Possible good news thought - ra/2019+ has 400 to the crank stock?
Given the data in the link in my original post, stock 2019's seem to put to the wheels about 270-280hp. Call it 275.
Stock. That is of course a function of the dyno - but what does that mean is at the wheels? Is there a 30% loss? 310hp (public spec) suggests only a 10% loss...I don't think that is possible across an AWD system, even one as good as the STI's. Sort of like the 22b having 279hp.....um, right. (Thank you SUBARU!!!) I suspect it is about 30%. (please comment) Does that mean that at the crank the stock car (2019) is making about 400 hp? That is actually pretty impressive to me at least. With a warranty. The post RA ej257 may be the best one to get and (perhaps) a long term gem....no DI issues with carbon....something I worry about if they don't mix port injection into the new FA sti ..., and if left stock these cars are quite reliable. It sort of would make sense that Subaru would pick a number they feel is top of the reliable for 99.9% of cars to sell to avoid warranty costs/exposure. Does that seem reasonable? Sort of makes one think happy thoughts during the fun times.... jcb PS: the 2015's seem to be about 245 to the wheels....so about 350 at the crank. Quote:

^^ it seems like **** tuning in first and second gear might be to blame. Savageese talks about how the terrible tuning kills power in 1st and 2nd but magically pulls hard in 3rd. He mentions it in his series.white sti review.
Of course, someone will nonsensically mention the heavier wheels, but that’s not going to cause a roughly .5 second increase in 0-60 and 5-60 rolling. |

I have 18" forged wheels and michelins......about 9 lbs down per corner.
Savageese makes sense. Perhaps they don't want things to break.... Then 3rd is a train. So, let's just say the given numbers are correct from the above video: 295hp/305 ft lbs at the wheels....if "only" a 20% loss that means 368hp/381 ft lbs. AMAZING, thank you Subaru.
