weak BAE5 screw converter setup

Made some laps with our promod 2437lbs C rotor @107% 4.86 rear,1.41 low ,Chance NXS 35/35 Bruno with mods.
3600 ft air produced 3.95 185mph .99 60ft and 2.62 330. The worst part is the rpm dropped 1700 shifting at 9300.
GPM,EGT, boost and timing were all set to run decent. Full 25 degrees of timing in at 1.7 seconds.Even started opening jets down low.
We tried rich/lean timing, new crank trigger,different stator cap. 183-185 mph was it.
IMO it should've been an animal.

Thanks for any ideas.

 

See your PM's.

The car looks weak at 60' and really weak at 330'. The split from the 330' to the 660' isn't bad and neither is MPH considering the previous timed increments. This could be a converter issue, setup not build. There are so many items to consider that it'd be near impossible to pinpoint any one thing off of your post. You can PM me if you're interested. You don't mention in the post but my free advice is if it's a spragless converter; there is your first major issue.

If you email me a RP log, maybe I could spot something. If that's not good, then flow meter numbers every .5 increment. PM is fine.

After talking to lots of sharp people our next step will be 125% OD, a 32.5 stator and full fuel management.
I verified CR on the engine and it has an ADRL style fuel system that pretty much needs to be aggressive to work correctly with the combo.

Thanks for all the replies,

Good luck Micah. Hope to see the 'vette running where you want.

If you need anything, just let me know.
