Has anyone tried these yet, how are they with idling, tuning, etc.....

This is the highest you can go with the high impedance.........

I might have to get these if the 42.5ers don't cut it.............

They would be on top of whats in the sig now, but with twin 340's in the tank.....

Get them. I'm glad I did. But, you will probably have to put some more effort into zero'ing LTFT's and getting your RPM/PE table locked down. But, if you need more fuel, it's worth it.

We can get 60 hi impedence

really, how much do they go for? And will they be ok with a good edit tune?

The Mototron 60# injectors are not flow-matched.
If you are making enough power to justify a 60# injector you had best make sure you get a flow-matched set!!! At this time there are none to be had...

Racetronix's, Are your 57# injectors rated for 57 at three bar or the LS1's 4 bar system. Do we buy them straight from you and how much do they run??
How much RWHP are they rated to? Thanks

The 60# injectors are working great for many people. They have been fairly easy to tune and idle good. Shoot me an e-mail and I can get you a good price.

i haven't seen or heard any problems with the 60lbs injectors. The Only thing i do hear about them is how easy there are to get to Idle and tune

i have someone flow testing my 60#'s currently and will see how far they go on the new combination... we are hoping be able to provide matched sets of 60's to the public possibly this spring.

Whats the downside of the injectors not being matched?? What will it do or not do?? Will it hurt anything. Nate you have a PM.

There is what the manufacture considers to be an acceptable variance from injector to injector. In most cases this is +/- 5%.
It is not uncommon for us to see a 7% spread when flow-matching injectors here. It is a crapshoot when it comes to buying non-flowed injectors. If you end up with a few that have a wide variance it can make tuning more difficult and create drivability quirks. If you want max HP from your motor it could mean that a unknown number of cylinders could be leaning out before all the others causing the motor to knock which in turn retards the timing and would have to be detuned = loss of HP.

FYI the Mototron injectors are made by Siemens which are a new Deka series / type.

I was talking to the other Nasty, sorry for the confusion....

I have a set of their 57#ers and they are absolutely awesome. Tuning was a breeze.

On the note of flow matched injectors, think about this, the LS-1's are notorious for popping the back two cylinders. Would you want injectors flowing a questionable amount of fuel to them? You can also build more power, and have a better idle being flow matched as each cylinder will have a much more similar amount of fuel being delivered. Not bashing the 60's you guys are talking about, i looked at them too. It would just be nice if Mototron took the time to flow match them like Racetronix does. That's all.

Flow matching is good idea, as stated #7 and #8 tend to run lean. My 50 lb injectors were flow match and a I got the flow rate of each injector. I put the two largest flow injectors in the back so they would run a little fatter. We are only talking a little difference but at least I knew what I had.

If the injectors are flow matched then why would there be enough variance to provide for selective cylinder placement assuming they are a matched set and not just flowed?



Our import dealers specifically order injectors with a 5-7% variance to address cylinder to cylinder A/F / EGT readings.



Too bad domestic dealers do not figure this out and take advantage of the technology / product at hand to maximize performance...

Too bad you are not helping the lazy Americans. Seriously, post up...feed us....explain...tell the LS1 public so we pressure the dealers...and you...sell more stuff.
Thanks for the input, as I for one, will stay away from non flow matched for now.

Yea, I think I might go with the 57#s.......my old motor went because of #7........
