Bolt-on HP estimates?

It has pretty much been discussed that there won't be anything significant to gain, they put a lot of work to maximize the output in this engine from what's been said. Expect similar gains NA that people are able to get on the 1st gen. Rods and pistons are improved, discussed in other threads. There's not a lot of detail on the tranny, but the biggest improvement noted was the 4th gear synchro.

Just found out I have E85 at a station a couple blocks from my new place. Wonder how those curves will change with some corn in the mix...

Very unlikely. All engines nowadays are basically maximized from the factory, that's why the only real gains these days are removing emissions equipment and tuning for E85. Even with turbo cars, E85 and crank the boost.

This isn't the Fox-body Mustang days anymore, where you could take a 225hp V8 and do an intake/maf/headers and pickup 50+ hp.

I think its fair to say that with the recent dyno show just shy of 210hp, our new NA target MUST BE 250hp at the wheels without touching internals.

NA 250hp at the wheels - what a fucking SWEET number that is to actually realistically be thinking about.

I don't think that is at all realistic. Bolt-on K24A2s on E85 don't even make that kind of power even with cams..230whp on E85 seem much more possible.

We have been able to make 40hp in NA bolt on mods with e85 on the FA20.

Dont take my word for it though, there are examples in these forums.

Oh I'm not. I have been on the forum long enough and done possibly too much research. There is an unacceptable amount of variation among the dynos to draw a stable conclusion. The same setup on one dyno will net a delta of 40whp yet on another 25whp even when tuned by the same tuner.. I promise you, you aren't going to make more power than a cammed bolt-on K24A2 even with E85 and bolt-ons to a FA24.

190 whp + 40 = 230.
Sounds about right

I think if your argument is that we shouldn't believe the dyno charts provided by those on these forums over a lot of time, well that's pure speculation unless you can provide some evidence that all of these 40hp more machines were fakes.

I mean I don't think what one engine cannot do is no reason to suggest another cant.

For the K24A2 to reach 250whp you would need around 80hp increase from bolt ons and e85. I'm not surprised it doesn't.

I'm sticking to my guns.

Remember that the K24s are port injection while the GR86 is port+direct injection.

For example - Porsche was able to step down from a 2.9L port injection (255hp) to a 2.7L DI (265hp).

So apples to apples - we could assume roughly 15-20% more power just by being DI? Maybe someone’s math could be better than mine.

I would also like to add that the Toyota Racing Series are based on the OG 2013 2.0l engine released here in australia, no internals, just bolt ons and a new ECU - these produce 240hp (179kw) at the crank, up from 197hp.

Thats a gain of 43hp. I cant find the performance at the wheels, but I'd assume it was around 200hp or more.

Is it practical for the street with the noise of straight pipes? probably not, but there you go. I'd imagine there would be a little more power there if the teams were allowed tweak it (its a locked ECU).

Look at this lineup

SavageGeese's GR86 video review has a few stock dyno run's on a Dynojet. Best run was 209 whp, 175 lbs-ft. Lowest run was 206 whp.

Whatever you do, dont rush in and waste your money on bullshit. We saw a lot of that in 2012 and 2013.
