fp green typical track times
the rule of thumb is to add 25mph to the 1/8th mph...if you're under 25mph that means the car is falling apart on the big end, knock, poor shifting etc..
if you're picking up more than 25 that means you're 1/8th isn't all it could be...bad 60' bad shifting etc..
this doesn't always hold true! but it's a rule of thumb
92-93mph in the 1/8 should get you ~ 117-118mph roughly

I've had numerous customers go to a dyno after being tuned and were pleased to see that their DLL numbers were lower then their dyno numbers...thats' because I put in a very conservative weight in DLL for myself and my customers.
I ran across a blog of another tuner and saw his DLL results from tuning customers cars... 16g cars on pump gas making 400awhp and other nonsense like that. He was putting 760lbs for the contents weight to artificially inflate the numbers for them.
the g-tech, DLL etc aren't perfect and only as good as the person setting them up but if done correctly and if you're being honest with yourself it can be a helpful way to gauge your gains


With a properly configured DataLogLab its very easy to say...I have set individual car definitions for all Evo VIII & IX models (GSR, SSL, MR, SE, RS) and the different gear ratios on the Evo VIII & IX models as well...and when i log some ones car with a different tire/wheel size i also throw those in the equation....AND i also account for the weight as much as i can (ie people in the car, no tire/jack, etc...)
Rock on in the free world Chris!

this time is really bad for those mods am running 12.95@106.8 and my 60 was 1.81 and my mods are Turboback,walbro,GSC s1 cams and flash tune you sould be running 12.00 or less and its VIII though
Just thought I'd throw my 1/8 time in there.
7.2@96 1.65 60' is the best... Average trap is 96... I've seen 97 once.
This is on 25-26psi with a fairly conservative tune. My trans let go on me last season so I've yet to increase boost to improve further. I have a pretty basic setup with some weight reduction.
If you're into 1/8 mile racing you should check out the 4.11 gear sets. They will allow you to hit 97mph @ 7500 rpm in 3rd gear. I can't wait to get a set... kinda OT i know!
