This cool of a build, and he put a JP manifold on it. Facepalm. hahaha.. In all seriousness very cool build. We came very close to pulling the trigger on the Samsonas, VAC offered us a very good price, but in the end, its just not street friendly at all. Race car, sure go for it. Street car, you will regret it. Looking forward to when this thing is done! As for the EGT probes. This is standard for most race cars, you can see exactly what each cylinder is doing, and tailor your fuel to keep them all pretty even. Well assuming your PI controller has individual injector control.
