carnage pics
well finally pulled the head off my blown block.. its been sitting since last weekend of september so thats why u see the rust in the cylinders.. this is what happens in the top of 3rd gear and the internal waste gate just isnt big enuf to handle the exhaust flow.. boost creep, detonation (happened soo fast couldnt really get outta it when i heard it ping), it leaned out to 15:1 a/f.. i expected to see melted pistons, but they're fine.. my datalogging was running, but car is only tuned to 12 psi which was 12.5:1 a/f.. i dont have a boost guage (something thats gonna be on my list to get here soon) and my ECU rom is only setup for stock map sensor so it only goes up to 12 psi.. so i really dont know how far up it boosted before it blew LOL.. oh well, i think my buddy who came with me to the races took it wayyyy harder than me.. i was like ---- happens.. he was like DUUuuuude that suxxxxxxxxx... i just laughed lol..
i've built a new block and getting ready to drop it in the teg today.. dropping my boost down to 9 psi where i originally had it when i was autoX'n and had no problems what-so-ever.. drag strip really did my motor in LOL
anyway, heres the pics
#1 and #3 cylinders cracked.. 2 and 4 are fine (as far as i can see)
