12psi on the stock motor isn't the greatest idea, and overall HP isn't what I'm looking for - it is the TORQUE that I want. Turbo kits like AVO's 5psi offering on standard 91 octane (most of us have 92 around) and zero fuel system mods puts out 230whp/197tq - which is more torque and close to your HP figure after you converted to e85, new injectors, new fuel pump, and a smaller pulley. FA20Club's kit nets even more on 5psi. 286whp/210tq.


The bottom line is there are more cost effective, scalable, and more efficient options out there. Supercharger on this motor doesn't appear to be worth the money.
...and yet there are multiple people here on FT86Club that are saying the Vortech kit pulls harder and feels stronger than multiple other turbo 86's they have driven. Hmmm...

Willing to bet you won't be getting a turbo or a supercharger :sigh:

As a mechanical engineer, hard to comprehend how do numbers lie...

lets not make this a sc vs tc discussion

:thanks:

People can be swayed in their perception through emotion, sound, even that big breakfast burrito they ate earlier in the morning.

Dynos, while not the be all end all, put down cold hard unbiased numbers.

That's what I thought to. But it's true I have to say it pulls harder. I got to ride in a frs with the P&l kit. It pulls harder then my buddy's Sti that made almost 75 lb tq then mine.

I love the output. It needs E85 to get there, but this is still on stock headers. No ECU trickery to pass emissions testing. The smooth delivery is good on the drivetrain and clutch.

I'd love to see what the output was at on pump 91, just for kicks. But I love seeing the potential is there.

Perception is part of what makes this car fun! It feels fast, because of the low limits of the tires. It's got short gearing, and the intake sound in the cabin makes this little car feel fast. I loved racing on the track. There's little doubt my previous projects were much faster, but the BRZ feels amazing on the track. It feels quick.

How many of us are going to be racing competitively? Having a car that feels fast, but isn't, will reduce speeding tickets. I know. The majority of us will take perception over reality any day. Perception is more fun anyway. :respekt:

Actually, I saw the ECU reporting the O2 System readiness as a steady "Incomplete" even after 700 miles. This would fail emissions testing.

Please elaborate. This car doesn't say "ready", even with factory cat in place?

Wow the results on E85 are nice.

Power is awesome. One question, though: What happens if you need to go on a long trip, maybe to somewhere that doesn't have e85 available? You'll have to swap the pulley to be compatible with regular gas, no? Seems like you're pretty much married to E85 at that point (unless swapping the pulley is super easy, which i have no idea of).
