Why Did My Engine Blow? - Engine & Ancillaries/Gearbox - The Lotus Forums #ForTheOwners Jump to content

Hi Guys;

The engine on my Exige blew a couple of weeks ago, I'v just gotten the attached photos from the garage, and it seems like some serious detonation was going on. The car was running 98 Petrol and the tank was brimmed (so I doubt it was fuel starvation). Pistons 2 and 4 melted, valves bent, bores are scoured, head pitted, a real mess.

The Engine has standard internals with the full BOE TVS300 kit, 2Tubular exhaust, ITG intake, Moroso sump, and BOE map. It was running very rich, however I was informed that this was to keep temps down..

Does anyone have any idea what could have caused this? The BOE kit is supposed to be the safest one out there, so I'm trying to figure out how I can prevent this from ever happening again when I rebuild it.

I've obviously contacted BOE, however third party input is more than welcome.
