I have heard good things about your motors!

Good luck with the new business!

+1 for John Bray. Great fabricator, great engine builder, and more importantly, great guy. Anyone who uses his services won't be disappointed.

P.S. this is David BTW, John.

 

Everybody, Thank you so much for your kind words and support. This community is my family and it feels good to be in open arms! Looking forward to seeing and talking with you all. Please feel free to get with me if anybody has questions or just wants to bounce things off one another and I will do my best to provide quality information. A day of talking about Performance Porsches is a good day by far!!


And while Im on the subject, I would like to publicly thank Todd Zuccone and EVOMS for everything they have provided me with and the great times over the years. Todd is truly a great guy, and all the Zuccones have been absolutely good to me and my family. I am blessed to know them! Our friendship will always continue and I am very happy to have been given this opportunity. I will always have great support for Todd, the Zuccones, and EVOMS far into the future!!

 

Thank you sir! Not a worry. I will make sure I come find you at the next event so we can chat it up and have some fun out there racing!

 

Congrats again John! Looking forward to working with you VERY soon on the new motor

 

Congratulations sineor, wish you all the best with your new business.
Can't wait to find you breaking the records again with a new company name !

 

Thank you sir! Im ready when you are. Looking forward to it!

 

Can you develope a fuel system for the 997.2?

 

For sure. We are currently working on this option with our supporting vendor SRM who specializes in bolt on fuel options. Hard parts are done and its now in the tuning phase to run off the OEM ECU without a standalone ECU. ( though can be used with any standalone engine management system ) The system will use a Intake manifold spacer ( see pic ) with 6 additional ports for 6 port injectors. This will act as your boost fueling as well as add the addition benefit of displacing carbon build up that all these DFI cars have. The system will come complete with upgraded in-take pump, controller, wire harness, lines, fitting and rails. Everything you need to properly bolt-on fuel over 1000HP. It will be ethanol and MTBE fuel compatible with proper injector selection. Please feel free to contact me for any further info you may need!

 

Hi John,

I've been reading lots on this board and Rennlist re spun camshafts? Spoken to a few tuners here in the UK and they do not even bother pinning them for bigger 3.8 builds or even 4.1/4.2 builds. What are your thoughts and experiences on the cause as it simply doesn't see to be an issue here in the UK? Not even one reported failure.

Do you bother pinning the cams in your forged internal builds?

Thanks in advance.

Good question! Yes it is very crucial that ALL 997 ( turbo. Gt3 ) intake cams ( and exhaust cams on the GT3 997.2 ) get pinned. The process is very simple especially if you are already into the engine and have the cams exposed. Only takes less than a hour for 4 cams. We have seen many failures in the states and a matter of fact I have 4 sets of cams laying around that all have spun. It seems to happen more when a build is preformed and the cam is reinstalled without pinning. As soon as the engine runs again the cam spins and needless to say, customer not to happy. Even stock cars have spun so its not just modded engines.
The issue was supposed to be addressed by the factory but we still see it in the 997.2 GT3 with a couple of reported cases. Cant tell you why you have not seen it much over there to be honest. Cams all come from the same manufacture but I could be wrong in that statement. All my billet cams have a lock in place so they can never spin and if I do regrinds, I pin them before delivery and install.
Sorry I am not very helpful in addressing why you are not seeing it there much but I would suggest ALWAYS pinning them since its a simple process.

 

Thanks John. So if a cam has spun is it unusual for the engineer to have to fix it three consecutive times? This happened at an official Porsche dealer not along ago then at another independent Porsche house? They pinned them at the independent house and the whole sleeve spun in the end after pining the cams? Is this just the shop missing something innocuous or could the cause be something else entirely?

I agree amazing its not happening in any meaningful way in the UK.

 

Just so I am not missing something here you say that a workshop tried to fix a spun cam 3 different times?? Once the cam is spun, it needs to be replaced. The reason why is because the only way to pin it correctly is to make sure the pin drives through the outer and inner sleeve on the rear ( Closest to the lobes ) set of holes. If the cam spun, these holes will not line up anymore and a pin can not be driven through. Some times the inner sleeve spins just slightly and you can re dill through it and drive a pin in it but I only recommend that if there is just a slight misalignment. I have never tried to just drill new holes all the way through as these are oil galleries we are talking about but it maybe fine that way.
So maybe when it spun originally the tech put a pin in it but failed to get it all the way through both parts resulting in spinning further so on so forth. Otherwise there is something else that needs to be diag. But you can clearly see if the cam is ok because you can see straight through the rear set of holes down through the other side.

 

Okay thanks. It happened to a few other members on this forum so I'll let them chime in if they want to. I was v.surprised both members engines needed stripping three times. One was under Porsche warranty so not an issue but the other member has to pay his shop labour for three engine strips which seems a tad unfair.

I'm at a loss why we haven't seen this in UK. My tuner has circa 800 996/997 turbo customers and not one issue. Spoke to my local official Porsche service manager too which is the largest in UK and same thing not one cam issue in 16 years and only 4 total engine failures.

 

Ouch!! 3 times is crazy. Not cool at all.
Yeah I would like to look into it more and find out why it seems to be a US thing ( for the bulk of it ). I have seen allot mostly because of the pure number of engines I have had my hands on but honestly have not researched it past my own dealings. I would very much like to know so if anybody has seem issues elsewhere across the world I would love to hear about it.
