Rcc stage 1 turbo kit reliabilty

[AsleepAtTheTree]

Title says it all...

My biggest concern i would think is the fmu

Arent those things known for failure??? $4500 kit and $3500 bike gone to waste

Wouldnt secondary injectors be a better option???

Is there a known stage 1 kit with secondaries???

Thank you

[AsleepAtTheTree]

Think i kinda answered one of my own questions tho???

Which is a secondary injector system would be overboard for a stage 1 bc of the needed cpu to control them???

What year Busa? FWIW I rode my gen 1 for 3 years with a FMU no issues
usually issues come up when you BOOST UP
metal shim on the diaphragm distorts
bigger injectors and PCV-TPI is the easiest and most reliable way on a Gen 1

Year 2002
Three years is awesome!!!

So use rcc stage 1, discard fmu, replace with s2000 injectors and use PCV-TPI instead???

Do you know anyone that has done what you suggested???

Prolly bigger then S2000's ,lots of info on injector sizing out there
I am running PCV-TPI and ID1000's right now
Swap back and forth between that and my megasquirt standalone in like 4 minutes

Zeitronix Data logger to tune it myself and she purr's like a kitten

FWIW
I have used
the FMU
Port Fueler secondaries and controller
Port Fueler with megasquirt
Megasquirt with ID1000's
PCV-TPI with ID1000's in that order was my progression remember I have been turbo a long time, a lot of options did not exsist for me in 2008 of whenever

The FMUs that rcc makes are shimless and are extremely reliable. But with any fmu you’re limited to how much boost you can run safely.

The next best option like said before is big injectors and a PC5-PTI. This the set up I went with on this guys bike. However drivability is in direct correlation with the type of injectors you buy. Cry once and buy some ID1000’s.

Thanks again man!!!

How much do you charge to tune a rcc stage 1 gen1 kit with fmu???

Or is that something u dont discuss on the forum???

Do you stay pretty busy??? Im located in alabama, would have to trailer to you??? Whats possible turnaround???

[Boosted Cycle Perf]

It’s $600 for a tune. I’m always slammed, but if planned ahead of time I can squeeze you get you turned around in a day.

as stated the rcc fmu is a shimless design, and we havent had a failure to date (been making them since 2014 or 15). unlike a bunch of the other brands out there. its also e85 compatible. 10-12 psi boost is about the limits of what you can do with them and have a happy fuel pump. the fmu would operate at much higher pressures, its just that the bulk of all electric fuel pumps dont flow worth a damn at those elevated pressures (over 100 psi fuel pressure)

HI. Have you seen the DME mechanical pumps? How do you think you FMU would work with one?

FMU are for electric fuel pumps. They increase fuel pressure as boost increases. Mechanical pumps are engine driven. The faster the motor spins, the more fuel flow and pressure.

Why yes I have...
