what aftermarket apex seal would you choose?

i've personally run the Goopy seals up to 13.5:1 AFR at 500whp(not saying a whole lot but most seals would have failed in this scenario), the seals did not bend or crack. it was only for a few dyno runs before i noticed the pump dying and AFRs spiking but they handled it just fine. 91 pump gas with 50/50 water AI spraying only about 500cc/min at 24psi.

i've never needed to put them through more stress than that but dozens of installed sets floating around that have not failed so far(i have never had a set warp or break or even gouge the housings is what i'm saying). they don't push selling their seals all that much so you won't hear a whole lot about them.

but take my opinion with some bias, since i am one of their resellers. if you do choose them i can get you a 25 bucks off off retail with shipping included.

i would not recommend Atkins seals in anything other than a stock turbo or n/a engine, even that is pushing it. i've had many sets break over the years even under very light detonation cycles. they are weaker than OEM at handling detonation but in the event a seal or 2 does fail the damage is minimal. if you don't mind some possible damage and love ripping engines apart i suppose they are fine, and also the cheapest option. i only use atkins seals now on n/a engines since they last the longest.
