AJP v8 4.5 into 450 chimaera

[richarddorman]

I have been looking at the supercharged route which is going to cost around 5k giving me about 350bhp and 357ft/lbs in my 450 chimaera. Wanting to stay with all that is TVR so a 4.5 AJP seems like a good road to go down with less weight more bhp than sc rv8 not sure on the torque figure.What can i buy a good 4.5 ajp for and what is my 4.5 RV8 with 30000miles ecu tornado chip carbon trumpets large air flow meter going to sell for

Just FYI my 450 SC showed 372 bhp (309 at the wheel) and 390 ft/lbs torque. This is before the mapping has been fully sorted, so may be able to squeeze a little more shortly.

Hi Richard, there is a third way, larger capacity will give you those sort of figures and with lot less grief than the AJP route (I did a fair amount of research)

oo I don't know .. I have a large capacity RV8 in at the moment, 5.3 or 5.4 or something .. makes nearly 350hp and 380lb.ft. the ajp8 will get you the same torque but 50-60 more hp. To get 410hp from a RV8 would take some doing, and some money and it still wouldnt rev to 8k! The AJP8 conversion makes a lot of sense, if you do the work yourself it's relatively cheap too. You could have one in your car for about 6k I reckon including buying the engine. 410hp from a normally aspirated RV8 for 6k? I doubt it .. i think you'd struggle to supercharge to 410hp for that money too.

OTOH, Steve Heath reckons he can do you a drive in/drive out Corvette engine conversion, like his Cerbera (Corbera? Cervette?) I was looking at yesterday, for £7K. 400 hp, 30 mpg and 100K service intervals. And a bombproof engine, with a huge range of tuning options and places that will work on it.

the ajp may be very powerfull but they take alot more looking after ,its a full race spec engine and a rebuild costs alot more than the rv8.a chap down the road as one in is cerb think its 4.2 its sounds very tapperty and hes looking at spending 5k on it for a rebuild and its only done 45000 miles .

That seems awfully cheap?

I assume that is with the punter buying all the bits needed, therefore the £7000 is just in labour?

Nope. That's it. Engine, labour, everything. OK, it's a second-hand Chevy, and I imagine they keep your Rover, but Steve's told me that figure twice now. Drive in with a Rover and out with a Chevy. The installation in his Cerbera looks very nice.

Not quite true. The figures are certainly true for a Cerbera but not a Chimaera. The reason is that with the Cerbera conversion we can reuse all the bits once the engine has been taken out. i.e. bellhousing, clutch, ECU + loom and so on. With a Chimaera... this isn't possible so the costs do go up quite a bit as a lot more mods and bits are needed.

However... having has Cerberas with several AJPs (gives you a clue why I went with an LS) and the current Corbera Cervette, I would go with the LS anyday.
