At the moment running the stock Marelli S135 (non vacuum advance) distributor body with a pertronix optical trigger kit. Static set at 10 degrees, mechanical advance is about 28 degrees from memory, so total advance will be 38 and as per stock is all in at about 3500rpm or so... that's one of the things we are going to change. There's another model of Marelli S135xx distributor that uses a 22 degree mechanical advance plate, and we will try the timing at around 15 degrees static...as the low revs response could be improved a little.
If you've set static at 10 instead of 5, then I'd expect you've lost advance up top...
Adding 5 degrees to the static timing adds 5 degrees right throughout the rev range.
Rob,
I am not sure how fast the X was going, but it looks like your shirt went plaid.
I think it’s the best engine I’ve ever built.[/QUOTE]
Sure sounds pretty sweeeeet to me, Rob!!

We were in your part of the world recently, such a stunningly beautiful country!
Hey Rob, what parts of NZ did you travel to?
I would like to have caught up with you (and Yep - talked about X's )
cheers, IanL - NZ
The new engine is approaching 9000 miles.
I think it’s the best engine I’ve ever built.
