Default I believe it works out to 57-91. Mark P has a tire calculator on his size, not sure how accurate...

between different tire manufacturers and so on.

Default 340-350g/s straight from MAF, no correction to be applied whatsoever

My car makes power on timing, not on boost, I'm only holding 18-19 psi at 7200 RPM.

Default I would tend to bend my head a tad when you say your car makes power on timing vs boost

but your midrange is in the 5's, your not making power on timing down there

Default 3.37 on a 2.87 run.

Now however, this is actual speed derived from RPM/mph, not speed read from the ECU which is useless because of tire sizes being so different to stock.

I've raced a "normal" stage 3 S4 running about 430 crank and super lightweight (recaro pole position seats, no rear seat, no spare wheel, lighter driver) and the difference was 2 carlengths in 3rd, 2.5 in 4th. Every time he gets above 6k RPM I gain on him just because mine pulls straight into the 7400 RPM limit in every gear, whereas his power tapers after 6500.

Default Power isn't in the midrange though ;) Torque is...

and this is where boost will always do a better job than timing IMO and IME....

Just trying to get clarification timing on both sides is steller and your GS is nice.

Default In my newest templates I'm going to add an "FYI start speed / end speed" to the FATS data...

This will display what the recorded start & end speed was that corresponded to the 4200/6500 RPMs for that run. This will just be some informative data, which can then be applied to the new "Any speed range calculator" that I've added.

This way, we can get a feel for what the MPHs are when most of us log FATS, and then other people in non US-6speed-B5-S4s can take those speeds and put them into my speed calculator which will then give them a corresponding method to see how long it takes them to accelerate the same.

Coming soon )

Nice times! 6psi drop from spike? Seems like you'd be even faster without so much drop?
