I was planning installing a lambda sensor in both my R1 and R2, however the regs may not allow this, I am just awaiting confirmation if its allowed or not.
I’f its not allowed I was thinking of just installing it on my R1 pipe.
So that would mean I would have to use my R2 pipe on the R1 if I decided to race it and when testing I would use the R1 pipe on the R2.
Would it change the characterics of the engines much with:
R1 pipe on R2
R2 pipe on R1
Ideally I will have my nt project jetting dialed in to each engine with the lambdas then I won’t need them as much.
Although another issue may arise, would the jetting change much when swapping pipes?
Firstly, why are you wanting to install a lambda sensor in the first place ? I can of course assume it’s for the purpose of extracting carburation data, but i guarantee that EGT and a good knowledge of piston reading will be far more than enough.
Secondly, the cylinders on both engines are designed to work with the pipe that the platform is homologated with. Will an R1 work with an R2 pipe and vice versa? Of course. Will it grenade ? Not at all. Is it in any way optimal in the way the engine was meant to run ? Not really
Thirdly, depending on where you are, a mismmatched pipe and engine lead to DQ from a tech standpoint. The engine is homologated with its pipe (which sports the engine’s homologation number) and having them not match is a breach of (almost all) technical regs.
In essence, focus on having a good running carburation on the rich side for practice, go run laps and have fun
