Built Evo 8 back on the dyno this afternoon after we did a full inspection and dyno at 630ish AWHP last week...
Fixed up a bunch of issues on the car and got it back to a swift 700+AWHP π―
Transfer case leak fixed: added missing o rings and resealed correctly, added missed transmission to t case dowel.
Fixed 4 leaks at the timing cover: crank seal, oil pump seal, castle plug o ring, and patch up a crack in the front case
Resealed leaking oil pan, and re did leaking turbo oil drain.
Found 3 destroyed GSC valve stem seals in the oil pan, which address the smoking issue on startup the car was having. We will be pulling the head off in the future to rebuild correctly.
Retimed the engine correctly to only 1/2 tooth off for a 2.1 long rod 4g64 block with 4g63 head. Timing was off 1.5 tooth at the crank
New spark plugs and bumped up the m**hanol nozzle to twice the size.
Fixed up a boost leak at turbo with new coupler and clamps.
Fixed up transmission pan oil leak, and fesh fluids everywhere.
Back on the dyno and made an easy 723 AWHP at 39psi pump gas/m**h and 475 AWHP on the alternate conservative map with no m**h.
