What is the difference between 3.55 and 3.73




















Similarly, a pickup with a 3. Those ratios provide very good acceleration with gas V-8s and diesels. Trucks equipped with 8-, 9-, or speed automatics may work well with 3.

How to choose the right axle ratio for the best pickup truck performance Axle ratio. Related Stories. Top Stories. Autonomous Walmart trucks running without safety drivers Self-driving autonomous trucks from tech upstart Gatik are now running without safety drivers for Walmart in Bentonville, Arkansas.

Pickup Trucks. Fuel conscious Ford Maverick hybrid pickup delivers 42 mpg city. Isuzu kicks off production of F-Series, including its first foray into Class 7. Neat huh? To make the 3. Of course the main focus here is times. If you look at roll-on acceleration times and mph acceleration times, they improve with every gear increment and that's where most of the hands-on driving will show in the way it pulls stronger in every gear it's really nice now.

I've only had the 3. With my old 2. With the 3. I can actually break traction in 1st AND 2nd gear! I wasn't watching the speedo when doing a few launches but it does seem as though I'm coming short of 60mph in 2nd and that I probably do need to be in 3rd to drive me through it, so the program numbers have made sense to me for my situation.

It does feel as though it needs quite a bit more horsepower to bring the power curve in-line with the new gear. With your '88 GT and 3. Can you tell me whether you do or not? If I were to keep the hp numbers stock, I would have also considered going with 3.

But I'm thinking Vortech in the future so I'm planning ahead but in the mean time, it's so much better having power available in every gear compared to the 2. With the 2. The ETs are flat. I'd run the 3. If you recall the data with the 4. Why did the '89 GT have better times as you increase in ratio? The gearing in the T-5 in the '89 GT is different than the gears in the T! The 4. How do the figures look now? Those numbers are wrong Lowering the gearing is going to increase torque multiplication and increase acceleration through the gears.

The only reason you would slow down would be lack of traction. If the sim. I apologize to everyone for my previous posts on this thread. In no way, did I intend to pass off the numbers as "real" figures. Someone posed a question on approximate figures and I thought that this little program could give him an idea of what kind of numbers he could expect to see but even then, I messed up because I didn't know there was a difference in the T-5 and T gears and am also disappointed at myself for even posting my opinions on this at all.

Desktop benchracing is no substitute for actual track-time which I have little on cars. In the future, I'll try to keep my opinions based on my own personal experiences. With that said, I am curous if anyone has installed 3. I had just had 3. What are your impressions on the 3. I'm going to get some 3. Highway driving is still acceptable. The one thing I liked about the 2. Now, 70mph is rpms, 80mph is rpms, and 5th gear is now a little more responsive when a short burst of power is needed.

Decent gas mileage is still possible but you can also go thru a tank of gas a LOT faster if your not careful. This week is not as good The one downside I am feeling is city driving; specifically when accelerating off a dead stop.

When driving conservatively, I try to make my shifts at rpm. But rpms in 1st gear is 15mph, and about 25mph in 2nd gear meaning you I lag behind in traffic. Some people may not care, but I do. I don't mind taking it easy on the road but I don't like the feeling of lagging behind in traffic when accelerating off the light. Of course the only thing to do then is shift at rpms but then your blowing a lot more fuel and making a little too much noise for "conservative" driving.

I think that this also has to do with the powerband of the 4. So the 4. I'm still working on restraint but this week it just got the better of me and I've been punching it a little harder.

I definitely like the 3. If I had 3. I think 3. Hope this helps give you an idea of what to expect. Reply to author. Report message as abuse. Show original message.

I'm just wondering about how much of a difference there is between these. For an example, let's say I have a stock car with 5spd and 3. The car also gets 28Mpg Highway, 18 Mpg city. Read my post on another thread discussing cartest. Sorry if this is a repeat.
