Sorry to hear about your problem! Get it back in shape ASAP....

 

+1 on this . I fail to understand why guys try to spend tons of money on a fast GT car like 996tt by reducing 400 + lbs of weight and improving handling etc...instead of getting a 997 GT3 or RS which serves the purpose well out of the box.

 

Let me educate you:

The reason is because most all of the guys in GT3/RS's are putting the same upgrades on their GT3's that we put on our turbos (fact) (in fact, exact same parts). The other fact is that the GT3/RS is a great street/track car, but still leaves quite a bit to be desired on the suspension once you add sticky tires. And trying to get more power out of it is a joke.

A GT3 is more of a spec type street/race car. Upgrading it get's you little progress.

I can tell you this, Al Norton has basic suspension/aero upgrades that you'd find on a 997 Cup (with far less development, most work done at home) and drives around Road Atlanta with PSM on to laps only 3 seconds behind the fastest ALMS Cup challenge guys. He could easily run his 3200 lb turbo mid pack in a challenge sprint race. And Al is no pro driver, a pro guy would be top 2 easily (which is only 2 seconds faster than Al) Waiting for him to let me drive it one time till mine is up to that level.

Try that in a GT3.......... Either you'd better be Walter Himself, or ready to spend as much as a Cup Car to get there.

The GT3 is a great car, but to compete with the modded Z06's, ZR-1's, Vipers, GT-R's of the world, it just wont cut it unless you buy a cup car and can drive at a near pro level. And you can't drive that on the street like those cars/we can.

 

I liken the cars to something like the difference between a Spec Race series to something like Can Am where its no holds barred. The GT3 is a great out of the box " spec " style race car. But if you have the dough the TT makes a better " unlimited " style race car.

 

Thanks for the information. My friend purchased a 996 GT3 cup car for 70K (i think) after giving up modding his 996tt to the cup standards. But i agree with you with the 996tt you can drive it on the street and still be a killer on the track with correct mods.

How much hp does Al's car make to keep up with ALMS cars? guessing in the 600 hp+ range? Dont cup cars weigh under 2800 lbs with 450 hp?

What are the competitive class out there that is there for racing modded z06, zr1 other than OLA?

 

It's funny because Al started his car off as a 60-130 build, he wanted the fastest car on the list. THEN he made the mistake of going to the road course a few times and was totally converted.

His motor is built and he's running some hybrid turbo of come sort with EBC etc. It COULD make 700 whp+ but ever since he's been on the track he's been dialing it further and further back for preservation. Right now he's only running around 1.3 bar (I think) which with those turbos I think puts him around 550-600 whp? Not to sure, but it's FAST. He's trying to get rid of the EBC and dial it back some more with a new tune. The EBC allows him to run LESS boost than the tune would. When that EBC comes off it's straight to 700 whp unless he gets a new flash.

As for classes you won't find many ZR-1's racing, but they are at many track events going fast. Mostly fast C5 and C6Z's, Viper, GT-R's, ACR's at those track events as well as racing in NASA, PBOC and some in SCCA. More of all of the above in NASA time Trials.

 

I agree with Dez. People have the misconception that the turbo is slow at the track and you should get a gt3 or a gt2. I like the lines of the Turbo over the gt3 better. The turbo is a lot cheapter than the gt2 and with that money saved you can make a road track beast.

As for the Turbo being slow, lets ask this 360 Challenge car





Or


This GTR









OR




This GT3 with motons + $$$

 

Attaboy!!!!!

 

Because a picture of a car at the track tells the whole story.. LOL

 

No, but the driver posting the picture and knowing the the story does.

 

Umm can you please clarify how an EBC is allowing for less boost than the W/G?

 

take away the EB and run stock springs... that will give him 1.1 bar sustained... it is hard to dial in a 1 bar spring so that it runs only 1 bar all the time... thus a EBC allows you to go up in boost but not less then what the spring rate is...

 

Agree & Disagree with this comment... Stock for Stock on Corner speed a GT3 or RS will wipe the floor and embarrass a Turbo, they are way lighter, sit way lower (uprights, mounting points, etc), lower centre of gravity, LSD, etc, etc... It would depend a lot which circuit you were on, long straights for the Turbo or short for the GT3... I would say 90% of the Tracks around Europe the GT3 or RS is the car to have, I have no doubt about that.
Even when you start modding a Turbo, there is **** load of work to do to get even close to what a GT3 or RS is capable of.
The perfect example is The Ring, on the majority of corners you have speeds anywhere between 60 and 110, the GT3 is perfect for this, you can keep the revs on the car and it drives through it smoothly, with the Turbo you have to work extremely hard to keep it in that zone... I have found myself turning boost way down to get quicker lap times as you require the car to be less aggressive.
The likes of SPA is a different story, the Turbo/GT2 performs well, long straights where the car can just open up, a well set up GT2 will be quick around SPA

 

Nope, just stating what he told me, I may have mixed it up some, so take it with a grain of salt.

He has external WG's if that makes a difference.

 

Type of track always matters. However we are talking about well set up Turbos here. 997 GT3's weigh well over 3200 lbs, all it takes is a few light weight mods to get a 996 TT there so weight is not an issue.

The turbo will not match apex speeds, but it doesn't have to, late apex, early on gas and you can catch the GT3 by the time it upshifts. The main issue isn't the cornering, it's the braking, a GT3 can make up most of the distance you gain on the straight in the braking zone.

Does not take a ton of work to beat GT3/RS in a TT, all it takes is coilovers and a rear sway and it's pretty easy. It also takes less skill to extrapolate the potential of the TT.

I haven't had any problems with pro drivers from Europe and US in GT3's, and comparing data, my entry speeds are the same, my apex speeds are quite a bit slower, but close enough that my 500 lb/ft can catch and then pull away on exit.

One thing I will say is that it IS NOT easy AT ALL to keep a GT3 in the powerband, you have to almost powershift to keep the revs from dropping too low between shifts.
