How loud is your Elise? db?

[GavT]

Im wanting to book a track day for this sunday @ donnington.

I have a series 1, with an aftermarket exhaust and induction kit. Is this likely to be louder than 98db ?????

Don't wanna pay and get told that it's too loud!

(its a drive buy test if this helps?)

Thanks Gav

[kevin ritson]

If the exhaust mod is limited to the silencer (ie: you still have the cat fitted), then you will probably be OK. Do you know which exhaust and induction you are running?

[GavT]

It does have a cat, the induction is a foam one no-make on it!

Exhaust, i dont know sorry.

Is there any techniques or aftermarket cheap solutions to help me?

Thanks Gav

Ps im rarely this ignorrant with cars and mods,
but i bought it as is and previous owner didn't know!

[kevin ritson]

Buy a noise meter (although noise testing isn't an easy job!)
Ring round a few circuits, they may be able to test your car before you do the day
Or just go for it, you'll find out if you're too noisy soon enough (you should be OK though)

[GavT]

I'll do the lata, Im gonna risk it!

Please donn' don't get me to drag the wife there out of bed at 7 to send me back ! she will kill me!

Cheers Gav

If you have a std manifold and a cat, it is most unlikely you will exceed 98db. In fact, I can almost guarantee it.

Should add that I went to Goodwood with a ITG, full Janspeed exhaust inc manifold and sports cat and it was under 98.

I've got a cat and standard manifold....and it's 117db!

Kelsport didn't know what make of silencer I had but said that it was half the size of anything else they'd seen!

You were cruising around like James May though

I've never been static tested at Donington. They only seem to have drive by testing.

[Bill K 111]

Sorry Gav, just re-read your post and you know that already.
I believe it's tested on the pit straight, so if you get odd looks, you might try short shifting.

I have S1 with jan speed road sport with ITG and a cat by pass and was bang on 100db at castle coombe.so if you have a sport cat you should be fine

[RichQuy]

Tested at Castle Coombe recently, 100dB @ 4k revs (more like 3.5k )

S2 111s fitted with 4-2-1, de-cat and single exit quiksilver exhaust.

[lamb jiblets]

its pointing out if to go up from 97dB to 100dB your car has to be twice as loud . (every 3 dB is double the noise)

[subaqua]

My S1 with pipercross, janspead supersport exhaust clocked 103db with the cat removed at Oulton a few weeks back, but was only 100db at Brands at the end of September. I guess there is a fair amount of inconsistency with testing conditions and equipment. If you booked it up.. good luck and have fun!

My Stage 2 Lotus Sports Exhaust with an ITG on a S2 Exigewas giving out 103-103.5db. In cold winter air that could work out even loader

[crackthatoff]

ohh havnt thought of that, hurricaine and a clubsport on an s2 anyone?

[JezF]

As I said, if you have a cat, you'll be fine.

Can't quite imagine any Elise would produce 117db unless you had a Spitfire engine in the back.

As for Ritson, you are a cheeky chappy!

S1 with standard manifold and cat. Motobuild exhaust and K&N.
No problems getting past Bedford's 98 dB limit.

[Phil. S.]

I have a standard manifold, K&N filter and Larini exhaust (with cat) - 95 db at Brands and Hullavington (airfield).

[Phil-CH]

Mine produces over 122+dB (with cat). (0.5m / 45° angle - no load).

I may even have a YouTube video somewhere...
