Bosch 30% Injectors

[plastick]

Just installed these last week and we’re already done with tuning after 4 revisions. Car pulls like a freight train on an S280, god damn. Just wanted to share lol. Also my injectors were dirty AF. I need a walnut blast!

Logs look great and there’s minimal fuel rail pressure drop so my stock HPFP is handling things just fine on 93. I imagine ethanol will change that, but the motor is getting sleeved and built this summer first, then HPFP and -all the boost-

car made 276whp/314wtq on stock fuel and now I have no idea what it’s making with the injectors but it feels REALLY good

The injectors Don't live in a very clean and friendly environment. So it's pretty typical of them to be dirty. I'm starting to wonder how nice looking mine are. Maybe I'll join the 30% injector band wagon soon enough....most likely when my DHM setup goes in so I don't have to pay another $250 to make a major change to my tune.

That's great news! Congrats! Now if the Jag injectors wind up working, we'll have an injector solution that doesn't kill the bank. Glad i've been too broke to buy the s280. Things just seem to be getting better and better for this platform as time goes on.

I also installed the Jag 30% injectors. I went one up and installed the Jag HPFP part number 66807. It's a blind test and it seems to be running good so far. I waiting to see what my tuner says.

Are injectors a pretty easy driveway installation?

Would love to see a dyno of stock vs bosch vs jag!

Watching this as I'm maxed out on the 2860

There are just 2 injectors - the OE and the Jag OE which we're also calling the Bosch +30%. We know this thanks to @Old Mike Emerson 's patience and stubbornness. RIP, Mike.

They're actually really easy to pull out by hand, just a wee bit of wiggling. Installing them is a bit more difficult. Go by feel, and make sure all 4 injectors are at a very similar height. You may have to wiggle the injectors down into their orifice. It's a tapered seat, so it will feel very tight with the injector seals installed properly.

You need to make sure you have the resizing tool for the seals, otherwise it won't work

That's the master kit. There's this: https://www.amazon.com/CTA-Tools-38...1e-8413-f658b75daf26&pd_rd_i=B08SJFZXLY&psc=1 (man, that's a long link...)

... and I think that you can buy the resizer by itself, which is what you really need.

That's not too bad....But why would you need to change out the seals? I get the double seal by Pumaspeed. Are the white a better temp rating or thickness to seal better than the Blk. One or vice versa?

Someone in another thread says this one works. I have it as well as seals but haven't messed with it yet.

I've heard that the Ford black seals are tougher than the white seals but I'm not sure I'm going to bother to change the seals when I install my injectors even though I have a set of the black ones.

The Pumaspeed injectors have been machined to accept dual seals. I don't know if that's required or just something they did to differentiate and charge a bit more. I haven't heard of any FiSTs leaking at their injector seals.

I just installed the Jag injectors without any of that stuff. I just rented a 5lb slide hammer pulling tool from AutoZone. Mine were pretty stuck. I switched over the metal spacers from the old injectors and popped them in. Did some custom work to install the Jag HPFP. Buttoned up everything and crossed my fingers.

What do you mean exactly by "custom work" for the Jag HPFP? Just in case someone in the future tries it out.

Had to trim the coilpack holder tray to allow it to sit properly.
