Comparison of the 2014 SVHO injectors and Supercharger
I pulled an injector out of the new 2014 FZR to have a good look at it and share some info with you guys.
As you can see from the images. The new injector is shorter than the previous models by a total of roughly 7.70 mm.
Connectors are identical.
Information I received from Yamaha is these new injectors flow 29% more than the previous FZR injectors which puts them at around 60 lb hr flow rate.
I know a lot of you will ask.... will these SVHO injectors fit in my older FZR?
The answer is Yes, but with modification. They will fit the fuel rail, fit the connector, fit into the intake manifold, but you will have to mill 7.70 mm off of the three fuel rail mounting bosses on the intake manifold for proper fitment.
I suspect a lot of these 60 lb injectors will be for sale in the classifieds as the guys upgrading to the 1000cc injectors will be selling off their stock ones

We also removed the supercharger from our 2014 SVHO to have a good look at the supercharger impeller. The new 2014 SVHO makes a whopping 60% more boost than the previous supercharger.
Here's some comparison pictures for you guys.

It will be fun to see the data of how Yamaha deals with the 67 MPH thing with all this apparent new power. Someone needs to install a CMD on one of these and see what is happening.
60% more is a bunch.

The speed limiter is timer based. The ECU will allow full throttle for X amount of time allowing full 7800 RPM for the hole shot and midrange. After X amount of time the ECU closes off the throttle body to limit RPM to 7300. The reason I say "X" amount of time is because that amount of time can vary based on inputs from the speedo paddle wheel.
It's very noticeable when this limiter kicks in. You feel the ski back off in a big way. This limiter will be easily circumvented with a Riva SCOM, or better yet, a V-Tech or R&D reflash.

Regarding the ECU, Outside appearance and connectors are the same, however internal circuitry are different. This ECU currently cannot be read or written to, but will be reverse engineered soon enough

Jerry, If I read this correctly the connecters to the ecu are the same, so can we just install a older R&D reflash and go. I mean a bunch of us use the reflash with bigger injecters already anyway with no issue's. I mean install and go and ofcoarse moniter AFR.
I am sure many want to know.
I personally would just buy Suburu inj. then have to mess with milling my older intake to fit.
Thank you for all your insight.
