    Arrow Going from C3-11 to E1 FZR SHO

    I see it produces 16psi @8000. Some say You need FPR to run 16psi and is there enough stock injector for an E1? I am currently running around 83 at 8550 on a C3-11 and R2

    It says it will produce 16 [email protected], but that is not true. Typically the e1 produces 16 psi around 8300, 17 psi around 8700, and 18 psi at 9000. If the weather is cooler you will get these boost numbers at a slightly lower rpm. You will definitely need to run a FPR with this wheel. When I ran this wheel I used stock injectors with Walbro fuel pump. With stock injectors and stock fuel pump you will be on the edge I believe or it just might not be enough. You also need to know that this wheel will have a vibration (surge) around 4500 rpm, so if you feel this, don't worry about anything being damaged, it's normal with this wheel. This wheel does hit very hard when you pull the throttle, you will love it...good luck!

    I ran mine with 62psi fuel pressure with a walbro and a aeromotive reg. It sat in around 12 AFR. I saw 16.5 at 8700 and 84.5mph.

    did you run it on a static or rising rate fuel regulator also what were your afr's at idle?

    I ran it static. But was way rich down low. then I went 54 rising. If I remember correctly. It ran very well, but had a hesitation with Rising rate. That I thought was a lean spot in mid range.

    So is the general consensus that I am definitely going to need a fuel pump and RRFPR?

    You know you need a fpr at a minimum. Pump has to come out when doing it so might as well upgrade the pump while your at it right ? Then you know your covered for now and future

    I run a ET18 on stock pump, its not needed, the injectors usually work to 14psi......FPR would be nice for fine tuning or if extra fuel is needed
