My Z is heating up after a high boost (15-18 psi) run for more than 6-10 seconds.The radiator is relatively new and the thermostat is new.After a run my temp gauge goes a little past the F and the Microtech reads 99 C which is close to 212 F.While cruising everything is fine. What causes the engine to overheat....advanced timing or retarded timing?
-Stock 8.3 VG30ET Turbo engine
-93 octane
-420cc injectors
-TT fuel pump
-T04e 60-1 w/Otrim turbine inside stock exhaust housing
-stock heat range spark plugs (6 heat range)
Here are my timing values by RPM and the MAP corrections.
Max timing=45
Timing at rpm: .........................MAP correction
IDLE = 11................................IDLE = 0
1000 = 29.................................25" = +7
1500 = 33.................................20" = +5
2000 = 36.................................15" = +4
2500 = 37.................................10" = +3
3000 = 38..................................5" = +3
3500 = 39..................................0 = 0
4000 = 39...............................2 psi = -1
4500 = 39...............................4 psi = -5
5000 = 39...............................6 psi = -7
5500 = 39...............................8 psi = -8
6000 = 39..............................10 psi = -11
6500 = 39..............................14 psi = -14
7000 = 37..............................16 psi = -16
8000 = 36..............................18 psi = -18
.............................................20 psi = -21
Any input would be helpful
