FuzzFace2 Posted August 22, 2020 Author Share Posted August 22, 2020 Looks great! I've only gone for a short ride, but I agree, the carpet makes a huge difference, enjoy it! Wife wanted to go out for dinner so I made her work for it While I drove and yelled out numbers she wrote them down, here goes. Speed Direct OD 40 1300 1100 45 1500 1200 50 1700 1300 55 1800 1400 60 2100 1600 65 2250 1700 70 2500 1800 75 2700 2000 80 3000 2200 I don't know why the 1800 in direct or the same RPM for 50 & 55 MPH? I have 1 tanks full running at 65 MPH like I did with out overdrive but now have AC that has been running non-stop. Anyway I only pulled 14.8 MPG, I was getting high 14's to mid 15's before the overdrive.

Bet it sounds like a completely different truck inside cruising at 65 with the OD on. Link to comment Share on other sites More sharing options...
FuzzFace2 Posted August 23, 2020 Author Share Posted August 23, 2020 Great info Dave. Bet it sounds like a completely different truck inside cruising at 65 with the OD on. Yes it does just wished the MPG were up a little bit. After the next full tanks I plan on doing the speed limit of 70 MPH for a few tanks to see where that gets me.

Doing some simple math, dividing the Direct # by the OD #, gives the following ratios. I think the 1.31 - 1.39 ratios are probably within the limit of your tach and ability to read it. But the readings from 40 to 55 are very suspect - unless you shifted gears. Speed Direct OD Ratio 40 1800? 1100 1.64 45 1500 1250 1.2 50 1700 1700? 1.0 55 1900 1900? 1.0 60 2100 1600 1.31 65 2250 1700 1.32 70 2500 1800 1.39 75 2700 2000 1.35 80 3000 2200 1.36 Link to comment Share on other sites More sharing options...

Then went into OD and did the 80 to 65 or 60 and did the rest of the drive on the high way at 65, speed limit is 70 MPH there. On the way home I took "local" roads with the speed limit of 45 to 55 MPH so I did the 40 to think 55 in direct then shifter to OD to do the rest of the numbers. I will have to recheck them numbers as something just did not add up. I should have rechecked them when we were out but we were just enjoying the ride. I also was showing her were I have made some LP drops and on roads I had not been on before. Figured I would post what I found so others would know "ruffly" what I was getting in what gear.

Dave ---- Dave, I think your wife is just screwing with you! Gary would understand 'taking the piss' in his Brit lexicon. ETA: having a laugh, at your expense.

Sac79 Posted August 24, 2020 Share Posted August 24, 2020 I guess I know a much lower class of Brits than you do. Nothing unexpected.. Yeah Jim, Gary must have interacted with lords and ladies... 'Taking the mickey' is the less crass version, but what you said is definitely what I heard and said the most... And it sounds like the OD is working out great Dave, enjoy it!
