General Timing examples on a 90 lb/min plus car???

[spoolinpos]

Hey guys, I'm just looking around for some example logs (ECMLink) with a car running in upwards of 80-95lbs/min and the timing seen at higher rpm? If you're seeing 45-50psi and seeing a flow of 85-90lbs/min, what is a round about timing you go to? (assuming E85 is being used) Thanks!

Not quite in your league, but when I was running 45lbs on my HX40, I had a max timing of 18*. I started at 15* and moved up 1* at a time. I didn't see a difference between 17 and 18 so I backed off to just 17*. I was only flowing a little over 60lbs/min so it may not have the correct info you are looking for but that is what I was able to run.

14* is where high boost setups make good power

I'm on 94 pump + meth but I was at 13° peak timing at 75lbs/min ~42 psi

Compression will play a factor here 8.5 vs 10.5 but 12-14 degrees at 50psi is gonna be in the ball park.

Would need to know compression ratio. Reading plugs can really help finding out what the motor wants. My 10:1 motor as been above 70lb/min and i think i started at 8-9 degrees up top and worked up to 12-13 degrees. That much air flow would be best to use a dyno and read plugs to find what it wants.
