For those of you who weren't into this in '98, here is an article from 911 & Porsche world issue 51 Back issues can still be got I think.
This is what a real 530hp tt 911 with 5 speed gearbox, ~1500kg and fancy aerodynamics can do. The new Ruf RT12 is only 0.4s quicker to 124mph despite its 650hp - makes you think
BTW check out the typo on the torque #

Interesting article. Tal's car had the 964 C4 5spd gearbox still in the car when I tuned it. I thought that it might be a problem with the power, but it seems fine and I really liked the shorter gearset when I drove the car and made it very responsive. I do notice that the RS tuning car runs to 221mph, so they must have changed the gear ratios in the trans.

The 754RSNM ~554lb/ft required $3500 (at 1995 prices) worth of gearbox mods to extend the top gear and to cope with the torque.

I wondered why it was a 5-speed and then saw the interior, it is 964 based.
WOW, very cool!!

Good article

TB I had been looking for that article for about 2 years and finally got hold of it last month, now you post it!! Thanks for posting.

I think the important message here is that a good builder is the one who can put the right package together to build a well balanced sick car. That 0-300kph is close to what the 700+ 9FF car does with all the water injection gizmos etc... 6-7 years later and on a much more efficient watercooled engine.

Also interesting to see how the 5 speed gearbox performs. The two fastest quartermile Porsche in the US that I know of, both have 5 speed boxes, with trap speeds reaching the 150+ mph in 9+ seconds.

Hmmm..next mod? the gearbox would be lighter too!

1000 lb/ft of torque @ 4750 rpm means the engine is producing over 900 hp at that engine speed.

Always good to read your posts, you should chime in more often.

Where is the technological progress with all those blown up 996 turbos?

The 996 GT 2 with 525 hp and also 750NM I drove again today is not even close to this rocket. Neither in acceleration nor in top speed.

What is the weight of that car? ~ 1400kg?
What intercooler is that?

The car was tested by Sport Auto, it is the one on this site, tested in 1997:

Weight is 1492kg according to Sport Auto test.
The intercooler has "Behr" written on the cores.

Behr = Secan. They work jointly.

Thank you for posting the article. I'll go look for issue 51 and hope I have it.
