Tony, you are a good resource to have around!

I ordered a bunch of the Bosch 1000cc, hopefully I can find a use for them

I see these injectors in 750cc and 1000cc sizes. I've only got a vf34 at the moment, possibly looking into E85 in the future, provided VA ever gets with the program. Anyway, the price difference between the two injector sizes is not a whole lot. Any downsides to going with the higher flow? Or should I just grab the 750's? Thanks.

From my experience always look way into the future as I didn't... These injectors idle 100x better then my modded stockers did with almost no maf scaling or idle timing - basically just dropped em in put in the numbers and they idle like a champ... They are very consistent on fuel trims - long and short term...

The modded stockers had some pretty serious swings rich and lean...

Going to big on injectors is a thing of the past to be honest... Back in the day anything over 750cc's could not be made to idle good (Honda world) today things have improved a whole bunch..

Do you think these would be better than a set of FIC 1250cc injectors? I was thinking I have fpr already and if im running a bosch 044 intank and these bosch 1000cc, if I boosted the fuel pressure up 21.5 psi think these would Idle and well all out perform better? This is fueling an E85 gt3076 .82 2.5l....

I guarantee you a night and day difference between these and 1250's. Money back guarantee at that.

Tony - I've had a couple of questions about if the 1k's are to big...

For clarification to anyone reading this thread can you lay out info for the 750's???

Will the 750's run similar Fuel pressures as the 1000's. At some random static fuel pressures what do the 750's flow? Do the 750's idle even better then the 1000's?

There have been a couple of people interested but do not need 1k's for pump gas - but have possible future plans of running E85 and would need more fuel than the 750's at 3bar of fuel pressure would be capable of. If the 750's follow the 1000's as far as raising the fuel pressure goes there would probably be alot of interest.

Do you have any suggestions on what FPR to safely run with E85, I've read the Aero unit has had some problems while running E85 - but maybe you confirm or correct that?

Again Tony - thanks for your time I for one really appreciate it!

-Jerod

And just for future reference to the interested looking. Once I got my fuel dialed in - for lower load/idle - my long term fuel trims have not changed - my short trim fuel trims are more consistent and much less scattered.

From pull to pull -day to day- things seem to be very consistent on the fueling side of things...

No more Misfires on #1 either!!!

They are actually labeled as 725's.. but yes they have the same high pressure capabilities of the 1k's and more. Tony's site show they are good up to 120psi and will flow ~1200cc's at that base pressure. They are definitely capable of growing with the car...

Jerod, I asked Tony this question a while ago. The answer is that you can treat 750 as the same as the 1000s, just with a lower flow rate. All other aspects are virtually the same (pressure, pattern, size, etc.).

Tony also has 550 versions of this injector as well. They will flow more than 550 if you up the rail pressure beyond the rated 43.5 psi.

Ok guys I have a question.

Before finding out about these injectors, I ordered a set of 1000cc from fiveomotorsport.com. as it turned out they didn't fit. at first I was happy because I was hoping for a refund so I could get these. But he said that I could have the proper ones sent free of charge. No refund. So I asked him to get me the bosch 1000cc high empedance saturated ones. he said ok but I'll pay the diff. But he sounded clueless. today he emailed me and said he had the bosch 1000cc high resistance injectors in and I would have to send him 80 bucks more.

are all new bosch's 1000cc's like this or only the ones from injector dynamics?

If these arent the ones I'll have to sell them cut my losses and get the saturated ones.

where did you get the numbers? This chart or did yours come with a test sheet specifically for the matched set?

They come with a chart... Flow rates per FPR and Latency's (dead times) per FPR....

Injector Dynamics IS THE ONLY place that sells Bosch 550-725-1000's... Tony is the ONLY distributor for these injectors... He does have a couple of places he wholesales to but I know there is a place that was selling these claiming they were 1000's to the Honda guys and they WERE not... You might give Tony a call asap and get it straightened out because if they are not a dealer for T1 or ID your getting junk..

Just read the T1 "Faq".

As these are 1000cc when tested with gasoline, does that mean that in reality they are equivalent (in flow) to 880cc injectors from other manufacturers?

My de-capped injectors have gone out to just over 900cc. Will these injectors actually flow less than my de-caps?

Call tony he will explain it...

Other manufacturers test their injectors are tested with fluids other than gasoline - which hinders their flow rating....

The biggest factor with these injectors - they are capable of running extremely high fuel pressures without any issues - self upgradable with an fpr (all injectors are - but most have a way lower limit then the bosch's)

Without testing your injectors now, I can't say how these would compare in flow, but probably very similar.

The deal is, 100cc/min isn't going to make or break your goals. If you're that far on the edge of your fuel system, then you need more fuel.

You can get more fuel by a bigger injector or more fuel pressure. We all know of all the negative qualities you gain by going up in injector size to 1600's and the reality is that the little that's available between the 1000's and 1600's aren't any better.

These injectors have the capability to safely go up to 100psi base fuel pressure, at which they flow 1525cc/min. For the most part, the guys looking for more than 1000cc/cylinder are running E85. We've made over 600whp on 1 set of these ID1000's running only a walbro in tank pump and a Bosch 044 inline pump, with 100psi fuel pressure. That's reving to 9k rpm as well, which eats up duty cycle fast.

In the end it's your call. If you need more than 1000cc/min you don't have many options. If you run these at high pressures you will make more power, idle and drive better, and get better fuel economy than any other injector that's over 1000cc.

Thanks for all your info Tony, both here and in PM's.

I'm not sure what my tuner will do but I know that my engine builder recommends going for 50PSI with my decaps. At that pressure, I may be on the verge of running out of injector with my setup so 100cc's (even though it's not heaps) would have been welcome. Having the other benefits of your injectors (like spray pattern for example) would have also been a bonus. It's only the fact that I'm putting on new fuel rails, getting a tune next week and coming across this thread that made me consider your injectors.

If I didn't have injectors, or if these flowed more than my decaps at "base" pressure, I would grab them. At this stage, I don't think that it would be worth it for me. I'll just see what we can get out of the decaps first.

The other thing to consider is efficiency. Better atomization increases fuel efficiency. We made 701whp on 4 of these at 50psi base fuel pressure, on VP Q16 which is oxygenated and requires about 5% more fuel volume than C16. This was on an S2000, which revs to 9500 rpm and eats up duty cycle pretty quick as a result.

How much power are you trying to make?

just ordered these injectors, and the wireless clips for my e-85 setup(stock 2.0, 20g). I really hope these are as great as everyone is saying, and I do plan to keep everyone informed as to how they perform in my car. cant wait

I just ordered up 2 sets yesterday. I'm switching from precision 1000cc to these injectors. I will let you know how they work out!

If anyone here is switching from your current injector to these Bosch, I would love to see a comparison dyno if you can get one.

I plan to a set of 1000cc Bosch injectors in the next few days. After my tune in a week or 2 I will report back. I am currently running RC Engineering 310cc injectors, so I doubt any before/after dyno charts will be of much use.
