I went 11.6 @ 118 mph. I think there's a thread on fastest SFWD cars on here, that should give you an idea.

my 12.2 run was at 109 mph

sounds like an ls tranny would be best for me if i plan to run 11's. ive read arguements that b16 trannies are better for turbo. i personally feel that it is too difficult to get the power to the ground with high HP turbo applications, using a b16 tranny. the ls gives you a forgiving margin of error. a gsr tranny would reguire me to shift just before the finish line. i think the ls is perfect.

I agree with you but 98% of people in here will not.

Every setup is different. Different people have different turbos.

http://www.fatboyraceworks.com/gears/

has a good gear ratio calculator.

I have a b16 trans. 4.05 final drive
24.5" slicks

so my 4th gear is good for 134.18 MPH. Good enough for me Now, just gotta go run the times.

here we go!

to run a long geared tranny is just like using one long gear. what I mean is, shorter geared trannies are tailered for our motors cause we don't produce this thing called "torque". A transmission multiply's torque which we don't have at lower rpm's. Real simply, Top Fuel and Funny Car use one gear(direct drive) why? Cause they don't need a transmission to multi torque get them down the track, they have a $hit load of torque. For some, an LS trans will work if the car is are extremely light weight and make tons of power. just my .02cents. shorter gears and narrow power bands

acura ls's dont have super high amounts of torque, yet they came with longer geared trannies, can you explain this?

can you elaborate as to why it only works for SOME? and what qualifies as TONS of power? i have a 96 hatch, turbo, and plan on seeing 11 second ET's.

oh no not the ls vs gsr vs. b16 bs again. Longer gears good for turbo- of course, riiiight yea it makes sense..... THEORETICALLY. The top 7 cars in SFWD/T4 (correct me if im wrong) are using a gsr trans/b16 or hybrid b16/gsr gearing trannys and maybe 4th or 5th ls gear . Theory is overrated, let it go!

LONG GEARS ARE NOT GOOD FOR TURBO CARS. SHORT GEARS ARE NOT GOOD FOR TURBO CARS. THE <U>PROPER</U> GEARING IS GOOD FOR TURBO CARS!

I'm sick of this long and short gears trash. Figure out your trap speed. Figure out your tire size. Figure out how many RPM's you're going to turn. Pick a tranny based on that, not just what you hear on a forum about how long gears are the suck.

I think people should just experiment........

Some trannies work for different people and different set ups...

also....times are posted not by power....but by "DRIVER SKILL"......

yes i agree about the driver skill part. it seems like it would be VERY hard to perfect shifts in a high HP turbo car using the b16 tranny. i guess ill learn... any one have price quotes on getting longer 4th and 5th gears for the b16?

I guess you didn't understand the whole "Top Fuel and Funny Car" and "Direct Drive" concept. I will stop here.
