exactly we had real fuel i miss my nice grey tailpipe was the best way to tell when the HQ was running mint nowdays all you get is soot LOL

yeah but also now days you have fuel control for every 400rpm so the exhaust would be hard to read !!!

yeah just got me some nice near new 215/65/15's to slap on the rear and stick the old rear on the front ready to finish the roady

They'll be a bit taller than the stock 205/65r15's mate, you wanna kill some launch for top end? Might save an nth of gas on a trip up north/east tho

i worked it out they are only like 6mm taller LOL bugger all circumferance difference either

according to my spreadsheet this is the difference

assuming 3.08 diff and t700 gearing

215/65/15

100kms = 1722rpm and tyre of 661mm

205/65/15

100kms = 1756rpm and tyre of 648mm

roughly

if delcowizzids car turns out anything like my torana then changing a tyre size like that can make the world of difference in traction off the line! - mind you my increase in tyre size was 205/45/16 (591mm - 2156rpm) to 225/50/16 (631mm - 2018rpm) and this was all with a 3.45 diff.

she definately drives a lot smoother now havnt tested traction yet

and why the hell not

cause he hasn't got the turbo on yet

haha she still squeals the tyres must be soft they sound like they are still to try WOT traction due to the car having issues still going to find out why i have erratic rpm tomorrow shit weather out there today.got my oil pressure and temp guages today better than the temp guage that never moves now i just need an ecotech oil pressure spring so i can bump up the oil pressure and fit the guage and should be a bit more life in the old girl
