I have a Mustang background, so im used to fairly immediate torque. As hard as I try, I keep coming back to interest in a 911 and preferably a turbo (has to be faster than my current mustang). What im concerned about though is lag... did Porsche improve this with the 964's?

Also how do they hold up in open track situations? ie heating up? brake pads?

Yes they do still suffer from fairly significant lag as will any turbo expcept the Twin Turbos.

Lots of ways to minimize the lag: upgrade the turbo from stock, freeflow headers, electronic boost control, etc.

I don't see the problem though unless you plan to drag race the car. On a track and even the street, it is not a problem to keep the revs up so that boost can be almost immediate.

You need to drive some Turbos - there is a huge difference between Mustangs (even modded) and Porsches

There is no better braking car out there than the 911. The '91 Turbo has a breaking system that equates to 1700hp ! It will out break consistantly without fade any car on the market. Most Mustangs I have come accross seem to really enjoy burning rubber off the line... I guess thats their equivalent of Tubo Lag!!!! Drive a Porsche you will never go back!

A stock 964T behave very well on track days. No problem with motor or oil temp even on warm days. Stock brakes are strong and good enough. At the end of 20 min sessions I had a bit of fade on a rather fast track.

May be not the easiest car to drive on a track but very rewarding fast and more importantly FUNNN <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

 

The earlier 930's came with the K26 turbo which did have a lot of lag but the 964 3.3 turbos come with the K27 turbo which does spool up much quicker. Many 930 owners do upgrade to the K27 turbo which eliminates a lot of turbo lag.

 

Also, it wasn't until 1989 the 5 shift gearbox was introduced on the 911 turbo, it's hard to keep the boost up with 4 gears.

I think the 964 turbo is a great track car, a little heavy, but there are a lot of things to remove

The turbo lag doesn't bother me to much on the track, kind of feels that you get even on the straights <img src="graemlins/roflmao.gif" border="0" alt="[hiha]" />

Brake fluid getting to hot is my only problem, the brake pedal gets soft but I have never noticed any loss in braking force. Brake ducts would probably take care of this problem, it's on my "do it or not" list.

The stock 964 turbo wheel alignment is very lame, to have good grip on the track you need to dial in lots of camber.

Clarke, go for a testdrive, this thing is glued to the ground.

 

Hello

I have to agree with the general sentiments! The 964 Turbo is one hell of a car.

On the road, under 3000rpm, it's so mild my granny could drive it , but get behind a slower car, wait for the smallest gap in the traffic and WOOOSH - nothing like it <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" /> !

On the track, this car really shines. It is so very well balanced, without being boring. Still has some of that kick-in-the-pants excitement for years gone by, but delivers it so wonderfully it's breathtaking.
The Turbo lag is there, but get used to it, and it is one of those lovely tools that become available to lead your opposition into a sense of false security. Just as you exit the corner, they think they have you, and then the boost comes in.... <img src="graemlins/burnout.gif" border="0" alt="[burnout]" /> . And it is see you later!

And the brakes! Let me put it this way, I also have a 944S. When breaking into turn one at Calder Raceway here Downunder, in the 944 I start somewhere around the 250m mark. In the Turbo, I slam on the anchors at 150m, almost engage ABS, and wind through the right hander much faster than I can in the 944.

This is the car that goes from 0-100km/h AND BACK in 7.1 seconds! <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" />

I had the car out at Winton (another Ozzie raceway) and hammered her ( you know what I mean) for 30 minutes without a slow lap in between, and no brake fade!

I love my car... can you tell <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

 

I agree with others and just like to add from my experience.

I've owned my C2 Turbo for over 2 years now. It was totally stock when I bought it. I too did not like the low rpm turbo lag. But after I removed the right side muffler and replaced with a J-pipe, the car responed a little better with the throttle and quicken the turbo lag a little. After that, I added a Rice fuel enrichment device and the car is much more responsive. I consider the turbo lag now is very liveable and have no problem with it driving around town.

Regards,

Sonny
ps: Of course, headers, sport muffler, no cat, and better turbo can really help with turbo lag.

 

Thanks for the replies. I totally agree that i need to get out and actually drive one on the track. In all honesty I have yet to drive any Porsche. Im glad to hear that they hold up well stock in an open track environment... that is the main reason the mustang required so many mods... stock they are not really road course worthy once you get the hang of it.
