I also know they will make more because this chart is based on a 12 to 1 fuel mixture which is for turbo. Meaning NA mixtures wll be fine at a leaner 13-13.5 to 1 mixture. So the WHP on NA will be more.
im gunning for 250 (oviously all depending on cams in the end) thanks for the info.

Those injectors are probably either S15 444's or Nismo 740's.

Yeh, they kinda looked "brick brown" but they also look red. It says they're for S15's but I didn't know what CC they may be...or if they were maybe the 740's. It also say's they're 480cc....

I was watching these on EBay too!!!

They look like the 444s. I've only seen the 444 reds in person though; never actually seen the 740 reds firsthand.

They will advertise as 480cc's but they are really 444's. That Jap Parts Specialist company is good, i got my 444's from them. Just make sure they are genuine S15 injectors.

444's

740's are straight up Red. That is a brick color.

I think its about 13.35%, that makes 370s 427cc at 4 bar. 555s become 629.0cc using this same formula, I dont know if that is correct or not.

Dre, can you add SARD 850CC side feed injectors to the list? Here is a pic of them.

also the collars are needed for a direct drop into the side feed rail. Also you use the stock SR20 O-rings.

so if i put my 370cc to 4bar then it make the injector a 427cc ? so when JWT prgrams a ECU for a 4bar prgroam they are actually jsut saying it has a 427cc injector in it ?

If running at 4 bar helps atomization, then does it compromise the injector to run higher? I mean, any reason not to run 5 bar?
