Most HP with a Noble?
Discussion
We've been doing some pretty cool stuff trying to increase the HP on the Noble.
Does anyone know what is the greatest HP and Torque achieved on a Noble????
At the wheels would be a preferable reference number.
Before the lectures begin about not needing additional HP, this is primarily a track car. Additionally, some of us are a little heavier than others and HP is the best way to overcome the disadvantage(good driving helps also).
Ok... I'm also in the US.
MORE IS ALWAYS BETTER!

We've been able to get 409Hp @ 5750 RPM at the wheels measured with a Mustang Dyno. Max Torque is 376 @ 5500 RPM.
As a point of reference... The same Dyno measured a "stock" 3R with Max HP 263 @ 6000RPM and Max Torque 272 @ 4750RPM.

I'm confused. That's a 25% transmission loss. Most 4WD setups are more efficient that that!
Anyone else had their car on a rolling road and have a wheel output?
NobleYank: Are you saying that you have recorded 409bhp at the wheels? If so you MUST tell us more.

Yes, 282 at the wheel, calculated 340.5 at the engine and 316lb/ft of torque.
That was done on a Sun dyno and for a lowly 2.5l car (albeit upgraded by the factory).
If anyone is interested I have the dyno plot scanned in which I can email.

This has confirmed what I thought. A 17% power loss is much more like it. Still can't understand why a standard 3R recorded such a low figure.
Intersting stuff Joust!
Has anyone here replaced the fly wheel in the 3R? I understand its about 25lbs.
How did the car feel with this change? How noticable is it? How much did it cost. I think the flywheel (aluminium or aluminum) is $600...but the cost to install would be around $1000.
I noticed that the M400 has a lighter flywheel.

It is possible to get over 450bhp with the twin turbo arrangement for sure, but the MMT6 can't take more than about 400lbft sustained grief before the retainer pops a hole in the casing. (The shaft torsion undoes the retaining bolt) So unless its tuned for all the power at high revs (so that the torque not in the low end), and correct me if I'm wrong but IMHO its a bit pointless risking your box I would have thought?
Flywheel wise, ask AP racing what they can get for you. I personally feel that the standard flywheel is a bit heavier than it could be. But resorting to Ali for a road one seems a bit too much of a compromise, besides it'll probs need a remap.

Dynos are well known for being inaccurate and "non absolute". Its not sensible to compare the final figures from any two dynos. The only usefull comparison is to do the car before and after on the same dyno. Then quote % changes. If you want to meaningfully compare two dynos you'd need to take the same car with the same setup and at same ambients and run it on them both and then calibrate the two.
Some of these guys from the USA have made 1,000 hp from the V6.
The limiting issue is the gearbox. It ought to be easy enough to get 500 hp out of the engine with littel effort but remember Lee blew gearboxes two a penny last year.
If you want to go above 450 hp you need to source a new gearbox to take the power.
