I did a fresh morning baseline with the Spectre intake + Corsa exhaust.<\/p>\n\n\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n\n

60′ time was 2.3 sec, so still not good.\u00a0 Unfortunately my pre-corsa cold air pre-run earlier in the week — also a 4.8s but 4.8s\/5.12s — there was no usable Performancebox data file to compare the details from (tech glitch).<\/p>\n

\nI did disconnect the battery yesterday to speed up relearn, but the transmission is still hitting the rev limiter before shifting on some runs. Over time I suspect it will adjust, although it may need to be tuned to shift sooner.<\/p>\n

My prediction is that the Corsa frees up 12-20 hp but I’ll have to get a better test run to prove that.\u00a0 Today’s raw data is no improvement over the 4.8\/4.9s posted prior to the new exhaust.<\/p>\n

The difference appears to be from 50-60 mph.<\/p>\n

Max calculated power on this 0-60 run was at 6105 rpm<\/p><\/div>\n

Max calculated power based on torque delivered for the morning caused traction control to come on at the shift — an unusable run because I had not switched it off —<\/p>\n

I plan to start recording Richard’s correction calculator<\/a> for runs so I have that info.\u00a0 Today was about perfect for a correction factor near ‘1’.\u00a0 I am using the air temp from IAT1 for the adjustment; Richard suggests use the actual air into the engine, which is IAT1.<\/p>\n
