...engine is from RAM Performance...it is a 140 hp multiport EFI version of the dual port 115 hp EFI engine based on the Subaru EA81 block. Though the 115 hp engine was manufactured in runs of 50, the multiport versions were (are?) custom made to order.

...not that I am aware of, although I've found many favorable endorsements on the web of Ron's knowledge and work on the web
....since the floods in CO, I've lost touch w/ Glenn Crowder who is flying a Europa w/ a Sube which Ron rebuilt a few years ago.
It's probably fair to say that I have somewhat of an orphan engine..
Back to the issue of the electrical load of the engine...for the purposes of this discussion, I am quite content to use the figures Bill Bradburry has posted, namely:
| Quote: | EC2 and gauges: 0.8 A
2 leading coils: 2.4 A
2 trailing coils: 2.4 A
2 primary injectors 0.7 A
2 secondary injectors: 0.7 A
1 Mazda stock RX7 fuel pump: 3.8 A
Total in normal running config: 10.8 A

Is there any reason to believe that the hopped up
version of the engine needs any greater electrical
energy for operation than the 115 hp version?

Good starting points. I'll be back Saturday.
