ams crank pulley and Evosport Underdrive pulley kit

Bought both ... I"ll have them installed in a couple weeks and give some feedback.

I'll do another pre/post dyno so its around the same time of the year.

Props to Let ... Erick responded freakishly quick.

Congratulations on the new upgrades, I've heard they add power by decreasing voltage for the cars electronics and a/c.

I'm not too worried ... I dont run a super audio system of anything in this car. So there really isn't anything additional that is draining the electricity.

I only have a V1 and a datalogger.

The two together are a fantastic combo, They take care of both the low end, midrage, and top end. Your whole powerband from idle to redline should get a very significant boost, A few of the C55 guys have done th combo togethrer nad seen great results. I'm interested to see the results on your SLK.

What does the Evosport pulley underdrive? Just the alt?

You can remove the ecu and hand it in by yourself why take the car there.

I have those on my SLK55. Honestly, I don't think they add too much power, maybe 5-10whp. I had them installed along with a new ecu tune and new airfilters, it was about a 25whp change total from these changes together (ecu tune and filters probably accounted for at least 15-20whp of that)

Why would you install them on your car when it says, "not for kompressor cars"? The one looks like a water pump pulley, which if it's a underdrive pulley will slow down the water pump some and with a kompressor might cause cooling issues. Take it other two are smaller one alt. and larger one power steering pulley. I would think you'd pick up about 10-15hp with these on a n/a car.

Send it to me and I'll let you know ... JK did you try contacting the company? Does your car have a S/C or is it stock? If it's stock let me know how everything works out I too am thinking about getting pullies!

update

received the LET(AMS crank pulley) still waiting on the Evosport underdrive pulleys to arrive.

The AMS crank pulley definitely looks like a quality piece. I"ll have them installed after I get back from vacation.

update

just a quick update ... I asked Evosport to delay my shipping since I won't be back until next week. But the Evosport UD pulleys were ready for shipment last week.

Props to Evosport for being on top of the board!

its installed

but no real update ... the belt is a bit tight so I'm going to replace it with one a bit longer.

Also need the ecu to adapt to the pulleys. After I change the belt and let the car adapt a bit I'll take it to a dyno and give feedback.

pedal ECU reset usually speeds up the adaption process.

pedal ecu reset?

what are you referring to?

Sneaky reset doesn't work on the 7 speeds. I think the only way to reset is to unplug the battery for a period of time.
