Silverback build thread - 347 S485 TH400
The car is a 98 Camaro SS that I bought over 6 years ago and have been slowly chipping away at it over the years. It started out as a cammed (MS3) LS1 and all the normal bolt ons and made 400rwhp through a T56. I was happy with that for a while and as always we just want more. I then added a small shot of nitrous and put down 550rwhp. The only problem was the little 10 bolt and sticky tires ended in carnage so I wanted the beefiest rear end that I could afford at the time so I got a Strange S60 with 3.73 gears.
I later knew I wanted more and instead of blowing up the stock 98 short block I purchased an forged iron LS1 (LM7 bored out to a 5.7) short block from Thompson, custom cam from Martin, TFS 220 as cast heads, ported Fast 102 and 102 throttle body, TSP 1 7/8 headers to true dual exhaust and put down 647rwhp and 750 ft lbs through the T56 on a 200 shot. I then thought that I was on borrowed time with the T56 and knew I wanted to push it further so I sold the trans while it still had value and swapped to a FTI level 4.5 TH400 with transbrake. I also got one of their custom spec'd converters. With that setup, full suspension with Vikings at 3910lbs with me in the car it would run consistant 10.3Xs at 132mph. The best 60' was 1.38 on ET Pros and would hang the tires even on poor track prep. (Pic is before the MWC anti-roll bar)
I was pretty happy with the setup until the pump in the trans failed and caused the engine to over rev on nitrous and hurt the engine. At this point I had to decide what I wanted to do with the car. It was starting to get hard to get nitrous and I always wanted a turbo car so I made the plunge and started my 10 month journey to today.
I sold everything on the car that I didn't need any more and started stock piling parts for the new build. This is the general parts list of the larger items:
-New Thompson 5.7 with -18cc pistons, h beam rods, stock crank, ARP everything, and LJMS Stage II cam. Will be 10.1:1 compression on E85
-Reused the milled Trick Flow 220 as cast heads from BTR
-LS6 intake manifold with stock throttle body
-Holley valve covers with LS3 coils
-Bosch 127 injectors
-Racetronix fuel system with -8 feed and -6 return
-Two in tank 450 pumps and modified the bucket to have a -8 bulkhead
-LNC-2000
-Griffin dual pass radiator (58241-XLS)
-Dual derale pusher fans
-High current alt from Powermaster
-Freshed up the TH400 from FTI
Turbo system:
-Huron Speed V3 T6 system- coated satin black
-4.5" Bell intercooler
-Borg S485 with V2 race cover from HSP and Jose at FI
-2 XSPower 50mm BOVs
-2 Precision PW46s wastegates
-Custom downpipe will be made once I receive the kit to connect to my 4' Mufflex exhaust that has a 4" cutout after the firewall.
-Leash Pulse combo box
-Co2 for Leash boost controller
Suspension:
-MWC kmember
-MWC lower control arms
-MWC tunnel mount torque arm
-MWC drag bar
-BMR control arms
-BMR panhard bar
-DA Viking coilover and shocks
I have everything pretty much wrapped up to what I can complete before I get the turbo system and then I will be thrashing in the garage to get it running.
I don't have any real set goals at this time but I would love to see the car in the 8s and will be doing Drag Week 2018 in this car so I have to catch all my safety requirements up before then.
I apologize for the pic dump but I figure most will want to see the build and catch up to today.
