Here in CA, they don’t bother nice cars with exhaust only rice rockets.
as far as smogs go, I can help members who need a “friend” 👍🤭.
Hello there friend LOL, maybe down the line when I do go with 200 cell cat's/headers while I still reside in Cali.
But in all seriousness, this does have me seriously considering this maybe next year, would love to wait and see for more longevity and reliability tests... OEM 991.1 replacement engines ain't cheap.
Very nice-I am surprised you didn't pick up any power moving from catted stock headers to these catless units...any reasons you can think of as to why?
Yeah I should clarify, there is probably a 10hp gain vs stock manifolds, but we removed the cats on our stock manifolds when we started tracking the car, as I didn't have too much confidence the stock cats would hold up to that kind of abuse/heat.

It may be possible to install on a PDCC car and still retain the PDCC pump, we just need to find a PDCC car in order to take a look.

Awesome...I think if you can have a tune to set readiness on the OBDII system you could sell a few of these in CA.

Thanks for your earlier response to my question about drivetrain reliability. That's an interesting comment about removing the stock cats before tracking the car. I have Soul sport manifolds, with 200 cell cats, I believe. Would they withstand heavy track use if I added your supercharger kit?

High quality 200 cell cats should hold up well due to the reduced backpressure/temperature, and the fact that Soul's catalyst substrate core is brazed to the pipe. Additionally, I just got off the phone with Soul, and they assured me they would honor their catalyst warranty for SC customers.
We had a local C4S install lined up for this week, but unfortunately was cancelled last minute, so.... we are extending the initial install deal to a new customer. Please private message me to discuss pricing, all I can say here is the discount is well worth it!
Also, wanted to thank Rennlist member, TheChemist, for visiting us today. I was happy to give him the experience of a nice 150+mph acceleration run in Mexico Offer stands to anyone who is able to make it out to Philly, we are very transparent about everything we do, and I encourage everyone to experience the 911RR for yourself before making the commitment to take your 991 to a whole other level!
Lastly, big thanks to everyone on this forum for your support and positive feedback since we went public with this kit a week ago, its a welcome change for some of the lack of civility you see on other forums/groups.

Thanks very much for meeting with me and demonstrating the incredible performance of the 911RR! For anyone wondering, Rafi definitely knows his stuff and has put together a high quality and high performance package. I'll followup soon, we just need to confirm that the PDCC reservoir won't be an issue.
This looks super promising. I do have a PDCC car, so doesn't even look like an option for me. Probably a good thing LOL
Well, you are both in luck and out of luck. Yesterday TheChemist stopped by the shop and we had a detailed look at the PDCC... I can say with very high certainty that we can accommodate the PDCC. We have a non-PDCC in the shop next week for SC install, but we expect to have the PDCC car in within about 2 weeks. PDCC requires a relatively minor modulation of the SC support structure, not a huge deal.
We are proud to announce the completion of another Porsche 991.1 C4S Supercharger kit install! This car was our first C4S and required some redesign of our water tank & water line routing to accommodate the AWD specific fitment. Big thanks to Bill from TN who shipped us his beautiful 15 C4S to our facility in Exton, PA.
This package put down a very stout 480whp/413ft-lbs (93 oct & methanol) on our dyno, providing a substantial increase (+130whp) over stock.

Was that 480 all wheel hp? If so, that’s quite a bit!! Is that considered stage1 or 2 with meth? What psi pulley are you running?
Our “official” output is 460-480whp, and yes that’s all stage 1, which comes standard with water/meth injection failsafe system. Workin on “ Stage 2!” Which requires some fuel system upgrades.
peak PSI, at redline is about 7-8psi depending on outside temp.
