VT_Maverick's 5 Speed Swap

[vt_maverick]

Checked last night and 60 MPH was about 2300-2400 and 70 MPH was roughly 2700-2800. IIRC from the trip 80 MPH was 3100-3200. How does that compare?

Awesome, thanks for checking.

I spent most of my drive with the cruise set at 60 on the speedo, but thanks to my 35's, my GPS said I was doing 72 MPH. I was right on 2500 RPM.

Bigger tires would lower the torque rating at the rear wheels. IOW, making it feel a hair less powerful. Plus, we've yet to see anyone report an improvement in MPG from larger tires. Looks and traction are cool though!

Pretty darn close to stock. IIRC, the 5th gear is the same as 4th in the stock automatic. So, it stands to reason there won't be any difference on the hwy.

Yeah I've come to realize that there aren't serious MPG gains with the AR-5 in highway driving. But the fun-to-drive factor and (hopefully) better reliability still make it well worth it IMHO.

On 35's with 4:77's...(All values in 4th, TC locked)

55=2k

68ish=2.5k

Pulling trailer, 13.47 mpg best recorded on Moab excursion.

Oh yeah, it accelerates way slower than it did on stock size tires due to the extra weight and change in the gearing. Mileage wise, I only ran about one full tank through it on stock tires and got 16 MPG. I've been getting the same 16 MPG average with the 35's so far.

On my trip to Moab most of my tanks I got 16 MPG as well. The best I got was one tank of 20 MPG, which was the last tank coming into Moab. I think it was 'cause I was driving a bit slower coming down Hwy 6 and I had the TOD off. I left the TOD off the whole way home and didn't notice any mileage difference.

Doesn't seem to be. I wish we could get a 6-speed with a super low 1st gear for crawling and a nice long 6th gear for highway cruising. The fun to drive factor is certainly a nice feature of the 5-speed though.
