Just wondering what you guys think I should shoot for.

I have the LC-1 Wideband, 100 dryshot I usually try to keep the bottle @ around 900-1000 psi to keep the initial hit from being too hard.

Right now I am right around 12.5.

Is this too far on the edge? I am basically using the PE mode to richen it up over 3k which is where I spray.


Please guys tell me your thoughts

 

Come on this is an easy one. Little help?

 

11-12 a/f. i try for 11.5. you can go leaner but the hp isn't worth it for me if it's even there.

 

I am getting no knock at 12.5 but it worries me since most say what you say?

Has anyone spray 100 @12.5 for any substantial period?

 

in my opinion that is too lean, mine on the 100 shot wet, 950psi is 11.5-11.8. Its 12.8 on motor.

 

Thats really lean. As stated before, I'd shoot for a target range of 11.5-11.8 AFR

 

I shoot for 12.7 on motor, and 11.5 on spray. I'll drop down to 11.2 on a 200 shot though.

 

Im at 12 on a 100 dry shot.......some say its not rich enough but its fine for a 100 shot.....

 

Just get good practice on reading plugs.

 

Re tuned it for 11.8 on spray, still pulls almost the same and added piece of mind


Thanks for all the replies guys.

 

11.8AFR is right where you want to be....Time to let it eat

are you suggesting a 175?

Im still on stock clutch so it might be an exercise in futility.

 

Yea, a stock motor and a 100 shot the cylinder pressures are not very bad. So, you'll likely cause no harm. Some would consider this the edge, but IMO, hardly. Hell some of the record times I was setting in the Z06 stock LS6 with a small dry shot were this lean and leaner. So, it really depends on your comfort level and I like tuning to the "edge", but also understand the ramifications if something goes wrong. This is where it gets personal choice, running this lean you have removed a nice safety net compared to a 11.5:1 ratio, so if you have an issue elsewhere would your motor survive? Probably would, but can you afford this if things go wrong and you need repairs? I always new i could eventually blow my motor, but that was my goal from the beginning to see how far a stock motor could be pushed, and i will tell you these LSx motors can handle a lot of abuse (old threads can give insight on my stock motor). Now with all that said, if you can, get it into at least the high 11's.
