VW's 1.8T kick *** torque curve ?

[spitz7985]

I was reading up a little on different companies motors, because I really only know Nissan, maybe a Toyota engine code here and there, but not much. Anyway, I came across VW's 1.8T, which I did not particularly have a lot of respect for. Then I read the specs and the 180hp model pushes out 174 ft lbs@1950-5000 rpm!!!!! Holy ****. How does such a tiny gasoline motor make such a kick *** torque curve! I posted on vwvortex forums and didn't really get any in depth answers. Small turbo, long stroke in relation to the bore (I think it was 81x86.5), 5 valves/cyl, 9.5:1 compression and "short" cams. Nothing there seems particularly out of the ordinary. What do you guys think?

its a nice motor, but i've heard it had some problems in build quality. but yeah, thats an amazing torque curve. thats on par with a SBC. with a chip and an intake, the power is like 195, but the torque specs are like 240ft/lbs.

on a side note, has anyone seen the BiMoto? that twin engine (1.8T) Audi TT coupe? they had it on tuner vision before it got the boot and it was really bad ***. something like 400hp from each motor or something. lemme look for it.

EDIT: here it is. twin 1.8T engines making 430ps each and 570n/m of torqure:eek: http://www.mtm-online.de/press...7.pdf

I have a video of the MTM BiMoto TT. Sounds unreal at full whack.

that’s nothing....my Audi does 258ft lbs @ 1850 RPM all the way threw (stock) same 5 valves/cyl, 9.5:1 compression

The only thing is that variable intake geometry and variable lift and timing only kicks in after 5000 rpm, you can actually feel it the car all the sudden lunches forward, (as would a turbo kick in).

any specific reasons? if you throw a tiny turbo on a KA are you going to see a torque peak so low? my guess is not.

It's a tiny, well designed turbo, basically. My bro's 1.8T A4 has that same crazy power curve. Everything is availible at something like 1500 rpm, which is nearly half the RPMs my SR20DE needs to get going... it hurts.
