Just wanting to know how many people out there are running 550cc injectors?


"Spent way too much to give up now!!!"

I have 60#/hr siemens deka's



99 Turbo Sunfire GT | Ram 2500 | International Rollback | Mr Hanky the Suburban

that's a lot of fuel for a Jbody




I was a retard, and now I'm permanently banned.

I have 450's in the drag car, with a 5:1 FMU....




SPD RCR Z - '02 Z24 420whp
SLO GOAT - '04 GTO 305whp
W41 BOI - '78 Buick Opel Isuzu W41 Swap

yeah thats alota injector. I belive that dj suncavi and hypsy are running no higerh then 450 and there the fastest streaables on hear (i dont wanna hear @!#$ about the portfuler you bloodytampons.) so I would doubt you would need a 550. untuned you just reroute a hose back to your gas tank from your echaust pipe and get all the unbernd fuel. so go for it.

550cc is a lot of injector for your car... the 310cc ones that come with the GM supercharger kit max out around 210-220hp at the wheels... so 550's would be like 400+hp .... i would say go no more then a 440....and even that you will be running nice a rich.. i think my buddy has 370cc on his turbo 2.4L and he still runs really rich... to the point where he gets like 200km's to a tank of gas (still tuning it though)
