Meth does some pretty amazing things on this platform as we all know. There can be many issues (some catastrophic) with meth, however. I have been running it for years on a few different platforms and learned that the system needs to be much more robust than what is supplied in the over-the-counter kits from a reliability and safety perspective. My 997.2 Turbo S kit was simply amazing, designed by a vendor here - Thomas Emmanuele of Emmanuele Design. Thomas is a former GIAC tech and he also employs a Porsche tech named Marcel who does a lot of custom aftermarket work.


So goal #1 was safety and reliability. But there was also another goal with this install. Since I've kept my 991 completely stock looking - not even changing the amber side markers - I wanted it to be completely hidden from any view, whether inside the car, outside or even looking in the trunk! How would this be possible? Not sure but I gave the task to Thomas and Marcel with those goals in mind.


What came back was nothing short of spectacular. Given the constraints imposed by the need for stealth, and also to be able to fit a 5 gal pail of race gas in the trunk, parts were all custom ordered including the tall+narrow 3 gallon bladdered fuel cell, the thin AEM meth controller to fit perfectly in the arm rest, and of course all steel braided lines and aircraft fittings.


The AEM controller works similar to my old Coolingmist controller for my 997.2. Start boost for meth onset and max boost for 100% meth flow. Thomas used dual 630cc nozzles which are fine for now although who knows I may go with bigger nozzles later. Like with my 997.2, I'm not tuned for meth so no need to go with a complex system like Aquamist. The Porsche ECU compensates very quickly for changes in fuel trim so a less-sophisticated system works just fine. The AEM controller also has a priming mechanism that the Coolingmist controller didn't have. Pushing the priming button opens the solenoid (you can hear it click) and then it pumps meth into the Y pipe. I know that it's working as priming the system at idle causes idle to fluctuate a little.


There are some limitations for now such as no low fuel light but I will have that addressed shortly.


I wanted to again thanks Thomas and Marcel for an amazing custom job.

Wow..impressive...could you evaluate the net benefit of adding meth in 1/4 mile MPH ?

 

Good question. It can be significant if you are tuning for it. I know BBI and ES Motors have some success with doing that. I'm not tuning for it so my gains will likely be less.


I have no data for this car, but I do for my 997.2. With GIAC tune, Champion intercoolers, BBI 200 cel exhaust, IPD Y pipe and plenum it did consistent 135's at Famoso (Bakersfield, CA) in the winter of 2015 on a cool 60 degree day. Adding meth it did 138.9 (only got one run) at Fontana in late Spring of this year. Fontana runs uphill instead of downhill, runs at 1,200 feet elevation (vs 600 ft) and was also 80+ degrees. Pretty sure it would have went 139's or even 140 at Famoso on an equivalent day. So 4-5 mph is my guess on the 997.2.

 

That's pretty impressive..4-5 mph. On another note I notice you run light weight wheels...do you run a Nicad also ?

 

Well that is a great high-quality install

 

Thomas really does it clean, top notch install congrats

 

Oh yeah good point. The GMG LMS forged monoblock on the 997.2 were very light and probably did also contribute to the faster 1/4 mile trap. So yeah light weight wheels AND meth 4-5mph gain. Fortunately those were the only changes. How much attributable to each? Haha no idea.

 

Nice install Adam.

 

Thx gents. Cheers.

 

Wow that's clean.
