SRA what gears?

[Andrade]

i got a SRA swap out of 98 cobra in my 03 .. it has 3.55 in it now.. but for drag racing what would you guys recommend ?


i was thinking 4.10 would be a happy medium for driving on highway and also great running down the track?


this car is most def not a Daily Driver its a weekend warrior and gona index and grude race my buddies at the track with it

I'm at the end of 4th goin through the line with 3.73's if that gives you any idea

 

[Andrade]

appreciate it .. what does your car make? run?

i like my 4.10s better than my 3.73s for the 1/4 mile dragstrip. i was winding right at redline crossing the traps. this on a 26 tire, 450hp with a 120mph trap speed

but overall daily driving the car, i think i prefer the 3.73s because sometimes cruising on the highway at above 80mph the car seems a little too high strung with the 4.10s

best of luck with it!

Really depends on trap mph and tires size. I chose 3.73. With my 26" tire and low to mid 130s trap my shift light is flashing.

730/660 at the time..on some sh*tty 275 nittos I trapped 134 w/ a 2.4 60'...a lot more tire now for this year:dancenana:

I have had the 3.55s in the solid for a couple of years.
Was on 26"ET Streets and 28 ET Drags.
Best time was 10.05@138
Recently installed 3.73s and made 2 test passes.
Off the trailer I ran 10.2@137 with an easy launch and no power shifting.
The 3.73 is more ideal with the 28s for racing.
Hope to really lean on it tonight at the track.

I have 3.73's in my solid axel and love it really not much of a difference from the stock 3.55's

 

[timspony]

3.73's perfect IMHO ... like the 3.55's second!

I ran the 3.73's for a couple of years and they worked fine. I was in the 125-128 range most of the time trap speed wise and that was 6100+ with the 3.73's in 4th going through. I switched to a 3.90 for this year to see how it goes. I have a feeling that I will either end up running 27's or raise the limiter a couple hundred rpm. Maybe both. We shall see. I will find out next Saturday if all goes well.

Sweet lookin more like 3.73 for me

 

[JDUB348]

Just got done with my sra swap and i love my 3.73's.

3:55 for me... but im making 600hp and still going
I had 4:10s in my IRS and my SRA came with 4:10s and I dont like em... shifting all day, car seems to run out of gear quickly not to mention the noise 4:10s make. 3:55s will be going in for me.

Ran 4:10's in my SRA with a 28' Hoosier, don't fear the gear ;-)
