(SORRY IF YOU'VE READ THIS IN CHIT-CHAT ALREADY, I JUST REALISED THAT THIS IS WHERE THE BOFFINS PROBABLY HANG-OUT!)
I’ve read on Blat Chat in the past about how people would like to fit Ducati V twins* into their Seven to get the character of a bike engine with a V twin exhaust note.
There are probably a few reasons why (to my knowledge) it hasn’t been done to a Caterham.
I presume things like packaging, complex exhaust routing, idiosyncratic build quality (?), etc…
Watching the British Super Bikes from Cadwell the other weekend I saw a Yamaha R1 running close to the front but using a technique call “Big-Bang”.
Low-and-behold a Japanese inline 4 that sounds like a Ducati.
The bikes got into using “big bang” a long time ago for racing.
I think basically they fit a new crank (and cams?) which allow the firing order to be changed to the pistons firing in pairs. This is meant to slow the frequency of pulses to the rear wheel aiding traction.
I don’t think that traction is such an issue in bike engined Caterhams (Que. lots of quoted replies disproving me!)
What about a “big bang” bike engined Caterham?
Would it eat crank bearings?
Would poor balancing leading to lower rev limit?
Would you ultimately loose power due to reduced running speeds?
Anyone fancy putting their money where my mouth is? (and don’t say up my 🙆🏻)

*Other V twins are available.
