[ZR1] ZR1 ultimate Track build getting closer to finished
C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
Temperature mitigation modifications are working great thus far - only managed one 15 minute session before oil burping due to too high of sump tank level and high G forces shutdown the day.
after 15 minutes of what would call 85% pushing it - engine coolant peaked at 205 F, oil peaked at 210 F and AIT2 never got above 100 F.
AIT2 has creeped up to 109-110 F in stop and go traffic on a 88-90 degree day here but drops quickly back to under 100 F once moving again.
water injection amount is very low currently and plenty of room to increase amount being injected if needed.
COTA coming in few weeks for a real test - all the issues had have been addressed (oil burp and loose spherical bushing in front control arm).
managed 1.4 G’s on stock run flat Cup tires - can only imagine what sticky Hoosiers are going to hold - have heard of guys holding 2.5 G’s with them....
Side note, I would be interested in seeing a list of your stock components that you're looking to sell. My car came to me already modded, and most of the stock pieces were misplaced by previous owners. I would need the stock air intake and engine cover at the very least. Granted, I may never put it back to stock, but I would like to retain that option.
Looking good!

Sold a lot of parts that I replaced - but have stock air cleaner and engine cover still. Hood drip piece around windshield bottom as well and some other misc. items.
Stock alternator, stock radiator and stock starter as well.

Your car already is probably already a sub-20 car as it sits.
Do you wanna share your AIM data?
fwiw if you want to run in Nat's you'll have to run TT in two weeks at Hallett AND TMS to get the sufficient number of competition days required for nationals.
Another couple cooling mods - a Setrab series 6 34 row on return from pan to sump tank with -16AN fittings/hose in driver side pumper pod and a Setrab series 6 25 row on passenger side for oil - both stock coolers still in use as well.
results - 220 coolant, 235 oil, 240ish trans temp and IAT2 still holding at 110 at end of 30 minute COTA session. Hitting 2:27 laps pretty easy in traffic - driver slowly getting better.
