Welcome to the forum Mark. welcometomyturbodies
then you can use that percentage to calculate 140hp->171.58hp at the wheels (or 192.17hp at the crank, on an Euro-style dyno with a 12% powertrain loss estimate).
I know this is an old thread thats been revitalised by saucer.
You can get difference results of different chassis dynos this would depend on how often they are calibrated. We used to have a Sun RAM XII Chassis Dyno at the College where I work but we moved workshops 6 years ago and we had no room for it so we gave it away. werd
We had DynoPlot software made by milfordmicros that plotted the results. After you reached max rpm you would just dip the clutch and let the rollers drive the transmission so it would calculate transmission drag/rolling resistance. The graph would then show calculated power at the flywheel. You can loose 25% through the transmission. Thats 15% through the gearbox and 10% through the final drive so that will be less. Obviously front wheel drive vehicles don't have an hypoid final drive.
So does Malone Tuning measure power at the road wheels or calculate engine power?
Now Stratmosphere show a 140hp TDI uprated to 170hp. Now what I can't understand is it shows
170hp - @4200rpm
177lbs/ft - @1800rpm
Mine is claimed
168bhp - 4200rpm
258lbs/ft - 1750-2500rpm
BHP is a product of engine speed against Torque so how does theirs only produce 177lbs/ft yet is has the same power?
Now there are more up and coming chip tuners as the diesel becomes more popular. Stratmosphere state that their flash can't be detected by VWs code readers. They also want you to send them your ecu to be chipped. After you have fitted it back how do you know if you've gained any power? You would have to get it dynoed before to sent it away and dynoed when it came back.
There are companies that use the plugin boxes that just plugin the loom and they don't flash the ecu.
DTUK Volkswagen Golf Vi 2.0 Tdi 170 Ps Cr for £341. There are some companies that will chip your car for a trial period say a couple of weeks. I you don't like the it will revert back to the standard chipping, if you do like it then they make it permanent.

Now I'm told from a good source that mine could easily be chipped over 200bhp but the clutch and transmission won't stand it.
