1994 Turbo RF build

Before I installed my 150psi fuel pressure sensor , I set the base pressure with the liquid filled gauge I had on the fuel rail. This was obviously not accurate.

I'll lower my fuel pressure to 43-45psi.

Got another 1 gal fuel cell , 3 x -10 bungs in the back ( pump #1, pump #2 and a drain). Need to weld the 2 male bung and a divider in-between.

Here's a pic of my MaxxEcu Sport setup. Using spare IAN 8 for wheelie control and Extra Output 8 for pump #2 relay. I have the external water pump fused direct from the battery so I can let it run with the bike off.

Awaiting my second 400lph pump. In the next few weeks, I will redo my harness including the 2 new devices and shield the whole harness. I'm not in a rush.

For reference, an AEM 400lph pump started to run out of the flow around 750hp, on E85 fuel. That was at 4.8 bar /  70 psi total pressure, 3 bar base + boost.

If you run the pump at 90psi it flows around  225L/Hr 

So if you go north of 400hp I can imagine this will become an issue.

Using this logic - if you need 50lbs of boost to go 400+hp, I think you've got more fundamental issues!

This matches what I see on my log.

Just used the numer I saw in his post: 45psi boost. Add 45psi base pressure, you are at 90 psi pump pressure. This results in around 225L/hr, which seems not enough to support the horsepower associated with 45psi boost.

Killing the time, the weather is shit here in Vancouver. Rain, rain,rain.

I rebuilt the 6 pots calipers in front and the rear caliper. Added a spring to prevent brake drag. Also did some detailing..
