By ACO/ ALMS regulation, this engine is based on a stock block. I didn't see that mention in the IRL announcement for their 2.4L spec.

And it's a twin turbo (the side you can't see is identical to the side view). I don't recall the IRL mentioning the term "twin" in their descripton. If anybody can sort these points out, please do.

So we could see this same engine de-bored and/or de-stroked down to 2.4L, or something completely different. The IRL engine might be a proprietary racing block, and the decision to make it a stressed member has been stressed by Berkman of Honda. That's the "expensive jewel of a racing engine" that Berkman described some months ago.. .

Interesting. There's a rumour that Mercedes might be the major engine supplier to F1. The current spec is 2.4L aspirated.

So do Honda have aspirations to go back to F1 as an engine supplier, without turbos?

Equally could we see a return of Mercedes to IndyCar, with turbos?
