Anybody using these? Will they support my build? They are listed as "Racetronix 42LB High Impedence Fuel Injectors (Flow Matched)" and priced $330. How do these compare performance wise to the FAST and other brands???

thanks

I can't speak for how they compare, but 42 # injectors will more than cover you.

Most people I know run green top ford 42# injectors.

42# injectors should hold 600 hp so yes

I got the white GM supercharged 3800 injectors. Cheap but effective.

I have the red top now and don't think you can buy the green top anymore....

Do you know the gm part number for those? and what is the flow rate?

They will work fine, but you don't need that big of an injector.

you shouldnt need that big of an injector for a non boosted set up

I had issues with the racetronics when trying to tune. bank to bank was off by 13%. Swapped to a set of SVO 39# right there on the dyno and the bank to bank was 1%. The SVO's worked fine for me and I am making 465 RWHP in 100 deg shop air.

Yes 42# injectors will be fine for your set up.

make sure your ECM is tuned for those injectors before fire up.
