now im even more reassured that silver with black wheels is the way to go

14% drive train losses huh? That's pretty good, but I bet a bit optimistic...

Then again, they may have underrated the motor too...

Be interesting to see what the auto puts down -- with full lock up, drive train losses should be equivalent (it is on the 370Z).

172whp would be pretty good -
my S14 SR20DET got 165whp (212hp on the crank)

Well, all I know is, if those numbers are reliable, given my own power:weight goals for the car (assuming I end up buying one, which I probably will), I will want to add another 70+ whp (a 40%+ gain).

Do-able if they keep to their alleged plan of releasing either a SC'd version or kit...

I was expecting it to put down 160 at best, so that's 10-12 less whp I'd have to chase after :-p

love it love it love. 170 from the factory in a super light car. like harinjo i've been expecting 160whp from this thing this is great news. i bet a 200whp is easily obtained. i just hope we can some more torque out of this guy.

edit: arent japanese emisison regulations less strict than the US? and don't they have better gas then the US? if so i am willing to bet the scion will put 155-160 down

Its actually 170 whp in our measurements which is 15% like I anticipated. Where is the torque?

Did anybody notice the blinking engine light?

open deck isnt always that bad. the 2AZ-FE is an open deck and people have made over 1000hp with it.

I look forward to the day we ditch the engine lights all together and just show the error code/description on an LCD read out.

Taniguchis back? badass

hmmm open deck......

may need to reevaluate my plans slightly.

I was hoping for semi-closed originally.wasnt plan on doing some sleeving.

Not too shabby, should be able to get close to 200 whp with bolt ons.

awesome video, thanks for the up !!

Wow, this is really awesome!!:burnrubber:

Yeah its open deck but this engine was not meant to be turbo charged anyways right?

Also is not the JDM 86 quoted at 197HP and the NA FR-S at 200HP?

Isn't the US version supposed to have +3hp(full 200hp, not 200PS) due to less restrictive exhaust? In that case, US dynos may end up even higher. :party0030:

im still more interested in the TQ curve than peak hp

I don't know why people are whining so much about open deck. I think there are some cooling advantages. Besides we aren't really talking about a lot of power. I have an open deck ej205 (built) that puts down a reliable 330 whp for the last few years. That block can handle much more than that.

I was expecting more like 160whp so this is good news


Nooo open deck. Darton sleeves if I do end up chasing big power I guess.

Don't think it will be a problem tho I am only aimming for 200-220 to the wheels since I got other stuff that my money will be going too

Modification of Boxer 4
 

Good luck with getting more horsepower out of this engine without turbo charging it. I have owned 25 Subaru's with 1.8- 2.5 N/A and Turbo Boxer engines, and increasing horsepower and torque, other than turbocharging, is not easy to do. Most think by putting exhaust and cold air intake system that this will achieve the performance you want. With most engines it might be the case, but not with the Boxer N/A engine. This is the same engine type, that is now found in the new Impreza 2012, which puts out only 148 hp, and about 145 torque. Subaru has worked on this engine, to achieve 170 hp and about 152 torque, so other than turbo, or supercharging this engine, I wouldn't suspect to much more left, without expensive engine modification. Also most N/A Boxer engines stock will only allow you do achieve more hp and torque with low Turbo PSI 4-6, more than that, the internals will not last. I have heard that Subaru expects to a Turbo for the BRZ, but haven't heard anything for the FR-S. But your typical bolt ons don't respond the same way as with other 4 cylinder engines.

x2

Either some of the measurements are going well over stock redline (8000rpms+) or the numbers given by Toyota (200ps@7000rpms, 151lb-ft@6600rpms) simply don´t match at all with the dyno results. I`m guessing the first option is correct.
Also, there is quite a bit of dispersion on those different meassurements, some showing as low as 150whp.

Very nice. I was expecting 160 also.

Welp its certainly low on power. Doesn't look like the motor is underrated. Certainly hope this motor has some breathing room.

What were you expecting? 200hp with 170hp to the wheels is pretty darn good.

In the video they shifted at 7800 rpm. I don't really understand what you are ranting about. I think higher reading dynos will clock this in at 170, and lower ones at 160. Nothing below that. How can you expect to lose 50hp to the wheels? That's a ridiculous amount of power loss.

I mean it is what I expected. 170 is acceptable, 180 would have been impressive.

Wow that's weak. NA cars dont respond well to bolt ons. My wife's Camry has more whp.

Looks like the hp/weight will be similar to my NA Miata which is no drag queen but can get my 215 star specs sideways at will around corners. This car will be a great replacement just with a warranty!

:dnftt:

Anyone notice the nifty shift-sound indicator? that's AWESOME! :D toyota's paying attention to the details!

He's right, if his wife has the v6 camry it will smoke this thing. This car won't be fast by any measure...

Actually, that feature has been standard since the 2001(GDB) WRX STi.

i don't mind open deck there are some perks, but im just a bit surprised! especially considering vs your open deck ej205.

-the FA20 has 12.5c/r vs your 8.1c/r. (less volumetric pressure on cylinder walls)
-D4-S which naturally runs leaner and combustion temps are much hotter
-86x86 vs 92x75 (RPM vibrations)

big thing i was worried about was long term wear and fatigue without additional the structuring. i was expecting semi-closed deck. not a fully closed deck.


FB not same structure as FA
lurk more

Tq=Hp*RPM/5252

They show the Horsepower curve, you can figure out the tq from there if you need to so badly.

formula for peak tq..not same as looking at tq graph.

Did anyone notice the size of the intake and exhaust ports? That alone tells me the head should be capable of flowing well.
