hi,
i was about to buy a set of the 2000cc injectors but i have just had a conversation with a friend who already runs them.
he had put 4 brand new id2000 into a circuit car that runs on a pump gas/ ethanol mix. the car tuned up well for the first hour on the dyno. then some issues started coming. he spent another 4 hours on the dyno with the problems getting worse and the car getting leaner and leaner every run even though more fuel was being added in the fuel map.
he pulled the injectors and put them on a flow test bench and found they only flowed around 1600cc now(they flowed over 2000 on his machine when new).
he had a similiar problem tuning another car couple weeks prior so pulled the injectors out of that and they were way down on flow as well.
he has checked for mtbe in the fuel and the data sheet says there is none.
is there something else the injectors are not compatible with?
have you heard of any similar problems?
cheers

hi again,
did you end up talking to injector dynamics about my friends problem?
i have talked to him again and it seems some rochester injectors he is using have done the same thing(down on flow after a day on the dyno).
obviously there is something going on with his setup. it seems strange as the car has had indy blues in it with no problems so far. i will talk to him more and try get to the bottom of it to appease my curiosity.
i would be interested to hear what inj dynamics may think the cause could possibly be as it seems there is something that isnt agreeing with certain types of injectors.
cheers

You can also ship them to us, we can take them to ID directly and have them inspected. We will still need to know the original seller, they will have a s/n number but we want a verbal verification as well. Many fakes on the market, not to say your friends are but more info the better.
Thanks

ok cool. i will ask him where he got them from.
when you say fakes? what would be different about them? the number on side has been ground off i think. i thought the id2000s were factory bosch injectors that they test and batch so you get a complete set suited to each other and added the filter extension piece. i never realised they modified them at all.
he doesnt want to send them back to injector dynamics as we live in new zealand so freight is unneccessry expense.
i too told him it can only be mtbe but BP are telling him there is none in the stuff he is using. i was curious to know if mtbe is the only thing they arent compatible with?
hmmm, i wonder if they are fakes, that would suck! didnt know people were making fake injectors.
i will talk to him again on the weekend hopefully to get the full story.
thanks for your help.

If the same thing has happened with Rochesters, it is unlikely it is MTBE, and more likely contaminants getting into the injectors and slowly clogging them. How do the pre-injector filters look on the ID2000's?
I'm not sure what E85 on your side of the globe has in it, but over here, we've had some strange gum-like build up that can stick injectors.
There are a lot of guys in NZ running similar setups and this is the first issue of this kind I have ever heard. T1 Race Development (Distribution side of Injector Dynamics) would be the best to contact next if his dealer can't help him, and then we could check them out if necessary.
The 2000's are unmodified, but as you stated, tested and matched into sets based on flow and dead time. Other models in the lineup are modified however. There are other companies selling dynamically unmatched injectors that claim they are ID or "same as ID" injectors and have even copied our data to use as their own.

thanks for the input 2a+ron.
he has checked for contaminents and is confident it is not the issue.
he isnt running e85 as such as it isnt the easiest to get here, he is mixing 98 pulp with straight ethanol himself. as he has had the same problem with another car running a different brand of pulp but same ethanol he is going to look into the ethanol he is using and the way he is mixing it.
at this stage i think the most likely cause is gumming up the injector with somethingin the ethanol, he is going to try cleaning injectors and see if he can get them back to life.
i have told him to get hold of the person he bought them off and send them back to be looked at, so he willl hopefull decide to do this.
thanks for the help, i will fill in the outcome when there is one.
out of curiosty, the car i will be putting id2000s in is a straight methanol rotary, we currently flush the bosch 1600s with petrol if its going to sit for a couple weeks so they dont stick shut, do the id2000s require the same maintenance with alcohol fuels?

Ahh, yeah I think there must be something in the ethanol he is using, nothing else really makes any sense.
We do recommend a gasoline flush with ID2000's if the car will sit, as we have found some sticking with alcohol fuels as well.

I talked to Tony at T1 awhile ago on why they don't recommend running Q16 with these injectors. He said that the seal inside the injector will swell when exposes to MTBE restricting the fuel flow to approximately 1600cc. He said that you'll be fine on the first few pulls, it will slowly lean out as the seal swell up. Whatever it is, it sounds like the seal swell up.

Yeah, as 2A said before it swells upon contact with MTBE containing fuels. If for some reason their ethanol (E100) is mixed with 15% Q16 (MTBE containing) then it is probable, otherwise it is more than likely contaminant based. On a side note the swelling subsides when the MTBE is taken out of the equation, so if they are reflowed they should once again be back at ~2200cc/min.

Glen,
Could you please comment on the fitment problems/concerns on the second page of this thread.

I called T1 and didn't get much help on the issue, thanks.

I know commercial ethanol has a tiny percent additive to keep it all in suspension and not separate, so perhaps "home-made" stuff without that reacts different... and with 98 too. The prefered mix is 95 so there isn't horrible aromatics in the equation also.
Odd that it happened with Rochesters too, wonder if the Premix is common between both projects.

yeah we did wonder about the premix but came to the conclusion there was nothing in it to cause this. anyhow the injectors have been sent back via the dealer i believe so will find out soon enough.
