Mine was run at a place in chesterfield, brand spanking rollers and a pukka bloke and i was looking for some power i thought i was misssing, as it happened car was perferct and first time it was ran up it made 200 dead but we did multiple runs as we were checking afr's etc but we actually changed nothing at all yet each run it made just a nadge more power till the final run when it made 205 bhp...thats not the only time ive seen this either, you always need to do at least 4-5 runs imo to start getting a true reading and roller days only run once, twice at best.

Dave
I agree dave. A few runs are necessecary for the rollers to adjust for the car in question imo. Likewise i thought i'd be adjusting some parameters to gain a few horses when i went down to see matt but as it happened it made 210 straight away and ended at 213 after a few runs. I think matts rollers are pretty accurate as he reckons he put on his audi a3 which is factory spec and it made the exact figure the company quote. As we all know though rollers are funny things and can be different werever you go.

Phate is an unknown quantity at this point
Well I'll be happy to do this then. I'll get my car dyno'd where it was done last time and got 185.3 (this was before the exhaust), I'll get my remap done and go back to the rollers to see what it says


Now who wants to pay for my remap

mine was the same, first run at reidy remaps, with exhaust and induction, it made 179 bhp. i said to matt thats low so he re-ran it, second time round it was 184 bhp iirc???? my car gained 5 bhp in 20 seconds?? without touching anything.

whilst he was remapping it, he done 2 runs, one immediatly after the another , he didnt change anything, it was run on the same map and it lost 4 bhp. 5 minutes later he re ran it again and it made what it did the first time round.

rolling roads are never going be 100% accurate, they are just a rough figure.

another thing, superchips did a re map for the zs 180 that was supposed to gain 12 bhp but none of it was top end it was all mid range.
George knows his kv6's and he did 180 re maps that also showed no top end gain it was all mid range, roverdose also tried it with no joy...so if superchips and george and roverdose who lets face it all know their stuff, and all tried and failed to find extra peak power , then how come some bloke whos never seen a kv6 before can all of a sudden find a nice lump of extra top end power. ??

he gained about 12 bhp from mine. and a 11 ft lb torque. what ever he has done has definatally made a difference. its definatally better in 2nd and 3rd gear.

looking at my before and after graph, and looking at micks whilst i was down there, there is an improvement all the way through the rev range

So where has all of this come from then? A few weeks back it wasn't an issue and now some people have had success he gets questioned? Sounds like sour grapes to me. In order to question anything you will need hard facts to prove it beyond all reasonable doubt. Just because other 'experts' may not have succeeded does not mean they are correct in their assumptions or know their stuff.

In order to know something you must first understand it and therefore under the cause and effect.

Well if people have such an opinion no wonder we get nowhere with research and development, never give anyone the benefit of the doubt and experience. I went into this with an open mind and the result was better than expected. 28 years of engineering and a Masters Degree has taught me plenty and that is based on evidence and not bullshit.

altho....really.....whats the point in chasing numbers? lol whether you have 120bhp or 300bhp......it doesn't REALLY matter aslong as the car still puts a smile on your face my zed certainly doesn't fail in that area!
