cheers paul
Clarke’s ran 800+ on E85, made around 690 and something on pump fuel.
The E85 allows the engine to run cooler too, so it was loving the near 3bar of boost. Just ran out of fuelling.

in america there has been a few 1000bhp zetec engines but its a case that they get rebuilt after a few races . I know one bloke i spoke to and he filled all the water jackets with concrete and run it on methernol but it only lasted 2 runs and he was running serious bhp . He changed over to the ecotec engine in the end .
I always look forward to hearing about the zetec as it always gets slating compared to the yb but if its a 700bhp and reliable then surely its on par if not better in terms on not paying the over inflated cosworth tax
26k for a cossie engine compared to 10k for a zetec

It doesn’t need much more power lol
But it would make more in the current form with more boost. It’s a drag engine and had been holding together fine so far!
There’s a Zetec used in a drag car in Malta that has a concrete filled block and water cooling in the head only. He is well over 600bhp too.
