Noise levels for a Superlight R

[samurikid]

Want to get it on to a track BUT - what sort of noise levels do people think a standard system (with Kat) will do ? Remember some tracks are looking at 98 Db thingys , so does anyone have any experience of this ?

This is being discussed on Blatchat.com at the moment in Tech Talk.

But you will struggle on Donnington or Goodwood. My R300 engine on rollers and a 7" Race can has been ok everywhere else. Its more induction noise with my car - No air box, just foam filter

I have a SLR and didnt have any problems at Donnington. Have just used the Booka track noise meter and got 95db at idle - 102db at 6K and 106db at 7K.

Hope that helps!

Dony's limit is 100db IIRC - 98 sometimes....106 db won't get you on any circuit I'd have thought....I'd say you were lucky...

My R300 was 95 at 3/4 full revs, at Combe a couple of weeks ago. I couldn't get on Donny

Mmmm - thats a touch close - looking at doing an evening at bedford , they state - 101 Dba at 3/4 revs (so thats about 5600?) and 87.5 (! ) measured 20M away at full poke ...........no where did I put plan B ?

[rjnewman]

Sorry - those figures were taken at .5meter away from the car. They're not drive past! Also with Donnington I think the wind directuion helps and not gunning out of the last corner as well

what do i need to buy to find out the db level from my car? what and from where?

db meter. Just google it and you`ll get loads.

I borrowed a noise meter from bookatrack - cost £9 including postage. Give them a go.

Also went to Sneterton last night and declared the red line at 7K revs so had to do a static noise test at 4500 revs. Reading was 92Dba. I do have my cat fitted as well.
