Ok to try and make it clearer
This is the
WHEEL horsepower from my car before and after uprev
I am realistic and wasn't expecting massive figures, this is my first N/A car after owning a couple of Skylines R33/R34 and an Evo 6 which were all highly modified but I thought it should make 20-30hp more , hell even stock I thought it would be 260hp at the wheels
If you compare my chart with a manual 370z with similar mods
PLUS Berks high flow cats on the same dyno
(These are flywheel calculations of course)
I do have a set of test pipes I can fit , but will i really pick up 27hp and 20 ft lbs by fitting them ? Are the stock cats really that bad ?
