Is this reply towards me? If so I'm well familiar and very happy client of Toms. He goes above and beyond and his knowledge is on a guru level. Traveled from NY to NC and spend a long weekend troubleshooting my car.
I'll likely end up using his help again if I go with induction but so far trying to learn as much as I can by myself.
I'm aware of his head, we had a brief convo about it a bit ago. At the time the cost benefit wasn't there for me but I might revisit it the issue.
My poking around with fuel map late last season appears to have solved a major problem I've been having with the car. Now I can map my fuel table a lot better especially since I discovered that ChatGPT can make a template of a map for me to follow when I wasn't getting an answer from anybody.
With a solid map and misfire sorted out, considering the fact that I seem to only get 200-400 miles a year out of the car, big plans and tear downs dont seem to make sense unless my hand is forced by some mechanical failure. (which is rather common in my world it seems)
The SC setup is the same SC as Duratec uses for 620R. Reason those are all RHD is because of steering. Since Zetec is mirrored, it's an optimal candidate for same Rotrex SC setup on a LHD car. The 3 roots type SC's I have on hand have been unable to clear S3 (non SV) sizing. SV's have had luck in the past with clearance for other peoples builds.
