I know your pain. lol

 

If you want to "reduce the strain" on your motor, downshift to the next gear! Why are you trying to pull a trailer up a hill in a high gear just because a "stock" truck can? You don't have a V8 or diesel, you have a 4 cylinder engine. Smaller engines have to rev higher than larger ones. Engines are made to run so why are you afraid to run it??

 

Thats not the point!

 

So the point is you screwed up choosing gears because you talked to one person about which ratio to get instead of doing your own research?

 

OK, My dads factory 87 toyota can go 85 in 5th before running out of power, I cant get over 75.

 

Yes
I talked to whom I thought was an authority on the matter so I chose the wrong gears. Yes

 

How much more does your truck weigh then his?

 

When you go up this hill, put it in third...report back.

 

Then what are you hoping to accomplish with this thread. People are telling you the reality of the situation. We all have different opinions of what a motor should and should not do and what should and should not be done to a motor. If you are unhappy that you can't pull a small trailer like a stock truck I see 4possible options. I am sure there is probably more than that.
Option 1-Buy a stock truck and use it just tow with
Option 2-Put your current truck back to stock so it will perform like a stock truck.
Option 3-Do a V8 engine swap an get the torque you want.
Option 4-Buy a diesel full size truck and never worry about that again

But don't tell people that's not the point when they are just trying to help. That attitude isn't wanted here. Pirate4x4.com is a better place for telling people that when they are trying to help you. Right or wrong remember they are trying to respond to a thread you posted to start with.

 

And to be honest...4.88 is plenty of gear for a 33. 5.29 is way to high and you'll be rapping out the motor all the time.

You have the right gearing...now you just need to learn how to use it.

 

Yup, thats my point. If your trying to get your "factory power ratio" back with the extra weight and higher rolling resistance of larger tires, 4.88's arent enough.

 

Hmmm you have a weber, and is your dad has a 22re?

More horsies out of the fuel injection.

Did you tune the weber for the altitude? I had a 32/36 and it was finicky.

Also, HP is not increased when you change gearing. You need horsepower to go up hills at highway speeds. BUT your truck has bigger, heavier tires and more drag, so it will need MORE hp than your dad's to hit the same speed. But since its a 22r it has less. So there's that.

I can say this, all the trucks I've had with various combinations of 30,31,33 tires and 4.10 or 4.88 have all pretty much climbed the passes at the same speed. 3rd gear and 65 mph.

The gearing multiplies torque which will help you at slower crawling speeds and around town. Not on the highway.

All that said, I have 4.10s with 33s right now and for highways it's great. Actually awesome because at cruising speed my mileage is REALLY good. BUT I wish I had lower gears for camping and around town stuff - in fact I'll probably put 5.29 in there when I have the cash.

 

"Rapping it out" as in driving up grade at 4-5k rpm?
If I had the proper gear ratio I could putts up grade at 45 pulling a trailer like my fathers factory truck.

 

No, my fathers truck is Asian carbed. Ive been thinking about going to a Webber 38 but dont know if it will give much increase in power.

 

Im not trying to be an ass, Im frustrated because everyone keeps talking about driving techniques. Im talking about comparison. I know every rabbit trail between here and fort peck, I dont need speed, Im just comparing performance between two similar trucks.

 

Should I have my father put his in third too so we can compare them properly?

 

I think the 38 is overkill for this motor. A 22 can't flow enough to make use of it. Especially if you aren't revving high.

What's the story on your carb? Did you jet it?

I think if you can't get to 75 right now something is going on and it's not an issue of tires and gears. No reason that should be trouble for you with 33s no matter what the gearing is.

 

Yup, jetted it, its running awesome.
As for high revs, its still a new motor. I'll rev it higher when Im convinced its broke in better but yeah, maybe with a little tail wind I could go a little faster. Maybe with a longer stretch of flat road I could convince it to go faster too but the end result is, Im not interested in going faster anyhow. In fact, speed is completely out of my idea when I built this truck. Its my round town/ mountain truck. I have 7 miles of black top till I reach the base of the mountain and 14 miles of black top getting to my sons house. Thats basically the extent of my high speed driving. I just threw that in there because everyone was talking about driving techniques and that wasnt the point.
The biggest issue with highway speeds is wind resistance I think.

 

Nothing wrong with a good debate, lets just not let it get out of hand. I have seen several good points made and try to respect each one.

 

Good post right there, I agree
