Pretty much. We are the extreme minority of the quality fuel injector market, ID doesn't care about poverty people.

 

running a 240rwhp miata with 1000cc injectors is not the correct way.

they might be the best injectors, but that's not correct.


running a 240rwhp miata with 550cc ID injectors WOULD be correct.


hell running a 1.6L turbo is not even correct. Mikelly, nor myself, will ever come close to maxing 1000cc injectors, let alone 725cc injectors. And if running 1000cc injectors causes bad idle problems in his case, how is that correct?

just because the solution works for you, does not make it the universal solution. I have no problems suggesting the 725cc injectors, however.

 

Well Mikelly was originally looking at DW700's, which will idle like complete crap on his setup. I 100% will say that ID1000's will idle 10x better then he will ever get those DW700's.

So in his case the ID725's would be the most comparable to the DW700's. The problem is that I do not think there is a price difference between the ID725's and ID1000's and if there is it is extremely minimal. So do I spend the same money on smaller injectors that will idle the same as the larger injectors?

 

because there may be a huge difference in how well his old MSPNP on his batch injection might be able to control/handle either injector...regardless of the trivial cost difference.

 

hey trey, any chance you can post a picture of one of the tips on the five 0 injectors?
I am curious how they do it as the original cap is laser welded.

 

Scott I appreciate your weighing in on this issue.

Guys I asked about injectors and regulators, and appreciate all the perspectives. I want to make sure the "right" parts for the right current setup will work the best. I have no problem spending $450 on injectors. I have a big problem spending that money on injectors that will make this car run more poorly.

the 725s will be good. I've tuned shitty old 550s on MS1s and they could idle just fine, but those required slightly richer idle...around 13.5-14.

 

I guess the atomizing plate on the stock denso injectors is designed to split the flow in two and direct it towards both of the intake valves.
Modified injectors will not do this. Also my guess is that the ev14 injector atomizing effect will be superior when the Bosch atomizing plate is left intact.



For me modified injector solutions look silly. It makes more sense to get an original Bosch part that would suit the application without having to hack the most critical and precise part off. This is especially true when you look how inexpensive suitable original injectors can be got for. Ford Racing 47lb Fuel Injectors - Set of 8 - Home for your Ford Mustang
The ev14's in the link (part 0 280 158 117) are rated at 525 cc at 43.5 psi (615 cc at 60 psi) and cost 30$ each delivered.

 

Injector Dynamics doesn't use the plate.
Are you saying they are inferior to your cheap bosch injectors?

 

I never said anything about ID being inferior to my cheap bosch injectors?

From what I can see, at least ID replaces the atomizing plate with a cap orifice which may explain if the performance of IDs is better than other butchered injectors.

What I'm saying is I would prefer an original unmodified bosch injector rather than any aftermarket modified one sold at the same flow rates.

 

I have ID1000 injectors, Deatschwerks DW300 pump, stock NA fuel regulator (90-97) and stock 99 fuel rail.

So, you don't need an aftermarket regulator, really. I plan on getting one anyways, but simply for E85.

 

Sturvo, have fun buying two dozen injectors and having them all flow-tested so you can get a set that actually flows the same at both high and low duty cycles.

 

Andrew, is it necessary to flow test brand new unmodified bosch ev14 injectors as you are suggesting?

 

yes, and that's what ID does.

 

Interesting. So ID flow tests the injectors before their modification?
In my experience stock unmodified injectors are sold by the piece and do not have any "Must flow test before use" requirements attached.

 

...which is why ID's testing and matching process produces a superior product.

This really isn't hard.

 

Do you really think that modified injectors perform better up to the flow rating of the stock ones they are based on?

 

yes.

 

Scott, care to elaborate?
