Engines, what art the Noble mods?
Discussion
Morning all, Noble novice here.
Just after a bit of info really, could someone enlighten me as to the different specs of Noble engine available, capacity, number of turbos, peak torque and power outputs etc.
Also does anyone know in what ways the base engine is modified for fitting to the Noble? Std rods and pistons, totally rebuilt bottom end?? Is the ECU a bespoke sealed item or is a system such a Emerald3D etc where you have access to change maps etc?
Finally how avaiable are parts for the engines? Do Noble supply off the shelf items? Do you ned to own a Noble to purchase parts.
Thanks very much in advance. Matt

There are 2 current engines, both use the same 3L Ford V6 duratec block.
3-3R engine has 2 x T25 Turbos, 352bhp and 350lbft
M400 engine has 2 x T28 Turbos, 425bhp and 390lbft
ECU is a locked MBE, though Matt FP may now be able to remap this?
I'll let an expert tell you what the internals are, they are different though as the M400 runs a lower compression ratio at 8:1 compared to the standard 8.5:1. John Noble Motorsport may also be able to help as would Roush (ask for Trevor Jasper, very helpful chap).

Suggest you look at www.nobleforums.com/ they have several racers that can handle all your technical questions.
Here is the basic stuff from AER (who build the engines):
We use a custom forged aluminum piston from Wiseco which results in a compression ratio of about 8.5:1 - Interesting, I thought was 8.0:1, as per Noble literature. The little more compression probably gives a tad better pre-boost power and response. Nice little bonus, since we already got the added protection and durability of forged Wiseco's.
The rods are Scat's 4340 forged H-beam with ARP 2000 bolts. (These are not the Q-Lite version) - ARP 2000 are seriously strong, higher quality then their 8740 bolts. There's back and forth debate about H-beam vs I-beam. Regardless, Scat forged rods are bound to be way WAY more than we need at our HP levels.
Yes, they are standard green top, 42 lb Lightning injectors.
In terms of balancing and blueprinting...
Each crank is rebalanced to match the weight of the new forged rods and pistons. Each block is checked for deck height, main bore size, etc. Heads and cranks and inspected as well. Due to small variations in piston size, we measure each and every one in our climate controlled quality dept and then make very closely matched sets of six. After this, each block is honed to match the set of six pistons. We do this in order to maintain very tight control over the piston-to-bore clearance to reduce the possiblilty of piston slap from the increased clearance requirements of a forged piston.
Other items which are different:
1) The camshafts are a unique profile with increased lift and duration.
2) The block is specially machined to install piston squirters on each cylinder.
3) The accessory drive setup requires a non-stock front cover.
4) We use a special dual frequency damper for engine smoothness. This is not an underdrive or lightweight type change.
5) Lighter weight 19 lb flywheel - Looks like standard SVT Contour flywheel, which is 2lbs lighter than the non-SVT version
6) The piston squirters and turbos create increased demand for oil. A higher capacity oil pump is in the works...
