[QUOTE=viren.89;5746175]I meant all of those. I also have a S/C pulley - bosch and bigger H/E lol
Shardul didn't needed to mention anything cuz they both different companies, or maybe he didn't know how EC would work on pricing.
I agree but its my opinion Shardull is a good vendor.
Anyhow, I do understand that how it must suck for you though, not being able to go WOT cuz it ain't tuned yet lol
[QUOTE]It does suck right now but the sound of the S/C sounds so good i just cruise
This however will be a great first mod based on it's value.
I agree 100%
Do you not think that it takes away the luxury feel from the car by making it "throttle ready" all the time? For example in comfort mode
It does! the car is way more agreesive on tap of gas(Beast)
but at idle or traffic light you dont feel anything The car is so smooth it seems like the car is off.
the car used to need more throttle to make a jump and then clutch engages and then the car would go and now it just jumps right
yes it did but the clutch less pulley you dont feel a jerk but instead you feel the car push you back in your seat quickly.
away ? Base question is how do you feel driving the car ? You think the car should've already came like this or do you miss the
On the Highway the car is smooth as silk with a wistling sound from the S/C
in the city it is smooth but be gentle on the gas peddle when the light turns green. because it a beast ready to be unleashed. Im not kidding
clutch engagement ? lol sounds cheesy but these are the things that affect daily drivability.
100% you have to want it..

The 77mm tune is currently being worked on, I would reserve judgement until after its done and tested.
When/if the tune is dialed in, I believe a lot of you are gonna like this mod. The fixed pulley has made the car's acceleration much more predictable and controllable. It does generate higher IAT's than the clutched one at idle and part throttle, but I personally think its a fair trade off.
I'll update once I get some time to drive with the refined tune.

One things a definite with this fixed pulley, I would get a gauge installed that monitors your IAT's, boost/vacuum, and Air/Fuel.
Without the clutch as a fail safe, you NEED to know if your pump decides to take a dump on you.
I have the Aeroforce gauges on my pillar pod and my IAT's are staring me in the face.

Ran into a couple of issues with this new 77mm pulley and tune. It surges on partial throttle and has a very long lag between shifts as if the power cuts off and then returns.
I was asked to reset adaptations in hopes it would alleviate the problem, but now a new problem has emerge: It wont let me go past 15% throttle without going super lean and stall. Resetting the adaptations corrects the problem, but once it re-learns it comes back in the following day or two.
I've decided to take my pulley off until the tune is tried, tested and confirmed. Not sure if others have encountered these issues or if its just me, but hope they chime in if they have.

as of right now my problem is the fuel pump isnt able to keep up. when i was running around 6-7psi it was good. now with the 80mm pulley when i hit 10-11 psi fuel pressure drops big time. after the pump is replace im hoping everything will b good. ill keep u all up dated

Are you running you SLK55 with M113k with the maf unplugged? From what I have seen you had a smaller clutch version SC pulley on your car with a 12v power supply to engage the clutch all the time. What was are AFR on this setup?
You put a bigger pump but are still running stock injectors?

I'm using the stock set up that comes on the e55 engine. With a 255 fuel pump. Mass air meter unplug I unplug the wire for the clutch super charger the injectors are the one that comes with the e55 engine. When I was running around 6psi it was good. With the new pulley I would hit 12psi after 10 psi my Afr is super lean over 14:1

why were you only producing 6psi on a stock SC pulley it should be at least 9 to 10 psi.
If you MAF is unplugged how is the engine seeing the air flow????

the reason it was only producing 6psi at the time is because i had a leak and a restricted line. i since then fixed those problems. after fixing those issues didnt have a chance to test the pulley again but instead went straight to the clutchless 80mm pulley. once everything correct that car will be a monster. with the clutchless pulley it has boost right away. even at 1970 rpm i data log 10psi right off the back.

if your MAF is unplugged how is the ECU selecting fuel and timing values?
80mm pulley to work? I think it is working you are making the boost. I think your issues are coming from unplugging the MAF
