Pretty much sea level around here. I don't need to search, I know what is proven to work for me. Again, nice numbers.

I have not tried racegas. I've scanned hours and hours of data on the car with multiple tanks on 93 octane. The most it has ever let me run with 0* KR was 24*. Let the motor get heat soaked a little and KR is picked up on another pass.

It doesn't make anymore power with more timing. The knock sensors do their job and bring it down to 22-24* timing when I bump it up so I do not hear any knock. AFR is 13.0:1. I am sure I could run more if I fattened it up, but I would not make the same power.

What kind of AFR and timing are you seeing on LS6 cars?

 

Ok. Awesome. Not looking to get into a pissing match here. It is what it is.

 

I'm not trying to tell you what is best for your combo, I was just intrigued about the difference. Sorry if it came across as bashing or something

good #s..
my car doesn't like anymore than 22* either,but it's also a heavy pig...
i wonder if the Fast would have done a little better with a standrd split cam?

 

My old Bolt on 2002 Z06 didn't like alot of timing either. I think it was around ~ 24 degrees. Nice numbers.

 

22 degrees is fine and within the typical 243 timing range. More efficient heads don't need lots of timing. Tests by myself and others have proven this many times.

Your numbers are similar to mine and I'm also not sure the Fast92 is really beneficial with our setups. I was trying to get an LS6 intake to test with but it seems more trouble than it's worth right now.

 

LS6 here... cam only, 26-28 degrees.

 

Did you tune it yourself?

 

No, Mike Norris in Florida did the tune. I remember he said that the car didn't like alot of extra timing, but HP Tuners shows it was still bumped 4-7 degrees at the top end (stock timing is about 22 degrees.)
