   just with a bmc, 4-2-1 and a de-cat. yea im quite happy really - my mates MI16 made 161BHP with 160ish Nm of Torque so im quite happy with the torque side of things. Just wanting cams and a remap now
   
   EDIT : Also happy that there's no dip in the Torque line like there was with most cars there.

    yea sure mate it was at street racers in leicester which were actually nominated 1 of the worse rollers in the country for reading too less.
    but in the summer i got my car dyno'd on some dyno dynamics rollers and it come out at 121.7 HP with 110.3 FtLb. (with exactly the same mods as now)
    But it was about the hottest day of the year aswell.

    standard at the wheels should be around 100. Roughly 20% transmission losses

    In that case Gearbox / Driveshafts or something is wrong. From that RR your engine is making good figures, but the power isnt getting onto the road!!

    yes mate, having spoken to John he suggested somewhere between 17.5% - 20% it should be.
    
    On mine with refurbed gearbox and new driveshafts it was near enough 17%

    If you want to know what gains you are getting of any modification you should always do a before and after as no VTS these days will get getting spot on 120bhp. The power will actually go up as the engine gets warn in and then drop off as its starts getting warn out. Its perfectly possible to have a completely standard car show 130bhp.

    My engine had done only 15k when I bought it. It seems to be getting more powerful all the time. It's done 60k now. It's ran 708s since about 30k I think.

    You've gotta remember that 120bhp is just an average taken from an x amount of engines tested by pug.
