Well, at approximately 4:31 EST, Dr. Rotaryman88 hereby states Time of Death to the SE-X motor...after hours of ATF and hi revs, steam treatment, and everything else Dr. Rotaryman88 could do...the rear rotor only produces one WHOOSH of compression...thus the sign of only 1 to 2 existing APEX seals :(...it didn't give me the clean, whoosh - whoosh - whoosh that the front rotor produced...well, at least now I KNOW I'm gonna be replacing the motor!! I've got til July 21st....my goal will be T78 competition street port w/ 2peice 2mm seals...or maybe 3mm..we'll see how my next few paychecks are, lol...

They die so young.....I am picking up my 88 today, it has a new motor, transmission and other assorted new stuff....cant wait to drive it...I will be eating bread and water for awhile... https://www.nopistons.com/forums/pub...

that sucks atleast you finally know it is the engine..... now to start the new project https://www.nopistons.com/forums/pub...#>/biggrin.png

Yea...new project, lol...didn't finish the first one..its kind of all turning into a big blur now. What are you all's opinion on Atkins Rotary? I helped a buddy of mine swap an Atkins SP motor into his '91 T2 and it had a bad front oil cover seal or something, and we had to ship it back..alls good now though...just wondering if anybody had some advice or stories about Atkins? I'm looking for the quickest way to 500RWHP right now...and not having to assemble my own motor will save me a lot of time...and then I'll just keep the blown block and rebuild it when I can and save it as an extra, lol....

Rotaryman are you from around here? Washington? Just curious, I have heard good things about Atkins, never taken anything there as Hayes is about a block from my work... even though they charge some pretty steep prices.

turborotors engine was an atkins rebuild.... the front rotor bearing broke! if your gonna spend the money go with http://www.pineappleracing.com . heard nothing but excellent things from them https://www.nopistons.com/forums/pub...IR#>/smile.png

How did the bearing go bad?

well he drag raced it but our guess is the reused the bearings maybe that one had high mileage on it. who knows :(

Did it break or did he just spin it?[/quote]

it broke. when the engine ran RAK RAK RAK RAK. it sounded nasty! ito confirmed it too :([/quote]

Either the bearing was defective, there was an oil problem, or the motor was over revved.[/quote]

he thinks he might of over revved it on the burnout with the haltech rpm limit set to 16000 rpm https://www.nopistons.com/forums/pub...>/rolleyes.gif[/quote]

Yeah, everybody always likes to blame the engine builder. https://www.nopistons.com/forums/pub...>/rolleyes.gif Stock bearing won't handle much more than 8500-9000.

If they put new bearings in the motor then it would require an extended break in period. Did they tell him exactly what they replaced?

nope he ordered the new engine not exactly knowing what he was getting it was a long time ago

I've seen that they sell rebuild kits with new rotor bearings. Using new rotor bearings with used rotors isn't the greatest thing and can require an extended break-in. I'm just trying to figure out why it went bad because I'm curious. I always see so many "mysterious" engine failures, like my friend's which has blown 3 times since November. :o

It wasn't just that drag racing. I been over revving my car a lot before that, usally taking it to 8k everytime at the track. Then after i put in my 9k tach from an 89 and didnt' realize i was taking it to 9k then. Part of it is my fault for over revving.

Don't worry i have the rev limmiter set at 7k now.

For the next rebuild you could try getting upgraded stationary gears and bearings. You could try the race bearings that RB sells for the rotors. There's a little bit more to do, but you'll be able to go to 9K no problem.
