Thats nifty, is it any where close to a "real" time?

Well I punched in a buddys time and power and it was lower by almost 1 second. The guy has an 89 Daytona with approx 500whp, car weights 3400lbs and so far hes only managed an 11.9. Granted thats not at sea level and its a fwd car.

Pshh, it says my car should do a 13 flat but the best I could squeeze out yesterday was a 13.8... Granted I was on heavy 16" wheels with bald tires that were discontinued years ago (read: aged and slick) so my launches suffered terribly... But still!

yeah doesnt seem to accurate....

well launches are everything! maybe thats why ???

but yeah there is too much thats goes into getting a good run to trust some calculator on the internet, still kinda cool to play with.......like 600 hp on 100lbs car. lol. but like i said too much comes into play: wheel/tire size, tire pressure, fwd or rwd, altitude, yada yada blah blah etc etc........

dc2696 Jul 23, 2006 09:54 PM

It errs on the side of being faster thats all.

dc2696 Jul 23, 2006 09:57 PM

for my car, I have done lots g-tech runs and (when it was n/a) and ran 15.6 on the street and it says that I should have 110whp...Possible on a 1.8 with intake exhaust I suppose.

Cheesefries Jul 25, 2006 07:55 PM

seams decently accuate to me, i did a couple friends cars and it was all correct assuming PERECT conditions/driver

sounds reasonable to me

dc2696 Aug 9, 2006 11:30 AM

The thing with the g-tech is you have to launch properlly, no wheel spin/hop has to be smooth.

ColoradoSpringsMiata Aug 25, 2006 09:14 AM

oh thats why it seemed unrealistic when my friend used one, he always dumped the clutch. i didnt know that. hehe

ienjoydrifting Sep 10, 2006 09:01 AM

yea its says my car will do 11.9 lol. Yea after 6 trannies and rear ends lol

I learned after my second diff to go bigger, no trannies yet though.

ienjoydrifting Sep 11, 2006 09:57 PM

Yea i have a RX7 ats deftforce 2 way now. No more breakage

Braineack Sep 22, 2006 11:21 PM

try this instead:

magnamx-5 Sep 26, 2006 12:58 AM

i have to much wheelspin when i dump the clutch it is kinda funny:)

Braineack Sep 26, 2006 08:40 AM

you can have it optimize the launch. It seems to take a lot into factoring times. not sure if it's any more accurate...

magnamx-5 Sep 27, 2006 12:44 AM

if i had a better reference for friction coeficient i could optimize it to the grip of my tires but this still doesnt take into acount wheel hop i get if i realy lay into it from a start.i obviusly havent done this to often as the dif still works knock on wood but once or twice just to see what she would do:bigtu: :eek4:

magnamx-5 Oct 23, 2006 06:30 PM

yeah i need to get a torsen and test that software agianst real life.:bigtu:
