high comp bin?
anyone have a basic BIN file for 11:1 ish compression ratio and 4 bar fuel pressure 370cc injectors? im trying to figure out what the exact CR of n1 pistons in a bone stock high port is.

bump bump.

370cc
4bar
11:1ish compression

Firstly, why so much fuel? Secondly, you need to specify the MAF for the bin file. Thirdly, how will that help you determine compression ratio?

I have one for stock maf stock injectors at 3 bar..
I think 370 at 4 bar its totally unnecessary..
If you are interested let me know..

i believe n1 pistons have the same cr as 16ve pistons, so 12:1. only reason why n1's have higher compression is n1's have a shaved head.

thats what i thought as well. actually the sr16ve pistons will be slightly higher then the N1 pistons.

all i have heard is speculation over the N! cams true compression ratio in a DE. so i have decided to play it safe and use standard 10:1 pistons.

i want the correct amount of fuel sprayed but at a higher delivery pressure. i have read plenty on the forums suggesting a 4 bar program atomizing the fuel much better and providing more power.

yo pete let me know what maf your running and gimme an email address i'll send you a bin

If you make more power beyond the error factor of the dyno simply by going to 4bar, I would be amazed.

im not saying i will, i have just read plenty of info on a 4 bar setup being better than stock......3bar? and i have a nismo afpr laying around and figured i might as well do it.
