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 c...

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

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 sugges...

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...

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. ...

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...

Episode #58 Heritage | Richard Tuthill - HIS Porsche Origins Story

Finally... FINALLY... The Tuthill Episode! We're back with a new season, and I wanted to kick this one off with a big bang. What's a bigger bang than a rally driving legend that is just crazy enough to build an 11000rpm aircooled 911, run an ice driving event and has time left over to build a modern take on the Porsche GT1, the Tuthill GT ONE. More than that though, the company itself carry out restoration builds, the SC RS, the 2.0 cup, and are again, just about mad enough to say yes to (almost...

Episode #57 Waffle | What on earth is going on at Porsche?! Mick joins for a classic, certified, waffle

Mick jumps back on the good ship Renngineering. It's always fun us two getting together to rattle through what's going on in our lives but when Porsche release a do not drive statement just in time for a Waffle, it was always going to be good. We also gave our thoughts on the GT3 992.2 and the 911 Carrera T. A cabrio... really?! I hope you're all doing well. If you are get out and drive and if you can't do that, get planning a trip for when you can. Thanks for listening. I'll take a moment to th...

Episode #56 Heritage | What to do when you don't want to build a Singer 911 but that's kind of what you're starting with!??

Picture this... you've found a car that sounds like a scam, but it's a Singer style shell, sat at Tuthill Porsche. It's reasonable money but you're taking it on, basically on trust. You then don't want to build a Singer tribute and go about building something yourself. That's what Paul Leyton did with this 911! Some people have a natural way about them, that makes you feel that nothing is worth getting too upset about, and that it'll all work out. Well this episode gives you about ten of those e...

Episode #55 Tech Talk | Wrightune! Aircooled engines and choosing an engine for the RENN550

A big personality from a big man! Some episodes you listen back to and find yourself smiling a big dumb smile. That's what this episode did. Partly because it was so useful for me to learn about air-cooled Porsche engines, or at least start that journey but also because he's such a good laugh to be around. You'll hear us talk about Chris and his dad's background in racing, including a Jacky Ickx Le Mans winning engine build, Chris's own motorsport career but also how he's part mechanically minde...

Episode #54 Waffle | The Comeback Kid!

The comeback kid What a strange couple of weeks! With an episode that was difficult to record, difficult to edit, and difficult to put out, you couldn't make up the u-turn that came after. With that pause and reflection in the bank, and the need to buy a new daily runabout, particularly for the winter, it was looking more and more like buying a VX220 or Elise donor car for the RENN550 was going to be a 2025 thing. The budget for a donor isn't huge, with the early phase of the build but self fund...

Episode #53 Waffle | The honest episode.

The honest episode. I remember listening to Porsche Cooled with Michael Bath just before Renngineering started and hearing him talk about being tired and it being a pretty labour intensive thing to do, putting out a podcast weekly. Blindly positive, I thought how hard can it be!? Turns out there are two answers to that. If you have a team around you making it all happen and you can be the host, pretty sensible. However, if you're a pretty normal working guy or gal, and having to do it all, well ...

Episode #52 Waffle | Mick IS a co-host, Porsche coming down hard on companies and what 100k Porsche?

This week is a break in the big episodes and I grab Mick for some good old fashioned Waffle. With absolutely no planned conversation, we surprised ourselves and found that there was quite a bit to talk through. We start by trying to figure out what Porsche is trying to achieve by forcing brands that are woven in to the brand to no longer market their cars as a Porsche, even when they're built off one. We chat about Mick seeing the new 992.2 just last weekend and his first thoughts. That led us n...

Episode #51 Tech Talk | The GOAT of Porsche interior trimmers - Dave The Trimmer

I agonised over who to use for interior trimming. With any company I choose to use for my Outlaw Cayman, the hope is that I'll have a great experience so that when it comes to building the RENN550, I've got the relationships and trust in place to know the product at the end is what I'm looking for. I'm frustratingly difficult as a customer. I have such high expectations of people that it's rare that I'm completely satisfied. That's not to say everyone is awful. Far from it. But, companies are tr...

Episode #50 Heritage | Hospital stays, racing in the 24 Hours of Daytona and owning a Porsche Carrera GT!?

Flipping heck. Sometimes you get to speak to someone and wonder what living their life must have been like. Chatting to Graeme and his wife Kerry, at Porsche in the Park 2024, allowed me (and you) to get an insight in to that. At least a little bit... From crashing his first car and putting himself firmly in hospital after passing his driving test 20 days prior, to racing at Daytona, to the Porsche Championship and winning races (draws breath), to collecting and owning a Porsche Carrera GT, Grae...

Episode #49 Tech Talk | Founder of Hartech Porsche Barry Hart on his career and why you shouldn't panic when buying a 996/997

Barry Hart. A name you may have heard but possibly not. Hartech... if you've owned a Porsche, or even thinking about an early model water-cooled P-car, it's highly likely you've heard the name. If you've listened for a while, you'll know that Renngineering isn't only about the tech side of Porsche ownership. It's about the people and culture that goes behind it. When you've been working on these cars as long as Barry Hart (78 years young), there isn't a lot you haven't seen before and don't know...

Episode #48 Waffle | Mick and I catch up on Tuthill, PADM failures and the future of British Porsche clubs!

We're back! Season 3 couldn't kick off without some good, old fashioned Waffle. We kick off with a general catch up and talk through the car park, given we've gatecrashed at Porsche Portsmouth, whilst Mick drops his car in for its THIRD PADM module since birth. After moaning about the one British part on the car, we get in to the chance to get back on the road, and how great our experiences are with Michelin tyres! With Michelin having recently collaborated with Renngineering, it has given us ti...

Episode #47 Waffle | Mick and I talk all things 992.2 and I relax about not ruining my car (finally)

Well after a short recess, Mick and I are back to talk about all things 992.2. But, before we do it wouldn't be a Waffle (trademark never going to be applied for) without a catch up. With Mick recovering from some kind of lurgy, I take a little pressure of him and chat through how I feel about the interior work on the Outlaw Cayman now I've had it back a week. This episode wraps up season 2 of the podcast and I'll be taking a short break for a holiday, before getting back to it and starting to p...

Episode #46 Waffle | Mick returns and forgets why he's there. We debate wild interiors and chew the fact over the future of F1

He's back. You didn't ask for him and you got him anyway! Mick returns to the podcast to prop me up and review everything that's going on in the world of Porsche. We had intended on talking about the 992.2 launch, but in true Waffle (R) style, we failed miserably and ended up bantering with each other. We did, however, work through Kalmar Porsche and the option to take ANY P-car and make it a safari. We deep dived in to F1 post 2026 and fantasised over increased noise, compressed engine builds a...

Episode #45 Heritage | Duck & Whale Magazine founder - Lee Dean, and his journey to a fully immersed Porsche life

This week I'm joined by Duck & Whale Magazine, founder, editor and Porsche brand low key icon - Lee Dean. Lee is a bit of an enigma. You can tell from watching the content on YouTube, that he's a deep thinker and the passion for cars, but particularly the Porsche brand, runs through him. I had been wanting to chat to him for some time. In fact, his own 911 had been a source of inspiration for my own Porsche Cayman, particularly running the Group 4 wheels. Thankfully we both managed to carve ...

Episode #44 Waffle | Legends Drivers Club @ Goodwood walk around, Dave the Trimmer and shooting with Wrightune

This week covers a jam packed U,K. bank holiday weekend. The bulk of the episode looks at a review of the Legends Drivers Club event at the iconic Goodwood circuit. Considering how poor the weather was, some absolutely amazing cars came out, both classic and modern. That sums up the LDC events... inclusive. Inclusive in terms of people, and in terms of P-Cars. Also I cover plans for my Outlaw Cayman, and give a run down of the immediate plans, which included dropping the car to Dave the Trimmer ...

Episode #43 Waffle | FULL road trip review | Belgium / Nurburgring / Porsche Museum / Reims / Rouen F1 Circuit

What a fun thing to do... To sit down and replay a road trip. Reflect on the high's and low's (there were both). To talk about what I learned from the Monaco/Route Napoleon/Col de Turini/Col de la Bonette and apply some of that to this year. You'll have to listen to find out if I managed to do it "better". A big big shoutout to Nathan, to Joe and B-roll Roger, and to the guys, David and Martin from Goldleaf Performance. Last year and doing it completely solo was fun but it was a really fantastic...

Episode #42 Waffle | Live from the European road trip!

It's hard shooting a road trip, being in the moment and then getting a podcast episode recorded, edited and out. So it's a couple of days later than planned but it's here! After five days on the road, I sat down with a good mate of mine and we talked about the trip so far, his Porsche experience and being mates for 25 years. It's been a fascinating road trip, and I give a sneaky peak in to one of the odd things that happened just that day. I'm definitely flagging though and ten points if you not...

Episode #41 Waffle | When modifying goes wrong! a Pre-Nurburgring trip special!

This week's episode comes a day late! The unintended consequence of locking your Mac, mic, storage devices etc in the trunk/boot of your car and then BRICK the car!! Just days before the start of a massive road trip. I believe the phrase is "sub-optimal". So this episode picks up that story and talks about the prep ahead of that trip. I'll be documenting the whole trip as you can imagine but it makes sense to walk you through what the trip has shaped up to be. A mix of Band of Brothers tour and ...

I personally enjoy shooting Tech Talk episodes the most! They're all special but as an engineer, the opportunity to be inquisitive, ask seemingly dumb questions and have an expert teach me (and you) about what it takes to be an expert, and get a proper behind the scenes... It's a real privilege to do that. This weeks Tech Talk follows on from the previous Renngineering episode where I unveiled the RENN550 in much greater detail. You can see that on YouTube right now! It's about partnerships thou...

Episode #39 | FULLY introducing the Renngineering RENN550 project

Last week the trailer for the RENN550 was made public. Today, I break down the design details and share some of the partners involved in creating what will be one of the few truly remarkable sports cars. It's a big statement, but in a world of huge horsepower, huge tyres and excess, the RENN550 stands alone. Lightweight, appropriate power and torque, low to medium grip. The car will be designed to feel urgent but move around on the throttle. To feel like a Porsche 550 Spyder but on steroids. The...

After what feels like years, Caffeine and Machine open their new venue in the south of England, in the rolling Hampshire countryside, to a sell-out crowd. I got there for opening day to see it for myself and get a few minutes with the previous manager and their feelings on seeing it transition for a fairly stale pub, to heaven for petrolheads. It really does feel. like home. I pick up (again) the pricing and sales market for Porsche with some shocking discoveries. Pretty soon you'll be able to b...

This week I pick up the buzz around the Taycan Turbo GT, along with a hybrid 911 and what that means. Gunther Werks, still finding a way to develop the 993 platform which blows my mind after all this time. There's also waffle around racing a Porsche Spyder RS against an AMG SL63 and how weird that match up is! I also talk about the exciting possibility of finally achieving the goal of a lead sponsor for the RENN550 project. The entire reason Renngineering exists is to build that car! Keep your f...

James Lee from Outlaw Gear smiles, a lot! It's infectious and I realised why when I met him in person at Boxengasse 2023. Surrounded by Porsche fans, in a stunning location just outside of the Cotswolds, and with a kaleidoscope of colour parked all around. When I stopped to check myself, I realised I had the same goofy smile. That's what this culture does to you. When you immerse yourself in it, surround yourself with good people and in Outlaw Gears case, create a business to bring yourself clos...

Episode #35 Heritage | The Porsche 911 997.1 GT3 heading for the moon!

Sometimes a car gains its own following. No one really knows how it happens, but the internet lights up with chatter. This 997.1 GT3 picked up its own fan club, not because of the spec or having some fancy PTS colour, but because of the miles the car has on it (currently 188000 miles). I originally met Henry, the owner, at Goodwood during the Flat6 show, but we had been chatting on and off over the few months prior. As usual with these shoots, what was clear is that the owner was as cool as the ...
