Tony just emailed the GIF images straight from the dyno. These are easier to read:

I hope their remapping skills are significantly better than their ability to set the date on their PC.

Undoubtedly

You must be pretty pleased with the results, particularly in the context of the others models you have quoted above. Congrats, glad you got a good result...any plans to try and eek any more power from it?

hmm, looks like it needs a higher rev limit! Power still climbing ;-)

[Vitorio]

better power/weight then any 430 and the standard 458, proper job!

did they do a run before? would be good to see a before and after. Even more interesting did you do a power run before any of the mods? The power output does seem a little erm "high" considering the modifications? If they can get this out of your engine then in theory they could get ~600 out of a scud?

It wasn't possible to get a baseline with my car because the starting ignition settings were not suitable for a power run. A Scuderia modified to identical spec as my car but with the 11.9:1 compression ratio would be within 5-8hp with some more torque in the mid range; a 0.6:1 increase in CR would not make a significant difference.

For reference a fellow CS member took his F430 to DMS in Jan, and here is his baseline:


That's in the reigon I'd expect for a standard F430. I spoke to DMS about the factory tune and it isn't without issue: the AFR on a 16M they had in a couple of weeks ago hit 17:1 in places above 4krpm.

I've said a few times above: dyno figures aren't worth getting hung up on - the only dyno I really trust is an engine dyno - but for the purposes of comparison in my power to weight calcs above it is OK, because Ferrari's rarely make the factory claimed figures (nor weights).

Super updates as always !!!

[PhillipM]

As Max said, that really looks like it's crying out for a higher rev limit - is there any more to go or you at the max of what it'll take to maintain day-to-day reliability?

I wouldn't want to go past the standard rev limit with standard rods; the big end becomes oval and the result is a rod through the block. If I'm opening the engine to fit stronger rods I wouldn't keep the F430 crank nor many other things, so I'd rather wait to finish a complete engine build in one go.

Damn laws of physics, getting in the way of more fun.

Well, this is quite a thread! Thank you for sharing all of your experiences in such detail, and of course as others have said, hats off for treating it like the lump of metal and plastic it is ;-) I'm also a huge advocate of the fact that an enthusiastic amateur will often do a better job than a professional.

I'm collecting one of these next week (well, a standard one!) and while I haven't got the inclination to rip it apart as much as you have, it's been absolutely brilliant to see under the skin of the car and just how easy they are to work on. I'll chuck it on my scales whinnies get chance, to give you some extra data for your bhp/ton calculations.

Thanks again - owe you a beer or two if we ever meet

Adam

Thanks Alex - cracking photos! You caught mine before the valets visited; there's a couple of months worth of dust and summer road grime there

It's fine, they wiped all the dust off, with that white towel on the floor and those Autosmart cans.....

am I reading the graph wrong - it ends below the 430 rev limited, doesn't it? I thought the the rev limit is at c. 8.5k rpm

I always forget how good looking these cars are until I see one again. What a superb machine.

Have you any long trips planned this summer/autumn?
