The time has come to upgrade injectors again and im not sure of brand or size to get, I have 550cc ones now and am out of fuel at 340rwkw, I want to see 400rwkw as a minimum shortly but I dont want to have to change them again if I get a rebuild and try for more power. Any help appreciated, thanks.

any help at all?

hey mate for 400rwkw i would probably go 1000 cc as at around 75% load cycle you could make that power and go all the way up to about 530rwkw at 100% load cycle 800cc injectors would pull 430rwkw at 100% load cycle so might be a bit small 850cc will make around 450 rwkw at 100% 900cc will support 475 rwkw at 100% 950 will support about 500rwkw at 100% hope this info helps i think your tuner will probably have the best idea though

Thanks mate, just what I was looking for. Spoke to the tuner he said 1000cc injectors but it always pays to get a few opinons. Cheers

Next question, who is using what brand 1000cc injectors? and what are they worth?
