Sorry I don't post much but do trawl the site often, I had my mk 1 put on a rolling road last weekend as it seemed , well not a GTI power wise. ANyway it started off at 84hp, after a bit of adjustment and several runs they guys managed 95.2 hp with 108lb/ft torrque. now i know this is quite a bit down on original figures, the car has done 169000 miles. it is also run on normal unleaded, the guy suggested I run it on v power. has anyone got any pointers so I may get somewhere near the original figures or is it a total engine rebuild ? thanks for your replies in advance.

If its otherwise running OK (no smoke, no rattles, no knocking and good mpg) don't think I'd bother with a full engine rebuild for a few extra hp? Presumably that's what the R32 is for, going fast?

The trouble with doing nothing is that you never know when you are finished.

1. Is that power figure at the wheels or the flywheel - think the 115bhp (or whatever standard is) is flywheel which would equate to about 95 at the wheels I think.
2. Rolling roads won't give an exact reading - they are interesting to compare cars with difference mods / engines and serve a purpose if you are comparing yours over time (for example getting a baseline reading and then adding performance parts and seeing the impact).
Things like wheels and tyre pressure (rolling radius) along with when the road was last calibrated all make a difference too.
The above certainly used to be the case 10 / 15 years ago when I was into such things.

the figures were at the wheels, Like you said you will lose a bit through the tansmission,, it has the original wheels with new tyresSvenM said
Probably a couple of obvious points but I'll make them anyway:
1. Is that power figure at the wheels or the flywheel - think the 115bhp (or whatever standard is) is flywheel which would equate to about 95 at the wheels I think.
2. Rolling roads won't give an exact reading - they are interesting to compare cars with difference mods / engines and serve a purpose if you are comparing yours over time (for example getting a baseline reading and then adding performance parts and seeing the impact).
