High torque GTI

[GrayMK5GTI]

mine came up with more torque than a lamborghini aventador on the awesome dyno = dont use their dyno as it clearly is fooked, ie 400lb ft is not possible out of a ko4 on 2+, might be if running water meth?

James got 450lb ft on JKM's - that was K04 mapped to WMI

270-315 lbft is the very most you can get out of a K03  

K03 Stage 2 (Revo)................

Revo stage 1 on JKM rollers 320lb-ft

I'd better change my post Robin

....Why? - I'm plotting < ~320 ftlb on Stage 2 and Shabba is < ~320 ftlb on Stage 1 (my B/F/T settings are turned down and his are probably turned up).

265 from a stage1 on k03!?  what sort of boost is the K03 running to get that... Wow, I bet the EGT's are well high, ouch.

Oops I misread the scale

I have used dynojet dynos before and got high torque figures, it's caused by the incorrect RPM calibration. It also means mid range BHP is way out of scale.

....Am I right in thinking that it's down to the dyno operator to correctly calibrate the RPM?

That was before I fitted down pipe so was still running precat when it was on the rollers.
I was running B7 F9 T6

Haven't had it on rollers with new settings and hardware
Now B9 F9 T5

....At JKM I was, and still am, running B7 F7 T5

Whose VRS is that then, Hedge? I see it was back in 2008, so I guess it might have been 'muckipup' Dave.

It's different on different dynos, some use an inductive pickup, others use OBD data, some require the operator to input the RPM tachometer details.

If its out by just a few MPH per RPM it can massively under/over read.
