FAQSuper.htm

"Extra pressure to clutch packs cause overheat and failure" I'm yet to see a case. Do you know of any 55 clutch failures that have been published? I would be really interested to see a burnt out solid steel clutch.

Fight ???... Who is here to fight??? I find solutions to real world 55 problems through free thought and critical inquiry.

Guys chill a bit on the (this guy is a fraud) and give him a chance. He is new to the forums and by his own words says his English is not one of his strengths.
If he came on and said it was crap and gave no explanations, then by all means fire away. He is new and might not know the humour that we have on these forums & might been seen differently.
I really enjoy going through these threads and seeing the work of such great men and how they transfer their knowledge and expertise into our cars.
I am sure we are all car enthusiasts here and it is work such as this that helps us reach new plains of understanding for our cars.
Peace out

Just got the kit in today V!!!

Thank you so much!!

Can't wait to install!!

Hey Jim,

Mine is coming this week. Let me know how things go on the install so I may share with my MB Guy.......

Good luck......Are you planning on doing a pre and post DYNO. I know there should not be any HP gains so it may be a wasted DYNO expense.

You should not see choppy lines above 5K rpm. In addition, your A/F ratio should not fall off the charts around the same point. I highly recommend a post dyno..

hey zod, if you dont know, you dont know!

Thanks Vic,

The package arrived safely. Looking forward to the install this week.

I love all this cutting edge stuff. Why aren't we running chains and locked SCs anyway? This belt crap reminds me of the days that timing belts popped left and right.

Jrocket

Chains? As in timing chains?

jangy

Haha!! You know it. In all honesty, I do think that MB designed the belt as the weak link. I'm all into getting the most out of these things, but I do worry about adding tension. I definitely believe that these belts slip, but I'm just worried that we will end up with a new weak link if we lock this down.

chiromikey

this kit appears to be designed to reduce slip by increasing contact area not by adding pressure. with the proper size belt i can't see this system adding any more tension to the s/c pulley than oem...but wtf do i know compared to the knowledge and experience chatting in this thread?

Venom-AMG

Got my kit in the mail today. Now I just need install instructions. Anybody?

jparch

it does add tension to the system, did you not see the picture of the tensioner that finny designed to go with it also?? you could wrap that belt around 300degrees and if there is not enough tension it will slip; no slip = more tension.......

rflow306

The tensioner is a separate piece, you can run the kit with-out the heavy duty tensioner. It will still work good with the factory tensioner spring because of the increased belt wrap.

Jakpro1

Nah, being lazy on this one. Plus having massive belt problems so I really need to swap out the pullies and then the crank pulley asap.

chiromikey

there is also a new secondary idler pulley. so now instead of adding tension in one direction to significantly push against the s/c snout, you have two pulleys adding tension in opposing directions. so yes the belt is tighter around the s/c but the net force against the s/c snout would not appear to be signifcantly increased.

*maybe we're discussing two different things. i'm talking about tension against the s/c snout and i believe you're talking about belt tension. like i said, wtf do i know...

higginsbeach

Will I be the only one running the complete set on stock Pully's? I am not doing the pully upgrade until I complete phase I......

Roland

Noisey as all hell, I suspect. No quite an MB image thing.

Finny

Just to clarify a few items...

The added tensioner is spring loaded and is tension adjustable so it actually moves with the stock idler. It supplies some extra tension to the stock s/c idler not locking it up.

There is a new bearing supplied with the kit which is wider than the stock combined idler pulley to strengthen this area. (the one with the accessories and s/c together)

A slightly larger pulley is added to the s/c idler to help gain more s/c pulley foot print area.

The belt supplied is the new Gates fleet runner which is used for large trucks where gates claim 30 to 40% extra life span over their stock belts.

Reinforced, No slip and Longevity! to help efficiency and maximize potential power. Thats the whole idea.

If any one has any install questions, throw them my way.

ROCKETW19

does adam have you phone number? he will be installing mine on wed. and i think he has one gettin installed right now.
i will be great advertising for this product cuzz my dyno looks crazy at high rpms. i will do a before and after to show this does or dosnt work. witch im sure it will.

vrus

Guys.. Just wanted to add that I am polishing up the install documentation.. I did not want to hold up the boxes from going out so please bear with me while I complete the installation instructions.

Adam @ EE is doing the install for Michael's car and has a preliminary copy of the docs.. Once they are cleaned up, I will post a link for all of you to download.

Jakpro1

So far so good on mine. Pretty easy install so far.

I am trying to do it without taking out the fan so my arms are paying the price, but real nice setup Fin and V!!!

Was hoping to have it done tonight, but just too burnt. Hopefully Tuesday.

Finny

Thank's, glad you like it.

You must have small arms to get in there.

AdamG@NorCal

Update:

Michael's E55 is coming in on Wednesday for the V.R.P Xtreme Belt wrap kit install.

Will give updates on Thursday after dyno.


Cheers,

Adam

PS: So far the parts are well constructed. Kudos to Finny and VRUS.

Finny is the gates belt the Micro-V series belts ? I cannot find the "fleet runner" series?
