Future-proofing the AJP
Discussion
So what's the first thing you talk about when you are allowed to visit the pub again ?
Future-proofing the future of our Carbon-gusling P&Js !
(Ok, maybe it wasn't the first thing)
but there were quite a few nationalities involved, in an emptional way, in the subject, several of whom had engineering backgrounds.
Eventually it was decided that it was possible to produce replacement Cylinder Heads for the AJP8 for €1,000 a pop.
Do you think that there'd be a market ?

Al Melling was giving them out at the Middle Wallop meeting a few years ago.
I have one somewhere..

Good Post I have one somewhere..

BUT
Isn't that for the 6 only ??

1k per head?? If I could get new ones made for that little then I would be a buyer!
I can get new cranks made and blocks made, pistons are easy and rods are readily available. Just the heads left

Mike, You are a STAR !I can get new cranks made and blocks made, pistons are easy and rods are readily available. Just the heads left
Mike
I knew that there would be someone out there with some sense
Unfortunately 2 customers doesn't make much of a market
BUT
If anything progresses I'll let you know
Oh, by the by, where did you get these made up ?
They are the best quality I've ever known and was thinking of ordering a personal design.
Ta !
Sorry, re-posting this as I deleted it by mistake....
For those of you who aren't interested in FaceBook, here are some comments from Mr. Melling, (The designer of the AJP8), that can be found on his 'Musings' account.
"Ok its now time for you guys to sort this.
We have been trying ,with lots of ideas to get an inexpensive cylinder heads, as you know you guys sent me a pair of heads, which shortly will have to be returned.
Our cost to date is just over £12k and course i want to get this completed.
1 Its very difficult to make the heads in billet ,looking at the section drawings you can imagine, but say if you insists ,then by lifting the cam and longer valves it can be done ,but then a new cam cover will be required.
To machine this would be -for the CNC model say £3000 For the actual machining 2 items £4000 =£8000pair.
The tooling initial £5000
So the full cost of the first pair would be £16000.
Future would be £8000.
If your going to get a number of you then the machine company may amortise the cost of the model and the tooling. Say £1000 on each pair delivered.
I am now looking .giving it ,more time.
2 the existing cylinder head design and casting them.
A pair of existing cylinder heads to be used as a sample and get a pattern company (there are lots in the internet,) and they stick machining allowance on the joint faces and then make a water jacket core ,the foundry can cast them, this is a very inexpensive way of casting . The castings you find a small business guy to machine them with a Bridgeport Mill and he machines them at a budget price, all you require to machine them is that mill and a boring head and 90 degree atachment. Any questions on this i can speak to the people doing the job.
3 if you decide to go for cast cylinder heads then (looking at the scruffy drawing ) you can see an outline in red ,that is the existing inlet port and valve position.the black line inlet port and valve is a suggestion to increase power and fuel consumption, this new port would give you another 35/40bhp. IF YOU WANT .this modification does not effect the exhausts or inlet ,or throttle body,
this modification can be done to your existing cylinder heads, let me know.
Initial pattern work £500, water jacket pattern £2500,machining £ 4000, casting £1000pair.
Initial cost £7000 .
Production £5000 pair.
4 A 4 valve pair of heads in billet would be about the same as the 2 valve, on cost and unit costs , easier and quicker,but the problem is it would need a new timing cover (inexpensive ) and cam cover ( inexpensive) but you would have over 500bhp ,a 4.2 with 460bhp.
I want you to decide what you want to do. And let me know. Get talking to the people who wanted new cylinder heads.
Also the heads you have what is wrong with them, get intouch with me."
