Hey check these numbers out and let me know if im ok as far as A/F ratios go.........this chart is with my 55 jets in...........when i run my 75 jets do you think the ratio gets leaner?

 

this chart is with NO NOS, just MOTOR.....ratios are close to the same .5 higher running nos...........let me know....THANK you

 

Did you spray through the hole run? They look ok to me, check your plugs is what I would do.

I don't trust the Dyno Jet A/F numbers and when you change jets of course the numbers will change.

I think you could go a little richer on the fuel side with a 75 shot, looks like he backed off at 6k but it was staying rich at that point, I have always been told "better rich than lean" when spraying.

I pulled my pkugs all the time after dyno's when I ran N20.

I will try and find my 75 shot Dyno Jet page

 

You have almoust perfect A/F ratio w the NOS 12.0 - 12.9 range is very good... I wonder how come your car still pull the peak HP up to redline? my car have the peak hp on 6000 after that goes down a little bit and also the mix to 11.6... the only thing is that you have 75 shot but only 30 hp on the wheels... this is another case of underated jets!

the weird thing is that on motor you end up with 11.8 a/f mix... is the first 350Z that put that mix up to redline (at least that I see)... everybody else have 12.0-13.2 range on motor only!

 

so guys..........what zex jets should I use to get 65+ RWHP and still be around 12/1 A/F? Would I need to adjust my timing at all and or Different Plugs.......and by the way how the hell you get the plugs out, I cannot even see them................Thxs again guys, the more info the better, Ima newby, but willing to listen and learn....

 

You have to remove the CAI to get to some of them PITA. You have to remove the coil packs then they are under the coils.

Yeah get some NGK one heat range cooler plugs they are cheap.

Also try some NX jets I didn't have any type of accuracy with the 75HP jets and they told me they didn't make any bigger jets for my kit (at that time.) You are dang near perfect go do a run and see how you do first bro!! 15 bucks!

You probably want to be somewhere near 50 and mid 20's is that time in your sig with this setup?

Edit add there is a place called Tea Garden Motor Sports in Rancho down the hill from you that sells any jet I ever needed just call ZEX and tell them where you want to be get the 2 numbers then call Tea Garden and see if he has them!

 

Thxs bro will do..............yes my time in my sig is with the 75 jets...........changed back to 55 after i raced due to my FEARS!

 

Break 12's just stay slighty fat no fear.

 

for scuba. A/F at 55 shot
