Bosch 1000cc injectors on an Evo
Looking for some feedback from folks who are actually running the "Injectordynamics.com" Bosch 1000cc/min injectors on an Evo. Honda guys have been running them for a while but haven't heard much about these on an Evo.
Any impressions regarding idle quality on gas, part throttle driveability?

I have no personal experience with them yet (although tempted to try them). As you said honda/ acura turbo cars have been running them with great results thus far. From most of the feedback in those forums or some other forums where they have been tried, the first thing the tuners are saying is how nice they are to tune with.
More than a few well know and respected tuners with proven records in that market have posted saying its like tuning on a much smaller 600cc saturated, much better idle quality, very noticeable improvment driveability, battery comp values are supplied with them, sets are matched, better atomization/ droplet size you usually cannot get from a an injector this size, supplied with adapters/ injector clips, etc.
From Tony Palo of T1 Race Development:
"Here are some advantages:
High Impedance, no need for injector drivers or injector resistors
High pressure capability, All injectors will run comfortably at 100psi above 10v, flow will be increased by approximately 50% at 100psi
High duty cycle, with a recovery time of only 1ms, all injectors will run up to 92.5% duty cycle at 9k rpm and 95% duty cycle at 6k rpm while maintaining linearity within 1%
Excellent low pulsewidth response, linearity within 2% all the way down to 2ms, predictable response down to 1.5ms. Using a 3 dimensional battery comp table with Motec V3 software, low pulsewidth response can be linearized to practically zero flow.
Good atomization, Droplet size of the 1000cc injector is comparable to the Siemens Mototron 60lb injector, and is far better than the Multec 95lb, Standard Motor Products (RC) 1000cc and Siemens 72 and 83lb injectors.
Excellent consistency, no sets will require more than a 1% trim
Ruler flat response, unmatched linearity means easy tuning and accurate compensations. "

They wont work, because the stock evo has low impedence injectors. Its either the ecu can work with low impedence injectors or the evo has a stock resistor box on it. If the car has s stock resistor box then find a way to get rid of it and you can run these injectors.

So do we know for sure if it has a resistor pack? If so, where is it?
Since I use to be a regular on Honda-Tech, I asked tony if he could post here for some info for us.

Hi guys,
For starters, these injectors will work on the evos. The stock injector resistor will need to be bypassed (very easy to do). The stock injector drivers are not peak and hold drivers, that's why there's a resistor used with the low impedance injectors.
Here's a pic installed on Forced Performance's EVO. Scott had nothing but good things to say about them and was also kind enough to share the necessary lower oring for a perfect fit on the EVO.
We've been using these for some time now and everybody has been blown away with the performance of them. We have quite a few big and well respected tuners in the industry who have been completely sold on them after tuning with them, including myself. I can promise you there's not another 1000cc injector on the market that compares.
Check out www.InjectorDynamics.com for some pretty detailed info about what goes into these injectors. The "questions answered" portion has some very interesting info as well. If you don't learn something from that site then you're either way too smart or too dumb to comprehend. lol
There's some more info, pics, dynos and a datalog on my site about these.

If anyone has any further questions, ask away.
