crawl ratio ?

[oatsk5]

I searched but i dint read all of them but my question is is 37.95 a decent ratio i cant recall if its acceptable or not my gears are 3.06,2.72,4.56

allright for 35s-38s in my opinion.motor could be in the consideration. I have 6.69,2.62,4.10 with 33s It crawls good.71.86

I have a 700r4, and an np208... can somebody refresh my memorie on the gear ratios? Or in other words wuts my crawl ratio with 4.88's?

 

[muddybuddy]

ive got 3.06,2.61,5.13 (40.97 crawl) and im gona run 40's

beast...700r4 = 3.06, np208 = 2.61 ur crawl is 38.97

thanks bro

i will be running 65:1 with 38s. i think thats a decent crawl ratio.

I thought with an auto tranny you doubled the ratio because of the converter?

whats my ratio like i have a 89 blazer with a 700r4 and np241 and stock 10 bolts so probaly 3.06 i guess. and is there a website with this calculater around? thanks

Depends on if you want Timmay to scream ... I know he's joined the band now, but that used to make him froth at the mouth =))

I've also heard that, but it depends on the motor speed 'cuz the coupling of the torque converter changes with RPM, etc etc.

Hehe...Mine is 134:1.

Neener neener!

Oh! Make him scream! Make him scream!

Torque converters have btwn a 2:1 and a 2.6:1 torque multiplier when UNlocked (unstalled) and I would imagine that the actual ratio at any given time depends on how close to stalled the converter is. When stalled they are 1:1

It all depends on the setup especially auto or manual. You are running an auto so your crawl ratio is just fine. I am running 3.06, 2.61, 4.56 in my truck and I crawled the hell out of it in AZ and was never hurting for deeper gears offroad. I do have a low stall converter(1000-1200rpm) though and a torquie TPI 350. I had that converter installed especially for rockcrawling.

With my setup I never had a "need" for more gear. Sometimes more gear would have been nice but I never needed more gear. If I am in low range & 1st gear and the motor is doing 1100 rpm I am either climbing my obstical or spinning all 4 tires trying to climb the obsticle.

In alot of situations I almost wish I had less crawl ratio because that much gear with the fast throttle response and lowend torque of my motor was hard to control. I have to pay attention when I am crawling so that I finess the gas pedal because if I step on it the truck jumps hard.

I've got 68.88 with 44's... actually it WILL be that when I get off my butt and work some OT to get the gears installed.

Currently it's 50.08 and it's really not that bad to be honest.

153:1 is where its at stupid

mines 50.89:1 before doubling it, then add about 525 Ft/lbs of torque and 37 inch tires....

If only I could figure out a way to fit 5.86 gears in my 14b....

 

[tarussell]

153:1 is impressive but 241:1 is a tad more impressive........

Merry Christmas , Tom

holy ****.. i hope the TC means i have to multiply by 2. cuz damn

with a th350 np205 and 5:13s... i have an anemic 25.34:1

 

[jaysonsk5]

just did mine with 465,208 and 5.13. it was 87.7 is that good?
i can let the clutch out in 1st and low, it will dig without stalling.
oh yeah i run a mild BBC and 44 boggers
