im talking about any new mods. I already have most of the stuff, have some one work on fuel limitations, I see .1 with 1000 hp, 991 with over 700 and we .2 owners barely on the 600 .

With regard to market prices, I have seen the manuals actually come down (in general) since the new manual offerings offered by Porsche. But the overall market price increase of 997.2 TT and TTS has been crazy to me.

Several of the mods for the 991 work or can be modified to work with the 997.2. I’m sure you have seen several 9 second 1/4 997.2 cars recently thanks to ES Motor. But be prepared to add meth if you haven’t already.

Fairly minor differences, but one big one. The high pressure fuel pump is the smallest on the 997.2 of all the turbo 9A1s. Results in needing meth as a fueling band aid for anything basically more than flash and exhaust.
The HPFP is the largest on the 991.2 turbo S and is supposedly sufficiently large enough to be capable of full E85. We will find out. The larger fuel pumps of the 991s cannot be retrofitted from what I’ve read.

Too bad it can't be retrofitted. Although I'd imagine the parts themselves would be very expensive to get from Porsche.

I have kline exhaust, headers, tune, awe intercoolers, upgraded turbos by SAM, BMC filter, meth.IPD Plenum, Ypipe on dyno could not get into the 600hp. I also tried to upgrade my fuel pump but it resulted in a disaster so im stock and seen every other platform still moving up.. my main goal is to participate in half mile events and get a 170mph car.. last time I did 166- 167.8...I had numerous boost leaks and disapointments, but is all part of the fun

Unfortunately as you've found out the fuelling is the limiting factor on the 997.2 not the turbos so sadly your uprated turbos are not helpng you at all.
You'd be a lot better off calling ESMotor imo, their ES600 package gives 600bhp with just a catless exhaust and a map. I've also seen a stock car ESMotor mapped with 580bhp so with your bolts ons you should be 700+ easily...

I work in the performance aftermarket fuel systems industry. There is help/options for the 997.2. They just need to be developed a little bit...
1. upgraded in-tank or in-line pumps. When you increase the flow and pressure feeding the cam driven HPFP, fueling limitations can be overcome. This a popular upgrade path for BMW M4's and Vette C7's.
2. upgraded HPFP. There are options. I work closely with Uwe (former bosch motorsport engineer) at Xtreme DI. We have developed fueling kits (our injectors and his pumps) for ecoboost applications. This man is a genius and I am fairly certain he could develop a HPFP for the 997.2 or engineer a way to adapt the 991 pumps to a 997.2.
3. port manifold kits. Dual-injection systems (GDI + port injection) are popular on the latest models of DI cars (many VAG models, 2018 mustang, among others). These are expensive and can be clunky + difficult to tune, but they completely solve the fueling limitations.
Lack of fueling is definitely a significant hurdle on the 997.2. But ther is hope. It is only a matter of time before we make some break throughs.
