This engine is a beast! More power and tunability than any engine I have ever ran. I also can pit between 8-9 minutes in a truggy on a fast track.

I don't race but most of the guys I bash with run LRPs or Piccos. I thought those were powerful until I showed up day with this and blew the field away. lol I was skeptical about the price but as others have stated, it's worth every cent.

I bought this engine for my Losi 8ight T 2.0 RTR, The Losi 454 that came with the car was fast, but this thing is extreme and i only have 2 gallons of fuel on it now. I changed the venturi from 9 to 7 mm, and for now i get 8 min runtime, dont know how much less it will use after some gallons more, but i like the fact that i have to tune it down to make it drivable. I drive here in Spain and the race finals last 30 min, i should be able to make it with 3 fuelstops. I also belive that with r[More…]

We have two of these in losi 8T truggies. Run times are 7.5 to 8 min., the only complaint I have with them is they kill drive line components, lots of power. Using 6mm carb insert tamed it down nicely, and comes off 7 min. qual. w/ 1/4 tank left in it. Nice engines.....

Most guys at my local track suggested I stick with Italian engines and that OS wasn't a reputable brand. During break in this engine did not miss a beat and tuned with ease. All the guys were impressed and some had never even heard of the 28XZ. After making a couple laps I was impressed and had their attention. Needless to say I'm not hearing any more comments(negative that is) about OS. The power it puts out is incredible and had to put in the smaller carb insert to keep it manageable on the tr[More…]

Just broke in this engine and all I can say is WOW!! If you're looking for a mill with insane power and speed so much that most will tune it down a touch for track running (atleast for our shorter track) This is it!! If you bash or street race or anything to the sort and you can afford a higher priced mill you don't need to look any longer You will not be disappointed.I have the Trinity Extech .24 Full Modded great for milage not for power I wish I would have just listened and bought this to beg[More…]

I have 2 of theses mills and both of them are killer mills both have over 2 gallons with no slop anywhere.only miner thing i had was the carb boots leak, but some lucky seven seal fixed it.......if you like on the edge of out of controll power this is the mill for you !!!!!!! no bull here

After a month with this engine I am very impressed.. The only complaint I have is the fule mileage, but what do you expect with a .28 engine. I am working tuning it down. Just ordered a 6mm and 7mm carb inserts to help wrangle this thing in. And, if it is possible this engine makes too much power... Hard to get it to hook up. But, the power w/8mm insert is ultra smooth, and screams from bottom to top with a JP3 pipe.. I have this installed in a Jammin X-1 Crt. I'm going to try a few diff[More…]

This engine is incredible. It pulled my Inferno GT to 68.5 MPH @32,500 RPM. Easy to break-in and tune, and it's coming even stronger on the second gallon. This is the best engine I've ever owned.

I shoe horned this monster in my Revo...... wow! Took a few mods, but well worth the time I spent. Runs sweet and more power than needed, just how I like it.

i got this engine for my mugen mbx5t and it is just a monster!!! then i bought a mbx6 and just for the hell of it i put it in there and holly sh!t. it pulls wheelies on the paved road and it is just insane, from the top speed to the quickness. if you are looking for power get this! Good luck

This engine is insane!!! I bash a Jammin X1-CR with this motor, 20T clutch bell, 48T spur (stock), and buggy street tires. Ill be looking into a 46T spur soon because the motor has no problem reaching redline. btw, I do not use any restrictor. O.S. currently holds the title for baddest engine EVER!!

OK, now this motor has crazy power, to much for an everyday racer, I race here in Colorado and between the 7 tracks we have here 9 out 10 people who run this motor all agrre that its to much.... great for the muggy or LST but for a truggy I run a 6 mm restrictor and throttle at about 70%, No matter if Im up against the GRP, Nova, RB or vspec, with theses settings I still have plenty of power to move around the track, neck and neck on our 220 ft straightaway, and clear the monster 50ft table top.[More…]

This motor is nasty the power is crazy it almost rip the tires off my truggy I use OS 2060 pipe nice top end as well as bottom end grunt. GOOD STUFF

I have the old ninja 28's, this definately revs out higher with a much more useable smooth power band. Just like my v-spec with more power. I run the red 7mm restrictor and its insane, you don't need bigger unless your purely bashing. It eats 21's at the top aswell as the bottom. This is by far the best engine I have ever owned. Price is also fantastic for a new breed top end 28. Still running rich and I get 9.5 minutes to bone dry tank. I estimate 11 minutes is up for grabs which makes 20min ma[More…]

Im thinking about putting this engine in my muggy is it worth it?
