TLDR: Car bogs and stalls on double-apex right after full-throttle straight.
Detail: MSR Houston road course, CW, going into 5-4-3 Diamonds Edge after full-throttle straight in 4th at about 110mph. Downshift and brake, double apex right at about 45mph, left kink at full throttle, car bogs just entering the next straight. First time it happened (first session, first hot lap), complete stall, turned over 4-5 times then restarted and I drove into the pits. Second session, first hot lap, exact same scenario, downshifted to second, no change, let off full throttle, car responded, limped in at partial throttle, day over.
Saturday, no issues at all, four great sessions, Firehawk Indy 500s, started with Exxon gas, filled at lunch with Shell.
Sunday (day of problem), had swapped to RE71s and just filled up that morning from a different Exxon station. After calling it a day, I drove home over an hour at highway speeds / partial throttle with no issues.
01 GT, stock tank, "supercar" pump (255 lph I think), new fuel filter in January. Tons of track days on this set up, never had a starvation issue with a full tank before, never had a problem at this track with RE71s.
Thanks for any guidance.
