When you say "dyno's" you mean rolling roads. These are full of assumptions.


Rototest shows you power to the hubs, metal-to-metal, no slippage, no friction losses.

After that, how much is transferred to the pavement is a function of tyres and surface, imho.

"997.1 TT 6 Speed, HRE's, HR sport springs" - you stole my car?

 

Hehe thanks for catching my MJ reference. And yes I do feel the same about 997.1 Turbo, once you take care of the exhaust and the suspension, it's a keeper for life. You don't trade Michael Jordan, and you don't trade the last Mezger engine in production.

I didn't realize you have the car I want; 2009 Turbo with TPC suspension! Unfortunately I am stuck with 2008 with the "classic" PCM system LOL. I don't exactly like the after-market bluetooth and ipod adapter that I have to use.

BTW, TPC Racing web site is down? Are they still in business?

 

991TT will be a dfi engine for sure...PDK trans body simplky does not fit to mezger engine block...All of us are the fanatics who care whether a porsche turbo will stand 700,800 or 900awhp with closed motor...Porsche simply doesnt care about that...we represent only around 1% of total 911TT sales...so they wont miss much without us...for almost everyone 550hp are more than fine to live with...and when pdk chimes in to play...who cares about more power...Porsche made GT2rs to end mezger engine production in an amazing limited edition car...I am sure there wont be any other mezger 911 in the future...

 

Thanks. I do have it in higher resolution (this was taken with my Canon 1D, native 2500 pixel across); let me look.

Here is another shot, taken in the switchback near my house. This is partly the reason for all my posts for stiffening the suspension .

 

Good question about TPC...maybe someone close to their shop can chime in. Clicking on their sponsor link used to get you to their product store, but now it just takes you to a general page without a store front. I wonder if their business model changed, or if they are in the process of redesigning their store??

Don't let me change the topic of this thread...but just real quick: I had a chance to run a PCA sponsored time trial event, which was the first time trying out the new suspension setup off the streets. Wow, comparing to my stock suspension last year, this felt very planted and flat through the corners. I'm a novice, but I couldn't feel any body roll, and I was very happy with how the car didn't show significant signs of under OR over steer ( I know that comes down to the specific setup, but kudos to my experienced installer who got it right).

Can, I agree with your point that these are cars to keep. Who knows what resale value will do in the future (mileage will always bring it down), but they represent a vanishing era of dry-sump, 6-speed, mod-able cars! On a long enough time scale, it will need to be a matter of "adding" to the collection rather than "replacing" for another.

 

Not to get too off-topic but it will be interesting to see if the 991 GT3 will have the Mezger considering it has recently been photographed with the PDK.

 

997.2 has stiffer springs and front sway bar, and PASM is revised such that the PASM Sport setting is much better (much more compliant) than 997.1. It is an improvement and if you are not going to mod the suspension, no doubt that 997.2 suspension is more desireable.

That said, the change is not that significant and for me 997.2 is *still* too soft, and still has a lot of body roll. It doesn't feel sporty and tight enough, like what one might expect from a world class sports car (no body's fault; Porsche intends for it to be that way).

A 997.1 with Bilstein coilover is a lot more precise and fun than a 997.2 in stock form. Essentially, a good coilover like Bilstein (which also makes the OEM Porsche suspension - same designers, same engineers, even same consultant (WR)) is the great equalizer that will bring your 997.1 Turbo to un-equalled, top-notch status, for daily drivers.

 

Why would it EVER have a Mezger engine, when
1) previous GT3RS had 3.8 DFI engine,
2) it is already known that 991GT3 will have 3.8 engine

Mezger are expensive, "dirty" and non-economical. They are history forever. Enjoy them while they still exist in older cars.

 

997 GT3 and GT3RS do not have DFI engine - they have the GT1 Mezger engine.

 

My mistake, I apologize, just now read on one page that 3.8 in GT3 is GT1 derivative. I assumed GT1 blocks were all 3.6.

Is there any more information on the 3.8 engine in GT3 that I can read, please?

 

Where are you getting DIRTY? Go ahead and post up your carbon numbers and how bad they are..... My gosh man

 

I've got to say thanks for all the good info, particularly @Cannaga for the suspension explanation @Peskarik for the interesting Porsche Owners metrics (that I really, really don't fit into).

I get that the PDK is quick and the new best thing but I'm just not interested. My GF got me a couple of driving packages in Vegas and New York and while I really enjoyed driving the lambos and the amazing 458 flappy-paddles just aren't for me.

 

as a man who used to own a 427 quad barrel straight pipe setup I say the dirtier the better. if you want clean get a volt, my 997 is already too quiet and too damn clean as it is, I'm looking for more ways to make it louder and dirtier with lower mpgs

 

+1000

 

+1000000. I dont get the reaching to insist a .2 is better because its newer. Its Dirty it has dynamic mounts.... what next the plastic is shinier? Or the fill cap is metal vs plastic???
Oh and it shouldnt need an engineer to figure out that if one engine can take high HP and another has issues which one will be stronger long run
