Matt's MY2013 BRZ Thread

why is there such a dip in the factory torque curve? did they try and do that stupid thing where they lean it out for emissions purposes, much like they did on the 2007 STi's?

 

I went for a test drive in this car... talk about instant power :clap: but i think I still like the explosive feel of the turbo

 

it's not causing the motor to run lean, is it? Is that....safe?

 

no it's actually causing the motor to run rich for about 4 power strokes. at WOT the BRZ's port injection and direct injection are shooting simultaneously into the combustion chamber. causing the system to read rich until air flow catch's back up. The dip in the graph is the blurp from the MAF basically saying uhhh?? need more air?? HELP!!:rofl: not to mention the injectors in the intake are coating the back of the valves. That's partly why these cars with a SC or turbo with low boost make great power. extra gas just needs that extra air.

 

It's NA....and not running lean. VERY FAT from the factory.

 

it's only one pipe!.. fail :thumbsdow I don't think BRZ's look good with only one pipe.. my opinion doesn't matter though.. it's your car. for some reason I think one exhaust pipe makes the car look off.

 

How obnoxious is the exhaust?

 

i'll be happy to see it with dual tips again :clap: I don't know why but every time I see your car I want a BRZ.. I wish I had/made more money :|

 

What setup did you go with your nameless. I love mine, ended up going with 4"mufflers, no resonator, 4" tips even the wife likes it

 

Ah, you should have. I want to hear it before you reinstall your other exhaust.

 

Looking forward to seeing these on the brz! Nice choice.

 

Love the RPF1....what size are they?

 

Nice Matt! Those wheels look good on any car! What tire/size are you mounting to it?

 

Careful....Matt 'can' ban ya.

 

Congrats on the new wheels Matt! Can't wait to see them on the car.

What kind of rubber are you running?

 

Nice. I have some 17x9 in SBC I'm waiting to put on the car. For some reason all of the supplied Enkei valve steams are leaking though. Weirdest thing I've seen.

 

Looks great! Don't think it really needs springs, looks good as it is now.

 

Please lower that off road vehicle ASAP!

 

Wheels look awesome. Springs.

 

Looks awesome Matt!

 

Meh.....it needs MOAR forced induction.

Looks good but yeah I agree at least the front needs lowering a little

 

That thing looks great! Just swapped my WRX out for one today.

 

That looks fantastic Matt! I got the Eibach Pro Springs for mine, and I'll be going for Enkeis in the coming months. I'll likely copy your size / fitment. I'll have to decide between the Conti's and the Pilot SS. I like the Gold and White

 

How are you liking the Conti's. That is the tire I have considered to replace the stockers.

 

Loved them on the mini

 

wow thats a clean brz.

 

I have definitely seen more tq dip in other brz dyno graphs.... I guess your mods some how made it less of a dip?

 

Looks like a Honda graph.

 

His tq looks very close to yours and beating ya in many rev bands. I think a stock Si will outrun a BRZ....until some good twisties are involved (maybe).

But when I drove my co-workers I liked how responsive his BRZ was...250ish (bolt on SC kit) would be perfect.

 

Looks sweet!
