Oh god dont say that. So much time and money has been wasted on trying to improve the " bottleneck " that sits on top of the fa20

Well GRMN seemed to think it was and made one. Or are we ignoring that one?lol

The GRMN manifold could be fitted in the engine bay with the original hood. No need to increase the height for the manifold.

I was thinking a 2 or 3-stage manifold with butterfly valves in it. BMW had been doing that for decades in NA motors, the 3stage manifold gives the 215hp N52 engine a 40hp bump.

I wasnt saying it couldn't...I was responding to the sarcasm of the "bottleneck" comment.

Theres little to be gained from an intake manifold change but people still believe in the loch ness monster. 2 litre motor. Boost it or leave it alone

Ah ok got you. Yeah there isn't much to be gained from a "better" manifold. There is a nice video with a guy on a race track trying to pass an ordinary 86. Even on the long straight part his GRMN 86 was even. At the end he was entirely frustrated and he was hitting the steering wheel. Gazoo did some nice things on this car, but not on the motor performance side.

Thats a bit anecdotal. Did they both have a wing and the same tires? Did they both have a tune or competely show room stock? Not much to go off of... Also no one here has a GRMN 86 so whose to say what they did or didnt do. Maybe a the few owners over seas on IG know but no one here.

I am not directing this at you in particular. However we have a lot of people here who cant see past the typical cookie cutter mod list because the "forum said so". Yet have a negative opinion on new ideas while never trying anything out the box themselves. Sitting around and talking versus doing I suppose.

I've just been lurking here in the background for years, but on Friday I got a call from a company called LW Research. They're based in Encino, CA and they help a lot of automotive companies out here in Southern California put together test/design feedback studies.

There was a study this weekend in Anaheim and they were calling local BRZ owners to take part in a paid 2hr meeting on the topic of next generation design direction for Subaru.

Unfortunately, I couldn't free up my schedule to make it, but I'm sure some in this community did and hopefully they can chime in. I did ask the person who contacted me if this was indeed a preview for the next generation of the BRZ and they said, yeah most likely.

With the recent leaks of the GR86 and Subaru ending production of the BRZ, I think we'll see some leaks of the next-gen BRZ pretty soon.

Doesn’t matter, multi stage runner lengths work on any ICE. It’s like having power blocks at low rpm, a normal manifold in the mid range, and ITBs in the upper range.

It works on rotaries too, the RX8 uses them.

Are you referring to this video?

Because if so, not really a realistic comparison. All the vehicles in that race are modified, to an extent that we don’t entirely know. Additionally, the GRMN driver is diving in early, early apexing on some corners, missing them entirely on others, and running a fairly inconsistent line compared to the car he’s chasing.

I wouldn’t really use that example to gauge the performance between a standard 86 and a GRMN.

The video is the following. The car in front is a Gazoo spec 86/BRZ which is stock and has a sealed engine cause of regulations. Driver is frustrated in the end with no luck and no power.

If an intake manifold could make a real difference we would have it already. If not by factory, then by a tuner the same way we have for exhaust manifolds (headers).
