Track Day Noise

[Nick Cooper]

Just booked to go on TVR track day at oulton park it says its a noisy day at 105db but a bit concerned i may be to loud, its a 4.2 with sports pipes but not de-cated, any one got one similar whose had there noise mesured?

Mines exactly the same - 104.6db. For 100db days I use the track day silencers from act and they drop it to 99db

When they ask you to rev it to whatever rev limit (4k) rev a bit under if you can.

All Cerb's rev to 5500, well that's what ALL scrutineers are told!

NEVER admit what a Cerb' revs to, and you'll be fine.

Thanks for that guys, think i should be ok as mine only revs to 3500rpm!!honest

Just be careful the last track day I went to, there were 2 guys 1 holding the db meter by the exhust and 1 looking through the drivers window at the rev counter.

My 4.2 with sports pipes used to hit 108db @ 4,000 revs. Drop it to 3,500 and you should be fine

Run it up slowly - don't overrev as they take a peak reading. It's quite hard as it's a fine adjust on the throttle.
...and take it down slowly. Don't let it backfire.

Yeah, that big lazy V8 only revs to just about 6 in our car...



Once got done for being too noisy after saying it revs to 7krpm whilst a decatted sports exhaust S6 Cerb was allowed straight through as it only revved to 5500! We learnt a lesson that day...

What time and how much is Oulton park on the 29th? I'll be back from my trip to europe and the car will be in Manchester and not back in Scotland.
