Default Problème de son à Tremblant ?

Pour ceux qui était à Tremblant lundi et mardi, vous avez peut-être vu mon "extra" silencieux sur mon GT4 (981).
Alors que l'an dernier je faisais une collection de drapeau noir, même en maintenant le rpm en bas de 5000 tours (à moins de brocher les valves, ce que je n'aime pas), lundi la piste m'a mesuré à 84 db. Il n'y a pas de modification à faire au véhicule et ça s'installe en 2 minutes. Je ne suis pas capable de dire si j'ai eu une perte de puissance, donc s'il y en a une c'est minime.

Cette solution fonctionne pour les GT4 (981) et les GT3, GT3RS récentes. Le fabricant en Allemagne les fabriquent en petite série sur commande. Si ça vous intéresse vous pouvez m'envoyer un message en privé, je pourrais lui en faire fabriquer une série.

Martin.

J'ai acheté les embouts de virage silencieux JCR et je vais les tester.




Si j'ai besoin de plus de silence, je vous contacterai.

When do you think you would be able to report back with your findings? I am in the market for a "silencing" solution.

I finally got on track a had a static noise test but no drive by data. 991.2 GT3 tested at 4k revs was 92.1db, which I thought was very low. My old 718 GT4 stock was 94db static at 5k revs. I won't have another noise test until July. I'll fit the OEM tips on next week and see what they test at.

At Goodwood this past week where it was tested 4k revs static at 91dB. Non-JCR equipped GT3 tested at 95dB.

I tested drive-by of GT3s w/o JCR and at max at full chat past the pits their highest was 103dB so perhaps 98dB or less if fitted with the JCR kit.

Thank-you for reporting back!
I have yet to fully test my Nurburgring Tips from Dundon to meet 92db with a 991.2 RS
