Hi all not sure if this is the right place for this but here goes, im thinking of booking a trackday at donnington park in a few weeks when i get my zed just dont know if it will pass 98db noise limts as it has an exhaust and filter any ideas if any of you have the same sort of thing and have passed the tests they do? Its a twin turbo just in case it makes diffrence.

 

Any help would be appriciated?

 

Thanks

Castle combe has a 100db limit and from what I have seen nearly all modified examples (Z32, Supra, Rx7, Evo...etc) were passing the limits. There are bolt on silencer options (they fit in the end of tailpipes) for those that dont meet the limits.

 

If its louder than most other 300zx's with aftermarket exhausts then you may have an issue and have to use a bolt on silencer.

where would i get a bolt on silencer from so if i didnt pass it i could quiten it down so it will pass? ive never done a trackday but would really like to.

I've only seen them at the Track day events, being sold/hired by Traders on the day. Must be able to get them elsewhere though.

hey there turbokid

 

i took my 300 to snetterton last year for a track day and had a noise limit test!!!!!!

 

i got hks induction, no cats, with only 2 silencers on the back (2fast2cool cat back exhaust)

with rev limit of 7400.

 

had to hold the revs at 5500 and was very LOUD!!!!, but passed with flying colours.

 

 

no probs here!!

 

al

cool i think the best thing is to get it tested before i go or go to the silverstone one which is 105db should pass that one lol.

Have to wait till next week see how loud it is then decide i guess?

 

thanks for the info people all help apprciated.

Well lol... I did a trackday in my red car at the Bedford Autodrome. Noise limit was 105Db and I was over it :( They put a red sticker on my winidscreen and monitered me throughout the day.

 

Crazy thing was the exhaust was not all that noisy!!!

 

The Kakimoto on the black car is FAR more noisy!

 

 

 

So beware :)
