Agreed. A friend of mine was part of the 335 craze. His 335is was tuned to **** and pulled a ton of power on E85, but he had CELs every other week and eventually had to have the turbo and his fuel pump replaced.
Not worth it, but we'll surely be seeing them on the streets.

The Fuel pump was a major problem with those cars, even the stock ones.

So is this shop pretty much the only competition in town for 991.2 chip upgrades and hardware? I was figuring the Flaps is just the loud button like on the GT3s or am I just miles apart in this situation?
Also if the tuners are upping the dosage unit (boost) that they might want to start going with stronger head bolts. I don't know what the new engine is capable of, and if anyone has experience with them or not or `em I just a little paranoid. One would think that aftet the GT3 stop sale that Porsche would go on the side of using stronger bolts since they are building cars with turbos... The first thing the tuners and shops would do is increase forced i duction.

The 991.2 engine isn't new. It's the 9A1 with turbos. Check PeteVb's technical analysis on the engines. The 9A1 internals were highly over engineered to handle the turbo power that was to come. Most of the internals are the same. Porsche won't develop engines for every model refresh or make new engines. The 9A1 is very highly modular and was designed to miminmize cost for all 911 and 718 / Boxter / Cayman platforms. Pete's analysis is excellent. He's an engineer with huge amounts of knowledge in engines and racing dyinamics.

This is nonsense and if you read the article/interview in Panorama from a few months back with the Porsche engineer you'd realize this. Yes it's a flat six that generally looks similar, but it is a totally new engine, sharing almost zero parts from the 9A1. Yes, having learned a lot building these engines over decades, I trust Porsche got it right, but stating it's just the 9A1 with turbos slapped on is totally wrong. It's a similar design, but a totally new motor.

You can trust your journalists and I can trust Petevb who I know from the GT forums, and who has done huge services for the tracking community here.

What's nonsense is your reply to my post and your continued denial of facts regarding the 9A1 and 9A2 engine. You like drinking media KoolAid? Fine. It's nothing new at all. In Pete's first post in the thread he says "The 9A2 is clearly a close derivative of the modular 9A1 family that powers the current 981s and 991s. Visually it appears to share most components and castings, with the turbo plumbing bolted on after the fact…"

I'm not referencing a journalist. I'm referencing Porsche's head of development for the boxer engines, Thomas Bradl, who states "The 9A2 engines are virtually completely new." And then goes on to explain how basically every component in the motor is new, not just in design but also in manufacture. The 9A1 and 9A2 motors are entirely different engines, regardless of how similar their designs might be.

Except it doesn't. Visually they look the same and they're generally a similar design, but in reality they are not the same motor at all. You're reading way to much into one sentence of Pete's comments.

Don't believe everything you read from Porsche.

i don't disagree, but it brings up another interesting point. while i don't think i'd ever "chip" a 991.2 (impressive numbers i might add), one might say that the 991.1 is fast enough....yes? no need to push the envelope? tell that to the guys who
-install plenums
-install fancy air filter contraptions
-install fancy air induction/intake systems
-install an even more open aftermarket exhaust kit
all in an attempt of wanting to produce more power and speed. is the 991.2 "fast enough as it is"? for some i'm sure, for others, maybe not so much.

Resistance isn't overcome by just added hp and engineers have sort of reached a plateau in regards to passenger vehicle design. Today's cars are pretty well matched to the competition even with 200 +hp deficits. Hp is a bit overrated and breaking the laws of physics is going to require radical changes in design going foward.
Just don't want people to believe that a reflash of there ecu is going to drastically change the dynamics of there cars.

I have realized that cars in general really don't perform linear to there hp increase. So a 400 hp car isn't half as slow as a 800 hp car. There seems to be a plateau that when reached it takes that much more to overcome.

It really depends on the person, their enthusiast level, their life, etc. I myself swore that I'd never drive a stock car for as long as I lived, and my old Mustang was heavily modified (tastefully, though ).
Now? I'm completely the opposite. I enjoy my GTS so much, and I force myself to keep it stock(ish). I swear that I went through a phase of depression when I purchased the AWE SwitchPath, as I was pretty pissed off at myself for modding her.
