Hi has anyone here built an engine with all the powerseals parts (apex seals, semi solid corner seals, solid side seals & reusable o ring kits) ? Im doing a whole new rebuild and Im not sure using what my previous setup had (super seals, atkins solid corners) or going with all the powerseals products since I bought new housings and irons. Any feedback will be appreciated

 

fastest rotaries in drag racing are using powersels parts .i have use their apex seals and they work great.

 

I have zero experience with Powerseals, but I think the more relevant questions when choosing apex seals and all the other internal hard seals should be what objectives are you building the motor for? Will it be a street driven car with less than 350~400RWHP when all is said & done, or will it be a track beast with significantly more power than that? Similarly, how often do you expect to have to rebuild the motor, and how aggressive or conservative do you plan to go on the tuning? In other words, if you choose to run a very aggressive tune to eek out that last 1% of RWHP, your risks of blowing a motor due to detonation/knock tend to go way up, and you'll be doing rebuilds more often.

So the choice of seals needs to consider two major considerations: (1) How well do they seal and how long can you expect them to maintain acceptable compression for the motor's use case over its expected life?, and (2) When they do fail, what is the typical failure mode - i.e., do they break apart at failure, and thus take your housings, rotors & possibly turbo out with them, or do they just bow in a bit and loose compression, which tends to spare the housings, rotors & turbo?
