Single turbo 400
#106
Wow, those are big numbers and high boost, 24psi. Has anyone found out at what psi the heads start to lift or the block deflects and the engine pushes water? I know on LSx engines going over 20-22psi starts to get into the range where you can start lifting the heads even with LS9 head gaskets and studs over torqued.
Can't wait to see what it makes in the car. Also what transmission do you plan to put behind this beast? Edit TH400, had to go back and read.

There haven't been updates since much hasn't been done since it was dyno'd. I dropped the engine back into the car today. I should be putting everything back together for most of this week. Main thing that holding us up now is a custom flex plate that is being made. But most everything else should be downhill from here. I'll put some more effort in giving up dates since we're making real headway. Thanks for your interest in this project.

hey everyone - this is actually my car...justin and meraz have been handling the build (it's actually in souther california - not washington)
the history of my gs started off simple with just the pi torque converter and srt intake...then i picked up one of the rmm superchargers sometime back in 2004...eventually got up to 400rwhp but only 320 ft/lbs of torque...best 1/4 mile time was 13.3 @ 104
i then sold the supercharger to someone on the board (ivan - don't remember his screen name) and bought one of srt's first twin turbo kits (think it was the 2nd one that mo ever built)...meraz and justin did my engine rebuild and then when it came time to put the twin turbo kit on, we didn't like the way it fit so i sold the twin turbo kit to someone on this board (who subsequently sold it to someone else...i wonder if that kit will ever be installed on a gs) and the guys began on building a single turbo kit
so i can't wait to see the final result - anyone here who has done a gs build knows that it takes a while...please refer all technical questions to justin...i don't know as much about the technical aspects of what's under the hood but i write a mean check

just an idea as i'm sure many of us would buy this..

Very nice build this is going to be.. All seriousness Justin and the builder should develop a single turbo kit for our cars. Maybe not as in depth as yours but say 400 to 450HP while keeping mostly stock parts. Maybe do like a kit with 3 stages etc... 400 to 800HP .
