Mods are in sig. I am spraying 150 shot with br8efs plugs with 10.5 com ratio with 91 oct. pump gas (12.7 afr ). Does 22* sound like too much timing for my app. I am learning to read plugs I think i am getting close. Am I in the ballpark? Where is it normally for this combo? For example would it be in the (16-18) (18-20) (20-22) (22-24) range? I know every motor is different but when you do this all the time you know about where it will end up. So could you help reassure me i am not way off. Thank you.

Do you have pics of your plugs? 22* doesn't sound bad for what you're doing, but by reading the plugs the motor will let you know what it wants. If you have pics of them, post them up and let us take a look!

It was good talking to you again and as per the phone conversation you're in the right direction but we do need to get a good read on a fresh set of plugs to ultimately determine where we on the timing mark.

Fot reference with my TMS motor I'm at 27 degrees timing n/a, and 23 on a 125 shot. That's what my setup likes

I will try to get plug reading today or tomorrow. I appreciate the quick response, I am close.

i run br9s, 200 shot at 11.7ish afr on the bottle, i run 23 degrees but i have a stand alone fuel cell for the nitrous kit that has c16 in it. I never burnt a plug and the strap looks good

I bought a 10 pack of plugs and was wanting to check plugs when the rain came in. Maybe tomorrow.

I am running lean using .062N .031F (plugs are reading but the wideband reads 12.7-12.5 at start of run and 12.2 end of run) jets the kit recommends is .062N .036F if i run recomended jets the wideband reads 10.8 to 10.5. That is why I started messing with the fuel jets next time i am out will get a plug reading. Do you vary from recommended jet sizes usually to get it dialed in? I am using a shark nozzle (58 ffp).

This is exactly what happened to me when I ran the recommended fuel jet for my 125 shot. Now with a 57/27 its about 12.2 a/f on nitrous and 12.9 n/a

Chris from NX, the nitrous jet sticky says .033 for fuel but your website says .036 for fuel on a 150 shot which one is correct? I have a (.033 and .036) I am going to try next time out. And the BR8EFS plugs are working.

You can't ever go by the manufactures jetting. I usually just make one pull with whatever hey suggest. Then go to adding more nitrous lol

Exactly!

The 33 should be ok for you to use.

From what i am seeing I will probably end up with a .033 I hope to test today.

ejbta2

Well

.062N/.033F is where i ended up. I think my plugs look good. Here are some pics.

ejbta2

Well I ended up at a 11.5 AFR on my wide band for my plugs to look like this.

Is there any kind of idle time/ drive time on these plugs or is this after a full hit with immediate shutdown of the engine?

-Chris

1/4 mile pass immediate shut down.
