You will be down about 1 -1.5lbs. This is why I am making 190 mm. I will have data shortly.

more detail? since the sc is belt driven so shouldn't it produce same boost at the same rpm regardless of gear.

Boost is relative to load not RPM.

Correct.

Lower gears have lower load.

When can we expect the 190mm pulley and software to be available.

175 and 190 share the same damper. The outer ring is what gets changed out.

So if your order 175 mm damper, you can always update it to 190 mm.

I will have more data on 190 mm later next week.

Vadim is your CLS55 mid pipe something that you keep in stock or will it need to be fabricated?

The client with 190 is on vacation and will be back later next week. As soon as he is back - he goes on the dyno.

By chance did you get dyno numbers and data log boost pre 190 pulley? Is the 190 pulley the only mod he's adding? If you did could you please post the numbers? I'm really curious what kind of boost gains you'll see. Could you also please post up his mod list.

Thank Vadim!

The best part of new pulley design is that client can go from 175 to 190 in under 30 minutes.

I will have data shortly. Thank you for waiting.

Is it necessary to tune on a dyno or can you go out to the track and log info and tune while on the track?
