There is already one running or so I was told by the person that built it.

Who was that ?

[Gazzab]

Not my place to divulge - he asked me if I thought there was a market. I said there werent many cerbera owners willing to spend the money.

I hope that they can get it working as its a great project. What I find difficult to understand is why you would invest so much time and money in a 32 valve AJP. If I wanted 32 valves it would be much easier to go and buy a crate all alloy mustang engine (or a dozen other ones that are available) ...well proven, reliable, cheap, powerful, tunable. just dont get where the market is.

I think the whole point of this project/engine
Is that it will be very compact
Poss the most power to Waite to size engine
Out
The trouble with ls/ford engines they have no flat plain crank
They are heavy and large and and the ford is under powers
Unless you put in a lot of work and money
The crank in the ajp is what makes the cerb what it is

[Gazzab]

I'd love one of these...not sure I'd want to be the guinea pig.

I said the same thing to the same person. They intimated they weren't going to take it any further so I'm surprised its gone ahead.

It's pure spirit of TVR.

It's the what if?

It's, I wonder if we could?

Common sense and a market doesn't come into it.

It's like.... "I wonder what a supercharged AJP would go like?"

I expect you get it now Paul?

Thanks for that ride up the M1 by the way, it will stay with me forever

I appreciate most of what you said, the supercharger project on mine was purely for fun, my hobby is my cars and as such I dont really care how much time and money I spend on them. I presume the 4 valve project is a commmercial venture (sorry if I got this bit wrong)so it must be considered with this in mind. I really do hope they get it working as it could offer another tuning option, just looks like it might be expensive. anyway good luck who ever it is

[longbow]

Won't fit in a TVR chassis though...... too wide at the top as far as I can tell......

[bionicjim]

It will fit defo

[gruffalo]

a 4.7 done properly costs £7 to £10K depending on what you spec to be done. If this costs must the same delivering the same sort of power increase plus the better tractability of a 32 valve engine then I want one but in 4.7 form:-)

It would be the ultimate AJP in my book.

Who do I contact to get mine built?

[bionicjim]

Hi mate I need to check I will let you know

let everybody know post it on here!!!

[DAVEY DEE]

I wouldn't want anything posted up until I knew it all worked if I was building it.Then again,if I was building it it wouldn't work!

I call custard. Pics or it never happened.

This looks like a very interesting project to me...

Does anyone know if these heads are bespoke or if they have come from another engine?

I can imagine that, if the heads are bespoke, the full engine may be more compact/ lighter than anything out there.

If they have come from another engine (let's say something like an Audi RS4) then I can't see why the 'donor' engine would be a lot less compact. I guess it may be more to do with packaging (the narrower V of the AJP) but this seems like a very expensive way (although very cool and I love this type of project, hence why I have checked in) of achieving more NA power when we know LSx engines fit etc. This won't be a cheap solution!

However, don't take this at all negtaively! I love this kind of project and the AJP is one of my favourite engines, hence why I lurk here.

[gruffalo]

I want one of these because the Cerbera is all about the AJP and the AJP is all Cerbera, more valves and a 4.7 seems to me to be a marriage of ideals and I am sorry just putting a big US lump in a Cerbera seems to lose the pure, no compromise feel of a Cerbera and the AJP.

[jamieduff1981]

Agreed. The Chevy engine has everything going for it but for some reason it just leaves me cold. I can't see the appeal in fitting one to an eccentric British sports car personally, but each to his own and all that.

I'm a big fan of the AJP8 now mine actually works, but I'm not going to criticise anyone who's put an LS in theirs after their AJP let go. I doubt there are many people who have LS powered Cerbs who have removed working AJPs, and it just means that there are more spares for the rest of us.
