Hi,what size spacers do we need for this injectors? Thanks for the part#

 

Do you need a tune with those, or is it a set up the computer could adjust to?
think these injectors, C.A.I. and 74mm throttle body would be a decent set up?

 

The injectors, cai and the TB would be a very good setup with a tune. The only time bigger injectors make more power is when the stock ones are maxed out because of changes in airflow. The intake and throttle body will flow more air through the motor, the injectors and tune will give you a better air fuel ratio.

 

Thanks for the part number Chuck...

 

BIGGER INJECTORS ARE NOT NEEDED.

I went from 17 to 1 f/a ratio to 9 to 1 just be changing the rail pressure.

I did a big writeup showing the results and method to increase the pressure. THe stock regulator has a port that will accept a pressure signal and increase the rail pressure.

I went to 80 psig rail on 20+ psi boost, way too much.

Fuel falls off with higher boost due to the INCREASED boost PUSHING against the injector DECREASING the pressure differential. At idle the 58psig fuel rail is aided by the -10 psig of the intake manifold to give an effective 68 psig differential.

By adjusting the rail pressure I have been producing f/a ratios of about 12.7. I control that DYNAMICALLY by monitoring the f/a ratio WHILE DRIVING with a add on computer. See my signature for coming events............

YOu dont need bigger injectors and I have been to 25 psi boost ratings before I ditched the code three / 178 and went to a STANDARD 185 eurocharged pulley.

The injectors are for naturally aspirated crossfires with intake mods. I calculated 19.4 #hr injectors are needed for 215hp at .80 duty cycle and .50 BSFC and 58psi fuel pressure on
http://www.rceng.com/technical.aspx
The OEM injectors are calculated to be at 100% duty cycle to produce the factory advertised 215 hp, IMO this is why the stock xfire falls flat in the upper RPMs. My car definately pulls harder from 4000-6200 rpm after switching the injectors.
The calculator may be off but I believe it to be accurate.

 

Did you tune your crossfire or is it still have a stock flash?
