That's pretty good Frank. I'm sure it will get better once she's had a gallon or so through it.

You want someone to summarize 900+ posts? Some might say if you don't have the time to read yourself, you don't have enough interest.

Try this.

Big bucks
Good mileage
Decent performance
Decent engine life

The new speed is a big jump in power over the old speed. The new xz-b has much milder timing numbers compared to the old v spec but seems to hold it's own in stock form. The only problem i'm seeing is the same gripe i had with the older v spec/speeds, gets low on compression early on. I run my engines crisp and have run speeds and EB v specs for years and have had to replace the p/s/r every 4 gallons. I still have a worlds speed and will continue to rebuild it cuz i damn sure like it. Never had any luck pinching an OS. I need another truggy engine so i just might try a Clockworks XZ-B.

Man, I never have any compression problems. OS's will never have compression like a nova or other Italian engine, but they always run great for me even with little compression. I've yet to get less than 7 gallons out of an OS p/s. I love the fact that they don't have the ridiculous metal pinch that nova's have. I'd rather have an engine that breaks in quick and runs 7 gallons than an engine that takes 3 gallons to fully break in and runs 10. I just can't waste that much time on break-in. When I break in a new engine I want it ready now, not 3 gallons down the road.

I know you guys will never hear it, but the 20% fuel I run might have something to do with it.

my pinch on my speeds do wear but not as fast as you stated what break in method are you using I use the heat cycle work great for all my motors. Also I don't normal pinch but after one set with two gallons 30% Gen2 and the pinch is still super tight which was very surprising since I though it would be gone after a gallon also used the heat method 3 tanks before retuning. Didn't believe in pinching but after this set I'm a believer.

My 1st speed went into it's 10th gallon before it started to flame out. Next p/s/r set went abt 6 gallons. I had a few speeds at this time. The worse it got is when i switched from byron's to nitrotane. I had 3 good engines lose all compression after 3 gallons of nitrotane. Right now i fitted an older piston to a sleeve that's been holding quite well. My worlds block also got ruined after a supposed "high quality" after market front ceramic bearing locked and spun in the block ruining it. Never had a problem with answer-rc engine bearings, only the bigger buck brand. Lesson learned. So here's what i got, a used v spec block, a crank from my 2nd speed cuz my worlds crank cracked across one of the slugs, a 3 gallon old lightened EB Mods rod, an old v spec piston matched up to an old speed sleeve with the original EB modded back plate and head button and the cooling head is original. How does it run? Just like it did when new after Ed modded it.

so is it 4 gallons,6 gallons or 10? So is it a OS problem or is it your choice of fuel? your posts seem pretty contradicting and confusing.

Oh you must be bored Joe. 1st engine went past 9 probably cuz i ran it richer. Next sleeve only got 6 since it was leaner. After that some poor fuel choices. Then i must say there was a time when new p/s sets were subpar. Your engine man was getting news the big boys in Cali were lucky to get 3 gal outta the p/s sets. Now he wouldn't bullshit would he Joey? How's that .23?

No hard feelings, i really like OS engines. My EB modded speed always has been a stellar performer. It was modified and bench break in by Ed and ran on EB Mods fuel. Compression done by the 4th gallon. No fault of Ed. I'm sure it was all me, lol.
