The top speed of the Jato 3.3 out of the box is very fast, with a few tweaks it'll break 70 MPH. How often do you find yourself hitting 70+ MPH though? IMO I'd rather have torque than speed, I find myself using it much more.

    I've got a 3.3 4-Tec, but I doubt I've ever had it past 50 MPH yet, just bashing around instead of risking my car trying to go as fast as possible.

    LOL, yeah Revo, those tires were an attempt to find a tire that wouldn't wear out tread so quickly.
    Pros: Tread is appearing to last almost forever. No question about wheelies(could prolly pop wheelies even sittin' on 2 stix of butter) decent high-end. Very good handling, really no spills whem wheelin and also high-speed turnin'(note--dont recommend using the same size tire for fronts)
    Cons:Stock tranny gears life will be shortened in my experience.
    Very fun for playin' in the yard and various surfaces, wheelies on everything with 20t clutchbell/ stock 54t spur.

    I wish that there was a place around here to run in the dirt like a track or to get top speed runs in.

    So you're saying the 3.3 doesnt have enough low end? If you are, you are clearly wrong. The 3.3 has a very nice power band through all RPM's. If you look at a Jato box, it says 0-60mph in 4secs. It has plenty of low end power. If the OS has more low end, who cares? You will probably flip the truck on its lid with more low end power. If you want more low end, why not just gear down or get the 3.3 modded?

    I have 2 Jatos. 1 is strictly for on road, high speeds. The other is for off-road. They both have 3.3 motors in them. When I drive my off-road Jato, I find that even the 3.3 is too powerful to be driven in dirt. I cant imagine how a OS21 would be off-road in a Jato, probably horrible though. Maybe if the Jato was
    4WD, having an OS21 might be a better idea.

    To me, having any huge engine is a Jato is pointless. I know people like to be unique and try different things and thats fine. But I see it as overkill.

    The problem you have with top speed runs is distance. With the power and gearing I have, it will probably take 300 to 350ft of straight flat surface to hit top speed. The lot I run in is 25 parking spaces about 250 ft., and you need 25ft to stop. At about 225ft, I was clearly still picking up speed when I had to slow down. I installed my wheelie bar upside down yesterday and the wheels almost touch the ground. That should get me to second gear faster without 50mph wheelies. High of 65% tommorow, will try it out and get some video if it dries up.

    Good idea about the upside-down wheelie bar. That crossed my mind the other day. I'm gonna try that as well.

    try the new era wheelie bar upside down. The newera wheelie bar is good on street but don't try it off road when you are flipping, it bends.

    That's the one I have. Did you try it yet on-road upside down? How did it work?

    I see where you're coming from, I had a 2.5 in one of my Jatos and just sold my 3.3 Jato (traded, actually). The 3.3 is very powerful, and has a lot of torque. The 3.3 in my Revo got it going pretty well, and my 4-tec is an absolute tire shredder with the 3.3, but like you said if he wants another engine more power to him.

    WOW I thought the metal gears would hold up with no problem. Are the ebay bronze one everyone is talking about any better?

    I thought the same thing. Just so happens those gears are made of aluminum compared to the bronze Jatomadness gears on Ebay. Bronze happens to be the strongest and hardest metal alloy you can get other than steel, and is corrosion resistant. Much better than aluminum, justifies the difference in price of the two sets, but does not inlcude the rear differential gears.

    Are those aluminum gears from HOT Racing? Aluminum gear to aluminum gear in a high torque load application is not normally good. What happened to those gears is exactly what I was affraid would happen. My Jatomadness gears showed up today and they look nice, hope to try them out soon.

    I think they are hot raceing but I don't know.
    Maybe I could give my friend all my tranny gears and the diff cover and have him make them out of steel. It could be a asignment or something for him. Or I could wate afew years till my 3rd year in highschool and make them then.

    Keep us posted on how they perform. I notice they don't include the differential gears like the aluminum set. Is that a problem, or is it just the four gears they include that typically cause all the problems? My CVD's came with new spider gears, and the differential seems fairly strong.

    Yes, these alum. gears are Hot Racing. Tom, notice the gear I'm holding in the last pic....no notches in it to be able to adjust the gear change timing when installed in the tranny case!!! Back to square one for me......knew I shoulda bought those Bronze gears. I'll probably end up replacing with the plastic stock over and over.
    I check the slipper several times throughout a session. I know its not locked tight. I about to throw my hands up and go for something else :/

    Actually it looks like to me that Jato madness may have left the diff gear plastic intentionally, something need's to be the sacraficial lamb LOL!! I haven't actually stripped any, but a friend of mine went tru 2 plastic sets and it waisted the same ones as pictured above in the aluminum.

    I have Jatomadness saved in My Ebay, and the gears are not available right now. I have watched them for a month or so and he usually relists them a day or so after the auction ends.

    I agree, that makes a lot of sense to do. I just checked and the diff gear set is less than $7 on Ebay. Not to bad if they don't go often. I looked at his feedback, and you would think he has sold a ton of those gears, but I could only find about 6 or 8 sets sold. Wonder why, when so many have tranny problems?

    I think they probly sell them somewhere besides just Ebay, have you tried emailing them directly about buying the gears? I would like to have just the aluminum diff plates but so far I can't get Hot racing to sell just the plates. The only way to get the plates is to buy a full set of the gears that come with them and I don't want the plates bad enuff to buy the complete gear set.

    Yea, when I was going to be the gears I e-mailed them a few times. Kinda slow, but they responded back. Didn't know enough about it at the time to ask about the diff gears, but did ask about larger clutch bells, and he was going to try and get some made, and let me know. Don't blame you, that is two much to spend for just the diff. gears.

    OK guys, I promised some video today, and here it is. This is at tank 10 w/25% nitro and slipper 1 1/4 turns out. Tune is ok, but still slightly rich, w/temps at end of run 223%, w/header loose. Believe me, it still has a lot left.

    BTW, please don't flame my lovely wife on the camera, she did everything she could to keep up.

    Tried the upside down wheelie bar trick. That experiment failed miserably. Wheels just to low to the ground to gain traction, just spin out. I will try to just put it in a vice and bend it down a little. That should do it.

    It's totally un-driveable now. Even with a working wheelie bar....why would you want to do wheelies all day? You can do that with a 2.5.

    Whats the point of such a big motor again?

    You don't need it man, you just want it. The factor is off the charts. If you say that is undrivable, you definatley couldn't handle my revo with the .27 in it. I intentionally punched it at the worst possible times to test the tranny on video for everyone to see it is holding, maybe not for long... but it is.
