Hi Guys, I am hoping to get a day in my scoob my93wrx at Goodwood soon and want to know if my car should pass the 98dba test there. I know there was some scooby guys there in Nov. from earlier post, I have to know before I book up. I have normal down pipe and mid section with slightly bigger backbox(jap Kackymoto)
cheers,

Jamie

 

Hi, I've got a UK scooby, with factory system with Blitz back box, and passed at 96db at 5200rpm, tested at Goodwood last year. (Didn't do the track day, was watching and wanted to see if I would pass! )
May give you an idea or comparison!..?

 

Cheers Stuart,

That's a great help.

Why not pop down there and find out for sure? The marshalls are friendly enough and won't mind. Personally, I think that you'll probably be OK with that setup.

I went down the day before my track day to have my car tested and the marshalls said confidently "Impreza! No problem, they never have any diificulty passing". I promptly posted a reading of 107dB despite being in silent mode and being 300 revs short of the requested level. Happily, I was able to "fabricate" a temporary silencer in time for the next day.
