Thinking of uping my boost on my Kraftwerks kit with stock internals. Just want to see what other people are running at?

I'm running 10lbs. The highest you can go is 11. If you go over that you will over spin the bearings in the rotrex. So, I'd keep it at 10 at the highest.

Thanks for Info. I did not know that.

Ya unfortunately with that kit you are kinda stuck at that boost level and those power levels. Only option I'm aware of is to get a larger blower, but I'm not sure if you can use a larger blower with that kit.

Yea unfortunately the c30-94 doesn't produce much boost. Without an intercooler someone made 18psi but remember more boost isn't everything.

We need to create a 'Kraftwerks Modification' list to see what can be done for this kit.

Where are you located? Could be the air in your area is more dense. I'm curious what's the pressure drop in the Kraftwerks kits fmic.

It's not that the kit is limited to 11lbs. That is the boost reference we saw during the development of the kit with the existing combination of pulleys so keep the boost down to a level where the OE Map Sensor can read.

There are areas of the kit that can be touched up and revised for more power.

We can change the charger pulley around along with the crank pulley to a larger one so we can re-spec the charger pulley for a different area of the power band and potentially more power.

The piping from the charger to the I/C can be increase from 2 to 2.5" to increase more power as well and then of course the utilizing of camshafts and higher than standard octane fuel.

I was under the impression the charger with the 8th gen kit was being spun as fast as it could at 8200 rpm, am I wrong?

Anyone have the pulley sizes for the blower and z3 crank pulley? I can work the math and see what rpm the blower would spin
