Stock FS-DE dyno

[TheMAN]

stock dyno (non-MP3)

For some reason Acrobat is being retarded, but I assume the dyno is depressing.

Nice torque, no power.

 

[Crazee D]

I guess that would be about in line with expectations.
Now the BIG question.....What IS being tested?
and ofc, what mods do u have planned....

 

[zentrandi]

why are our cars so slow... for me even with intake header midpipe stock exhaust...

 

[Kansei]

Yeah that torque curve is pretty nice. I'm always amazed that the Corolla with the Celica GTS engine has 170HP and like 125 ft. lbs. or torque (at the crank). I bet it has less torque than our FS-DE, but considering it's a 1.8 that isn't too bad.

Maybe the FS-DE just isn't a great engine and Mazda didn't feel like developing a new engine until the next model (The Mazda3). That's my guess. It doesn't feel too slow for me though, I really don't mind it. I have FS-ZE intake cam, UDP, header, CAI, and catback exhaust.

 

[zentrandi]

did the UDP make a rea difference? its the only mod i am considering left. i dont want to get out of the "stock sound" unless i go for the RB or MS exhaust.

 

[Kansei]

The UDP was actaully a noticeable difference, but at the time I had a header, CAI, and Mazdaspeed axleback.

I'd do it again, and I got it for around 120 IIRC from a GB RR Racing was doing.

 

[zentrandi]

so with my set up it would be noticeable? how was the low end? better than before?

I really don't think there's any single NA mod for this car that I could really get that specific about. All I know is that it felt a little different and I liked it. I'll hopefully by dynoing my car this spring so I'll let you know how that turns out.

 

[zentrandi]

cool, if i happen into some cash thats the next thing on the list before i go for some rims that will set me back a grand, and the oem sedan lip/skirt kit (painted) that will set me back another grand....

 

[chaosProtege]

yay for torque! when i installed my UDP the major thing i noticed was a much quicker throttle response and smoother acceleration.

 

[PR5Matt]

Looks like a single runner 626 manifold would help after all. At least smooth out the curve.

decent torque for a n/a 2.0L....

you can see that the engine just dies above about 5800...the biggest gain would probably come from opening up the breathing up there. that would help it to keep making torque at higher rpms, which is what makes real power. id' be interested to see a dyno with an intake, decent headers, and a less-restrictive exhaust. although i suspect the head itself is a big limitation as well.

that's why the celica engine makes that much power...it only makes 125 ft-lbs, but it makes that all the way up through the rev range.

Last I checked it's peak torque doesn't start at 2500RPM like it does with the FS-DE, more like around 4500-5000.

 

[Crazee D]

B-series swap...anyone? What else would be easy to find, cheaper, more abundant aftermarket performance parts. Maybe an SR 20?
Maybe less hassles with a Ztec?

Seriously tho, what "testing" was the baseline dyno being used for?

 

[Lt. Dan]

Make me wanna pick up an extra cylinder head, have some fun at the machine shop, and give it some good cams....

 

[zentrandi]

yep yep yep, and i have an auto... but i still want to tune it to the maxxx

 

[TheBryGuy]

Wow! Look at all that horsepower at my fingertips...(burnout)

 

[dmitrik4]

kansei, i didn't say it did...i stated that its torque doesn't drop off higher in the rev range like the FS's torque does. making XXX lb-ft of torque at 2500 rpm results in a lot less power than making that same torque at 5000 rpm. if the FS could keep making torque higher in the rev range, the power numbers would go up quite nicely.

i think a B-series in a 3rd gen chasis would be the best of both worlds; best engine coupled w/ the best chassis. might be a tough swap, though, and probably not street legal most places.
