As promised today we got the SuperCoupe powered Merkur XR4Ti on the rollers to dial in the tune on the Haltech Elite 2500 engine management system. Everything went real smooth and we made 100rwhp more than stock at stock boost levels. This Ford V6 is surprisingly efficient and this little car is a rocket!

Progress report on the 5.4……

With a solid bottom end having gone together already, we needed to make sure the rest of the package was worthy and not going to stand in the way of some decent power numbers so we called Comp Cams for a pair of custom cams to go on these Trick Flow 195cc CNC Race Port heads. We went with all the lift (.585”) that P2V clearance would allow (.050” intake, .080” exhaust) and tied it together with some ARP studs. Man that stuff will make your eyes water a bit. Iykyk

With conversions to aftermarket ECU’s becoming more common, the importance of quality custom connectors is becoming more apparent. Nothing worse than chasing intermittent faulty connections. Here we take you step by step through making a good connector in this case for our Haltech smart coils.

As always the right tools for the job can make all the difference. Don’t skimp. Invest in some tools!
