maybe a bad choice of words, but you're right, he's getting less slow day by day. I meant as opposed to going to Kleemann like Dragon did and just getting the whole shot done in one trip.
Just Ordered AMS Pulley from LET.

Make no mistake, I'm very miss-informed. However i will have a review with dyno gains from the the AMS pulley

Kleemann: Autorotor "same as Kenne Bell"- 2.4 litre, 4 male, 6 female lobes. larger bearings. High Boost
Renntech: Lysholm "same as Whipple" - 2.0 litre, 3 male, 5 femial lobes, smaller bearings. Mid Boost
AMG: IHI "Japanese clone of Lysholm",
OEM-4 Cylinders: Eaton "Roots Style" least efficient.
That was why I decided to go with a used Kleemann ($7-7.5K) instead of a new Renntech ($15K).

It is "whp" but likely not "bhp" because it IS an efficiency-type mod. I.e. you should be lowering your percentage of driveline loss, due to less parasitic drag off of your pullies (because you'd now have pullies with less mass). So, you should pick up a few whp with this... but I don't think it's a lot.
hooleyboy, you might want to consider udp's at the same time - combined with the AMS pulley, you should notice an even better bump in rwhp and rwtq.
I think LET makes underdrive pullies for N/A cars - you should check with Erick, if interested. If they don't, I'm pretty sure evosport makes them for your car - so that would be an option.
Thanks for sharing all of your mod info so far - sounds like it's turning into quite a beast

I have two questions if somoene is kind enough to answer.
Why did you order an AMS PULLEY FROM LET, instead of just getting it straight form AMS. Btw, AMS isnt very legit, their rep is really low, they copy products from other manufacturers.
Second question. Why mod an NA? Its so expensive and the gains are so small.

With the ams pulley the rwhp won't be seen as much as to how the car changes in the street. It will pull a lot better in low end, the torque is really what i saw mostly in the dyno with this mod. Hooleyboy don't be mis-informed just ask that way you don't make any mistakes.

Here we go again... Bogus AMS claims
As most reasonable people know - it's the torque in combination with vehicle weight which sets the acceleration rate and HP in combination with drag that sets terminal velocity.
So yes in an extreme case removing rotating mass will enable more torque for acceleration, hence why light weight flywheels are popular. This effect is most noticeable in light weight cars with hi revving engines and little torque to start with - ie race cars and the like. On 3000lb + road cars the effect is minimal, especially when you have a V6 or V8 with gobs of torque to start with.
But my beef is with the bogus 10HP increase and improved mpg - a light weight pulley does not help, nor does a light weight flywheel.
In fact I've never seen anyone claim hp or mpg improvements by using a light weight flywheel, much less a light weight pulley.
