Soo here we go again. 3rd time lucky? Maybe..
Got an oval silencer. It’s 7” wide and 24” long.
Also inserted another 2 half moon baffles in to the pipe. Hopefully this will work!
After a test, at idle Db dropped by 5db.
At 5000-5500 it hovers around 103-105 But strangely jumps to 109 as...
It will be fine :) for a man of his talents haha can rewire 3 of them by that time haha especially using cartek pdp. More than happy to help. Not that he needs any!
Out of curiosity Rob, why Heater and not heated windscreen?

Nope none at all. Anything forward strut tops and engine/box mounts is there purely to hold things in place like wings, lights etc etc. Obviously might not be the best idea to remove all if it’s a daily. But for a track car with a full cage no issues.

All done ready to test! Sounds awesome. Nice and deep sound on idle. No drone! Inside the car only a tiny bit louder. BUT! According to my Db meter it’s still way too loud! This was out in the open. 5500 rpm. 59cm away at 45deg angle. Maybe my meter is phucked. Or it’s just too loud. Sod it...
Haha! Really do t mind lol.
This morning woke up thinking it’s still too loud. So decided to add 1 half moon baffle just before secondary silencer.
Will see. If not enough can always add more. And based on my research this design, angled at 45 deg covering about 40% of the diameter has minimal...
I heard that as well. Let’s hope not. There are a few things I can do further to reduce Db. But think it’s fine for now

Quick update. Welded a second silencer in place. It’s 3.5” diameter with 2.5” inlet/outlet. 450mm long.
A quick test is showing its way under 105bd static most circuits use. But only at about 4000rpm as didn’t wait for it to warm up. Pointed the exhaust to the open side of the garage this time...
Yes Dogbox :) made in Holland. Sequential a lot more money. And less tourque. This will handle 600+ nm
Will be beautiful. +cant use sequential in any of the championships. Not that I think I will ever use this car for any. My sole and daughters college invested in this. If I even scratch the...
Oh thanks for that! Yeah car is like 40cm from a wall lol. So sound defo got amplified. Maybe I need to drop it and roll out in to the open. Hmm
Like the baffles! Watched YouTube vid last night guy made few different ones cones, spiral etc. So I knew I could use similar techniques if all fails...
