Noise Meter

[blobbish]

The ZED is now supercharged and booked in for coilovers, sway bars and a Diff.

 

I plan to do a few track days soon and although I have decats with a silencer the zorst is still quite loud. So does anyone have access to a noise meter so I can get an accurate reading.

 

I know you can get phone apps but there just not accurate.

BookaTrack used to hire them for £10 inc p&p, give Jonny or Sarah a ring on 0843 208 4635 and I'm sure they'll be able to help.

You can buy a sound meter from ebay/amazon.

It'll give you a fairly reasonable approximation.

Will be only good for a guide, i have read different db's at different tracks with the same set up. Think you may struggle with decats.

and a blower

[brillomaster]

where as you based? most trackdays I know will be happy to test a car for you, just a case of popping along to your local track when there is a trackday on.

Tbh if you're thinking of tracking your car you should aim to make it as quiet as possible. Put the cats and stock back box on for the day, trackdays aren't about the very last horsepower and we as enthusiasts should make sure we don't give the NIMBYs any more ammo.

[Kev T]

Not sure if the standard cats will cope with the extra pressure from the blower, particularly on a high revving track day.

I have hfcs on a true dual on a Vortech V3, very quiet exhaust and passed at Thruxton the most stringent in the country, 90db static.

 

As Ekona says, for the few extra hp the decats give you its just not worth the hassle and you probably wont even notice the hp lost.

Smartphone App available for both IOS and Android, does a decent job and to be honest was not that far off compared to one we borrow of H&SE

[blobbish]

I will try the android app initially and see what it says. I removed the HFC as they just get burnt out and fitted Decats with silences to reduce the noise.

 

Abingdon airfield have quite a few track days so I may just pop over.

I bought a noise meter from maplins a few years ago. It's been fairly accurate and reads pretty much the same as the ones MSA scrutineers use at any races we've been to.

I don't remember it being too expensive.

If you're anywhere near North Yorkshire, you're welcome to borrow it.

I bought one of those £15 ones from Maplins today , on idle 1 m from the tailpipe my car was 110db Yep bit fruity
