Post Your 40-70 Times!
i found this test on an rx7 forum(thanks to whomever that is)
i do not have an evo yet
or i would post my times
You need a flat straight away preferably one that would allow you to run it both directions so you can average the times to account for wind.
Start by maintaining a steady 35mph in 3rd gear. Floor it!
At 40 mph hit the timer...a stopwatch is fine.
Keep it floored and in 3rd gear.
Stop the timer at 70 mph.
Repeat as neccasary...careful it gets addictivley fun.
I'd be curious to see what mods do compared to stock times.
The Why:
We should'nt use 1/4 mi times as a gauge when talking about mods. The 40-70 mph in 3rd gear test is awesome for gathering test numbers.
It is easy to do and gets rid of launching and shifting vaiables. You can time your car, then do a mod or tune, and retest.
What is wrong with a dyno?
1. I don't have one.
2. This test is free and can be done nearly any time.
3. A dyno can't tell you what weight reduction has done. I get signifigant variance from a full tank and a 1/4 tank.
I think the 40-70 in 3rd gear gives us a cheap ...make that free, simple, and pretty reliable way to compare.
Happy testing.
This list will make no sense unless your mods are listed.

Make sure you list road conditions and outside temp too...and remember to do this on the freeway and on level ground so you don't get a speeding ticket
and so you're not cheating by going down hill
