FATS Times?

[scheides]

Has anyone ever done any testing for FATS times with their car? I'm hearing from some audi guys that this is how they measure how quick one car is vs another (to take out driver interaction, etc in quartermile times and whatnot).

What this is is a time measurement. You measure how long it takes your car to to accellerate in third gear from 4200-6500rpms. 7.0 is slow, 5.0 is fun, 3.2 is quick. I imagine (for some bigger turbo guys) this could be expanded to do a 3rd gear run on a evo/dsm from say 5000-7300rpms (i.e. a 2300rpm sweep).

Any interrest/history in this? These audi guys are crazy for it, I thought it'd be cool to setup a website that anyone could post up their car make/model/mods and fats times.

Here's an example site (audi punks):

Never heard of it before until now. Seems like a decent idea, but it can't be used to compare non-identically geared cars. For it to work, there would have to be a seperate database for FWD and AWD DSM's.

RPM sucks, it should be mph. My gears are STUPID LONG compared to a dsm's.

Hrm, true true. But if you did it in a gear that had a *close* to 1:1 ratio, would it not matter?

Yeah, then why don't we all just dyno and then calculate power to weight ratios ;).

I think a xxmph-xxmph would be a better comparison, at least you can compare between cars then. The only drawback then would be a possible shift bringing driver ability back into play. I think human-error in time recording would be huge though.

Just another way to bench race. :)

They don't like the dragstrip? Their gear ratios and tire sizes would have to be exactly the same for it to mean anything.

It would be hard to do with DSMs and Evos with all the different gear ratios from FWD to AWD, from manual to auto, from Evo 5-speed to Evo 6-speed. A MPH range might work, but you would need to find soemthing that would fit the stockish guys who don't rev higher versus the big turbo guys who don't spool until 5500+ in 3rd gear but might rev to 8500. Even MPH can get thown off a lot by different tires.

The dsmlink guys use 70-90 mph times as a judge. under 2.0 sec is considered fast. mine runs around 1.7 on pump. mph seams better then rpm IMO.

Yes!

Tell them to hit the track and practice.
