Replace the seal, and torque to spec. Overtorquing it damage the seal, which is then band-aided by overtorquing it even more, etc etc

That "occasional track day" is why I would recommend also getting the Jackson Racing oil cooler with your supercharger kit.

You won't need a pressure/temp gauge; the system is already proven. If you want one anyways, I would recommend using an OBD2 type device, or getting a P3 vent gauge for stealthyness.

Should I have @CounterSpace Garage schedule you in for an install? CSG is only about 90 minutes away from Oxnard.

As for the gauges a lot of people coming in have been getting ortiz custom pods as of lately which is an entire new bezel piece that integrates the gauges into the bezel and looks fairly decent, we have also done a few gauge installs in the glove compartment which are nicely tucked away until you need your readouts.

Do you have a build thread or blog of your 600 whp brz?

I need these seal for my JR engine oil kit I bought from you. Do you have them?

Thanks for the offer, I already have the install covered.

I'm sure owners here are familiar with the fluttering sound the SC makes when off throttle at high rpm which sounds a lot like compressor surge. At my local tracks the car sits at this high rpm through long bends frequently and was wondering whether the long term reliability is compromised by the compressor surge, would switching to a proper blow off valve be a possible solution or should I just stick with what I have?

Make sure your bypass is properly plumbed to vacuum.

It is, my mechanic even zip tied the vacuum lines just in case. There are three of us with the same kit in a group chat and they all sound the same so I'm assuming they all do it unless we got a bad batch of by pass valves. But below 6k rpm they make the whooshing air sound. Just at the high rpm does it make the compressor surge sound

Not familiar with this. Do you have a recording?

Since you said there is no leak, the sound could be just the bypass valve. If you are suddenly releasing the throttle while accelerating hard above 5000rpm, the bypass valve recirculates the extra air until engine rpm is reduced. Fluttering sound you mention might be that sound. If you have to suddenly abort a strong acceleration, manually up shifting decreases the pressure by reducing rpm so that bypass valve wouldn't handle all that extra pressure and make the fluttering sound.

Can you get me a video clip?

It should be a singlar "woosh".

The way the kit is designed, compressor surge is virtually impossible. There's a reason why the bypass is directly after the supercharger.

[Canehda]

Working on the video clip, it's a. It obscure with internal go pro mic so I'm trying to grab an external mic so you guys get a more accurate sound!

[adjusts]

anyone else getting weird thump sounds under abrupt throttle? Inlet tube seems to be compressing.

For those of you running a C38 with the high boost pulley on e85, can you comment on how it feels? I keep seeing comments on this forum and elsewhere that this kit is "underwhelming" in pull, but I find it hard to believe a 2800lb car with 370whp is underwhelming in feel or performance. I'm guessing most of those comments are directed towards a fairly stock car with 91 octane.

Can anyone here comment on overall feel at that boost and power level?
