tuning a 911 with PMO Carbs
As per title
I have a 911 fitted with a 2.7 on PMO carbs and ssi’s in the shop that needs a tune and final set up.
Car goes well
Everything’s new, rebuilt or refurbished
Cars done the running in miles and It needs that last bit of work to make it spot on.
I was thinking people with rolling road accessible to them would be ideal but experience will trump a RR
But I can’t think of any companies that do Carbs & Classics with rolling roads near me!
I have an idea I’ll end up in Aylesbury at Neil Bainbridges shop. I have a lot of respect for his skill set.
Any recommendations for rolling road or alternatives are welcomed
We are based London UK

Re: tuning a 911 with PMO Carbs
I have a hot 3.2 on big PMO 50mm carbs, twin plug etc.
For the final tune I used a very local RR who deal with about everything 4 wheeled, modern to classics. They are in Dudley West Midlands, so no good for you.
Bainbridge would be a great choice i think.
Many are put off by PMO carbs, but one they know DCOE jets etc can be used, it falls into place.
Tricky bit is getting the RR operator to tune them for drivability (road) engine rather than max WOT bhp.

Yes Neil, that’s him.
All cool calm and collected approach.
Not a new kid on the block.

Mr Hillcllimber
Your car with PMOs
I’ve seen it’s a Lola special so this might not be as applicable but…
What’s it like cold start and hot start?
& Thanks for the pointer
(Webber DCOE jets Good to know)
Neil
Northampton Motorsport also looks like a good shout
Dudley is a bit of a journey though
I’m willing to travel for the right people.
Thx

Re: tuning a 911 with PMO Carbs
Cold start is a bit of a churning slog.
By this I mean pump the throttle hard a few times and turn it over and keep tying for about 10 secs. It will catch but is hard to keep it running, but soon it will be consistent inside of a minute.
When fully warm it is very drivable.
It also hot starts throttle free almost instantly every time.
My old 2.2T engine was the same!

Re: tuning a 911 with PMO Carbs
Possibly of interest, but this is my 3.2 on the last rolling road run when it was about 10 miles old, absolutely fresh engine, so we were careful.
Please turn the sound up when watching, but the car drives like the engine sounds.

I use a guy in north Essex, old school rolling road, no computers involved, no power runs. He is a carb whisperer!
