The new turbo is a Efr off the indycar platform. It has a stainless turbine not a cast iron one and it also runs any alloy watercooled centre

Sorting a few issues with the new indycar turbo setup. The old 38mm wastegate cant cope so was seeing boost creep. Pulled the pin at 6.8k rpm when we were seeing 12psi of boost. (meant to be 7).
Rev limit is 10.5k RPM so new setup looking promising once we on top of the boost issue

Thanks.... Not sure the driver would know what to do with the power. It was making 50% more torque when we pulled the pin.

But no punching senior team members over dinner.

I'll need bigger balls and I'll need to sort the traction control
