July and August 2016 were a bit difficult for us. We went to the Summernationals with the turbo repaired and some new EGT sensors in the hope of gathering some more accurate data but a loud pop on the burnout of the first run again killed the small turbo. The carbon seal hadn’t worked.
With the seal replaced with a stronger version we went to a RWYB at the Japshow but the same thing happened again, only this time on the first run and it blew the inlet manifold apart for good measure. The team decided to bit the bullet and move the throttle body from in between the large and small turbos to after the small turbo. Lots of time and fabrication, but it would mean the turbo wouldn’t need a carbon seal.
Old manifold opened like a tin can:
New manifold with throttle body moved:
