Would anyone like to see a group buy for the Eurocharged / LET 172mm pulley kit?

What would the ideal price point be?

jangy

Can you give some details on it? I'd be interested because i'm not sure i like the huge 180 because of some lag. Also, I've seen plenty of tuned E55s with smaller pulleys put down great numbers.

Anything specifically special about this other than size?

---from thread----

First pass with 172mm & Johnson CM30 installed and stock tune:
SAE Corrected: 418.45rwhp 443.17rwtq
Uncorrected: 423.96 449.01rwtq

After 3 more tunes to get it just right the end result was:
SAE Corrected: 470.97rwhp 498.23rwtq
Uncorrected: 479.27rwhp 507.01rwtq

Crazy numbers....

I am enjoying my 175mm pulley and LET tune. I am curious what the difference would be with a 172.

You guys are in for a treat! I have been running the 172 for about a month now and it puts down serious power. It does not wobble at all and provides the same power as my old asp, but with less wobbling!!!

It also looks kick a$$ in the engine!!

Thanks again to let/eurocharged for all the help and great products!!

jangy

Any drive impressions between the larger asp and 172mm? Do you know weight difference between the two?

aleksandar1099

Hey Jangy,

To tell you the truth, I did not notice any lack of power changing from the asp to the LET one. I will be upgrading to the big daddy 180, and the power change will be noticeable with that one!!

The car drives very smooth with the LET pulley, but it also drove nice with the ASP, no drivability issues at all...

jangy

I believe that a smaller pulley can put out as much power, especially as we leak boost.

I'm curious if you notice any quicker response from the motor with a smaller pulley. I have the VRP 180 one and noticed from day one that the larger pulley was causing some lag in initial acceleration. Once spinning, all is good and the boost helps. I just wondered if you noticed anything?

So, if you are going to a 180mm again, then why do you expect more gains out of it than the ASP?

aleksandar1099

Because I want to have the fastest e55

But seriously, I think that with a proper cooling system the power of the 180 can be had without issues...

EDIT: I did not have the 180mm asp, I had the older design...

jikjak

i didnt realize that the 180mm would cause more lag.
if the smaller pulleys can make as much power as the larger 180mm then what would be the optimal pulley size?

i have the 168mm now but i would like to make more power. im just not sure what size to get anymore. i just assumed it would be ideal to get the largest one available (after cooling upgrade of course).

jagass

I'm pretty interested here too...

E55BKS

Count me in, but don't we need the tune with this pulley?

E55Pilot

And once again Not even Jangy understands what he's typing....

Seriously WTF does that mean?

jikjak

im just brainstorming, but i assumed that it meant that the 180mm makes more boost than a smaller pulley but our cars leak excess boost so that increase in boost is not able to be used?

i remember in my old eclipse spyder over 10 years ago that the stock blow off valve would not hold much boost and that anything over a certain amount would just be leaked out, so once u change the blow off valve u are able to get more power right there because u can hold and use all the boost that the car was making. maybe its a similar situation to that.

once again im just speculating and trying to learn and understand as much as i can so that i can make a proper decision regarding a pulley upgrade. i wouldnt want to replace my kleeman pulley if there isnt much to be gained by doing so.

You’re nothing if not persistent.

Pretty sure he’s referring to the ubiquitous bypass valve.

GL on the GB.

lidas

Also very interested.

No tail, only you don't get it. Pulleys are nothing new to the street scene. They may not teach about them in crop dusting school but that is your issue.

Spite never wins. As always, you attack without thinking things through. Now go ahead and correct me and add all the proper part numbers to prove me wrong and them fade from this thread like you do every other one that you try to attack me on. You think by leaving a thread when you are down makes everyone here forget?

You know, Tail. Some of us actually enjoy your banter because it gives us a good laugh from time to time.

As far as your question, ask Brad. He sure didn't hesitate to slap me with a warning for using coded curses and insults but you seem to have better luck.

LEARN HOW TO DRIVE and don't be such a sore loser.

I did notice some lag when I had the 180mm put in. I can't say for certain though, but the feel of my pants told me that there was some lag.

C32madness

I think lag is the wrong choice of words here. I am sure what you are feeling is the heaviness from having to accelerate the mass of the supercharger faster. If you every converted a car from dual mass to lightweight single mass flywheel you would understand the concept.

Congrats on a strong setup.

I am digging the kleeman headers with stock pulley and tune. Got LET lined up to do the reflash next. Should be stronger with the tune.

Still waiting for someone to part with their 168mm pulley.

TexasSteele

Would've been AWESOME 48 hours ago...lol

Just placed an order

squidj

So what's the price gonna be and how will the 172mm perform with the regular cooling system?

III II I I AMG

i am rlly confused... what i was taught as i was growing up is that smaller pulleys spins faster than bigger ones therefore it makes more power.... that's not how it works with these cars or was i mislead

Timeless

That would be true if this were the supercharger pulley...but this is the crank pulley.

InTheBenz0

Can someone from LET come in here and tell us the break down and the difference between a 172, 175, and 180 respective pulleys..

E55Pilot

BWAHAAHAHAHAHAAHHH Still think you know who I am and what I drive. Jangy you are delusional. if you're such the driver why don't I ever see you at the track? I know how to drive and drive very well. I make a great side income private coaching drivers. what have you ever done?
