Nitrous experts help?
I was just wondering what air/fuel ratio you guys are running with what set-up?
The reason i'm asking is because i'm planning on running a ls/vtec with the following set-up...
Bottom end:
eagle rods
srp pistons(81.5)
GSR block girdle
but it is going to be with stock sleeves....*crossing fingers* hope it holds up.
Head:
P&P GSR head
Skunk2 manifold
REV valve springs and retainers
REV valves
not to sure on the cames right now...trying things out..
oh yeah, compression is going to be from anywhere from 10:5 to 11:1
Planning on squeezing a 50 shot fogger off the line then somewhere from 80 to 100 direct port.
any info would help!...

on the bottle you want to be slightly richer than an NA car but you dont quite have to be sitting at 11.0:1afr, any where in the mid 12s is okay.
as far as timng goes, i dont what management you are using so thats a tough one.
if it were with a stock ecu i would come back 1-2 degrees for the 50 and then another 2 degrees for the 50 and if you were on a hundred shot instead of the 80 add another degree as well.
so 50+80 i would use 5 degrees
50+100 come back 6 degrees.
use some 7 series NGKs, get some good gas and make sure the regular maintenance things are done like cap, rotor, wires and such.
also if both of them are ognna be "t'd" into the factory line i would recommend you bump up the fuel pressure by about 5-8psi.
the car may run a little funky all motor but it will run like a beaten dog on the bottle.
i had a 2 stage on my hatch before.
you just cant beat the pull of 2 combined nitrous kits.
i recommend 2 seperate lines and 2 seperate bottles.
and please tune the car wit the same bottle pressure in each bottle.
975psi= good

i sprayed a 45 dry and a 90 wet. i only ended up using the 90 wet cause of time constraints and i was a little "skeered" haha. but the wet kit alone on the gsr hatch was good for mid 11s.
if ya need any help let me know
