After a week in the mail, new jets arrived on Monday and main jets are now down from 140 to 130. Emulsion tube still F9. Air jet reduced to 190 to be on the safe side.
Difference in performance is obvious: Where it used to drop off over 5000 rpm, it now produces full torque all the way to 6000 and above! This is how the Holbay cam should perform.
I did a quick run down my local motor way yesterday, and I dare say the performance is absolutely satisfactory. With the engine still "taking off" at 3000+ rpm, but rev'ing freely up 3000 more, the car can really do some serious "pulling". Still accelerating hard 150 km/h in fourth, I don't dare guessing on the top speed!
No work is done until the paperwork is done, as they say. And that applies here too: I have to go back to the rollers now and finish the tuning. I've got a few more air jets to play with to get the very top end absolutely right, but so far my car has never felt better than this!
I've got no photos this time, so you'll have to do with your imagination
However, here's a link to my jetting chart with the entire jetting history. I may write some notes about it at some point as my comments probably need some explanation. After all, the chart also reflects the "learning process" I have been going through (not to mention the problems I have had):
