Cleaned Fuel Injectors

Clean fuel injectors are always good. Not only from a performance standpoint, but also for a keep from burning a hole through my engine one. Over time, or even out of the box, your injectors can get clogged and are flowing less, dripping, or even having a very poor spray pattern. If they get too restricted you can run lean and then melt things. Before you do any modifications raising boost, cleaning/balancing your injectors should be done. Because I plan to sit around 12PSI I decided to stay with my stock injectors. So I got an extra set, to avoid down time, though it is very short, and had them sent to RC Eng to be cleaned and balanced. The cost is around $135.60 and as a SoCal Supra's member I got 10% off.

When I got these injectors back, I swear they were done the same day they received them, they looked very nice with new O-Rings and a technical description of the before and after. I don't have a technical install section cus they were put in as part of my head swap.

Before Cleaning:
Inj CC/min Pattern
1 435.0 Fair
2 442.0 Dripping
3 451.0 Dripping
4 440.0 Good
5 446.0 Good
6 447.0 Good
System Balance: 3.7%

Dripping is no good, but these aren't the ones in my car. It will make me feel better when I do the swap though.

After Cleaning:
Inj CC/min Pattern
1 448.0 Excellent
2 449.0 Excellent
3 450.0 Excellent
4 448.0 Excellent
5 450.0 Excellent
6 450.0 Excellent
System Balance: 0.4%

Much better. These should give me more power, well give me power back, because of a better combustion, and give me confidence to raise the boost.
