Yes, sure it is.
I know the Cerini brothers very well and could help, if needed,
to get everything organized.

Just, have a bash - what's the worst that can hapen? :lol:

I had some vernier pulleys fitted and timed at Craig Moncrieff thsi year, when the water pump and timing belt were being changed. Not a massive difference to be honest, but then still running the stock 190 ECU.
So did you get details on before and after measurements?

If I remember well, a friend of mine bought an almost new 340R with a lousy power output,
but with high fuel consumption (sounds familiar to me, lol).

They bench tested the car in this conditions: 140 HP

Hope this will help

No dyno runs before or after, I just took the opportunity to have them adjusted to factory settings whilst the belt was off; I’ve read that the can sometimes be out from what they should be.

It also spreads the cost a little, should I decided to get an Emerald in the future….still thinking about this one!

I understand what you mean. I was curious if you got any info on what the measurements were before adjustment of the inlet and exhaust. Good to know it's been done tho. Was it an engine in-situ job?

Yeah unfortunately I wasn't able to get 'before' readings Rich. It was done in-situ, so I imagine through the wheel arch when the tensioner/belt/pump was being changed too.
