Lets look at the mods then.
custom 4-2-1 - Gotta be worth 5bhp
decat - Again at least a few here, lets say 5bhp
stainless throughout - Another 3bhp here?
panel filter - None really butlet's just say 1bhp for sake of arguement.
ported and polished head - THis should easily add a good 10bhp, if it's a good one maybe even more.
reprofiled cams - Depends on spec, lets say a 275 and another 5bhp
and been remaped to suit. - Probably a couple of Bhp due to get the fuelling bang on.
So 112bhp standard plus my rough guesses above = 143bhp
If it's a more metal cam and the map on the ecu is really well set up I can't see why 150 isn't possible. Sure RR's can be a bit over but I really can't see why everyone is bashing this. THere are plenty of 8v's out there producing this kind of power, my MKII should be 140 ish and that's only a 1.9.

mk3 8v is 115hp standard, and 4-2-1 mani can give far more than 5hp. Ask danny_p. His abf was RR'd and at the time the only modification was a custom 4-2-1 manifold, 150 bhp standard, his pulled 173hp, so thast 23hp from a manifold, although I find it hard to believe only one thing would give such gain.
When I had mine RR'd it pulled 116.6hp, only modification at the time was drilled airbox. It hadnt been serviced in 25k miles, and it was running 95RON. I reckon with a full service and some v-power I would have been able to scrape 120hp, and that is completly standard. Now ive got piperx panel filter and more holes in the airbox, alogn with cold air intake and soon to have decat and chip, I am expexting around 125-130hp.
