FI for 2017 models?
 

Is there a timeline for when turbo/supercharger kits will be available? My understanding is the ecu tuning isn't quite sorted due to ecu revisions.

Pretty hardware will be compatible with all the existing kits, it's the Calibration ID of the ECU.

I'm getting whispers that the 2017 car with its pretty new inlet manifold is different to the previous years so its possible that some SC kits may not fit

hoping to confirm this one way or another soon

The red manifold fits on 13-16 engines; its a direct bolt-on.

well thats reassuring
thanks for letting me know
has anyone dyno'd the swap to see if there's a difference?

Moto east tested it on a pre 2017 car running a big turbo and saw 15-20hp increase

Interesting! I wonder how the centrifugal setups will respond at typical boost pressures. For me the decision is between centrifugal and twin screw.

I cant imagine that those are acurate numbers. how does the 2017 only get a 5hp increase...but bolt it on a 16' or lower and you get 15-20? Doesnt make sense imo.

This wasn't an NA twin, it was a turbo build, so it isn't the same comparison.

On an N/A car it may only be worth 5hp (or less) but in the link it was a 443hp car with a big turbo! At those power levels, which is much higher airflow than the stock part was designed for, its perfectly reasonable to see 15-20hp IMO

There's an increasing body of evidence indicating that the real 2017 NA power increase is more on the order of 18-20 BHP rather than the claimed 5. More dyno runs will help tell if that's true.

This^^^

But to piggy back on that comment. The car has been rated at 205 BHP, but there have been dynos showing that the '17MY actually puts down more than 5 extra HP or TQ to the wheels than the previous years. Is there substantial proof of this, nope, but enough that it is very possible the revised car puts out more than advertised. Of course there are many more reasons for this than just the intake manifold.

Well the older FA20 was 10-15hp down on the claimed 197hp, so the new engine looks to be actually outputting the rated power now then.

The intake manifold is only part of the changes though, new mapping intake and exhaust header all play a part.

agreed
it looks like from the scanty data so far that the tune has been revised on the latest cars to be far less conservative, that coupled with the different manifolds looks to mean they now actually make what is claimed for them
whereas the earlier cars do not

Any chance you guys can swap 2017 manifold on 13-16 car and dyno it to see the results?

I dont plan on taking mine off, but if you want to send a loaner, I can probably convince CSG to do it with the boosted BRZ.

Does this mean you will be running your car NA for a while?

If the total changes made for 17 made a 5HP increase what do you hope to see from dynoing just a manifold?

I also want to see what effect the revised header has on the superchargers. I'm hoping for a mild 5-10 rwhp increase on the base kits.

Based on NA tuning results, I doubt there are any significant gains to be had with the new manifold on FI cars.

Oh well, I'm looking for an excuse to avoid changing the header. :D

If the new header still has a cat and your still planning to go FI then your better of swapping with something aftermarket with no cat.

The cat can prematurely let go and that can cause some conditions that will not be good. Like running lean

Thanks for the heads up. Is cat degradation influenced by boost levels and/or turbo vs supercharger?

boost. It will happen over time.. no matter what kind of induction you choose.

Any new developments?
