wow that stock MR2 was pretty slow, i thought they were faster than that.

ya so i got bored today and thought i'd have alittle fun and make a video, it was pretty hard to hold a camera just right while driving a stick shift car
so anyway, this isn't my cars full acceleration, but almost, when it goes all out the tires spin and hop around to much in first and shifting to second so that would have made it to shaky to record it. i'll make another one after the turbo is installed and we'll see the difference 
so what do you guys think?

Think of it in reverse. The car has more torque in the low rpms... but doesn't accelerate as fast because of the engine speed. Now... say you're accelerating till you reach peak power, then you shift and drop off of it, the engine slows down and now has to work its way back to reach peak power... however because it drops below peak power... the engine is now slower and needs speed up again with less momentum. The time you sit below peak power is about the same as the time you sit above peak power.
Point is, the reason the engine is pushed till redline is because even though there is less power there, on the upshift the rpm drop into the powerband so you maintain engine speed and start the next gear with full acceleration force. Much more efficient use of the given power. For example... when you want to pass somebody... and you happen to be cruising at 80mph in 5th gear around 4000 rpms... is it faster to punch it in 5th or downshift to 4th? This is different from engine to engine... but get on a track and test it. I don't like hearing repeats of what others say.

not really true....
if you're revving up to 6000 rpm you're still in the same gear that you just passed peak power in, unless you have a magic shifter and you jump from 2nd gear at 5000 to 3rd at 6000, you're still in 2nd when you're at 6000 rpm. the ST's (7A-FE's) power band is centered around its torque which begins relatively early around 2500rpm and falls off just before 5500rpm. HP quickly peeks up near redline at around 5600-5700rpm, and everything falls off very steeply after 6000rpm because the engine cannot breath at that speed. the head, valve size, and cams are the reason why.

i had to give it a shot myself, crappy vid since i used a camera though
didnt want to push my baby too hard, but think i can cut the time to 60 by maybe 1.5 seconds if i start with higher revs and rev a bit further so i dont have to shift to 3rd, gotta try again tomorrow
then i'm gonna give her some sweet maintenance for never letting me down
yay click me!
of course its in km/h and not mph lol

o, no my dad and I started to install the turbo kit a few weeks ago, we got the intercooler mounted, and we got the gauges and everything like that installed, and my dad didn't think we could do the rest, so i'v got mynzeyes to help me install the rest of it this next weekend!
ya i have my spare tire out, along with the back seats. some weight reduction helps

It's the same engine that's in the GT celica, so no it's not exactly a rocket. But makes for a pretty peppy stoplight to stoplight car. They are decent from a stop because of the awesome traction/launching and the low end 5sfe torque.
