modify the cold start sounds like a good idea, maybe josh will chime in with how his acts in colder weather. with daves franken jetta he had advanced the timing to 1.15 or 1.20 or so and alleviated the problem and then dynoed nearly 200whp, but he also had a 9mm pump head so i don't think it is comparable, and i don't think u want to go down to the 9mm head either? but like you say perhaps you will be better off with a heavily ported 1.6 head, maybe taper the edges where the valves are recessed in the head to drop compression slightly and gain flow but that is all
my franken started up stock glow plugs and no block heater at -12F last winter. even made heat too. Smoked until you drove it, then no smoke
i believe josh told me his timing was right around stock spec.. he is WELL UNDER 1mm static timing.. i think hes running like .83, or something like that.. under .9mm tho for sure..
but he also had a 9mm pump head so i don't think it is comparable, and i don't think u want to go down to the 9mm head either?
Quotemy franken started up stock glow plugs and no block heater at -12F last winter. even made heat too. Smoked until you drove it, then no smoke Starting it isn't a problem and it'll clear within a few metres of driving.What I hate is the cloud of white smoke on start up, the ropey idle until it's driven a few hundred metres.I don't think a heater is the solution - that's just papering over the cracks, I did think about modifying the glow relay to run on after the key is turned.Quotei believe josh told me his timing was right around stock spec.. he is WELL UNDER 1mm static timing.. i think hes running like .83, or something like that.. under .9mm tho for sure..I'm just over 0.9, did he suffer smoke.Quotebut he also had a 9mm pump head so i don't think it is comparable, and i don't think u want to go down to the 9mm head either? Already gone back to the 9mm, the 10 was too noisy for no gain, the 9mm can deliver enough fuel at the moment to paint the street black.

it does smoke on first start up but once its driven, not even 100 yrds. its smoke free. True, it'll fart and studder on first start
