"Not Goldilocks, just hot" - love that! "Not smooth on rough road" - no surprise. "Loud wheels and trans" - no surprise. "Hard to get out off those Sport Buckets" - no surprise. "Pulls better than a Carrera S at speeds due to forced air intake" and has the effect of "increasing HP by 10" - that is a surpise, wow!

Yep, someone on P9 predicted it might be too harsh for some. This is not a Turbo S, it is a track ready GT car. A SA once told me that most 997 GT3 cars were resold many times because buyers liked the "idea" of driving a track car, but in reality didn't like the harsher driving.

As a weekend and track car, I will like the sportier, more visceral driving characteristics. 2 issues to accept: I will not love the manual over the PDK, and I will not like the low front end clearance. But, I plan to modify the black plastic spoiler to make it removeable to give it better city driving clearance.

with all due respect to those who feel differently, the side scoops look even more akward/wrong in the lighter coloured cars shown here (especially the white and silver)
I must agree with you that I really prefer the clean lines of my Sapphire Blue GTS.....I don't really like the side scoops on the GT4.......BUT, if the 10% increase in hp comes from those scoops.....that is sure to be the cheapest power mod add on the Cayman has ever seen and I'll be looking at slapping them onto my car:)

+1 and without the GT4 marking please :)

A perspective (and price :mad:) for the GT4 down under... Porsche Cayman GT4 first drive review

"Pulls better than a Carrera S at speeds due to forced air intake" and has the effect of "increasing HP by 10%.
That statement is so full of BS. By implication that would mean that the 3.8 would be a minimal hp increase over the GTSs 3.4 - equivalent to the 991 3.4 - without those. And NO, I don't take that to mean that its equivalent to a 991 3.8 with the X51.

Has that journalist smoked medical MJ prior to writing this or did they just want to insure their invite to the next shinding.

Ram air would only increase the power output at high speed (at speeds where the car is pushing significantly pressurized air such that the air entering the ram air intakes is significantly above atmospheric pressure - similar to turbo concept but far lower psi likely).

So at standstill (ie a dynamometer) yes the 3.8 still produces far more hp than the 3.4 you reference but the additional "10%" would only come into play at high speed. Whether it's actually 10% and at what speeds is TBD

I'm SO confused! Is the 385 horsepower Porsche claims taken on a stationary dyno, or do they possess some magic way of rating the hp while at speed? If this poorly written article is to be understood, the forced air from the intake would be adding 38.5 hp to the 385, meaning at speed it has 423.5 hp. :dance:

I guess I need a larger glass of Porsche Kool-Aid.

Does this help:


Standing in the workshop again, looking at the yellow racing hero one more time, Preuninger follows my gaze and provides impromptu commentary on the details. “The side blades are not a cosmetic feature. They ensure that the air has a higher flow rate when it enters the injection tract—to cover the engine’s greater need for air.”

It appears that the front spoiler/lip continues back to the wheel well, then up to just about to the side indicator lights. Could be multiple pieces, but if it isn't your notion won't be easy. Also, i don't think you'll be hearing "hey, lip spoilers are cheap" much in regards to the GT4.

I wouldn’t overthink anything in that article. It also says the GT4 front end was taken from the GT3. And if you read the comments, an earlier version of the article appears to have claimed the GT4 engine was based on the GT3 engine...

I thought I read somewhere that ram air is 99% market and 1% legit because it might net 1% more power. Per wiki. When I read the 10%, I thought he was being sarcatic and making fun of them.

Ram-air intake - Wikipedia, the free encyclopedia

"At low speeds (subsonic speeds) increases in static pressure are however limited to a few percent."

Yes, if you do the compressible flow calcs ram air at anything less than Mach 0.3 is almost negligible. The scoops aren't for compressing flow as much as they are just to try and capture adequate air and prevent the pressure loss that may occur at that area of the car at speed.

30+ HP from side scoops? Are there magical fairy's hiding in the scoops exhaling nitrous oxide?
