The new engine will go into the car after Xmas as we are only just now about to start the OEM engine with a Motec M150 tomorrow (7 Dec).

When we have the M150 running the EM engine, we'll install the new beastie and see where we get to.

The heads have sufficient flow to make just over 500 at the crank but it remains to be seen whether we can actually get that

Investment to date is 5 figures starting with a 2 ........ it is NOT cheap.

Be very careful what you wish for.

Best you speak with Clark Steppler or Ben Pila at JWT
