Understanding Racepak flow sensor data

Hello, I'm getting ready to put a racepak on my blown alky SBC and it will have a fuel flow sensor, along with a pressure reading directly on the pump (from the outlet) and a sesor reading on the nozzles.

I understand that the flow sensor basically will tell you how many GMP of fuel your motor has consumed. How will having this data help in tuning?

I'm also guessing that by having pump and nozzle pressure readings it will show me in real time what my pressure is along a run allowing me to use that data to tune my highspeed pressure.

Can anybody who has a similar setup help me in understanding the value and how to use this data to tune more effectively?

I also had the motor Dyno'd this weekend and by seeing numbers on a screen it helped greatly. This thing makes tons of power, and never wanted to stop making HP

 

First let me say I do not run a car, I work on a TF Harley so it is quite diffrent but the recording of data and why it is done is the same.

In our setup the fuel pump pressure is telling us what pressure the pump is making but keep in mind that result of pressure is controlled by whatever method you use to control the return of fuel to the tank. We use a BDK (DJE Valve). So if I set my BDK to 200psi, the pump will make 200 psi of pressure. If you use a jet can setup it doing the same thing monitoring what pressure there poping off and when.

We install our flow meter after the barrel valve before the ditribution block for the nozzles. Both the flow meter and the nozzles only show fuel into the motor on our setups.

For us the info is priceless. If our bike goes fat at the top end. The computer shows us when and why. We can move the leanout timer to get ahead of it and/or drop our pressure andkeep the bike going further down track under power.

The most important thing you can do is keep records of your tuneup settings and the data your race pak gives you once you start using it. But dont go crazy over thinking it. Been there done that. It takes some time to build trust in what it is telling you. Almost right away you will be able to use the information to make better decisions, but the real reward is after a pile of runs you will have a wealth of information you can dig through and see what changes did what for certain situations.
