If its a time attack I doubt that its a big turbo, like smaller than 30R? for faster on/off boost performance. Where I can see wanting to have the most efficient wg setup you can. Honestly though, how many of us actually see boost fluctuation issues with single wg’s anyway? I know my lil 38mm 3076 hit my set boost and stuck there like glue, never over boosted, crept or anything.
The head on the WG and the body takes alot of room up really. it doesnt sound like a lot on paper, but stuffing it in the mix between coolant hoses, wires, belts, what not can be tricky, then plumbing it still… I can see space being an issue unless its gutted out under the hood.
who knows.
