Here are a few pictures of my boosted '07 SI with Precision Turbo 6262 and the AJP turbo kit. Blew up the first stock motor at 40psi (overboosted with no boost cut set). Have since put in a built K20A2 with 9:1 pistons and made 440psi at 14psi. Currently running low 12's with drag radials.
Boost cut was the one thing we overlooked in the time crunch we were in. Turbo setup was finished the night before a big race and we had no real dyno time the morning after that (prior the race on same day). This mistake and rush to race will never happen again haha. Ended up breaking a connecting rod at 40psi which lead to two ugly holes in the block.
