Eurocharged Performance ML63 and TT lambo
for the lazy..
SC pulley=65.8mm.
Using a Stock Crank Pulley, the S/C pulley would need to be reduced to:
63.6mm to equal the boost of 178mm Crank Pulley running @ 6,200 Engine RPM
62.5mm to equal the boost of 181mm Crank Pulley running @ 6,200 Engine RPM
61.2mm to equal the boost of 185mm Crank Pulley running @ 6,200 Engine RPM

which yields similar performance than say "evosport ODSP" with OUT ECU tuning.
I have been experimenting with my intake in the last few days.
I just removed the intake last night ..and throttle response is back to being a bit slow even with the clutch pulley on. Once the kompressor engages.. the car pulls great.. but not until you hit around 4K is when you get pushed back to your seat.
With the intake filter on.. the punch starts earlier and you don't have jab the pedal as deep to get the car moving.
But as posted earlier.. I covered around 50% of the intake opening with electrical tape to muffle the sound.
I'm going to definately put the intake filter back on.. but going find a better and thicker tape material that will last longer.

its the 1 and 2 punch of the smaller pulley with the extra intake filter...

well, maybe this is because your filters are too dirty, try to clean them or replace them and see how it goes before putting the intake mod back in, I bet the result wouldn't be as dramatic if you had the new filters.

its been really hot around here 90's..
in the evening the cars responds great.. with out the intake mod.
its only during the day when its really hot when performance suffers without the intake.. and even with the intake on, throttle response suffers a bit.

Just a quick update.
Intakes - I apologize for the delay. I was told on Friday I would have these in my hands mid week. The time quote ended up being on the high side, not the low side. We are just waiting for the filters, thats it. Here is a shot of the die cut filter. The piece its sitting in is not part of the intake, it was just made for fitment purposes. The foam will be green. I will send these out upgraded shipping so that hopefully everyone will have them in their hands by the weekend.
Pulleys - Looks like end of next week I will have them back in stock. If you are considering a pulley, don't wait too long. After all of the positive reviews, they are flying off the shelf. They go fast! I actually have an aluminum one I did that I am going to test as well. Its light as a feather
Not sure if I will offer them in Aluminum in the future, but it will be interesting to see the results. Also, I am currently testing a larger middle idler pulley for better tension and more belt wrap I am going to get my car back on the dyno with the new idler and see what she can do. It feels stronger with the new idler, especially down low.
As far as the crank pulley/sc pulley dyno, it got canceled. But, I was assured by the customer that it will happen this week for sure, most likely Wednesday night again.
Also, all good news to report on the belt front. Customers have been calling and letting me know how the car is driving, and how the belt looks. Nothing but rave reviews with no reports of belt wear. In fact, we are going to have 1/4 mile results this evening from the track event that LET had. The car with the SC Pulley had 34 miles worth of 1/4 mile runs today, and said the belt looks perfect. Look for times and videos this evening. It sounded like a fun event. I know there was a head to head run between SRT6s with the 185mm pulley and SC pulley

Well, I really tested out the S/C pulley today at the track rental. With driving around the track and making about 30 runs I put over 30 hard miles on it. No belt problems and my car held its own very well against the other pulleys. I ran Steve Hellums SRT6(renntech pulley & tune) like 10 times and were about even back and forth. His fastest was a 12.51@111 to my 12.62@110.55. Riot (Let pulley, tune & H E) and I only ran once. His 12.6360@109.20 to my 12.6881@110.23(Code 3 pulley & HE and Inmotion tune) If it was not so hot we all would have had some much better times.

I'll sit back and see until the Supercharger pulley gets refined. Upon release a product is never 100%. The tensioner is an excellent idea. Until Code3 has exhausted all of it's R&D ideas I'll be sitting back watching. Definitely eager to purchase it at some point. Who knows someone may in-fact be able to run the 185MM pulley with this product without a single problem who knows?

I just sent you an email in regards to the clutch spinning. Here is the picture from the manual.
Great runs Bikecop! Its nice to get some track numbers for the people that were interested in them. It looks like the SC Pulley held its own today.
