For years the gold standard for intercoolers was the Secan GT2 IC. While talented folks such as Basal Skull and Tacker have fabbed their own are there any commercially available products worth pursuing these days? Not sure if the Secan is still available and if it were, it was $30K? over ten years ago?

That’s a great question!

Also, what’s the currently best intercooler with stock rear spoiler and stock MAF and manifold? Based what I’ve read, the factory stock units are extremely difficult to beat without changing the space envelope.

Fits under stock wing.

Indeed Secan IC is the gold standard and still is, the folks at Andial back then also did a good IC job for their 3.8 twin plugged 993 turbo and fits under the stock wing.

Even today the Andial IC is still unmatched for hi-per street 993tt. Nothing new out there since.

I don’t think there is anything new out there that is specifically made for our cars. What is new(ish) are the intercoolers used on the 997 GT2RS, 991 GT2RS and the new Turbo S. Those cars all have over 600 HP, so Porsche must have engineered the IC’s for that much HP. Back in 2017 I bought a pair of used 997 GT2RS intercoolers. My goal was to try and build a stock looking unit that would fit under a stock rear wing without any modifications. I built a plenum similar to the stock IC and test fitted it to the new IC’s. Because the 997 IC’s are larger than the stock unit, it leaves very little room for the end tanks. I think with a little imagination I could make it work. Other projects of mine got in the way, so that project is on the back burner. Maybe someday I will jump back on this and finish it up.

Plenum

test fitting, there is only about 1 1/2” on both sides to fit the end tanks, which is not enough room. I think the only
solution is to narrow the plenum down to give me me more space for the end tanks. This photo is with the tail removed
and turned upside down.

I do believe anodizing the whole IC helps releasing heat with and a good seal around the IC tray against the tail plays a major role in cooling off hot pressured air.

Was reading some of my old posts. Had fun making those

logging the data was fun too, except my track times were kinda slow,, I got down to about 10 faster per lap faster eventually

unless fvd has changed cores, their ic didn’t perform better than stock (I have one and did some data logging, as has others before me on this forum and one of the reasons I made my coolers now many years ago)

997 GT2 RS coolers are different to 991 gt2 rs and 991 turbos.
997 GT2 RS coolers are same as 997.2 turbo S

I’m well aware of that . My comment was that all of those Porsche intercoolers were designed and built for 600hp + cars. I just happened to use ones from a 997 GT2 RS.

please notice that 997 and 991 coolers are in different position and separated from the hot so their quality may be worse...
