These 3 items are required on the new build I will explain why. Ive purchased the Pump but am awaiting Mark to agree the other parts are OK.
Here are the Calcs to show why a Protec p1 is required & my Automotive Eliminator cant cope at my Spec. The aim was to find a single pump to cope.
The criteria is 1000bhp on Methanol @ 4bar of boost we may not push things that far but we wanted a single pump to cope with that.
Here are the cals for Methanol .First you require the Brake specific fuel consumption of the fuel quoted by the manufacturer. Methanol = 1.2 for a comparison pump fuel is .6. This means you will require twice as much Methanol as pump fuel.
To calculate the Flow required in Lb/hr = Bhp x bsfc or 1000 x 1.2 = 1200Lb/hr. Divide by the weight of a gallon of fuel = 1000/7.29 = 165 gall/hr
So we need apump to flow 165 gall/hr @ 3.5bar ( fuel pressure) + 4 bar ( Boost) =109psi.
I found only 2 non mechanical pumps that were still on the flow chart at 109psi. My own Automotive pump rated at a 1000bhp is off the graph at 90psi so useless at these boost levels.
The Protec Veyron P1 is quoted at 119gall/hr @ 110psi at a Voltage of 13.5V.
If you increase Input Voltage the Pump will flow more & we already use a 16v Accuvolt system in the car. At 16v the P1 will pump 149 gall/hr so we are on the right track.
Using a FMS Powermax will increase Volts to 18v & is controlled by the ECU so only adds voltage when required so the pump does not get hot. At this Voltage the P1 cranks out 173galls/hr. The P1 is rated to take 19v input so that’s safe & is the solution.
We also need to monitor EGT at each exhaust port so the EGT module will send the info from 4 'Stinger' probes to the can bus of the ECU.
Im also sending my cam cover to be machined today to accept the cam sensor we are doing this to open up the area for my dry sump .
To the sad trolls that follow my threads like a One Direction groupie you are permitted to use your 'Rod is boring' tags to excess on this thread because to Fuckwits knowledge is boring 
.
look rod, all that science and numbers and the like is fine on your rebuilding your car thread, this thread is a get well soon thread and we dont need to learn about cars here
and ive added some tags as you requested
ps, is that fuelling for a built in safety margin or to provide the power needed?
