Check out these 60pph Hi Z injectors...

Anyone have any input on these? Chip makers? If these are a good idea, I'd get them instead of the 57's when I buy in the next month or so...hmm...

It's right at $400 total after s/h and everything, where I can get a set of used 50#'s for $300 total..is the extra 10# worth the price? Is there much safety in that extra 10#?

The Racetronix 340 kit is enough to supply these right? Just planning on mid 11's.

They are neat.
I just got to dialing them in when the freezing weather hit, but they are just short of incredible. On the ecm bench I had them operating down to .6 msec PWs. and in early idle playing around with them had them down to .72 and the engine idled just fine.
Those PWs obviously were in a batch fire system. So in a SEFI they should be a no brainer.

I'm sure as the warmer weather gets here, there'll be alot more talk about them.

Just remember if your going to use them to have your fuel system up to snuff.

Wow those are nice. The stock ecm E.T. is getting lower every season around here.

Do they seem really long or is it just me?

Isn't turbolink a Mosher company?
Sounds like he found an injector that everyone else did not see available for our cars.

Lookin forward to hearing more about these and chips for them.

These injectors have been around for a while now. These injectors are Siemens Deka 4 Series made custom for Mototron. They do not come flow-matched from the factory.

Yes thats kens company. Good guy too.

 

[GNVYUS 1]

Racetronix, are you able to carry these so that we can get them matched?

 

[Racetronix]

We are working on larger hi-z injectors as these are too close to the 57's to make it worthwhile.

 

[Adrian87]

What are you guys working on and when would it be available?

Other then just throwing it out there, can you document that as being a problem (with these particular injectors)?.

They are thin in the main body area, so they give the illusion of being longer.

The merits of flow-matching injectors has been discussed in numerous threads on this forum. Please use the search engine to find threads which cover this topic in detail.

Siemens +/-5% tollerance applies to these injectors unless stated otherwise.

As soon as we have any info on new product releases it will be posted on the Racetronix web page.

i have some 50s flowmatched for sale soon
$300 shiped low miles

Gotcha Racetronix, makes sense if you have bigger ones coming out. With the new Garret wheels out and bigger high z injectors coming, we might see a low 10 with the stock ecm this summer

Doesn't +/- 5% seem a bit much for a tolerance on an injector?

I flowed my 36's at Caspers and they were within 1.5% of each other.

The 60's run great. I have them in my car now. Tip-in response is great. Haven't run into any problems. Yeah they look kinda funny, but they fit in perfectly. So far so good!

To my understanding, at least some injectors are flowed at the factory. Whether this is true of all injectors from all manufacturers - beats me. If and how injectors are grouped by the factory, and the resulting tolerances are also not clear to me.

However, the above makes me wonder if there are any advantages to repackagers reflowing injectors. For example, do they achieve tighter tolerances? Are tighter tolerances meaningful in the real world? And when they are reflowed do they achieve the same base results as the factory, or is there a difference between machines ("a man who wears 2 watches can never be sure of the time").

Regarding reflowing, I don't like paying for something that's unnecessary. Nor do I like taking the risk that something will get FU'd in the process. Not saying that will happen - I just don't know.

Where's it stated that Siemens uses a +-5% spec?.
If your throwing the claims out there, it's your responsibility to document them.

 

[bruce]

While they're not too much larger then the 57s, like I said the low PW operating of them is much better.

The next size larger is guite a jump from what I've heard, and really gets into fairly radical engines to capitialise on using them, IMO.

Like I said before... flow-matching is an old subject and its merits have been long proven. To debate this topic here is silly. If you do not believe the Siemens spec call them yourself. Delphi has the same spec as well. All factory injectors are flow-tested to ensure they fall within the factory spec. and that there are no duds, leakdown problems etc. They are not flow-matched however. Flow-testing and flow-matching are two different things.

One man wearing two watches who is unsure of the time can always get a Cesium or Rubidium standard calibrated to the NIST.

I don't think it's silly. Besides, it's February. If you've got a few minutes, please tell us what you do when you receive a box of "factory tested" injectors.

Thanks.
