Comparison photos of the stock 74mm TB and Soler Engineering 82mm (86mm effective) TB.
Detail shots of the Soler Engineering TB.
The installation on the Soler Engineering parts are very straight forward. However to get it to connect to the airbox was the tricky part. Soler Engineering currently doesn't offer a solution to connect the Carrera airbox to the 82mm throttle body yet so I purchased one from Flat 6 Motorsport. https://flat6motorsports.com/product...32923308589140
There is an issue though, as the GT3 elbow from Flat 6 Motorsport is intended for Carrera that has both IPD competition plenum and GT3 82mm Throttle body. The Soler Engineering adapter spaces the throttle body further towards the rear of the car. So some modifications was required on the elbow. Even after some trimming it was still a struggle to get the elbow to fit as I found out later that the inner diameter of the elbow on the throttle body end is only 85mm to 86mm while the outer diameter of the clamping area on the throttle body is 89mm.
Once the intake are all back together I did the throttle body position reset and started the car to let it idle for around 3 mins. After the initial cold start high rev and car settled on 900 rpm idle and then adjusted back down to 700 rpm idle. I shut the car off waited for 1 min and then started it again.
I did a 30 mins drive to get gas and the difference was noticed as soon as I pulled out of my driveway. At partial throttle, the car is noticeably peppier than before to a point that I had to readjust my foot so the car will go around town about the same pace as before. This happens throughout majority of the rev range. I'm not sure how much it gained at the top end but it definitely gain some area under the curve. The response from heel toe feels smoother too. Although to be completely honest I don't know much each element contributed to the improvement as I jumped straight from a standard 74mm TB to a upgraded 82mm TB.
Disclaimer: I'm not affiliated with Soler Engineering in any way. I paid full price for the throttle body and adapter. I merely just posting my thoughts on them as I'm very pleased with the initial results.
I'm heading to Lanchester landfill this Saturday after my PP seats get installed to get the car weighed. They charge $6. Something to consider.
Let me know how that goes. I'm interested in getting the car weighed t hat way too. But I know some recycling places don't welcome people that just want to weigh their cars.

The one I got is the GT3 TB (82mm) with additional machining. It would be considered an upgrade even if you already have the GT3 TB.

I can tell you right now that it isn't a problem. I emailed the executive director and he responded by saying "just let the weighmaster know you only want to get weighed. It's a $6 charge". Folks must do this a lot and since it isn't exactly free, they shouldn't give us any hassle.
Regardless, I'll let you know anyway. I'm going to ask them if I can exit the vehicle while weighing.
So after installing the Pole Postions, I weighed the sport seats (manual fore/aft/up/down, electric tilt, heat) and it looks like I'm saving 74 total lbs. The passenger side is 57 lbs, driver side is 51 lbs. Sliders are attached. The Recaros are a claimed 17 lbs each. The only unknown in the equation is the weight of the BBI base kit. Any ideas?

My stock memory seats weigh 57lbs on the driver side and 62.4lbs on the passenger side. The Recaro seat with BBi base mounted to it weigh 33.8lbs. The base is as heavy as the seat itself.
Any update on the mag wheels? Curious to see how they turn out.
Good timing. The wheels are getting shipped out this week. Per AWC, the fronts weigh around 17lbs each and the rears weigh around 18.5lbs each. I will weigh them myself to double check once they arrive. I will be saving 35.75lbs from the wheels.
Here's a photo of the wheels from their Facebook page.
I saw those posted on their IG and had a suspicion they might be yours. They look great and the weight is even better! Can't wait to see them on your 911!

Very nice. I had AW make me a set as well. Received a few months ago. Similar design but I had them based on the current GT mg wheels. Mine are forged alu.

I can't wait either. Per the tracking info, the wheels will be delivered this Wednesday. I've already scheduled an appointment to have my current tires swapped to the new wheels this Thursday. It's gonna be good!

Yours look awesome! I went with the BBS Motorsport monoblock design.
That’s a significant loss of unsprung weight. This may have a bigger impact on performance than the rest of the weight shedding. They look sharp to boot.
