TR-3160 Possible on a 05-09?

[blacknsilver05]

I went with the 2.97 and 4.10s. Keep in mind, this is a street car.

But, I did lots of research before coming to a decision. On the street, goosing the car at about 2000 RPMs is common for me, so I used that as a starting point to decide. I then prepared an Excel spreadsheet showing the cars speed in each gear at 2000 RPM using my (then) stock 3650 and 3.55s.

I then did the same with about every rear end gear combination and both T-56 combos (2.66 and 2.97).

I knew I liked the feel of 1st with the 3650 and 3.55s, but I wanted shorter 2nd and 3rd -- while keeping the final drive gear of the new trans (6th) similar to the current final drive gear of the 3650 (5th).

That's how I ended up with 2.97 and 4.10s. 1st is nearly identical to what I had and 6th is very close to the old 5th. But, 2nd and 3rd are wonderfully better

Do you have that spreadsheet still?

EDIT: I’ll do a screenshot and post it here

Hopefully this works. Keep in mind, the speeds shown are based on my rear tire size, so your results might vary some. I used the calculator on Tremec's site for this. So, if your tire size is different, it would just require you taking the time to go to the site, input the correct data, and start comparing.

It posts, but clicking the image to enlarge it isn't working.



If you don't mind, may I suggest a couple of things?

Round the speeds off to whole mph (as numbers, no decimal places).

If you're computing based on the tire size or its advertised diameter, include a downward 3.5% correction (100 mph calculated becoming about 96.5 after correction but before rounding). This accounts for tire tread compliance effects and usually matches up very closely with tire revs/mile given by the tire mfr.

Well, I got what I got . . . no going back now on the trans/rear gear combo, LOL.

But, rounding up on the spreadsheet is an easy lift. But, rounding down 3.5" on the tire would mean going back and using the calculator on Tremec's website again for each combo.

 

[Norm Peterson]

Not necessarily.

Make a new chart that multiplies every mph in your existing chart by 0.965, copies the non-numeric stuff directly, and only publish the factored table. Maybe put it on a separate sheet and label the sheets, or add to the label in the table heading so you know which chart you're looking at.

Okay, if it helps anyone, here is the same sheet with all values multiplied by .965 and rounded to the nearest whole MPH.

Stock I agree but what about a bottom end that isnt stock?

cylinder heads/cams are a problem. cam drive. tensioners. Roll the dice with MMR stuff? Probably just wasting money.

Makes sense. With that being said, as my car sits I have full bolt ons and stage 1 NSR's waiting to be installed. Does the 6060 align well with my car? or am I sacrificing acceleration? I also have 19x9.5 that have not had tires put on yet which may be helpful for you guys to know as well.

Wow read through that whole thread. Seems like more of a pain then it’s worth for just a weekend street car. Well then Racer do you think a 6060 will align with my goals for the power I shooting for? Or do you think the 6060 gearing is too long and will actually slow the car down? I have 3.73’s right now in the rear end.

I agree. If someone gave me a free 3160, I may spend the money and effort to make it work. But if you have to pay what it worth, the 6060 is the better choice.

For a normal street car, the stock 5 speed and 3.73's are really not bad. I ran like that for a long time. I only switched because I started road racing the car and wanted tighter gear spacing.

If you want a 6060, I'd go with the 2.97, 1.78, 1.30, 1.00, 0.80, 0.63 ratio. IMHO thats the best gear set. Thats what I have and is probably the most popular.

Here's a gear calculator that should provide everything you need and more.

At those rpm you’ll need to start to worry about the top end

Does anyone sell quality top end upgrades that could handle higher RPMs?

 

[stkjock]

Springs and rockers I believe so. Manley and Jessel IIRC respectively

I have a 6060 with 4:10's and the 2.97 gearset and I think it is a great combo. After running it for awhile I'd almost want to go with a 4.30 gearset.

FWIW the only reason I switched to a 6060 from the 3650 is because of the extra torque from the Procharger. If I was N/A I'd keep the 3650, just put in a better clutch.

I have same setup, did not realize how many other with the same. Tremec 6 speed with 2.97 ratio and 4.10 rear gears.
Currently pushing 18 to 20 lbs boost with KB 3.2

Surprised how well it lauches on the street with 305/17 Mickey Street radials.

This seems the perfect place to ask
Im about to swap a 2013 6060 2.66 gear
Does anyone know the correct driveshaft length? I have a brand new in box ford racing shaft and am hoping it can be shortened to fit.
Also what clutches did you go with?

Whatever length the GT500 driveshafts are. I bought a Dynotech aluminum 1pc when I did my swap. I have a Mcleod RXT clutch with their lightened steel flywheel.

 

[Racer47]

The 6060 is 0.7" (iirc) longer than a 3650. Most aftermarket driveshafts have enough travel to cover that difference. I used the same alum driveshaft when i went from my 3650 to 6060 and there is still plenty of travel left.

That's awesome news, what type of driveshaft did you have. I have the ford racing one (I believe made by spiecer) sitting in the box since last summer.

Edit-- what year 6060 did you put in? I think the output flange on the 13+ is different and cannot be swapped as it's 40 spline vs 30somthing on the earlier
