Sure.

Just got my GT2 Clubsport back about a week ago from Ruf, having had it upgraded from 550bhp to the 590bhp Nardo package (mine actually dynoed 620bhp on the engine dyno at Ruf).

It is incredible, the Nardo engine has a totally different feel to the 550bhp Ruf engine, it is much more responsive. The titanium con-rods help reduce inertia as does the lightweight flywheel I had fitted. This car just pulls and pulls.

The day after I got it back it was videoed by Tiff Needell for the UK programme 5th gear at the VMax event, which I won by just beating Adams Yellowbird by 1mph (195mph over a standing circa 1.5miles). Picture below:



Programme is showing here on TV next week.

I run Pirelli Corsas full-time, which are a bit tricky in the wet/cold here sometimes - I got wheelspin in 6th gear at 120mph a few weeks ago on the road.....

According to the Ruf test-driver, the car slams into the rev-limiter in 6th so hard (at about 206mph) that it actually de-stabilises the car.

My car runs over negative 3 degrees camber all round permanently and has the Manthey Racing strut-tops to increase castor. The turn-in is razor sharp, but at the expense of high speed stability, it can get a bit jittery at speeds over 200mph indictated (which I only do on runways, not public roads).

The Nardo engine is very trick and has a ton of parts fitted/changed that people don't know about, but is very expensive.

ok nooooow u r my new hero:P That is a great write up.. thanks for sharing!

The only thing about Ti rods is their longevity. There's no doubting their lightness but that's all I would be concerned about

 

Yes, but the nice thing is that Ruf thoroughly tests their stuff and they back up their work.

Sharky, why don't you think titanium would last for 620hp?

BTW, I bet you the Nardo is faster than a lot of the tuners' "700hp" packages.

 

MUCH

 

You could ask Todd at Protomotive the same question but just too many people that I respect have told me the same things. Even when the Peterson White Lightning Race team was at our shop doing a tear down/rebuild for the next race the guys there told me about Ti rods not being good for a street car and longevity. Hence I went with Carillos.

If it's 620hp crank then that'd be different I guess but Porsche didn't fit the GT2s with them in the first place like they did with the GT3 (which obviously has way less torque).

If RuF has done testing the Nardo for 60K with no issues with the Ti Rods then more power to them

 

Oh and all the rules get thrown out as Ben said once you factor in the MONKEYTRONIC....

 

There's a longer write-up here:

Ruf went titanium because they were bending the stock steel rods. They have some Nardo customer cars that have done over 60,000miles already.

The other thing is every car Ruf build is driven to it's absolute maximum on the autobahn and they will hold speeds of in excess of 200mph for a minute (or more) if they can. Their engines are built to last at these speeds, not just produce a great dyno-chart.

The Nardo is a full strip/rebuild with many, many very-cool custom Ruf parts added, that most people will never know about.

That's awesome and I'll check it out then. It's too bad stuff has to remain so secret but I can understand that...

I didn't know that about the Nardo stuff but perhaps Chad can explain why he didn't end up using his RuF Ti' rods...

I didn't know some of the RuF Nardos had over 60k on them

 

I don't they are secret specifically, but it's the German way of doing things and Ruf's in particular is to do a lot of research and engineering, build a package that works and lasts and then not be very disclosive about the details of what they've actually done.

It probably because they are sellers of complete cars that they have this attitude (which I like) so they have to design and build packages that drive with the quality and longevity the same as factory Porsches.

The opposite from this is where there are sellers of parts that people add to cars, like the Jap-car scene where no two cars are the same, every one mixes parts and consequently few ever work as a cohesive package.

As for Chad's car, thats aiming for so much higher a power level that his requirements probably changed the desired material and design.
