Renngineering - a Porsche podcast

by Renngineering - Paul Mahy-Rhodes

Season 4

Episode #68 Tech Talk | Gold Leaf performance will make your ears bleed (and you'll be happy about it)

Gold Leaf Performance I make no bones about the fact that I've been very lucky this past few years of building content, running a podcast and connecting with brands I respect, only for most of the time, that turn in to friendships. The Porsche culture seems to attract a lot of just good people. Martin and David are no exception. It just so happens they developed the most exciting modification for normally aspirated 981 or 718 Cayman's EVER. When the GT4 RS came out, despite having no need for a track biased car, I was in love. It was everything I wanted Porsche to do with the platform. It's no secret that it had been throttled back to not step on big brother's toes. So whilst developing a fully carbon (more so than the OEM version) intake that mimics the 4RS doesn't immediately turn any N/A Cayman in to one, it creates an intensely exciting package. So much so that I put my money where my mouth is, after meeting the guys at the Nurburgring, hanging out with them and spending time in their demo GT4. It's THAT good. This episode unpicks their background, the approach they took, as well as their thoughts on the future of the industry. Nerd out my friends.

Episode #67 Heritage | Ninemeister's founder Colin Belton on the 9m brand, building the 9mGT2 and giving Singer a leg up!

Ninemeister Some episodes come about over a quick brew and a realisation that we're pals in waiting. Others whether it's because of logistics, scheduling or even personal reasons, it can take months, if not years to get locked in. You know what, that's OK! The important bit is that when we get it, we get a great episode that you people all love to listen to. The other thing that's almost entirely out of my hands is whether someone is willing to share their personal journey. Some people like me ol' mate Mike Brewer, are seasoned veterans and the bit I have to do is help breathe life in to a story well told. Some people find it hard and take a while to warm up. Then there's Colin Belton who even in the first few minutes owns the space in the room and claps himself in (to sync audio tracks). :D For lots of reasons it's one of the most interesting conversations I've had on this journey through international Porsche culture that I've had. I'll take a moment out to credit Ninemeister, not Colin only but the rest of the team building the 9m cars. I looked closely as I always do and take notes on fitment of panel gaps, consistent use of fixings, fitment of rubber trim and even joins in carpet. The cars are really incredibly well put together. The team there should be proud of what they produce. Sadly for me, I didn't get the opportunity to go out in the 9mGT2 which was the point of the trip. Maybe I'll get an invite to drive the car and do a review. I suspect though, Colin is confident in the product enough to not want or need my review, and that's OK too. It's a beast of an episode though and we get through a lot! Stay tuned to hear about Colin's take on his interaction with the Singer team as they were about to go live and uncover their first ever car at the Weathertech Laguna Seca circuit. It's an anecdote to rule them all.

Episode #66 Tech Talk | Live event news and a deep dive on designing wiring from scratch with Level Motorsport Wiring

Level Motorsport Wiring Way back, when the RENN550 was being dreamt up, I started reaching out to companies that seemed a good fit. Whether it was the ethos of the company or someone that headed it up, I was carefully seeking out people that would appreciate being involved in something like a carbon bodied, Lotus chassis'd, Porsche inspired sports car. Well Matt was one of those people. From the aesthetic of his instagram page to his obvious obsession with perfection, it just made sense to reach out and build bridges. He couldn't have been nicer! That meant a trip to South Wales to sit down and learn about his backstory and remind myself of what I know, and also expose where my knowledge reaches its limit; and it does. That's OK though! That's exactly when you decide whether to extend the build time and learn to do it, or employ the services of an expert but accept it'll cost more in the long run. It is super nerdy but that's what Tech Talk is all about. The intro picks up on the RennSporter T6 Transporter van build, as well as my co-hosting the upcoming Niners Live event at Boxengasse, with Boxengasse legends, Frank Cassidy and Annabel Tatnall. People I've grown really fond of over the past few years. That event is on the 20th of September so I'll see you there. I'll also be at the Legends Drivers Club "Sonderwunsch" event at Goodwood circuit on Monday 25th! You can find Boxengasse @Boxengasseco, Legends Drivers Club @Legends_drivers_club and Level Motorsport Wiring @Levelmsw_ on Insta!

Episode #65 Heritage | KAMM Manufaktur on building the all carbon 912C and now the 912T!

KAMM Manufaktur! Sometimes episodes take months, even years to organise and shoot. Others - like this episode with KAMM founder Miklós (Miki) Kázmér, came together during a spontaneous moment where I'd finished a magazine shoot for the Renngineering Cayman S/E and knew that Miki was setting up at Boxengasse's annual Megaphonics event. With a couple of hours gap between the end of the mag shoot for 911 and Porsche World and needing to be back at Boxengasse HQ for a Michelin pre-show meal I figured I'd try to lock in an episode recording, even if it meant using mismatched audio equipment and sitting next to a group of drunk and happy tourists. What all that did though, was remove any sense of it being formal out of the equation and created a friendly atmosphere that I think we both enjoyed. You let me know whether the episode is as good as I think it is.... So everything you wanted to know about the company building carbon fibre 912's - here it is... and as I normally say at the end of each intro "I'll catch you back up,,, at the end" I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.

Episode #64 Waffle | The BIG catch up! Mag features, shows, brand collabs and new projects underway!

The BIG catch up! It's been a while... I know I know... the introduction says your weekly dose of Porsche culture and it's been anything other than weekly this year. There is a reason for all that though and this episode does a round up but also gives a proper explanation as to why that is. Despite being quiet on socials and almost as quiet on here and YouTube, it's been for a reason... Renngineering wasn't designed to just be a podcast or YouTube channel. It's always been about building the RENN550. At some point I had to sit down and figure out how to make that happen. Putting my heart and soul in to episodes was working to an extent but from a business perspective, unless you're Mat Armstrong, you're not getting paid a lot. I'm a great designer though and it's important to keep pushing on with that. So that's what I did... focused on building the business side up, that funds everything else. So here you go... the answer to all the questions and lots of exciting news! I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.

Episode #63 Heritage | Mike Brewer - HIS Porsche Origins Story

Mike Brewer! There are some people that when you meet them, you either are impressed at their authenticity and how closely the on-screen persona matches the person you meet, or you feel a bit let down that it's an act. Well that's my take anyway. Of course there's a little turning it up to 11, but the man I've gotten to know over the past couple of years is pretty much the same guy you see on TV. Now on that... in the YouTube video episode coming out Saturday 3rd April 2025, I put a two second clip in the intro of the first Porsche I remember Edd and Mike working on. An Irish green targa. I must have been in my early 20's when I first saw that episode and I've seen it a few times. Never once did I think I'd be trading messages and chatting away like old friends in person. The thing I'm doing never ceases to amaze me. So grab a megapint (thanks Johnny Depp that still cracks me up), settle in and 'old aat yer 'and! You can find Mike at @mikebrewer One Automotive is at @oneautomotiveuk and @mikebrewermotors I'll take a moment to thank you all for listening so far.

Episode #62 Waffle | Frank Cassidy is back! The ULTIMATE road trip guide

Explicit

Frank is back! It's been a while since Frank Cassidy has been on the pod. As I've said to him, our episode together is one of the ones that people mention to me most. Likewise, it's been an admission of Frank's that he enjoyed our chat more than any other "interview". Quotes because I try hard to avoid being an interviewer. Last time we caught up, Frank and I chatted about doing some episodes where it wasn't about him as a person, as we've done that, but actually our shared experiences. I suggested, based on the Niners Unplugged episode I appeared on, way back, that we do something on road trips. If you haven't watched the Niners Unplugged episode then go do that. It's pinned to my IG grid but can be found on the Boxengasse Niners Unplugged YouTube channel. In that episode, which generally goes well, Frank asks one of his standard questions "So tell me where you've been in the car..." insert pregnant pause as I scramble to remember even something basic. Not great. But I did respond by immediately planning a trip. That trip was recorded and at this point has had about 20000 views on YouTube. It didn't stop there and in the bank right now, is last year road trip. That episode will be out soon enough. We also catch up on Megaphonics and the plans both short and long-term. So here it is, Frank and I talking all things road trips. You can find Frank at @frankrcassidy and Boxengasse at @boxengasseco I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.

Episode #61 Tech Talk | Modifying Cayman 987/981/718 - Renngineering LIVE! at Porsche Club Great Britain

Renngineering LIVE! This latest episode was shot at Porsche Club Great Britain where in front a studio audience, myself and two other fairly knowledgeable owners break down our approach to our cars. We start off with Kai who owns a 2.0 base model 718 Cayman and went for a big power approach. For the 987 we've got Simon who competes in sprint events and hillclimbs so more of a focus on lightweight. I cover my car to an extent and talk about the specialness I've been trying to create with that car. We wrap up with a Q&A where the audience got the opportunity to dig a little deeper in to our insights and experiences. You can find Porsche Club Great Britain at porscheclubgb.com or @porscheclubgb on Instagram. It's very much in the spirit of old Top Gear this episode so if you get chance, head over to YouTube and watch the episode to get the full experience and see the cars we're talking about. I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.

Episode #60 Waffle | Fitting a GT4 RS intake to a 981 and going viral(ish)

What was it like to install the Gold Leaf Performance 4RS intake on a 981? I didn't have a great deal of choice last week. I wore the same scruffy garage clothes for days on end, bounced from day job to the Renngineering Cayman build, and back again. I set myself the target of collecting and fitting the beautifully designed and made GT4 RS style intake system on my car within a week. A lofty goal, particularly because I'm absolutely anal about getting things right. Close just ain't good enough. I didn't quite hit my one week goal but only by a day. Putting it simply - I couldn't be happier. I learned something in the process. All you need to do to have a successful reel is post up a short clip of a car revving to the redline. OK, I'm reasonably sure a Mitsubishi Galant 2.0 from 1994 wouldn't quite have got people excited but this certainly did. I've since put 250 miles on the car and it's perfect. Everything works just as it should. Sounds immense. Looks even better. I'm a particular fan of the spec I chose as well, Agate grey side window pods Matte carbon throughout Gold pinstripe on the engine cover In this episode I also pick up on the next few episodes being shot and some potentially game-changing news for Renngineering, that could... be the start of the shift towards it being a full time job. I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.

Episode #59 Your Porsche Stories | Bruce Floyd, Brumos and the 250'000 mile 911

Your Porsche Stories is BACK! I love these episodes. They don't happen as frequently as I would like (massive hint there) so if you have a really cool Porsche or there's a great family story behind it, or perhaps the car itself has a really great backstory - I want to hear from you. Drop me a DM or email and we'll find some time. Every now and again, I'll take the lead and when I see something cool, will reach out to the owner and invite them on. That's what happened with Bruce. I genuinely didn't know about his Brumos and Hurley Haywood connections when I messaged him, nor did I realise how nice a guy he was. All just lucky surprises. So, if you want to hear about a 250'000 mile '87 911 then grab that coffee and have a listen on any podcast streaming service. I'll take a moment to thank you all for listening so far. I appreciate all of you and always welcome your comments, questions and thoughts. Just drop me a DM or email.
