that'll be why you can't get 95 ron full boost and 98 ron low boost as your 2 performance maps then.

When I had my STI 4, the same dyno (Power Engineering) would give +/-15bhp on different days. My lowest figure on stock map was 262bhp, whilst highest was 284bhp. Remapped I got anywhere between 290 and 319bhp.

 

As said above, percentage gains are more reliable than the actual numbers. Many dyno's deliberately read high and there is some guess work involved when determining transmission losses. Climate, fuel and individual component tolerances can also make a big difference.

Well... I don't know what the stock power is on the Octavia vRS, but...

...I traded in a Saab 9-3 Aero with a 2.8t engine that was 250bhp stock and I had it at stage 1 with over 300bhp.

I can say that the Skoda feels just as bit as fast as the Saab did and is maybe faster to 100.

Also, and while the Saab was tuned, had a play with a Octavia vRS at the lights and there was not much between both cars.

This Skoda has at the very least 250bhp and I don't need no dyno to tell me that.

I have also driven a huge amount of fast and powerful cars and can evaluate where the power band is.

The 9-3 Aero 2.8t weighed over 1600kg. Power to weight ratio when tuned will have been almost identical to a 220bhp VRS, plus a 6-7 year old engine may have deteriorated a bit from new.

Typically on a Maha dyno (flywheel) they will show 240-250bhp corrected with 350-360nm, then on a Dynapak (hub/wheels) 210whp and 340-350nm.  If I can figure out how to attach an image I'll put up a graph from Maha on my vRS.

I dont think the standard vRS has 250hp as standard...a dyno might show this but the next might only show 210 as we all know.

I tend to be in agreement with Orville....the 9-5 Aero was a bit of a beast in its day but the motor was fairly old tech by todays standards....the vRS is a light car comparitively and torque rich through a large part of its usable RPMs.....a stock vRS will be as quick if not quicker than a 9-5 and will probably feel a bit quicker than it is because of its long flat torque curve.

V impressive it is...250 crank horsepower....I dont reckon.

Hopefully this link works... There is a bit of intake temperature correction on this but was done at Marlins dyno, around 1 year ago.  Marlins used to be the main dyno for the VW Cup cars, plus it is the same dyno that Superchips use.
