new turbo, new heads/cam, new fuel system and MOAR BOOST!
Some of you may have seen my previous build thread, https://ls1tech.com/forums/forced-in...-t56-gt45.html, My old ebay gt45 turbo died when some debris clogged the oil restricter and killed the bearings. So i am gonna try to make some real power out of my baby ls1, the 5.3
Old setup made 452/503 on 6 psi with a bone stock 5.3 with a fast 92/92 setup, tomorrow i am gonna hit up the dyno and pray for some exciting results and hopefully dont blow anything up!
~New mods since previous dyno~
-Tc78 turbo, .96 a/r with custom 3.5" vband on the exhaust side (standard is 3")
-Deatschwerks 80lb injectors
-Deatschwerks 355lph fuel pump
-Custom ground cam 224/232 .590/.590 @ 114
-Ported 317's milled down to 63cc should put the cr at 9.7ish
-Patriot gold Double valve springs
-ls7 lifters
-hardened pushrods
-Manual boost controller
Any one wanna guess just for giggles what they predict?

strange enough i had no compression on cylinder 7 for who knows how long and i never even knew it, car still drives fine and pulls hard, but it was sketchy on the dyno so never got to make a full pull before we did a compression test
