M35A3 Cat 3116 Max Operating RPM

[EdMontana]

I cruse my A3 on I-75 with the cat from Syrose @ 55MPH. the tack says 2200rpm and it goes just fine. Remember the cat is not a chevy big block.

Check your real speed with a GPS, you will find out that you are not going at 55 mph.....

And the other poster....going 60 mph with a loaded A3?.....they must be some A3's with a modified tranny or too much sun in the head.

Your going to get a wide range of answers, but I run mine wide open.

So did the Army/NG. If you ever got behind a convoy with A3's in it, they weren't going 45mph.

Everything I read here says the 14.00x20's don't fit without a lift or mods.

What mods are you doing, and what are they going to cost?

14.00 x 20 no problem. 2900 rpm at 61 mph

That is on the A2, the A3 is taller. Some guys run 16.00 x 20 at 53" tall, the 14.00 x 20 are 49.5 tall. I will be cutting up my A3 i a couple of weeks to bobb it, all ready have the tires.

I don't think you can run 53" tires on an A3 unless you extend the dog bones to spread the axles or bobb it.

Yes, 46" is the max. for the 6x6. My latest pic's.

I found my speedo was way off. When I switched to 395 Goodyears I found my speedometer to be dead on. I verified it with a GPS. I typically run mine around 2400 RPM and 50 MPH.

I did check this with a garmin, your right the tach is off. THe cat I was driving belongs to Mogger67, I let him know today he needs to replace his tach.

Good intel thanks...!

Nice job on the alternator, I would assume the chargeing is much more effective coming out of the that rather than the generator??

i was not aware the A3 came with a generator?? almost positive it did not.
