Still in mock-up and already want to upgrade Hey guys, I'm putting together a '84 chevy truck with a 6.0 engine and a BW S475 turbo. It's a race only build. I have a '05 lq4 engine, going with forged rods and pistons, 317 heads, edelbrock intake and blow through carb. I have a 4k stall convertor in front of a th400. It has a ford 9" with 4.30 gears ( for now) and 32 inch tall slicks. It weighs 3400# with me in it. The problem is, that I have a new S475 turbo, but found a Turbonetics 101mm thumper with ceramic bearings for less than a grand. It only has 30 1/8 mile passes on it. I don't have the a/r on it yet, and it has a small turbine housing. They went with a precision 106mm. Problem is, I'm not sure if it's going to be over kill or not. I'm not looking to break any records with this thing, just a week end warrior type of toy. I'd eventually like to run the 5.80 index in the 1/8 mile with it.
So what do you guys think? Will the thumper be too big? I'm thinking with the small turbine housing, 4k stall, two step and trans brake, I could possibly get it to spool. Any and all opinions are appreciated. Thanks.
