FRS-BRZ Port Fuel Injector (interesting)

[Fuel Injector Clinic]

Good to hear back from you, and great to hear that Hydra is making good progress with development here.
Will you or Hydra be at PRI at the end of the month? If so please stop by our booth and we can chat and show you some of our injectors on a flow bench and give you some more info them. We'd also love to talk to Hydra about their fueling strategies and discuss working with them on compiling injector data between our injectors and the Hydra software.

The development of the engine management system was a huge challenge to say the least and took a ton of money and time. Because of the uncertainty in completion time we just couldn't commit to SEMA or PRI. Hydras job ended with getting the OEM fuel system to match up perfectly with the Hydra EMS and it's up to me now to pick and make the aftermarket fuel options a reality.

We have 6 new Direct Injection maps on top of what we already have for the port injection and the data entered for those port injectors is really critical for the DI to adjust itself properly so I'll definitely be looking to work with someone to get very accurate injector data.

We'll have to figure out what the most popular injector upgrades will be so I can focus and develop those options as base maps in the Hydra for customers and dealers.

Great, please get in touch with me when you're ready to discuss that by emailing info@fuelinjectorclinic.com or calling at (561) 427-0082.
We know how important having the proper info is and are interested in working with you to develop this info.

What octane race gas are you looking at that you want higher than E85 offers?

For base maps I'm going to be doing pump fuel, Sunoco 100 Race, and E85. For my personal race setup I haven't decided yet but typically I run Sunoco 110 with our Hydramist Water/Meth injection system. That combination tunes like VP C16 which is 116 octane. The octane of E85 really isn't all that high (106 range) but it has other benefits. Combined with the Hydramist I've gotten shockingly good results.

I really like E85 and I'm going to convert my STi race car over to it next season to test. The problem is that I will need to transport about 40 gallons of E85 just to get through a race weekend (one race car, if I only run 3 timed laps a session). The FRS I haven't equipped it with a surge tank yet so I'll need much more E85 to get me through a weekend since the tank needs to be above 1/2.

*nodding head* ah, ah, yup, cool STi race car, *doing mental math* ok... surge tank...? Annnnd, you lost me.

Ha, ha. A surge tank is a small holding tank for fuel which is narrow and tall, that you pump fuel to from your main fuel tank, and then a fuel pump delivers fuel from the surge tank to your engine. Because it's narrow and tall the fuel pickup isn't starved around turns like the oem tank.

I'm getting fuel starvation with the oem fuel tank at certain tracks even with 1/2 tank of gas. So to keep a full tank I'll need lots of e85. My STi race setup can start a session with only 5 gallons in the tank because of the surge tank.

Looking at that chart that arghx7 posted, it seems like the octane rating effectively goes up quite a bit if sprayed with direct injectors rather than port injectors...:O Dunno what that "130" is but the numbers look like RON (the basic fuel is sitting at 98, which is normal "premium fuel"). 130RON sounds pretty good

Direct injection has a massive impact on detonation resistance. Basically on port injection only, when I was testing that, I could only match OEM HP with E85 and on pump gas I believe I was about 20 whp less.

Direct injection is definitely something worth embracing even with it's limitations which is why I'm really happy the FRS/BRZ also has port injection to supplement fuel delivery.

[???]

When you buy a set of injectors for the FRS, is it a set of 8 or just the direct injectors or just the port injectors. if it is just the direct injectors or just the port injectors, should i get 2 sets of the same or are are they different? is it even worth it to upgrade all of them if they come in sets of 4?

[???]

what types of injectors are available? which is best for street applications? which is best for cars that have occasional track days?

[Hawaiian]

Holy Zombie thread.

[Element Tuning]

Unless you are turbocharged or supercharged you really don't need to upgrade the port fuel injectors. If you are boosted then you just replace the 4 port fuel injectors and upgrade the fuel pump etc.

The DI injectors aren't really going to be touched at most power levels.

What size you need depends on many variables such as power and fuel type. For E85 at least in my case anything smaller than 900cc isn't worth bothering with.

What do you mean by that? Also, are the DI injectors the same design as the port injectors? Just wondering. (I don't mean is it worth it to change them.)
