Eric,
You'll love the instant on with the supercharger ... it's totally addictive and the sound even with stock exhaust adds to the enjoyment. Keeping your foot out of the bottom of the loud pedal is hard. Can't wait for spring.

Guys,
Before you all run out and spend your hard earned money. Give me until March-April to let you know how this TPC setup reacts in track mode. I plan to cut weight down to 2750 lbs and run some time trial and hot lap events late March and early April. My concern is heat soak after 5 or so hard laps. I haven't met or heard of anyone really running hard with this setup on the track. All I know of is a few people who run HPDE events.

Since, TPC would not upgrade my unichip set for the intercooler, I bought an Innovate wideband and ended up using a single injector one size larger than the injector that came with the unichip. Initially TPC would not give me specs on the injector and only stated that it was a "Porsche motorsport injector".
I found that it was a common $60 72lb injector and could easily be upgraded to a larger size based on your fuel needs.
Since last spring, I have put 6k miles on the setup without any issues. The whole package cost me $400 including the new injector. The intercooler is a used spearco core that I bought on ebay for $50.
Anyway, that intercoooler looks a lot like the ones in my S4. Might a little cheaper, since they use 2 & people upgrade them all that time.

I don't believe an air to air intercooler sized to fit in the engine bay is suffice for track duty. This is the reason why the liquid was used. A friend of mine who races a supercharged mini upgraded to a Liquid IC because of heat soak after 5 or so laps. I am sure an air to air setup is adequate for day to day driving and a few blasts up and down the highway, but will not be adequate under constant boost levels. I don't speak from experience yet, but I will hopefully have some real life experiences to report to the forum in the spring.

Good Luck what ever one you do.

I also did not have the wing.... However with the extreme make over (new roof and rain gutter delete amoung other work) I am adding the NB turbo wing and front/rear bumper skins. Not sure if I will do an intercooler as it hides the engine. I have not had any heat issues on the street.

The air to air is more resistant to heat soak so long as capacity and flow are optimal. The air to liquid will alway have a ceiling since the captive liquid used can only soak up so much heat before there is no more capacity - each lap will heat the liquid higher and higher until there is no more temperature delta.

Correct me if I'm wrong, but the factory put 2 nice big IC's back there & the 993TT's are not to prone to heat soak on the track, & 2 turbo's produce much more compressed air heat then a low boost SC.

Maybe we can take our headlight washer nozzles and move them to squirt the a/w intercooler.

Absolutely not! I will remove the SC, if I dont purchase something to cool ambient air before track season. I am having difficulty understanding how an undersized air to air intercooler would fair better than a liquid ic with a radiator constantly circulating lower temp water through system. More research on this topic is in order as there are mixed opinions on this.

I don't follow. The TPC a/w intercooler has a front-mounted radiator for the water to cool. So it's indeed getting some cooling. Unfortunately, they mount it right behind the passenger-side oil cooler, which seems far from optimal (and on it's face, illogical). But still, assuming the radiator is properly sized, it should run fine steady-state I'd think.
