Dellorto Update Kit experience
Bizarre - September 21st, 2013 at 01:18 PM

Does anyone run the Dellorto Update Kit ?

I have Dellorto 40's and use to run 34 vents and 140 or 145 mains

I put the spray bar update kit in a while ago and you up the mains to 150's

It ran/runs fine.
No massive power increase.
On decelleration there is a bit of a burble.

Anyway - today I put the 140's back in because........... well I had nothing to do and the car was running fine, so I thought I would just put them in.

Anyway - the car seems to run better. Crisper. The deacceleration burble seems to have gone.

I am not appearing to get hot - just running one of the dip stick sensor things and feel

I am now putting the 145's in - bit of safety.
Just nervous changing from what CB recommend.

Just interested if anyone else is running and changed from CB's recommendation

Not sure about recommendations, however I'd always trust a wideband as every motor is different.
Do you have access to a wideband to check it?

I did have it dynoed about 2yrs ago and I think it was slightly rich

Just cant remember how much

There is carb Services round the corner
Might take it to them and do some tests

Pop over one weekend Baz and we can hook up my wideband and check it :tu:
