heres my setup


im having a little trouble calculating my engine compression ratio.

i looked at different sites but they gave me different numbers maybe honda-tech can help me.


gsr block
.25 over
ctr pistons
eagle rods
arp rod bolts/ headstuds

b16 head
full port and polish
dual valves and retainers
flat faced high rev valves
sk2s2 cams
itr manifold
itr throttle body
jdm itr header with heatshield for cops purposes
aem intake

nitrous ports hidden behind the intake manifold 100 shot

oem headgasket


gsr tranny stage 3 4 puck clutch

this is my daily driver and been driving it for a while now on 91 octane gas and its been running great. i just want to figure out my compression ratio. im thinking its around 12:5

p.s. i have aftermarket intake manifold/throttle body and a hytech header but cops in cali are pigs so i like to keep my motor stock looking. haha and my car is B.A.R. legal

let me know what you think

sorry i was rushing. what i meant was the ports are mounted behind the intake manifold

As in 2 nozzles into the plenum itself?

norcalbayboy

yeah

So let me get this straight and I'm sorry it's off topic of your CR question:

You have 2 wet nozzles placed somewhere into the plenum of the ITR manifold, each jetted for "50"? Has this car ever been sprayed? Does it still run? Can I see a picture of that?

ill post a pick later today when i get of work

but besides the nitrous setup hows the motor setup and if you know the compression ratio that would be nice too haha

CC'ing is the only way to determine. I think it's closer to 13 then you think, but I can't see the chambers. You can't possibly be spraying that motor the way you are on almost 13CR with 91pump.

Still in for that nitrous setup picture.
