In the Feb. 2004 issue of GT Purely Porsche they test drive RUF's 590 hp R Turbo.

I'm a bit dissapointed because they test drive this wonderful beast and all they descibe it as is 'faster than the 520 and 550 hp convesrions.' Yeah? I'm sooo surprised and it makes me think did they go to Germany just to make a quick drive and take some nice photos? Also why have the Cayenne V6 on the front page covered in snow when there's nice RUF piccies around?

In any case Mr. RUF mentions they had an expensive lesson as the torque increased in the engine. At 612 lb ft torque the steel was bending so they had to go for titanium conrods to avoid any Uri Geller misadventure... The steel conrods bent and touched the cylinder sleeves but didn't break apart. That would have been an even more expensive lesson.

This makes me wonder, since I guess RUF is one of few tuners that use titanium conrods (?) how about the real torque output your tuner claims vs. steel conrods? Is the torque less thain claimed or are their conrods goind to bend as time goes by?
Looking forward to your feedback on that one.

I have that issue and read that article, Riviera Blus is very bold, I prefer Gulf Blue personally.

 

That's concerning....what are those of you that have 600+hp mods thinking about your steel conrods right about now?

 

Hey Buddy,
Did Titanium come with that Stage 5??

 

This was a weak review on GTPP's side, in addition I am pretty sure this is a wide body but they claim it is a narrow body, big mistake for a strictly Porsche mag to make.

 

Really?

Is the car on these pics really a wide body?

Im not sure if thats a sarcastic remark, but yes it is definitely a wide body from C4S shell.

 

I believe our local tuners are aware of the 600 TQ engine stress threshold. I've been told the threshold is an 'at the wheel' vs 'at the crank' threshold. I am assuming that the 600 TQ number quoted in the article is wheel torque, where as the 670 TQ produced by the Stage 4 GTR, for example, is only crank TQ.

Nope, my bad. I thought you meant it was wider than the stock 996 Turbo - but I guess it's not?

 

Stage 4GTR actually has 706TQ...
where as Stage 4GT has 670TQ
hm... now that start to make me nervous ....

maybe I should not push my car too hard b4 I upgrade my engine internal...

Is Ruf talking about 612TQ at wheels? I believe they're more likely to be talking about on crank TQ

 

I have the GT/R components in boxes waiting for installation. I agree with your hessitation on pushing the car for too long on the GTR 'race gas' program. I plan on using button #3 very sparingly.

The need for Ti rods at that level is a bit surprising.

The general rule here is that the stock rods weakness can be overcome by shot-peening (reducing the inclusions). Another option is to go Billet, but in doing so you decrease the strength at the crank end.

Regardless, while Ti rods are inherently stronger, there are a number of folks making upwards of 700 WHP in various iterations of the 911 Boxer using the stock rods ....

Given the price tags associated with anything RUF, I would not be surprised if they went this route simply for the added safety -- and price.

 

This car is widebody turbo version

I really like the colour also

all the best

Tell me, is there a RUF you don't like?

 

The REDBEAST is having internal surgery to cope with this!
