Thought some of you might like this article I came across regarding the RA168E engine from the Turbo era of F1, this 1.5L Turbo V6 led Senna and Prost to 15 victories out of 16 races, arguably Honda's most famous engine...

I found it interesting. Thanks for posting.

Noticed they ran IHI Ceramic turbos to 4 bar. Stock skyline ceramic turbos cant take more than 1.2bar so thats impressive!!

The fuels they used were crazy. They were making maz power at lambda 1.1, which is about 15:1 on that tuolene rocket fuel.

And the BSFC numbers are below 0.3!! That's crazy for any turbo engine.

I know one of the Brabham mechanics from those days pretty well. He always said that the only problem they had was the engine management was pretty crude. It was really only Honda and Ferrari that had anything decent and even that was flawed.

I've done retro fits on a pair of Ferrari F1's from that era with modern ECU's, etc. Except we ran on C16. They are fascinating engines to work on. Both cars we've done regularly do 3-4 race meetings without a rebuild running 3 odd bar. It's amazing what modern lambda control, knock control and rev limiters do for an engines life!

Amazing experience Im sure is an understatement!! Unreal? Any pics or more details of the events they run?

During assembly

I'll try and find some on track pics.

I find this era (and the decade or so before) very interesting, thanks for sharing. I just wish more people loved cars for the engineering and not the "I'm so cool" crap. Oh well, I'm done crying.
