    Nice! Putting down some serious power for R18's. Are you running an LSD? And who is currently the highest hp R18 known?

    Very nice build man! Go Jotech!
    So what rpm are you getting full spool at? It looks pretty soon based on your torque graphs, but they are using speed for the x-axis and i don't know the R18 gear ratios.

    No LSD currently, although it is NEXT on the list. full spool at 3500 once it kicks out of low and opens up.


    5-Speed Manual Transmission Gear Ratios: 1st: 3.143, 2nd: 1.870, 3rd: 1.235, 4th: 0.949, 5th: 0.727, Reverse: 3.308, Final Drive: 4.294

    Compact 5-Speed Automatic Transmission Gear Ratios: 1st: 2.666, 2nd: 1.534, 3rd: 1.022, 4th: 0.721, 5th: 0.525, Reverse: 1.956, Final Drive: 4.437

    i dont really know highest HP as different dynos etc read WAYYY differently. Like FR R18 on dyna has 251whp but only 221 wtq. so im SOLEY basing it off TQ and not HP as torque is required for HP and is used to calculate the HP. I currently hold the highest reading for the R18 at 231 wtq. this was colombia's stock tune to go get gas hahaha and realized the MAF housing restriction. all to be fixed SOOON!
