Vishnu Fuel Rail & Synchronic FPR
SOLD!!!!!
I have for sale my excellent Vishnu Dual Feed Fuel Rail, with custom aluminum end plates. Also included in this setup is the Synchronic Fuel Pressure Regulator. I placed the product features and details from Synapse own site to better explain the benefits of a piston actuated FPR versus the traditional diaphragm. It is setup as a remote custom billet aluminum mount with built in FPR Gauge that I had attached to the firewall for easy tuning during trips to the dyno. This setup was helping me make 271whp on 550cc injectors.
Recreating such a setup would run you over $500, but I'm selling it for what a new dual feed rail costs in today's market.
Price: $250
Product Features:
• Direct bolt-on to the fuel rail
• Absolutely no additional fuel lines to re-work from stock
• Guaranteed 1:1 off-boost ratio for a proper air/fuel ratio at idle
• Infinitely adjustable from 1:1 to 12:1 boost indexed fuel pressure ratio
• Interchangeable adapters for various applications
• Adjustable static fuel pressure
• Maintenance of fuel rail pressure with engine off for immediate ignition on the next cycle (same as stock)
• Interchangeable bypass orifice diameters to accommodate high flow fuel pumps
• Absolutely no diaphragms to fail, easily rebuildable with new seals
• Tough enough for direct application of Nitrous
• Patent 6,863,260
• The First And Last Fuel Pressure Regulator You Will Ever Buy!
Performance Benefits:
Synapse Synchronic technology has eliminated the diaphragm, by using a piston contacted with an axial contact, engineered, aerospace, elastomeric seal. This seal is designed to withstand 800 psi of burst pressure and resist gasoline and methanol. Because there is not diaphragm, noise in the fuel rail is significantly reduced, allowing the fuel injector to precisely deliver the necessary fuel. A diaphragm has to deflect before actuating the valve that controls the flow of fuel. This results in overshoot and hysteresis from the target fuel pressure. Diaphragms are also mainly flat elastomer sheets with large surface areas. Accordingly, the performance of the diaphragm is significantly impacted by temperature, components of the fuel, durometer of the diaphragm, etc.
We’ve eliminated these problems by linearizing the response of the FPR via friction. Now, when pressure requires the piston to actuate, there is not diaphragm that has to deflect before acting upon it. Think of this like having a baloon between you and an object you are trying to push along the floor. Depending on how much the baloon is inflated, how thick the rubber is and how hot the room is will determine how much of your effort goes towards moving the object, versus simply just crushing the baloon. The effect is, ultimately, how long it takes before the object moves when you push on it through a baloon. That is why we eliminated the use of a diaphragm.
