I originally found club lexus, but they seem more interested in hella flush and 20's
I appreciate the help, I'll see if I can ask JBrady some more questions. As an engineer, I tend to ask a lot of questions, and seeing data helps. If there's dyno charts of with and without cats, it'd be cool to see.
Spinnetti, I know your speedo is a bit off from the final drive but can you estimate what rpm your seeing at 75mph? My SC400 has a slightly shorter 4th gear so im seeing 3,000rpm at 75mph. Maybe 2800 on the LS?
good info, thanks. This is funny but now I understand why I got a speeding ticket a few months back. I was clocked going 95 in a 75! I was judging my speed based on the transmission speed sensor so I was assuming I was around 85mph but now knowing that I was genuinely doing that speed, i'll lay off the gas from now on. I have been told the trans will tell the ecu a different speed so my top speed is cut a bit short but im wondering ig I can trick the VSS with a resistor to squeeze out some extra top end.
you should have been going SLOWER than indicated, not faster.... mystery there.
