VTT Plug and Play S58 Single HPFP series

Permanently resolve exhaust cam timing shift issues on S58 engines – without cam lockup. Tested to over 1400 hp. Retain the benefits of variable valve timing and enjoy the assurance of peak power.

A known problem with the S58 engine at high rpm is exhaust cam timing offset, which can drop power by as much as 200-250 whp. The cause is the exhaust cam being overloaded as it drives two high-pressure fuel pumps, stronger valve springs, and high boost pressures.

The traditional solution is to lock the cam, but this reduces either peak power or low-end torque and spool. VTT's solution is simple but effective: we remove the front high-pressure pump, which halves the load and keeps the timing accurate throughout the rev range. By fine-tuning the port injection, fuel demand is also met in high-performance devices.

Benefits:
-Completely eliminates the timing shift problem
-Retains the benefits of variable valve timing – no compromise between low-end torque and peak power
-OEM-style stainless steel fuel lines – no braided hoses or extra fittings
-Proven solution for configurations up to 1400+ hp

The package includes:

• CNC machined HPFP blank

• Rear high-pressure pipe with sensor connection

• Front high-pressure pipe

• Plug & play 2-1 HPFP wiring harness

Installation:
Requires professional installation and customized programming (port injection adjustment and, if necessary, oil pressure optimization at high rpm).
