SMSP has a 95dB limit for track days, however it appears they don't really enforce it, especially when they use the main straight for Roll Racing and those cars are anything but quiet.

Also screamer pipes are such a distraction on track days, you're too busy enjoying the noise to actually be focusing on driving fast lol.

Depends where the microphone is for the noise meter and I don’t think drag racing has the noise restrictions 

Apparently it's at the control tower, yeah I know Roll Racing doesn't have it however the irony is they use the same main straight.

My understanding, is SMSP doesn't have an actual noise limit from the Gumbyment. Other tracks do. Hence they opt in / out of who gets noise restrictions on which days.

That is my understanding from like 15 years ago when I was there.

That's so dumb.

It's the age of case of "Even though we can, maybe we shouldn't do it all the time" so they don't annoy everyone

While there's "not a lot" close to EC, that sound does travel.

 

Roll Racing may align with Top Fuel on some nights, so Top Fuel will be way louder, may as well let it be loud at RR.

When WTAC gets in, it's a HUGE event, better open it up a little (Being on the start finish line, it's nicer if cars keep below the 95dba limit).

 

95DBA is pretty darn loud. Especially since it's measured at race tracks at 30m from the edge of the track normally!

So think about how loud a car is when it gets book at over 90dba on the road at 1.5m, and then imagine how much louder it is to get to 95DBA at over 15times the distance...

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
