Stew F Posted 31March, 2018 Report Share Posted 31March, 2018 Hey team. As some of you may have seen on social media, my fan housing and fan are quite badly damaged. I need to talk to a welder on Tuesday, but in the event that I have to replace them, I have a couple of questions. Q. I have a 226mm fan. All the new housings seem to be 245mm. Can I fit a 245mm housing onto my engine? Of course, I will have to get a 245mm impeller as well. Q. Where can I buy alternator brushes for a Valco alternator? If you are curious about what the damage looks like, check out the pics on my Instagram page @that_porsche_guy, or my Facebook page @stewfuchs.

MFX Posted 31March, 2018 Report Share Posted 31March, 2018 There is a company in Qld (can't remember the name off hand) who rewind the old alternators, and they can up the amperage while they are there. I have a 5 blade fan if you want it (doubt it ). Also have a 245mm housing with a small chip on the rim, would still function fine, just not as pretty as I wanted.

I'll pm you about the 245mm housing. Link to comment Share on other sites More sharing options...

Peter M Posted 31March, 2018 Report Share Posted 31March, 2018 Are the Valeo's that bad to buy as a replacement? Read a lot of negative comments about them but never a firsthand accounts of one failing. Although it looks like a new Valeo would work out about the same cost as a K3 from PR Tech delivered.

Jonny Retrofit Posted 31March, 2018 Report Share Posted 31March, 2018 I think if you have an early SC with the 226 fan housing, you'd have to change the engine shroud too to go to 245. The main issue with 'rewinding' the standard alternator for higher output is heat. There are no internal fans in the original units and the air flow is poor. Ironically, the engine fan encases the alternator , preventing cooling. We have melted several supposedly high output units. Yes, they make the power, but eventually self destruct. We currently have a completely new design in test. It has internal fans and is a modern six phase unit. We've measured over 80A at idle and managed 145A on load with the standard single pulley. It will be expensive compared to a rewind. Link to comment Share on other sites More sharing options...
3legs Posted 1April, 2018 Report Share Posted 1April, 2018 Hey Stew I use a bloke down Kilkenny way who does all my aluminium welding. He does all types of welding and is very, very good at it. He can be a bit expensive but his work is first class and I doubt you would never need to send it back. His business is called "Tig on welding" His name is Sam. Tell him I sent you.

Read a lot of negative comments about them but never a firsthand accounts of one failing. They were, and still are, fitted as original equipment by quite a number of car manufacturers. Ashdown Ingram is the Australian distributor for Valeo I believe. Valeo is the modern whole of beand name of the company formerly known as SAFF, who owned brands we're used to seeing on our Porsches, like Marchal, Paris-Rhône and Cibié.

That is what I thought when I called them (although it was around 12 months ago). I just got slack and haven't sent it up to them yet. I suppose it is hard to stay motivated without an engine Link to comment Share on other sites More sharing options...
Stew F Posted 3April, 2018 Author Report Share Posted 3April, 2018 Last night, in a moment of weakness and despair, i shelled out nearly 500 AU clams on one of those EPS hybrid impellers. Apparently they flow around 30% more air with no more parasitic load on the engine. Link to comment Share on other sites More sharing options...

Stew F Posted 8April, 2018 Author Report Share Posted 8April, 2018 When I get it all fitted I'll have to conduct some comparison testing and post the results. Of course that means lots of driving under controlled conditions. Sent from my LG-H815 using Tapatalk Link to comment Share on other sites More sharing options...
