Quick update of Turboed Locost:
Last 3 race weekends the Tullos EBC didn't control the boost at all. I was running with 7 psi spring on a wastegate and with 170 hp on the wheels instead of 208.
While troubleshooting Tullos EBC, I left out the wire to Solenoid completely and WG had same pressure on top and bottom of the diaphram.
It was very noticeable first time accelerating out, and Tullos showed 17 psi peaks. I thought 115000 miles was enough for the motor and used gas pedal as boostcontroller and had pretty fun time for a while.
Result was melted pistons on 2,3 and 4, 4 was worst.
In addition to this now broken engine, I have 99 motor which has spun bearing, so the crankshaft needs machining and one of the connecting rods needs to be replaced.
And the questions:
I have 99 block, can I use 96 crankshaft and rods on it with 99 pistons?
I could use 99 head (needs some attention) or 96 head which seems to be fine.
And for the better engine:
Is anybody running with Belfast setup yet?
What is the actual delivery time for is rods and pistons?
Is the normal failure mode of Electronic boost controller such that WG remains closed?
Thank you for your time
