Coldest run, hottest run or somewhere in between?My tuner goes by the "hottest run" which is obviously going to be lower so just interested in knowing what is common practice.

Never had any say Panda I <3 Floods Silver Donating Members 11,198 Member For: 13y 3m 15d Gender: Male Location: South West QLD Posted 16/04/15 12:22 PM Share Posted 16/04/15 12:22 PM Cause he tunes cars for a living.So my way of looking at this is:Two cars,Same mods,One with ET Streets,One with Linglongs,One could be manual,One could be auto..Both could be within 5rwkw on the same dyno but guess what the difference is on the 1/4..I think some dyno readings could be largely inflated which is where guesstimating with 1/4 mile power calculators come in and can maybe be used as a reality check or maybe use them to back calculate effectively how much of your cars power you are using. Ie: dyno tells me I have 310rwkw, 1/4 mile indicates I have 209rwkw maybe I need to look at getting the power down better. Link to comment Share on other sites More sharing options...
