High Impedance Injector 15.9 ohms
37lbs @ 3 Bar (Advertised Specs)
40lbs @ 3.5 Bar
Dynamic Flow (mg/pulse): 8.42
Spray Pattern: Split 20*

Bosch 35lbs Injectors (0280155737) - Ordered but not going to use.

High Impedance Injector 12.2 ohms
35lbs @ 3 Bar (Advertised Specs) but really 34lbs
37lbs @ 3.5 Bar
Dynamic Flow (mg/pulse): 4.83
Spray Pattern: 4-hole disc

Bosch 36lbs Injectors (0280155868)

High Imdepence Injector 12 ohms
36lbs @ 3 Bar (Advertised Spec) but really 33lbs
37lbs @ 3.5 Bar
Dynamic Flow (mg/pulse): 4.83
Spray Pattern: 4-hole disc

Bosch 42lbs Injectors (0280155968) - Ordered

High Impedance Injector 12 ohms
42lbs @ 3 Bar (Advertised Specs)
46lbs @ 3.5 Bar
Dynamic Flow (mg/pulse): 18.6
Spray Pattern: 4-hole disc

Delphi 42lbs Injectors (01D030x) - Thinking about getting these and selling the Bosch 42lbs Injectors

High Impedance Injector 15.9 ohms

Other important specs that are hard to find:

Injector Dynamic Response Curve

Injector spray cone pattern (Spray pattern: It usually has 1 or 2 "cones")

Injector spray cone angle (Angle or width of spray cone)

Injector spray cone bend angle (Angle of spray cone when compared to the injector body centerline)

Average droplet size measured in microns (Changes with fuel pressure, so it's usually a 2D chart)


Against popular perception, fuel injectors when installed in modern fuel systems don't deliver linear amounts of fuel. Even when they are held wide open, (100% IDC) there is deviation in flow, droplet size, and cone shape from millisecond to millisecond. Better fuel injectors show less deviation from ms to ms.

I will add what I can to the Tech Post Most of this stuff would have to be done with special equipment that i don't have...

I don't know of many people that have access to equipment that will provide that info. I just mentioned it from a technical perspective, not a "must have" perspective.

Or you could get it coated with Turbo X....but it seams a waste to ditch the swaintec coating and spend $500 on another coating that will do pretty much the same thing.

Nice build thread. I wish I had done one to document all the stuff I did from February through April. Spent something north of $12K so as you can imagine it would have been an EPIC thread.

Yeah, that's a lot of extra cash

Swain said it was fine to paint them with some high temp.

Hey Brady,

I did get your PM a while ago, just never got a response from Karl in regards to the transferring of the tune. But I don't see why it cannot be done.

Disassemble the intake to seal up the BOV and swap intake boot.


Fully Assembled for the Most part.


I also made a Metal Bracket for my Oil Catch Can today. Hopefully, paint it tomorrow and bolt it in.

Viral,

This is AWESOME! I am planning to come down During ThanksGiving Week. Planning on taking my little sister to Disney World. Would like to knock 2 birds with one stone

I drove it once already. Orlando is still FAR away from Active. Closer than Texas but still.

Although almost all is well...I still may join you. While Mayco did a pretty good job I would like to see if I can get things spot on. I do have this mystery crank, turnover, and die issue from time to time but my engine is still in one piece and that makes me happy.

Come on you know the drive from Texas to Miami was almost as great as your European Delivery . Glad to hear that your car is still in one piece buddy. When are you gonna come down for another road trip

Not sure exactly when...someday.

Anthony,

If you stay in Miami...I think Viral says any hotel with Miami in it is high class and recommended.
