2013 Subaru BRZ Long Term Road Test - New Updates

 

Toyota GT 86 chief confirms supercharged & turbocharged variants under consideration - report

 

 

might as well install a rotrex.

 

The giant peak power plots are cool and all, but I wish more companies would focus on making more torque under curve with these things. I've only seen one plot so far with a good amount of torque under curve. IT was on a fully built shop car.

*edit: I also want to see the plot to the roots type sc that Innovate was coming out with

 

Roots supercharger?

gross...

 

Dyno queens gonna dyno queen.


I want to see one with an EFR6258. 300ft-lbs@3500rpm and 400whp@7000rpm sounds like fun.

 

You'll see one soon. The youngest son of the Tuner Tools family is going to be getting on in his FRS. He's a current WPI student. And owns a 1.6 miata too.

And on the power curve, he's making more torque than the stock peak before 3500 rpm.

 

Calling that a dyno queen is a bit of an exaggeration. That has a plenty big power band for a drag/street car, and would probably do pretty well on the track too, assuming it wouldnt blow up or overheat.

There are 600 hp time attack WRXs and Evos out there ripping it up. Im sure theyre tricky to drive, but that doesnt mean theyre not fast.
Like usual, you guys are way too fixated on having useless torque at 3k rpm.


700 hp from a 2.0L engine, probably a bit peaky... still really ******* fast:

 

Looks pretty good to me. Just because torque isn't flat doesn't mean it's not making a lot under the curve.

 

Yep. At no point does it ever make less than stock, and they started the pull kinda late, in my opinion. I bet that thing ******* RIPS from pretty much any RPM you'd care about.

Unless you're all like "Hang on bro, let's race, but let's shift at 2000rpms."

 

Ok techsalvager.

 

I laffed.

 

I saw that car today on Reddit. I'd agree that for a strictly street car more torque would be nice, but you cannot deny that on a track that is a great power curve.

How well that motor would hold together on any kind of track is a whole 'nother issue though. Stock block iirc, seems like it would explode pretty quickly on a road course.

 

Well it takes ~2000rpm to get from 200ft-lbs to peak, so I'm sure it's nice smooth delivery.

But it only holds it for ~1000rpm. That isn't exactly what I would call a wide powerband.

But more importantly, I don't want 600 ******* horsepower!

 

When you're talking small displacement motors like that, though... you don't see cars making that kind of power with 4000rpm torque "plateaus." Miatas included.

I'm with ya, though... for my purposes, i'd rather see 350whp with crazy response and ginormous flat "curves."

I just find this completely insane and awesome. I REALLY want to see a pull from 2000 or 2500rpms, though.

 

No reason why you shouldn't be able to tune the boost control to keep the torque peak at say double factory, 225ft-lbs from 4200+, and then you'd love it like woah.

But if you were going to go for that target, then yeah, smaller turbo (or EFR?) would be smarter. I admit.

 

+1

I gotta laugh at all the guys whining their lightweight sports car doesn't have enough torque below 3500rpm. Sure, short shifting at part throttle is nice around town but even in my C6Z when it's go time, I drop down two or three gears. Our 95R shop car has I/H/E and ECU on a stock JDM NB2 long block. It's perfectly happy scooting around town, short shifting with sharp throttle response and still easily zipping past normal traffic. The stock FR-S I drove on track had perfectly spacd gearing for the available power and was just fine. In town it pulled smoothly enough but needed a downshift or two if you were in a hurry. Big deal.

Too many members here seem to be almost offended if it doesn't have 300lbs ft at 3000rpm I think it's an ex-street/drag racer or hot rodder mentality. Unless it boasts crazy torque down low it's not a real engine, insufficient or something. I don't get it.

 

I didn't say any of that.

I mentioned more torque under curve because it feels fantastic on the street. Part throttling at 2500 and having the car scoot up to speed effortlessly is super awesome. Just personal preference.

This isn't the race section. There is no "wrong answer" its all personal preference.

I had a 3076 on a street car, don't lump me in with the likes of Techsalvager

 

It's still gonna have that, though...
