Also keep in mind that the revised engine does have more torque.

Only ever seen power figures at the wheels, guess we'll have to wait until the 997 is placed on a chassis dyno by an owner...

So with full tank you're about 2835 lbs which in deed is very impressive.

But you know, one can take the same ~400 lbs off of 997 GT3 and then with about 2900 lbs and 415 hp & extra torque surely it will be pretty damn quick car. You're doubtful about 415 hp fiqure but trust me, the real hp in deed is that or higher.

MJSpeed

Yes indeed...
Historically Porsche has been conservative on their power figures...no reason to think it's changed.

I'm not sure how much weight can be taken out from the 997 GT3 without going with composite body parts. All my car body parts are stock.

As a reference, the 997 GT3 Cup running the Speed WC, with CF fenders, doors and hood, naked interior, no A/C, lightweight rear deck lid, BBS Mag 1-piece wheels with Toyo RA1 hits the scale at 2,800 lbs.

I might actually consider a 997 GT3 RS provided by RUF. The work they have made with the 996 GT3 Mk2 RGT was very impressive. A wide body normally aspirated, with a similar treatment could be phenomenal.

I hope the new 997 GT3 is 35Hp stronger than the 996 GT3. We will have to bring both cars to the dyno to see the difference.

I agree this is indeed strange that the street car would have more HP than the cup car. The cup car exhaust and intake is a lot less restricted but also is optimized for power, not longevity. I would love to see some actual dyno numbers for both.

Press coverage is great news. If the 08 model comes out without a sunroof. I'll happily get one!

we'll? we?
i'll take porsches engine dyno numbers over what ever you guys come up with any day.

The 2004 cup cars I have dyno'd showed about 385HP to the rear wheels when tested with the dynos which bolt to the rear hubs. What have you guys seen on street GT3 cars on those dynos?

cars are checked at porsche when they are test run, they must be within 10% of advertised power, more or less than that and they are torn down, i was told most are right on when they test them with very little variability

dark knight

to clarify my previous post, cars are not checked but each engine is checked for output at the factory

Then according to some on here that would mean that their and by assumption most 996GT3's produced more power than your cup car. Some even said that it was in the 400's! IMHO at most tracks, HP is over-rated...give me torque! If I have 380bhp's but can get to my top speed of say 175 mph in 15 seconds and you have 450bhp's but it takes you 18 seconds to get to the 175 mph mark because of gearing and/or lower torque ratings, at most tracks I'll beat you.

The gearing on the street GT3's is all wrong...who needs a top speed of 190+mph?

FabSpeed has published dyno numbers from the 996 GT3 on the DynaPack that bolts to the rear hubs (courtesy of Powertech in NJ).

A stock 996 GT3 reads 353rwhp up to 364rwhp with FabSpeed catbypass and sport mufflers. On the same dyno, the 993 reads 220-230rwhp and the '99 Carrera 2 close to 250rwhp.

On that same dyno, a 997 GT3 should read 385rwhp.

The stock gears spacing between 3rd and 6th is pretty good. The final gear is too long, that's why I went with a shorter R&P. The lowest gear I use at any of my local track is 3rd, so the shorter R&P does the work for me.

The 997 GT3 has a little bit shorter gears, but it also uses a 1" taller rear tire, so it will suffer from the gears spacing as the 996 GT3.

I thought the engines had to at least be at the advertised power and no more than 10% over? If that is true the 996 GT3 range would be 381 - 419.

I would be really pissed if my engine wasn't making the advertised power. 10% below would allow a 343 hp GT3.
