cannot wait to see your times
good luck.

 

Ive had my F since the beginning of the F and started modding it at 14000 miles... didnt happen over night.... this lastest burst didnt even cost as much as a full set of carbotech track pads... that i daily

 

Nice, what other mods do you have?

 

Totally stock just the diff

 

I know MRxSLAYx already posted a little about this, but here is a quick side by side reference of the speed/rpm differences you can expect with the different final drive ratios discussed in this thread.

 

nice, i'm all stock other than the joe z exhaust, should be a good race,

 

Guy tell me if i'm mistaken, the guys that run headers have to either shift into 5th or redline 4th to finish the 1/4mile with the stock diff, now looking at the above chart, does that mean guys with the 4.09 diff will have to shift to 6th to cross the line? if so might hurt a little bit

Caymandive goes into his 11.91 run in this thread. Yes, he bumped on the rev limiter in 4th at the end of the run. After looking at the numbers, yes an ISF would have to shift into 6th w/4.09 gears...the extra two shift might hurt more than the gearing helps, but I can't speak intelligently to that topic. I am not very experienced or well read on anything technical with drag racing.

 

Much better than my concoction lol

 

What tire size is the chart built on? You can get around some of these late shifting issues with larger diameter tires.

 

Your still in 4th when you cross the line with headers.

Theres no way the time it takes to shift in a ISF two more times will out weigh the gain found from a 4.09 final drive. Old drag cars gain .5 - 1 second from final drive jumps like that with a old school 4 speed. You might loose that time in traction issues though... we are soon to find out.

 

I calculated those numbers with a 26" tire.

 

I'd be inclined to do something like this if I were drag racing:

 

IMO I really think the new is350 gearing is going to do more harm than good. I believe that the gearing for our cars is actually too short for drag racing, and is really going to hurt on the back end.

 

dv8ation let me know next time you go to the track, i'll join ya!

This is crazy, everyone here is like a big reunion... Jeff form the supra forums.... Other guys here from the GTA where I just moved form, the VT guy going to napierville (in QC).....

Hahha I love it,

Anyways, don't you guys find that first gear is too short for dragging? Many times high horse power mk4 supra's just launch in 2nd because first is a write off...

I'm surprised you have traction even with ET streets with one tire spins with these trash elsd.

I really REALLY REALLY want to ditch the ELSD for a stock torsen...

Anyone wanna sell me theirs? LoL
